 Injection Mold Tooling

As we know, if you want to produce a plastic product,you should make a injection mold tooling first.the mold is the key equipmemt for the shape.so let’s learn what the injection mold tooling is.

The injection molding process uses molds, typically made of steel or aluminum, as the custom tooling. The mold has many components, but can be split into two halves. Each half is attached inside the injection molding machine and the rear half is allowed to slide so that the mold can be opened and closed along the mold’s parting line. The two main components of the mold are the mold core and the mold cavity. When the mold is closed, the space between the mold core and the mold cavity forms the part cavity, that will be filled with molten plastic to create the desired part. Multiple-cavity molds are sometimes used, in which the two mold halves form several identical part cavities.

The mold core and mold cavity are each mounted to the mold base, which is then fixed to the platens inside the injection molding machine. The front half of the mold base includes a support plate, to which the mold cavity is attached, the sprue bushing, into which the material will flow from the nozzle, and a locating ring, in order to align the mold base with the nozzle. The rear half of the mold base includes the ejection system, to which the mold core is attached, and a support plate. When the clamping unit separates the mold halves, the ejector bar actuates the ejection system. The ejector bar pushes the ejector plate forward inside the ejector box, which in turn pushes the ejector pins into the molded part. The ejector pins push the solidified part out of the open mold cavity.

The mold life is different depends on the steel of inserts,if the inserts are made by pre-hard steel.the usual mold life is 300,000 shots.if the mold core and cavity inserts made by harden up steel,such as 1.2344,the mold life will reach 1,000,000 shots. The mold tooling is not cheaper because that the material(steel) is expensive,the process is very complicated and need rich experience staff.the price ranged from 1000-300,000USD

HEYA MOLD focuses on manufacturing all kinds of plastic moulds, like household moulds, kitchenware moulds, home appliance injection moulds, industry and agriculture plastic molds and so on. If you have any new mould projects, welcome to contact us by whatsapp or mob:8613867644770

 How to set your injection molding machine parameters? Injection Molding Machine Introduction Technology: Polycarbonate injection molding is an engineering technology that involves transforming plastic into useful and original products. Important process conditions for polycarbonate injection molding are temperature, pressure and corresponding individual time of action that affect plasticizing flow and cooling. Injection moulding machine setting – temperature control 1.  Barrel temperature : Temperature to be controlled during moulding process is barrel temperature, nozzle temperature and mold temperature. First two temperatures primarily affect plasticization and flow of plastic, while latter temperature primarily affects flow and cooling of plastic. Each plastic has a different flow temperature. Same plastic has different flow and decomposition temperatures due to different sources or grades. This is due to difference in average molecular weight and distr...

  What Is Plastic Injection Mold? A plastic injection tooling is a special type of manufacturing tool used for injection moulding. They are usually made of steel. Essentially, a plastic injection mold consists of a large cavity into which plastic is injected. This plastic flows around the core and the cavity, which have been built to create the proper size and shape of your component. Then, the plastic part solidifies on the mold, and is ejected from the mold once it’s hardened and solidified. Then, this process is repeated. A high-quality thermoplastic mold can be used to make millions of plastic components, and is a must-have if you are creating high-quality, high-volume injection-molded components. Plastic Injection Mold Terms If you are new to the world of injection moulding, there are some key terms you may want to know while working with an injection mold supplier. Injection mould This is a steel or aluminum mold that is used to injection mold plastic parts in a high-volume p...
