the mold industry lays great emphasis on efficiency. Sometime, considering the credit therein, even when business negotiation between the manufacturing and the customers is still under way, […]
the BOM table takes mold products as the unit, namely, mold products recorded in the same BOM table are of the same serial No, and are distinguished by material No, […]
Moldmakers are always juggling the various complexities in a mold build. If the mold is relatively flat, the balls (tennis) are relatively easy to juggle. As the mold becomes more complex or deeper, the weight and size of the different balls changes (add a bowling ball and a ping pong ball). At the end of [...]
Nylons are generally tough and strong and boast high oil resistance and chemical resistance. They can be in stable use whether under high temperature or low temperature and hence possess excellent qualification for being used as engineering plastic. […]
For years we have been hearing about the virtues of aluminum molds for injection parts, and First-rate mold company’s Mold Builders has built its fair share—mostly for special-purpose applications that did not require many actions. For smaller molds using specialty aluminum has its benefits; and, if cycle times are critical, you can justify the high [...]
In the injection molding world, everybody has an opinion about how molds should be gated – how many should be used; where should they be located; and, what size and shape should they be? Much of what is actually implemented into mold designs comes from experience, whether it is from the moldmaker, molder or material [...]
“How can we mold more parts on the same equipment in less time and lower our costs?” is a standard question whose common answers include reduce cycle time and/or improve mold yield efficiency. Surface treatments have been part of this solution and in the last 10 years a new family of coatings—DLC (diamond like carbon)—has [...]
the material is selected for the part molding area according to the surface roughness of the plastic part and the expected number of injection cycles. […]
you know, some material are difficult to mold, when we have to choose one of them to mold our product, do you know what to do? […]
but submarine gate has it’s special requirement in injection molding, it requires a larger flexibility to accommodate elastic deformation of the gate slug at ejection. […]
