Important Things About Plastic Injection Molding Machine

Since the injection moulding process was invented, the plastic industry and the big business opportunity of injection molding have become a commercial enterprise which is potentially thousands to millions of US dollars. Injection molding has given an important role in the development of the economy in the USA. This allows industrial and consumer goods to be important for many industries, with affordable and durable prices.

Injection Molding Machine Function

This machine can be classified into three categories, namely: Multipurpose machine, precision machine/narrow tolerance and high-speed thin-wall machine. These three types require assistive equipment to function. These supporting equipment include dryers (resins), handling equipment, granulators, temperature control and mold cooling, handling equipment and parts extraction robots.plastic mold company

Many companies are specializing in quality injection moulding, but not all are identical. The best, fast, flexible, and customer-oriented, in both large and small quantities. These companies usually have state-of-the-art facilities with large scale thermoplastics and thermosetting capabilities, computer-assisted manufacturers, qualified machine operators, and quality assurance equipment.

Knowing The Components Of Injection Molding Machine

In general, the basic injection molding machine consists of a mold system, control system, injection system, hydraulic system, and Pinpin system. The tonnage clamp and shot size are used to identify the dimensions of a thermoplastic injection molding machine, which is a major factor in the overall process. Another consideration is the thickness of the mold, pressure, injection rate, the distance between the binding rod, and the screw design.

Injection molding machine converts raw plastic granules or granules into final mold parts using thermoplastic smelting, injection, conditioning, and cooling cycles.

Adjusting The Injection Mold

When you or your company need a plastic product of a particular type and size, you should go to a custom injection molding company. This manufacturer can create plastic components for specific applications: they can adjust almost all plastic components according to their needs. They can place your logo or message, produce unique colors and designs and pack them to your liking and needs.

Select A Custom Injection Maker Company

Most custom injection molding companies can make all the plastic products you specify, but not all of them make an extra effort to process  “settlement services,” such as decorating, assembling, labeling and packaging. Some even have a design group that can help customers design plastic parts and molds. From manufacturing prototypes and quick tools to injection molding, to plastic and ultrasonic welding and stamping, these companies can help you in every step. Choose a factory that offers this additional benefit. You can minimize spending, optimize effort, money and time.

Check the programming of manufacturing companies and logistics systems. They should be able to manage their shipping needs, no matter how demanded they are. You should also look for companies that apply strict controls to monitor the entire process of molding custom injection. They must have the latest inspection equipment to allow them to meet the closest tolerance and thereby provide consistent quality.

Plastic Moulding

plastic mouldingPlastic moulding is the plastic work through the Injection moulding machine, The melted plastic will automatically molten after erupting out in all of the plastic moulding methods, injection moulding has been the most widely used. The method comprises the following steps: getting the thermoplastic plastic or the thermosetting plastic imported into the heating cylinder of the injection moulding machine, and when it is completely melted, it will produce heat and frictional heat by the pressure of the plunger or the screw, and is injected into the mould cavity of the closed mould, after curing, and then open the mould and take out the finished product.


Plastic Moulding Knowledge Guidance

1 The basic knowledge of plastic molding.
1.1 The characteristics and composition of plastic injection moulding.
Plastic Injection moulding is to fill the molten moulding material in a closed mould with high pressure. The pressure that the plastic molding cavity needs to be subjected to about 400 KGF / CM2, approximately 400 atmospheres. With such a high pressure to make a product is its characteristic which is not the only an advantage but also disadvantages. In other words, the mold always has to be made stable, therefore its’ price is always high. So must be mass-produced in order to buckle with high-priced mould costs. For example, the production of each batch must be more than 10000PCS to be reasonable. In other words, plastic molding work surely has to be a mass-production.

A few steps of the plastic molding process :
1.1.1 Closing
Close the security and then start moulding
1.1.2 Clamping mold
Moving forward the moving board in order to get the mould closed. When the mould is closed which means is also locked.

1.1.3 Injecting (including holding press)
The screw is quickly pushing forward, injecting the molten formed plastic material into the mould cavity to full fill it. Keeping the press at the same time after full filling it, this action is particularly named “holding press.” The pressing that the mold has to bear when it just gets full filled, generally called ‘Injection Press’ or ‘one press’.

