Choosing a China injection molding supplier: guidelines for success

Tips for Choosing a Reliable China Injection Molding Supplier

What Is Injection Molding

An injection molding process involves the injection of molten material into a steel injection mold and then allowing the material to cool, resulting in a solid shape and then ejected by an ejection system . It is possible to manufacture a wide range of objects via injection molding, including automobile parts, toys, and medical devices.

Step	Description
Melting	The heated barrel and rotating screw are fed with material from the hopper. The material is melted through heat, friction, and shear force caused by the screw’s rotation. It is then forced through a check valve to the front.
Injection	The screw is pushed forward by a hydraulic ram, moving it from the back end to the front. This action pushes the melted material forward for injection.
Cooling	The mold tool remains closed, allowing the injected plastic to cool and harden in the cavity. This stage typically takes the longest duration in the injection molding process.
Ejection	The screw is moved backward to prepare for the next molding cycle. The mold tool opens, and the hardened plastic part is ejected. The tool then closes, and the injection molding process repeats from step 1.

Material, usually metal or plastic, is melted inside the barrel at the beginning of the process. A high pressure injection is then used to inject the molten material into the mold via sprue,ruuner and gate. It is opened and ejected from the mold when the matter has cooled and solidified enough. The process of injection molding can be used to produce mass quantities of objects quickly and at a reasonable cost.

An overview of injection molding history

A history of injection molding can be traced back to the 1800s. Alexander Parkes invented a method for molding cellulose into objects in 1851, marking the beginning of injection molding. The first plastic injection molding machine was patented by John Wesley Hyatt in 1872.

As a result of this machine, plastic objects could be mass produced in large quantities in a short time. With the advent of mass-production of plastic products in the early 1900s, injection molding became increasingly popular. Medical devices, automotive parts, and electronics are among the types of products injection molded today.
