Insert Molding vs. Overmolding – The Difference Between Insert Molding And Two-Shot Overmolding

Plastic injection molding may be used to merge two (or more) materials into a single component in a few ways. How can this benefit a product developer? Let’s look at the benefits of insert molding and overmolding in more detail.   What Exactly Is Insert Molding? Insert molding is the process of attaching one of the insert’s components to a pin or other retaining fixture within a plastic injection molding tool. When the mold is closed, thermoplasti......

The Best Ways Of Using Plastic Injection Mold Tools To Get The Perfect Surface Textures

  Surface textures on molding tools are significant for reasons other than aesthetics. Here are a few examples of topics to think about: Different textures will influence how moldable a part is. Some increase heat transfer between the tool wall and the resin, necessitating the use of alternative cooling solutions. Other texturing will cause the part to cling inside the mold until the draft angle is increased. Because heavily textured surfaces require more dwell......
