Why Choose Us 


1. Our Chief engineer graduated in 1991 from Hubei Polytechnic University Molding major and started work for mold design since 1991 for plastic injection molding, especially good at over-molding. And since 2002 to start to design LSR injection molding. Until 2016, he has designed 5086 sets plastic and silicone injection molds.

2. We design and produce molds for PIC, TUPPERWARE, HONEYWELL and HUAWEI.

3. We have 15 years experience in LSR over-molding, PIC’s projects almost all are over-molding. We have enough experience in how to stick LSR with other material and how to make the mold precise enough.




1. Q:

What kind of material can use with LSR co-molding and how their performance?



     --Metal: stick well, and temperature resistance also well.


     -- Nylon: stick is the best of these 3 kinds of material, but for colors, not so good in control.


     -- High temperature resist PC: both stick and temperature resistance are not as good as metal and nylon.


2. Q:

Why for over-molding molds can not build too many cavities or too large?



For over-molding molds, the precise request are very high, if build too large or too many cavities, it would be very hard to adjust balance when doing mass production.
