Design principle of ejection system Product ejection is the last step of the injection process, the ejection quality will directly affect the quality of the product, and design should follow the principles. (1) The principle of equilibrium layout: ejector pins…
Local thick wall thickness, wrong position of gates and cooling layout would lead to sink marks, trapped air, deformation and burns on the injection parts, the following will analyze some factors: Wall Thickness: The wall thickness should keep same to…
In the injection molding, short-filling, trapped air burns, high internal stress, flow marks and weld lines and so on could be often seen. To solve those problems, the first consideration is the process setting, and the gate design also plays…
False Injection molding machine operation will cause poor quality, rejected plastic parts, lessen machine life and the damaged screw. The following lists a detailed and comprehensive description of the standard process to avoid misbehavior. A: Operational requirements Before starting to…
Prototype plastic components are generally employed to confirm the functionality of a designed component. The verification needs vary from size to loading, which is based on the end-use needs for the components. Components designed for engineering applications probably demand many…
Mould Finish Mould Finishing-Nearly all cavity and punch forms require a Finish to be applied to them. This may be a Polished finish, a photo-etched finish or a plated finish. However, for some technical Components the surface finish is not…
Plastic bumper mold It is a development trend in the automotive industry for plastic bumper to replace the metal bumper.Plastic bumper mold design currently mainly has two structures: (1) exterior P/L (2)interior P first structure is relatively simple for mold…
