Injection molding is an important process to produce plastic articles. This advanced method is used to manufacture everything from disposable consumer goods to engineering components with high precision. Here is the list of materials used to produce parts from thermosetting and thermoplastics-
- Nylon PA
- Polypropylene PP
- Styrene ABS
- Polycarbonate PC
The wheelie bins and car bumpers are manufactured using this technique. Different sectors are using this method to produce outstanding products. The best thing of using this technique is that it offers great flexibility and shape to the molded objects. It has successfully replaced the traditional methods of producing objects.
This technique works in a unique manner. The process is broadly divide into four categories-
- The clamping where the material is fed into mold
- Injection when the shot is injected to the machine
- Cooling where the plastic cools down
- At the time of Ejection, part is ejected from the mold

Granules are taken in a heater barrel and melted with the heater bands. Then the plastic is injected in the mold cavity through nozzle till it hardens. Further the tool is mounted over a platen. Once the resultant solidifies, it is ejected with the help of ejector pins. The product is finally designed by experienced and qualified engineer. Later, the mold makers are asked to mold intermediate products as per the specific requirements. They use steel, aluminum or even metal to mold items.
The experts have to be really careful while performing the tasks. They ensure that the items are properly designed to make injection molded task simpler. They consider several things before proceeding ahead like-
- The shape and features they wish to achieve
- Material to be used
- Important properties of the molding machine
The high pressure injections of the raw materials are used to shape the polymer as per the requirement. You could use the molds of single or multiple cavities according to the demand. In case of the multiple cavity molds, you could either use the parts of identical forms or unique forms. The unique shapes are used to create different geometries at the same time.
Before proceeding ahead with this technique, you must learn its advantages. It is available at low prices in many countries. It is a quick, reliable service and hassle free.
There are many companies that specialize in plastic injection molds China using this technique. You must make a list of popular and reputed companies in your city. Go through their testimonials section and the ratings. You could Shortlist the company that has 4.5 or 5 star ratings. Besides this it is important to check the history of these companies.
