Co-Injection Molding
Co-injection molding(or sandwich molding) a process that creates a skin and core material arrangement in a molded part. The skin material is injected first into the mold cavity, and is immediately followed by a core material. As the skin material flows into the cavity, the material next to the cavity walls freezes and material flows down a center channel. When the core material enters it displaces the skin material in the center of the channel by pushing the skin ahead. As it flows ahead it continues to freeze on the walls producing the skin layer
Machine Based Co-Injection molding
The Co-Injection process requires two injection/processing units. The units generally inject material through a manifold located at the end […]
Injection moulding (or Injection Molding) is a manufacturing technique for making products from plastic resin. Injecting the molten plastic resin at high pressure into a mould, which is the inverse of the desired part shape, the part shape was created by designer using some CAD design software, The mould is made by a mould maker (or toolmaker) from metal material, usually either aluminum or steel, and precision-machined to form the features of the desired part by some high technical machine like CNC machine, EDM machine, lather machine grinding machine, wire-cutting machine etc, step by step to make final mould cavity base on exactly desired […]
