Solid Injection Molding Process

Definition:The process of injection and injection-transfer molding starts with efficient materialpreparation. To begin, the material strips are fed into a screw which, in turn, fills a barrel with theappropriate predetermined amount of rubber material.As with compression molding, transfermolding requires secondary raw material preparation into pre-forms. lt differs, however, in theolacement 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 iscompressed by the plunger and transferred through sprues into the cavity below then is softenedand cured by the heat and therefore forced to conform to the shape of the mold, as the moldcloses.

Scope of use:lf is widely used to produce products with complicated structure, high dimension accuracyand rubber-metal assembly, such as dust jacket, shock absorber support and bellows inautomobile industry, sanitary water tank, butterfly valve and other seals, all kinds of tee, elbowetc.
