The Design and Development Department is the creative and technical heart of the plant: transforming customer ideas or market requirements into a plastic product that can be produced efficiently and with high quality. Responsibilities include product design, manufacturability analysis, prototyping, material and performance testing, and tooling and mold preparation for production.

 
Clear, practical steps

Receiving specifications / Market research — Understanding functionality, constraints, and cost.

Sketches & concept — Hand or quick drawings.

CAD design — 3D model building (SolidWorks/Creo/AutoCAD).

Moldflow simulation and design (flow analysis) — Analyzing the resin flow to reduce defects (warpage, weld lines) and optimize gate and cooling channel placement.
Autodesk

Rapid Prototyping — 3D printing or CNC cutting to test form and function before the final mold. caplugs.com Test mold and production sample printing — small injection molding trials (pilot runs).
