How to Select Mould Steel for your tool? There are many kind of steel, for long runs production, a durable mold is required, the tool steel must be selected properly, for small volume production, steel selection can be as economic as possible as long as it meet the requirement of production demands. How to
Why you need mold for customizing your plastic producs? what's mold? and why do you need it? Mold is a kind of tool that form the molten plastic raw materials into designed shape and measurement, finishing, parts produced by utilizing mold is very common to see around your daily life, your phone case, most
How to be a good Injection Mold Tool Designer? To ask about "Best Injection Mold Tool Designer" you must quantify what specific type(s) of tooling you are most interested in. Since this thread is under Injection Molds, I would add that the typical tool designers are experienced with certain industries and thus are familiar
How to avoid sink mark while injection molding plastic products? Intuitionally part thickness uniformity is often attributed to sink marks, but most researchers have concluded that such conception is very vague or subjective! Instead it is part thickness distribution with respect to injection point (gate) towards the extreme point on the melt flow path
Estimated ejection force formula From the book "Injection Mold Design Engineering - David O. Kazmer", Estimated ejection force is calculated by using formula: Feject = µfric . cos (draft) . E . Ctermoexpand . (Tsolid - Tejection) . Aefect . The same could be used for slide calculation force. From this you can see
INFLUENCE OF INJECTION MOLDING PROCESS CONDITIONS ON PLASTIC PRODUCTS Plastic material The complexity of the properties of plastic materials determines the complexity of the injection molding process. And the performance of plastic materials varies greatly because of different varieties, brands, manufacturers, and even batches. Different performance parameters may lead to completely different molding results.
