The thermoplastic injection molding process is a standard process that involves an aluminum mold and no heating or cooling lines pass through it, which means a longer cycle time. It allows our molds to monitor the filling pressure, appearance issues, and the basic quality of the parts.
The resin particles are put into a bucket, where they will eventually be melted, compressed, and injected into the runner system of the mold. The hot resin is injected into the mold cavity through the gate to form the part. The ejector pin facilitates the removal of the part from the mold, where the part falls into the loading bin. When the run is complete, the part (or initial sample run) will be boxed and delivered soon.
The following are its biggest advantages:
The mold injection process is highly efficient,Allows rapid production of large orders
High-pressure injection ensures that the molten material reaches every gap in the mold before it solidifies. This allows design engineers to incorporate complex geometries and complex elements into their designs.
Fast and efficient production ensures low cost of each part, while high production yields further economies of scale. Aluminum is a cost-effective, readily available material that can be used as a cost control tool.
The use of steel molds for injection molding can facilitate the mass production of millions of parts.
High tensile strength
Adding fillers to the liquid resin can enhance the tensile strength of injection molded parts.
Through proper treatment, the injection molded parts have a smooth finish when they come out of the mold, and no further refinement is required.

Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is the modification of the surface of the workpiece by using polishing tools and abrasive particles or other polishing media.
Pad printing is one of the special printing methods. It can print text, graphics and images on the surface of irregular shaped objects, and is now becoming an important special printing. For example, the text and patterns on the surface of mobile phones are printed in this way, and the surface printing of many electronic products such as computer keyboards, instruments, and meters are all done by pad printing.
