(2) Lack of material: reasonable product and mold design, also the reasonable setting of forming machine
(3) Burrs: according to the characteristics of plastic raw materials to choose a reasonable mold clearance and molding parameters.
(4) Damage: increase the draft angle and polish the mold parts.
(5). Burn mark: set reasonable molding parameters, improve the air vent of the mold.
(6) Cracking: reasonable product structure design, reduce the internal stress of the product. Choose a reasonable gate and runner design (location and size) to minimize the impact of the bond line on the product.
(7) Discoloration: design the product with a reasonable structure and increase the holding time and molding pressure.

8. What is the key point to design electrical connector molds?

The design of electronic connector molds not only takes into account functional factors, but also the manufacturability of the injection molding. Too thick or too thin or uneven thickness is not suitable, too thick is serious shrinkage, too thin is not easy to fill the mold, the uneven thickness is unbalanced flow wave front of liquid plastic filling and easy to cause cooling warpage. Mold design engineers need to improve the mouldability based on experience and confirm with the customer whether the structural strength still meets the functional requirements before carrying out mold flow analysis and mold opening actions.
