How Much Does Injection Molding Cost?

Injection molding is a widely used manufacturing process that involves injecting molten material into a mold cavity to create complex and precise parts. if you need injection molding parts, it’s crucial to understand the injection molding cost. By gaining insights into the factors that influence injection molding cost and implementing effective cost reduction strategies, businesses can optimize their production and maximize profitability.

Plastic Injection Molding Cost

Plastic Injection Molding Cost

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 raw material cost will effect the plastic injection molding cost, it 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 raw 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 machine process cost will effect the plastic injection molding cost, it 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 Processing cost

The cycle time will effect plastic injection molding cost, 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 and design feature. A larger plastic part requires a larger mold, more expensive mold base. the complex part design requires complex molds, that will effect the mold cost.

The cost of machining the cavities is affected by nearly every aspect of the part’s geometry, complex mold cavity requirement lots of CNC machining cost and time, that will increase the plastic injection mold cost, on the other hand will increase the plastic injection molding cost as well.

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 injection 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 plastic injection molding 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.

Injection molding Color Cost

Forth, the plastic molding color is also cost effect to the plastic injection molding cost, 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 injection 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 injection molding parts like PC injection molding, PMMA molding, or 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.

Custom Injection Molding: An Overview

Custom injection molding or injection molding mold parts is a plastic part fabrication process that involves injecting stringent quality material into a mold die or cavity designed specifically for intended applications. This process allows design manufacturers to produce parts in low volumes to bulk. Generally, it’s also known as injection molding of plastics, as this process is carried out in the following manner.

The process starts by forcing molten polymer into a mold designed to match the shape of the desired product. The polymer is then cooled and solidified to form the required part released from the mold. The custom injection-molded parts or products manufacturing process provides flexibility and can be used for medium production for about a few 100s to manufacture 1000s of identical molded components at a large scale. The process is widely favored for its economic production and helps industries like automotive, aerospace, and electronics to fabricate prototypes for functional testing and enhance the aesthetics of intended products or end-use parts.

Custom Plastic Injection Molding Materials

The types of plastics used in custom injection molding are diverse, with different melting points and peculiar characteristics that can be adjusted to suit a specific application. Here are some commonly employed thermoplastic materials for manufacturing high-quality injection molded parts.

Acrylonitrile Butadiene Styrene (ABS) 

ABS is a widely used thermoplastic material that offers flexibility, low density, and good impact strength. It is unsuitable for applications requiring chemical, electrical, or UV resistance. Because of its strength,

ABS injection molding is widely used in products such as children’s toys, household appliances, and car parts.

Low Density Polyethylene (LDPE) & High Density Polyethylene (HDPE)

These versatile thermoplastics provide high tensile and impact strength and resistance to moisture. HDPE injection molding is used in consumer and industrial products, while LDPE, which is softer, is also used in similar applications. Both materials are appreciated for their high degree of durability and ability to be bent.

Polycarbonate (PC) 

PC is a crystal clear, high-gloss matte, lightweight, and yet strong substitute for glass. It is highly resistant and has high impact and mechanical strength, PC injection molding parts aer good  ideal for use in applications like bulletproof glass.

Polyamide (Nylon) 

Nylon injection molding part is a popular thermoplastic known for its electrical properties, mechanical strength, heat, wear, and chemical resistance. Because of its durability and high functional performance, it is commonly used in the medical and automotive industries for injection molded mold parts.

High Impact Polystyrene (HIPS) 

HIPS is an inexpensive, impact-modified crystalline styrene-rubber copolymer widely used in producing disposable cutlery and toys. It is non-toxic, suitable for use in food-contact applications, and appreciated for its flexibility and low price.

Polypropylene (PP) 

PP injection molding part is a tough plastic with good chemical and stress resistance and high impact strength. Due to its high melting point, it is ideal for use in the food industry, where equipment must be durable and safe for use with food products.

These materials are chosen according to the application’s needs to provide the best performance and long life of custom injection-molded parts.

Tool Design and Engineering

In injection molding, the tool is the mold or die that forms the material into the intended part. It’s in fact a negative cavity that recreates the part’s shape with the correct dimensions to allow for the material to behave as desired during injection and cooling. In the production of custom molded plastic parts, it may be necessary to use one or several tools depending on the need. Although using more tools initially raises the cost a little, it greatly reduces the cost per piece in the long run, making it economical for mass production.

These tools are located in a mold base and are a single component of injection molding machines. Mold bases are costly, so we use insert tooling that can be fitted into existing polymer molding mold bases.

Our real engineers consider the details by analyzing DFM analysis to material, and technique selection when creating custom-molded plastic components, including tool design and process optimization. They incorporate the right manifold and runner systems, molding processes, and functionalities without extraneous features, thus cutting costs on your budget. The high-tech software helps uniformly transition from virtual technical 2D or 3D g-code to m-codes to accurate tooling in the tool room.
