Making method of suction nozzle
Injection molding is a method of making plastic products.Molten plastic is injected into the mold of plastic products through pressure, and various plastic parts are obtained through cooling molding.Suitable for large quantities and high precision products.The price of the mold is not specific.
Most nozzles on vertical bags are "plastic suction nozzle " that are environmentally safe.
In addition to polymers, the raw materials used in plastics processing are usually supplemented with various plastic additives (such as stabilizers, plasticizers, colorants, lubricants, reinforcers and fillers) to improve the molding process and the use of the product.Performance.The additive and polymer are mixed and evenly dispersed in a powder, also known as a dry masterbatch.Sometimes it is necessary to process the master material into pellets by chewing.The master batch and the master batch pellets are collectively referred to as batch or molded plastics.
Molding is a key part of plastic processing.The molding of various forms of plastics (masterbatch, pellet masterbatch, solution or dispersion) into the desired shape of the article or stock.The choice depends on the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product.Common processing methods for thermoplastics include extrusion, injection molding, rolling, blow molding and thermoforming.Thermosetting plastics are usually molded, transferred and injected.Laminated, molded and hot molded plastics are formed on flat surfaces.
