Injection Moulding, along with extrusion ranks as one of the prime processes for producing plastics articles. It is a fast process and is used to produce large numbers of identical items from high precision engineering components to disposable consumer goods.
A mold is a hollow metal block into which molten plastic is injected to from a certain fixed shape. … Molten plastic flows into a mold through a sprue and fills cavities by way of runners and gates.
EVA is a thermoplastic polymer, so it can be used in injection molding, extrusion, blow molding, calendering, rotational vacuum thermoforming, foaming, coating, heat sealing, welding and other processing molding processes.
In terms of shoe materials, EVA foaming process generally has three processes: traditional flat large foaming, small in-mold foaming and injection cross-linking foaming. Among them, molded foaming and injection cross-linking foaming are more used. In recent years, with the development of supercritical foaming technology, EVA materials can also realize the foaming application of this technology.
Injection cross-linked foaming has now become the mainstream process for preparing EVA shoe midsoles by large shoe material processing factories. The process is to mix EVA, modifiers, additives, etc. at high speed, extrude and pelletize, and then perform injection molding. Only half the size of the finished midsole.
The high-temperature mold needs to stand for a period of time, otherwise, the EVA midsole will pop out when the mold is opened. Because the mold is much smaller than the actual midsole, the midsole will expand rapidly when it is released from the mold. After the injection molded midsole expands to a larger size, it may shrink during the subsequent cooling process. Therefore, the expansion and contraction process of the injection molding method is more complicated than the compression molding method.
