Gas injection, inject high-pressure inert gas such as nitrogen into the core of fusant and the gas enveloped by plastic fusant shall move forward along a direction with minimum resistance and meanwhile push the flowing front of fusant to move further forward unitl the mold cavity is fully filled. […]
fusant injection, the plastic fusant is quantitatively injected into the mold cavity. In this stage, it is very similar with traditional injection molding. […]
but how to design a suitable nozzle, different product has different requirement, so you can see different dimension of gate mark on different product. […]
let’s try to describe hot runner system, that means between the major running channel of mold and the gate of the molded product, […]
Of course, after understanding product well, in mold designer side, he or she also allow to suggest changes, especially in the areas of fragile mold cores or thin ribs, not only to make the mold easier to build but also to extend the life of the mold and to improve its serviceability.
As a professional mold designer, it is very important to understand product well. For example, where and how is the product to be used? Required fits with other products, finish, strength, location of gate, ejector, etc.
When any product contains even small portions of degraded material, it must be discarded, not only because of poor appearance of the product but physical properties may have been lost and the product will not perform as expected.
Compare Part for ChangesWhen the design model changes, you need to know what changed. Look for tools that make it easy to detect what is different in a part; […]
Power to Handle Complex GeometryFor the software to be usable for plastic part design, it must be powerful enough to handle the complex geometry. The system must possess round, draft and complex surfacing capabilities. […]
The first to enter the market and still the most common are thermally operated. […]
