Handle houring double color 2K injection molding

FEATURES

• Handle houring double color 2K injection molding
  

  Secondary over-injection molding process:

  The secondary over-injection molding process is to inject a layer of plastic materials of different colors on the basis of the handle shell to create a Double color effect.

  The main steps of the secondary overmolding process include:

  Prepare plastic pellets: Prepare plastic pellets of two different colors.

  Injection molding: First, the first color of plastic is injected into the mold to form the base layer of the handle shell. A second color of plastic is then injected into the mold, covering the base layer to create a two-tone effect.

  Cooling and solidification: After the plastic injection is complete, the mold will cool and solidify for a period of time.

  Take out the product: Finally, open the mold and take out the formed Double color handle shell.
