Gas-assisted injection molding process is much complicated,the process parameters have multiplied. In this paper, a product with typical character of gas-assisted injection molded part is employed as the object of study. With the mould of gas-assisted injection molding and MPI/3D GAS in Moldflow software,the influence rule of the 6 important process parameters on gas penetration length in gas-a...

Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. When the material is in contact with the mold wall surface, one has three choices: i no slip which implies that thematerial sticks to the surface ii partial slip, and iii complete slip 1–5 . Navier 6 in 1827 first proposed a partial slip condition for rough surfaces, rel...

The "RapidTool" Short Run (SR) Tooling Process using the Copper Polyamide material provides a route to mold inserts for injection molding made directly in the Selective Laser Sintering machine. The STL files for the mold inserts are shelled and conformal cooling lines and ejector pin guides are added before SLS processing. Sintering of the material in the SLS machine provides quick metal/plasti...

1) Uniform Wall Thickness, Coring & Mass Reduction since injection molding is employed as the shape forming process step, part designs can avoid the limitations of traditional metalworking processes. For example, machining involves the removal of material from a solid shape to get to the desired final component design. As a result, design engineers are limited to design decisions that can be re...