1.1.4 Cooling off (and the next step of the plasticization project)
The process of waiting for the material getting cool formed in the mould cavity is called “cooling off”, At this time the injection device is also ready for the next step, this process is called “plasticization process. The moulded material is placed in the hopper, inflow into the heated tube to heat, it is based on the rotation of the screw turning the raw material into the molten status.
1.1.5 Opening the mould
Move the moving board to the backward and the mould will be opened.
1.1.6 Opening the security door
Opening the security door, then the machine will be in the standby status.
1.1.7 Picking up
Taking out the product, checking carefully if there is anything left in the mould cavity, and this whole forming operation is called moulding cycle time. The finished product is shaped by the shape of the mould. The mold is composed of the left mould and the right mould, These two sides of moulds are left with voids, and the material would flow into the voids and get compressed to finish the product. There are three main lines of the path of the molding material before it flows into the left side and right side, sprue, runner, gate, and so on.
1.2 Injection molding machine
Injection moulding machine is distinguished from two large projects, they are divided into two, clamping device and injection device.
1.2.2 clamping device
Closing the mould, the molding material would be cooled off and solidified in the mould cavity. Opening the mould cavity and take out the finished product is the action of the clamping device
1.2.3 Injection Device
Injecting the plastic material into the mould cavity called ‘Injection device’

 

The following describes the ability of the injection moulding machine, there are three provisions to distinguish the ability of it.
A. Clamping force
When the injection is made, the mould won’t be opened by the maximum clamping force, expressed as the number of TON.
B. Injection volume
The weight of a shot is generally expressed in terms of grams.
C. Plasticizing capacity
A certain amount of time able to melt the amount of resin, this is generally expressed in terms of grams.
The most important part is the clamping force, the area of the moulded article is referring the mould perpendicular to the shadow of the opening and closing direction (basically the moud’s area). The average pressure within the mold added to the projection area is called the clamping force. If the mold “projection area × average pressure” is greater than the “clamping force” then the left and the right side moulds will be pushed out.
Clamping force = projection area × average pressure within the mold In general, the mold can withstand the pressure of 400KGF / Cm2, so base on this figure to calculate the clamping force, but the clamping force often based on the shape of forming materials and the shape of the product’s vary, the difference between the larger parameters such as PE, PP, PS, ABS materials, these raw materials are used to make the shallow box, the parameter is 300KGF / CM2, , if the depth of the box is deeper then the parameter is 400 KGF / CM2, If it is the small but high precision products. The projection area is about 10CM2 or less, its parameters are 600KGF / CM2. The smaller parameters such as PVC, PC, POM, AS materials, these materials are also used to make a shallow box, the parameters of 400KGF / CM2, if it is a deep box of its parameters is 500KGF / CM2, if it is a small and high precision products, projection area of about 10CM2 below, its parameter is 800KGF / CM2.Chinese molding company

How Much Does Injection Molding Cost?

Plastic Injection Molding Cost

Plastic Injection Molding Cost

If you are looking for the plastic molding parts for your new project, I believe the most important thing you want to know what will be the cost for the plastic mold and injection molding parts. Because all of this cost will affect your project going smoothly and success or failure. To carefully check this before you are running a new project if the project fails you will lose lots of money and time.

Let me give you some idea to help you understand plastic mold and plastic injection molding cost, this will save your time for your new development products.

The other easy way to understand those costs for your new project will be sending us your 3D part design or sample pictures, and tell us your requirements, like material for each part? Estimate the number of parts per time? Any special surface requirement to the visible side?

We will send you the best competitive price, we could offer the lowest mold cost $550, molding part cost $0.1, you could have this as a reference for your product and market research, welcome to contact us by [email protected]

Plastic Injection Molding Cost Guiding Tips

There are meanly four parts of cost: Plastic Material Cost, Molding Production Cost, Plastic Mold Cost, Part Color Cost, let us explain those four mean costs one by one.

Plastic Material Cost

First, the plastic material cost is determined by the weight of material that is required and the unit price of that material. The weight of the material is a result of the part volume and material density; however, the part’s maximum wall thickness can also play a role. The weight of material that is required includes the material that fills the channels of the mold. The size of those channels, and hence the amount of material, is largely determined by the thickness of the part, the selection of the material affects the unit part price as well, a different type of plastic material has a different price, for example, PP material is a totally different price than ABS material, so the material cost for plastic part includes two parts, one is the weight of the material, one is the type of material for the plastic part.

Second, the injection molding production cost is primarily calculated from the hourly rate and the cycle time. The hourly rate is proportional to the size of the injection moulding machine being used, so it is important to understand how the part design affects machine selection. Injection molding machines are typically referred to by the tonnage of the clamping force they provide. The required clamping force is determined by the projected area of the part and the pressure with which the material is injected. Therefore, a larger part will require a larger clamping force, and hence a more expensive machine. Also, certain materials that require high injection pressures may require higher tonnage machines. The size of the part must also comply with other machine specifications, such as clamp stroke, platen size, and shot capacity.

