DSI molding

It is a molding technology that demonstrates its power into the realization of products featuring hollow structures or complex structures with built-in components.

DSI (Die Slide Injection Molding) is an injection molding method that enables quick and accurate molding of hollow bodies with complex internal structures.
It consists into a primary injection by which a semi-finished (divided) product is molded, then by molding a hollow body by sliding a hydraulic mechanism, and by a secondary injection for melting and joining. DSI technology eliminates problems such as uneven wall thickness or weak joining strength, which appear in conventional hollow-body molding methods.
