Plastic products structure-plastic products structure importance-Sino
Sino Mould is a famous plastic mould manufacturer all over the world. After years of working experience in injection mold industry, Sino concluded that a good injection mold can’t do without a good plastic products structure. What’s more, we need controller it from the injection mold design.
When make product design, the designer should try his best to avoid unnecessary undercut, and avoid mold core pulling, thereby to simplify the mold structure.
Suitable thickness and everage of plastic products will be better. and uniform wall thickness changes in wall thickness is too small will cause the flow resistance is too large, missing gum occurs, resulting in waste of raw material wall thickness over the General Assembly and has shrunk severely. Where the wall thickness of mutated, cause stress concentration, away deformed, so product design should be consistent as far as possible the wall thickness or wall thickness change to be smooth.
Some local plastic parts should be designed rounded to avoid the problem of mold clearance angle, and also increases the robustness of the mold. Meanwhile, the other side in some places, such as sub-surface or core and cavity with the Department of plastic parts are not designed to be rounded, otherwise it will difficult parting, mold complicated.
Then, the plastic products structure dimension must be completely. Lack of size will make mold designer at a loss, while the extra dimensions may cause critical dimensions of control, resulting in increased excessively tight tolerances increase the difficulty of mold design and tooling costs, and therefore the size of the development of tolerance should be carefully analyzed.
