Foam injection molding / SF molding
If you want to create large and thick molded products, foam injection molding or SF molding is recommended. Since it is foam molding, it also allows for weight reduction.
Introduction to Foam Injection Molding and SF Molding. Foam injection molding and SF molding involve molding resin pellets with a chemical foaming agent. A skin layer is formed on the surface, while a foamed layer is created in the core section. Since the inner layer is foamed, it allows for weight reduction. Additionally, the injection pressure can be lowered compared to conventional injection molding, which minimizes deformation and sink marks despite the thick walls. **Benefits of Foam Injection Molding and SF Molding** - Capable of molding large and complex shapes. - Achieves weight reduction despite thick walls. - Reduces sink marks, warping, and distortion compared to conventional molded products. - Compatible with a wide range of thermoplastic resins. **Product Examples** - ATM covers. - Bases for analytical instruments (replacement from metal). - Top covers for analytical instruments (integration of components). - Cost reduction and weight reduction from metal covers. - Cost reduction and weight reduction from die-cast products.
