What Is Injection Molding?
The injection molding process involves injecting molten plastic into a mold tool, then ejecting the solidified part. injection molding is the most cost-effective way to make a plastic part at scale.
PPS Industrial is specialized in plastic injection mold tooling and injection molding service decades experience. we offer a complete manufacturing solution that covers every aspect of raw material verification, tool making, part fabrication, finishing, and final inspection.

Injection Moulding reduces the amount of time that it takes to make the parts. not only increase productivity also keep costs low.
|
Uniform thickness are no structural deficiencies that could cause problems down the line. the tight tolerances of molds make sure that parts meet industry standards. |
Allows for greater design freedom than traditional manufacturing methods, making formerly impossible designs a reality.

Surface Finishes of Injection Molding
The process includes various steps, from injection mold tooling to entire plastic injection molding. Surface finishes of molds are processes typically carried out during production. At our company, we perform the specific surface treatment after the injection molding process according to customer requirements

Injection Molding Blogs
We are exceptionally capable to provide reliable and efficient injection molding services. Our state of the art machinery and seasoned team makes us a leading player in this field. Our injection molding capabilities are plastic molding, insert molding, over molding, and Two-shot molding.
It depends on the part design, the more features on the part will make more time building an injection mould, Usually 4 to 8 weeks. We will do our best to finish the mould production within our customer demand.
Each material has a different specific application, performance, molding properties, mechanical properties, and cost of the resin. If you are not sure which material should be used, pls feel free to ask us.
Our customer! Mold belongs to our customer property, it will only be used to produce plastic parts for you, and handled by you.
Yes, if you are not satisfied with T1 samples and want to change some structures, just provide a newly changed CAD file, then we will check again, and tell you some necessary mold modification cost.
Yes, it is called a family mold. If these parts are the same color, material, it is a good way to reduce the mold cost and make these parts in one mold.
