Vacuum injection mold, namely vacuum complex mode, also known as silicone compound mold, need to use the silicone mold. Both under the vacuum condition of pouring material of

defoaming, mixing, preheating, injection, and in the constant temperature box of 60 DEG to 80 DEG C for 2-3 hours of secondary curing process, silica gel complex mode of replica can

reach the strength and hardness of the ABS material, can also according to customer requirements color configuration with complex mode for replicated in the product development

process of plastic parts and small batch, more complex structure, uniform wall thickness, meet certain functional requirements of small batch sample copy of the production.

 Silicone compound die process:
1, production prototype: according to the customer provided by 3D drawings, CNC processing, SLA laser rapid prototyping or 3D printing production prototype.
2. The pouring silicone mold: prototyping and production of mold, fixed prototype, silica gel casting, 8 hours drying. The mould is opened to take out the prototype,

silicone mold fabrication is completed.
3, injection type: liquid gum material into the silicone mold, in the 60 to 70 degrees thermostatic box for 30-60 minutes of curing, demoulding and necessary in the 70

DEG to 80 DEG thermostat for 2-3 hours of secondary curing. Under normal circumstances, the use of silicone mold is 15-20 times.
