Silicone mold is widely used in the aerospaces, automotives, household appliances, toys and medical equipments,etc.It's applied in the new product development stage,and a small batch (20-30pcs) of samples' trial-manufacture.
The silicone mold is usually applied in the new product development stage, and a small batch (20-30pcs) of samples’ trial-manufacture. The silicone mold with good toughness can manufacture the parts with complex structures, fine patterns, no or even negative draft angle. The mould manufacturing period is short while the products’ quality is high .
We generally use the silicone rubber and the reactive polyurethane materials to make the silicone mold . It is a popular technology of rapid tooling manufacturing.
Advantages
The product materials includes like ABS, like PA, like PP, like PMMA, like PC, like rubber, etc.
① Short Manufacturing PeriodOnce you provide the 3D CAD files of the parts, we can produce the silicon rubber mold in a few days, with which we can cast the polyurethane plastic products. Compared with the manufacturing period of the traditional steel mold (30~90 days), it can shorten 90% of the time.
② Easy to DemouldWe usually need to set up the draft angle in the traditional metal mold, in order to demould easily after forming, especially for the parts with the deep grooves. Considering the silicone rubber has the good flexibility and elasticity, the parts with the complex structure, fine pattern, no draft angle or a deep groove, can be removed directly after casting, which doesn't have to be added the draft angle, so as to simplify the mold design as much as possible.
③ Good Replication PerformanceThe room temperature vulcanized silicone rubber has an excellent simulation and a very low shrinkage rate, which can well reproduce the fine features of the prototype parts and basically won't lose the parts’ dimensional accuracy. It is an excellent mould material.
