What is gas assisted injection molding process? Gas assist molding is a low-pressure plastic injection molding process where pressurized nitrogen gas is injected into the mold, pushing the plastic into the mold extremities, while hollowing out thicker sections in the part.  What are the advantages of gas assisted injection molding? Advantages. This process forms a hollow, plastic injection mo...

2K injection molding 2K injection molding: product injection molding with 2 different  plastic materials or 2 colours : efficient and economical.  Where the K come from? The K in ‘multi-K’ comes from the German word for component – “komponente”. So, if you see a reference to 2K or 3K moulding, it simply means that two or three different materials, or components, are used in the moul...

Undercut In Plastic Injection Molded Part Design  Undercuts are those features in an injection-molded part that prevent its ejection from the mold. Draft Angle In Plastic Injection Molded Part Design  A draft angle refers to that slant applied to the sides of most features of injection molded parts. Positioning of the injection angles is such that they run towards the direction of the mo...

Shutoff in Plastic Injection Mould  Shut-Off angle is applied for prevent the mold parts (Core and Cavity) from crashing into one another if there is any slight misalignment upon mold parts closing. Shut-OFF angle also prevent galling that would occur if vertical metal faces were rubbing against each other. Eg.  Note: A draft angle exists for purposes of part release, while a shutoff exi...
