Toolmaking vs. Mold Design: What impacts part quality?

Toolmaking and mold design / tool design decisions are a major factor in the stability of plastic injection molding. Small changes in gating, cooling, or material flow can impact dimensional accuracy and surface finish.

Key considerations

• Cooling layout and thermal balance
• Material flow and gate placement
• Steel choice and wear resistance
• Validation and process window definition

Why it matters

Well-designed tools reduce scrap rates and improve repeatability in plastic parts manufacturing. They also shorten ramp-up time in injection molding services.