Injection Molding Production cost

The cycle time can be broken down into the injection time, cooling time, and resetting time. By reducing any of these times, the production cost will be lowered. The injection time can be decreased by reducing the maximum wall thickness of the part and the part volume. The cooling time is also decreased for lower wall thicknesses, as they require less time to cool all the way through. Several thermodynamic properties of the material also affect the cooling time. Lastly, the resetting time depends on the machine size and the part size. A larger plastic part will require larger motions from the machine to open, close, and eject the part, and a larger machine requires more time to perform these operations.

Plastic Mold Cost

Third, the plastic mold cost has two main components – the mold base and the machining of the cavities. The cost of the mold base is primarily controlled by the size of the part’s envelope. A larger plastic part requires a larger, more expensive mold base. The cost of machining the cavities is affected by nearly every aspect of the part’s geometry. The primary cost driver is the size of the cavity that must be machined, measured by the projected area of the cavity (equal to the projected area of the part and projected holes) and its depth. Any other elements that will require additional machining time will add to the cost, including the feature count, parting surface, side-cores, lifters, unscrewing devices, tolerance, and surface roughness.

The quantity of parts also impacts the plastic mold cost. A larger production quantity will require a higher class mold that will not wear as quickly. The stronger mold material results in a higher mold base cost and more machining time.

One final consideration is the number of side-action directions, which can indirectly affect the cost. The additional cost for side-cores is determined by how many are used. However, the number of directions can restrict the number of cavities that can be included in the mold. For example, the mold for a part that requires three side-action directions can only contain two cavities. There is no direct cost added, but it is possible that the use of more cavities could provide further savings.

Forth, the plastic molding color is also cost effection to the molded parts, normally does not have too much effect, but this is still depending on which parts color do you require if you need white color for your plastic parts, then the cost will be 10% more than another color, if you require clear color (transparent molding parts) molding parts, then the cost will be 25-40% high than normal color molded parts. When you need white color molding parts, then the molding shop needs to clean the barrel very well, and not allow any other color max in this injection unit and material, this will take time and waste some material, and the other thing is the waste rate will be increased, that is the reason the white color plastic parts is little high than other colors. When you are looking for transparent molding parts like PC injection molding, or PMMA, PS molding parts, the molding shop needs use special injection unit to produce this type of molding parts, they need to clear the unit barrel very well and use some good quality injection molding machine to produce the clear plastic molding parts, because any tiny molding defects on the transparent molding parts will be easy to identify, so you need to make the best quality molding parts, the waste rate is higher, and need to use the high tech injection molding machine, and all of those are more costly than normal molding production.

Injection molding Color Cost

Cost Estimating mothed for plastic injection mold and molding parts

1. Feature-based estimate

This feature-based cost estimator is for the plastic molding of production quantities (over 10,000 units), where more durable and costly tooling can be used due to its small impact on the per-part cost. The material cost is estimated from the part geometry and uses current material prices. For the production cost, a compatible injection molding machine is selected from a database of over 50 machines and the cycle time is estimated from the part geometry, material properties, and machine specifications. For the tooling cost, a suitable mold base is selected using standard mold dimensions and mold classes, and the required mold machining is estimated from the part geometry and other user specifications. These three costs (material, production, and tooling) are calculated for 4 different cavity arrangements (1, 2, 4, and 8 cavities) and the most cost-effective option is provided.

2. Low volume injection molding cost estimate

This feature-based cost estimator is for the injection molding of low volumes (under 10,000 units), where rapid tooling methods (high-speed machining of Class 104 molds) are used to create the mold due to the large impact on the per-part cost. The material cost is estimated from the part geometry and uses current material prices. For the production cost, a compatible injection molding machine is selected from a database of over 50 machines and the cycle time is estimated from the part geometry, material properties, and machine specifications. For the plastic tooling cost, a suitable mold base is selected using standard mold dimensions, and the required mold machining is estimated from the part geometry and other user specifications. These three costs (material, production, and tooling) are calculated for 4 different cavity arrangements (1, 2, 4, and 8 cavities) and the most cost-effective option is provided.

3. Standard estimate

This standard injection molding cost estimator does not require any part geometry but requires more process parameter inputs to calculate a more accurate estimate. The material cost is estimated from the part and runner volumes, an up-to-date material database with pricing, and customizable process parameters. For the production cost, the cycle time must be specified, as well as the machine rate and labor rates. After adding the mold cost, a detailed cost breakdown is provided for the material, production, and tooling costs.

