Rubber Transfer Molding also called Transfer-injection Moulding, which molded process by hydraulic press (rubber compression molding machines), and just designs of mold structure is a little different from rubber compression molding. Transfer molding is ideal supplementary mold for compression molding machines in aim to save tooling cost.
Rubber Transfer Molding is designed for over-molded (metal, plastic) components, tighter control of dimensional tolerance, cylinder shaped products (like nozzles, thin bellows or tubing), medium-precision or complicated structure rubber components.
Compared with Compression Molding, Transfer Molding also needs preformed raw material to be prepared. The preformed silicone rubber material is placed to a pot between the top plate and a plunger. After mold closes, plunger compresses the material and transfer it through sprues into the cavities.
As with compression molding, transfer molding requires secondary raw material preparation into pre-forms. It differs, however, in the placement of these pre-forms into a "pot" located between the top plate and a plunger. When the pre-forms are placed into the pot, the mold is then closed and the material is compressed by the plunger and transferred through sprues into the cavity below.
Reduce Materials Waste: Please choose rubber injection molding with cold runner system or liquid silicon rubber injection molding (LIM Mold) for LSR materials production.
