The procedure in the plastic mold design process

• Plastic parts or samples analysis

Study the plastic part shape, dimensions, tolerances and part cosmetic surfaces

• Confirm the injection machine model and relevant data

• Pattern parts and layout confirm

Consider part weight and injection machine capacity, precision of the part, how to deal with the undercut features etc

• Cavity and moldbase steel selected

• Decide the Parting lines on the plastic part

Don't affect the part appearance, be benefit to the part precision and mold fabrication, especially for the cavity fabrication

• Confirm the slider and lifter structure

• Moldbase and standard components selected

• Feed system design

• Air venting system design

• Eject system design

• The main components drawings draft

• Check the design drawings

• Leader sign on drawings to release drawings fabriction
