Automobile Plastic Parts

During this initial phase, Design Engineers, Tooling Engineers, Materials Engineers, Manufacturing Engineers, Quality Engineers, and Lab Technicians work together to determine product specifications, tooling component capabilities, tooling materials, operating limitations, and any required product enhancements and improvements. The team specifically looked for any potential issues with part geometry or tolerances that could result in poor steel condition or require special tool features such as lifters, slides and threading/unthreading. The physical and chemical properties of the selected resins are also evaluated in order to select suitable mold steels and review mold cooling. In addition to determining the proper vent location, a mold flow evaluation is performed to determine the optimal gate type and gate location.

The manufacturability review includes the validation of standard plastic design practices and the incorporation of tooling details to create the most robust design possible. Tool specifications and tool provenance are finalized and purchased component sources are qualified. A comprehensive Process Failure Mode Effects Analysis (PFMEA) was also completed.
