How to achieve a good injection mold design?

blog aco mold

Mold design is a start of success molding processing; an optimum mold design is aim for the best molding performance.
Mold design
To achieve a good mold design, you need to take elements into consideration as below:

  • The most optimum mold cavities layout.
  • Proper mold base size and guiding way.
  • Provide reasonable injection mold flow and filling performance.
  • Use reasonable shrinkage factors ,especially parts in long length).
  • Study the part design in 2D, the tolerance required determine the way you design and machine it greatly.
  • Adequate cooling layout.
  • Proper ejection distance, de-molding way.
  • Minimum injection molding cycle time and as less as possible secondary works such as de-gating, drilling.
  • Appropriate gating location, welding line position accepted by the customer.
  • Minimum clamp force requirements, as less as possible injection pressure requirements. (the injection molding machine required smaller, the injection molding cost lower)
  • Adequate venting as well as reliable sealing to avoid flash occurs.
  • Minimum scrap rate (most important factor to influence the real cost of injection molding process).
  • Proper selected steel and heat treatment, just fit the demands of the customer ( otherwise it would be called “over-designed”).
  • Watch out the particular features such as sliders, lifters, make sure all the mechanisms designed perform well
  • Study the part design in 2D, the tolerance required determine the way you design and machine it greatly
  • Minimum clamp force requirements, as less as possible injection pressure requirements. (the injection molding machine required smaller, the injection molding cost lower).

A lot of defects occur frequently can be minimized by good mold design:

  • Flash
  • Sink mark
  • Surface defects
  • Short-shot
  • Unbalance filling
  • Many other common defects

A good mold design can reduce the manufacturing cost as well as shorten the delivery time, it also increases mold quality, productivity and provides best performance stability.
