Often overlooked is the key to a good mould instead, each mold demanders is important to note that in the development of plastic mold, for its way into the water must be strict requirements.
Because into the pouring way directly related to the quality of plastic products, such as weld mark, underfill, miniature and bending deformation and so on.
For plastic mould into the water the way, if the product is simple or mold development, there are similar products before we can draw experience, consider into the water the position and form of plastic mold.
And on the need for more complex plastic products, mold flow analysis to determine its into the water the way.
Seems to increase the fees for the piece, in fact is swept away after a big hidden trouble.
sometimes, even if the surface of the plastic products is flat, as well as very precise plastic mould processing, but also can appear products bending deformation or surface uneven phenomenon. There may be the reason why big products into the water the way is not reasonable. Especially for some plastic injection difficulties, such as PPS, such as PC + ABS. Due to the injection molding, plastic through the gate has the effect of a force, the force effect directly to the plastic products, so as to cause plastic deformation. So we first need to consider from the Angle of the way into the water injection balance, often by more into the water the way. Such as PPS plastic pump impeller mould, remove the plane. For the product deformation problem, on the one hand, improve the product structure, on the other hand can by changing the gate, avoid gate directly on the product.
plastic mould into the water the way can be solved through experience and good mold flow analysis. Of course, we at the time of default into the pouring way, want to consider the possibility of repair and modify, a set of mold must be strict control, to every detail into the water the way like eating system, things go into the belly to shouldn't place, that people will be sick!
