Surface Finishing: Sanding, Texture and Conductive Painting
Quantity & Lead Time: 25 Units, 25 Days

The extremely competitive mold price and fast delivery of our RIM process got this big enclosure low volume manufactured cheaply and quickly. The finished enclosures had to not only perform as intended, but also look as close as possible to the reference sample provided by customer.
RIM ToolingOur RIM mold cost just a fraction of its relative steel mold used for mass production, manufacturing time usually 2 weeks instead of several months.
RIM big parts.jpgThe reaction injection molded part prior to surface finishing. Good flexibility and high durability were the great features of our RIM parts.
RIM large parts.jpgCooling time of parts in mold usually took half hour since the solidifying reaction generated some heat which led to a temporarily high temperature.
RIM PartsThe deburred and sanded parts for consistent texture painting on external surface and conductive painting for EMI shielding on internal surface.

Our RIM process could bring tremendous cost and time saving for Low Volume Manufacturing big parts without compromise of quality.
