Precision plastic injection mould for consumer electronic parts

Precision plastic injection mould for consumer electronic parts

Short Description:

Suntime Mould has made several same plastic moulds for this kind of precision injection tools for mobile connector. This project has short lead time and high precision requirement. The parts need to do heat treatment after molding. It is multi-cavity (8 cavity) high temperature mould, the mould temperature reach to 120 degree, and plastic injection molding cycle time is 9 seconds. Moulds stay in Suntime for injection moulding production, over 100,000 parts were needed each day.  We are not only making high quality precision plastic injection mould, but also be a reliable manufacturer of custom plastic injection molding service in China for you.

We have made many tools for this customer. Our designers work very effective, for DFM, it can be finished within 1~2 days, 2D layout within 2~4 days, and 3D within 3~5 days depending on mold complexity. When time is very urgent, we normally make 3D drawing directly after DFM, but of course, it must be based on customers' approval.
