Injection molding is a method of manufacturing plastic products. The molten plastic is injected into the plastic product mold by pressure, the cooling molding is used to obtain various plastic parts. It is suitable for large-volume high-precision products. The price of the mold depends on the specific situation. Wait.

The raw materials used in plastic processing, in addition to polymers, generally need to add various plastic additives (such as stabilizers, plasticizers, colorants, lubricants, reinforcing agents fillers, etc.) to improve the molding process the use of products performance. Additives polymers are mixed uniformly dispersed into powder, also known as dry masterbatch. Sometimes the masterbatch needs to be plasticized processed into pellets. This masterbatch masterbatch particles are collectively referred to as batch materials molding compounds.

Molding is a key link in plastic processing. Various forms of plastic (masterbatch, granular masterbatch, solution dispersion) are made into products blanks of desired shape. Its choice is mainly determined by the type of plastic (thermoplastic thermosetting), the initial form, the shape size of the product. The commonly used methods for processing thermoplastics include extrusion, injection molding, calendering, blow molding thermoforming. The processing of thermosetting plastics generally uses compression molding, transfer molding, injection molding. Laminating, molding, thermoforming are forming plastics on a flat surface.

"Plastic nozzles" have many problems in actual production, but there are mainly two outstanding problems: one is leakage air leakage when the goods are contained; the other is the unevenness of the bag the bottom seal during the bag making process. symmetry. Therefore, how to make a good choice of materials adopt appropriate process operation methods plays a decisive role in improving the overall quality of the self-supporting bag.
