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.

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.

plastic moldPlastic injection mold is the primary process for manufacturing plastic parts. Although the tooling of plastic injection mold is expensive, the cost per part is very low. Today most of the companies are looking for mold manufacturer China suppliers to reduce the mold cost.

 Plastic injection mold is a popular and economical industrial process for manufacturing a wide range of plastic consumer products. These include knobs, washers, valves, pulleys, gears, power tools, bottle caps, toys, car panels, computer monitors, keyboards, furniture and so on. These items are mass-produced using molding machines of various sizes and various specific requirements.

The plastic injection mold process usually begins with an industrial designer or engineer who designs a product. This is followed up by the work of a toolmaker or mould maker who makes the mould to fit the design created. These moulds are metallic and usually made using either steel or aluminium. Using machines, they are made to acquire the exact shape desired by the design. Once this is done, the process of actually making the plastic follows.

Plastic injection mold involves taking plastic in the form of pellets or granules and heating this material until a melt is obtained. Then, the melt is forced into a split-die chamber/mold where it is allowed to “cool” into the desired shape. The mold is then opened and the part is ejected, at which time the cycle is repeated.

Choice of plastic type used in plastic mold depends on the kind of product being made, its requirements and the overall budget. Of the hundreds of available plastics, only a few are safe for consumer use. Some of the ones used in the plastic injection molding process include polystyrene, polycarbonate, polypropylene, polyethylene, polyamide, polyvinyl chloride, Teflon®, Delrin®, and acrylic.

Mainly, two materials that are involved in the plastic injection mold process are thermoplastics and thermosetting plastics. Examples of thermosetting plastics are Epoxy and Phenolic, while nylon and polyethylene are examples of thermoplastics. The plastics are liquefied and placed into the heated barrel where they are mixed and form a mold cavity, which is cooled down and hardened.

The machine used in the plastic injection mold process consists of reciprocating screws that are required to mix the granules. There is also a moveable pattern that is responsible for molding the plastic into the shape desired. All of this takes place in the clamping part.

Anyway, the production of plastic injection mold can be done through cheap tooling. Production can be made from bottle caps, containers, home appliances and plastic combs among many others. It is great to take advantage of the cheap tooling feature of this manufacturing technique.

The only things required would be the proper selection of materials based on the strength as well as overall function expected on the final part. Different parameters for production should also be taken into account.

Plastic molds is the only way you can do if you want to produce products in large volume. Using this method, you can avoid entailing pricey labour costs and the materials you need are relatively inexpensive. You can also minimize your scrap losses and there will be the development of high tolerance during the manufacturing.

Indeed, plastics are non-degradable and therefore not environment-friendly. However, the plastic injection mold process plays a positive role in reducing waste. Plastics used in the process can be reused as often as required.