4. Plastic mold cost estimate

This feature-based cost estimator calculates the mold cost for plastic molding. Based on the part geometry and mold requirements, such as the number of cavities, a suitable mold base is selected using standard mold dimensions. The required mold machining is estimated for the selected SPI mold class and rapid plastic tooling methods may be chosen for a Class 104 mold or so low volume products.

Plastic Injection Mold Press

Plastic injection mold pressPlastic injection mold press is simple called press. Plastic injection mold press holds the plastic mold in which the components are shaped. Mold press is rated by tonnage, which expresses the amount of clamping force that the machine can generate. This pressure keeps the mold closed during the injection process. Tonnage can vary from less than 5 tons and big than 5000 tons, with the higher figures used in comparatively few manufacturing operations.

Plastic injection mold press can fasten the plastic molds in either a horizontal or vertical position. The majority is horizontally oriented, but vertical machines are used in some niche applications such as insert molding (go to https://www.plasticmold.net/what-is-insert-molding/ to know more about insrt molding) allowing the machine to take advantage of gravity.

Plastic injection mold press is used to create many things such as milk cartons, packaging, bottle caps, automotive dashboards, pocket combs, and most other plastic products available today. It is known that injection molding is the most common method of part manufacturing. It is ideal for producing high volumes of the same object. Go to https://www.plasticmold.net/injection-moulding/ to know more about injection moulding.

Some advantages of using Plastic injection mold press is high production rates, repeatable high tolerances, the ability to use a wide range of materials, low labour cost, minimal scrap losses, and little need to finish parts after molding. The materials you can use in injection molding are chosen based on the strength and function required for the final part. However, each material has different parameters for molding that must be considered.

 

If you are a plastic parts manufacturing company that produces anything from toys to car parts and you are not using Plastic injection mold press to produce your parts, you will spend too much money.  Indeed, using Plastic injection mold press provides additional savings to manufacturers because plastic is less expensive than metal and manufacturers pay for fewer parts. As a result, they are widely used because of the high quality of the end product.

One of Plastic injection mold press you can choose in the market is Plastic Injection Molder (YS-1180). This machine has moving platen featuring box type bridge structure and full-connected rear high-rigidity mold platen. Through finite element analysis, it can prevent deforming of mold platen, resist against fatigue, have high repetition accuracy, distribute mold closing force uniformly, greatly increase mold’s service life and reduce injection molding cost.

Another option of Plastic injection mold press is HDT-200 200ton plastic injection molder. This machine comes in two series; HDT series and HDF series. The HDT machines’ clamping force is from 80 tons to 2200 tons and the shot weight is from 80g to 2kg. These machines have strong locking force and a very good injection precise also a stable performance etc.

Meanwhile, the HDF machines are a type of high-speed Plastic injection mold press. The machine’s cycle time is very short (2.6 seconds-3.6 seconds) with a high injection pressure (to be possible to reach 240MPA) and a high-speed injection (to be possible to reach 600MM/S). This machine can be used to produce the thin-wall products, especially the thin-wall snack boxes and containers (with the wall thickness of 0.4mm).

Or you can choose another option among other Plastic injection mold press available in the market. Just choose the one based on your needs and budget, and you will surely find the one you are looking for.

The injection molding process and plastics industry have truly become an incredible, multi-billion dollar industry, and injection moulding has made possible the cheap and durable construction of various different consumer and industrial items which have had a profound impact on society.

They are a company whose goal is to educate both customers and engineers as much as possible by providing information regarding manufacturers, resins, materials, and anything else that is related to injection moulding.

The Equipment Used in Injection Molding:

Their products include mold waxes, polyvinyl alcohol or PVA film-forming barrier solutions and mold polishes and buffing compounds, and mold cleaners. What is good about these products is that most of them are environmentally friendly and only contains ingredients that are non-hazardous.

Injection Mold Makers is a method of molding in which the molding material is first placed in an open, heated mold cavity. The mold is then closed with a strong top force or plug member, and pressure is put on to force the material into contact with all of the mold areas, and then proper heat and pressure are maintained until the molding material has completely cured.

The Plastic Mold Maker process employs plastic resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms. It is also important to understand that Plastic Mold Maker is an incredibly high volume, high-pressure molding method that is suitable for a variety of different purposes, including the molding of complex, high strength fiberglass reinforcement.
