Having your own branded items sets you apart from the competition. It makes your business more [...]
Both the shrink mark and shrinkage porosity are defects of injection products due to the molding shrinkage at thick walls where no sufficient follow-up compensation is made. During the injection process, the surface layer of products often condenses first, followed by the center layer, which will cause sinking on the surface of parts with thick [...]
As a professional engineer, he(she) really knew how to choose the right materials to build a strong house. The right plastics make your products light-weight, easier to use and yet possess increased structural strength. If we use engineering grade materials in our products, Plastic parts can be stronger than metal parts. In structural design of your [...]
Every people who works in manufacturing industry must know manufacturing cycle meaning– Eliminating secondary operation further reduces costs. […]
maybe you have some products at hand, they consist of some plastic parts, I think you might be interested in how to assembly and disassembly, when we put them together, it snaps into a groove or a slot in the mating part, […]
Time and cost are becoming more and more important factors in the development of new products. It is therefore extremely important for the injection molding industry to produce prototypes that can go into production as quickly as possible. […]
Polishing may achieve special optical properties in a product. When enlight beams pass through the product wall( compact discs, mirrors, etc.), any major unevenness or waviness will distort the light and result in poor performance of the product.
Polishing may enhance the appearance of the product. This is the most common requirement in plastic molding. It should be noted, however, […]
Polishing may facilitate ejection. This applies generally to the finish of the core, including side cores, in cases where the product has projections produced by deep recesses in the cavity or where there is little draft angle specified, the cavity must also be free of any roughness that prevent easy ejection.
Polishing may prevent stress risers in a product. Any sharp indent or corner in hardened mold steel, usually created during grinding, will increase the risk of breakage caused by stress concentration. Such corners must be polished to remove the shape “ gouges”.
