plastic injection machine

Plastic processing machinery is a mechanical equipment for processing plastic products, mainly processing plastic products, plastic machinery processing process is: 1, plastic ingredients, plastic processing raw materials, in addition to polymer, in order to improve the performance of molding process and products or to reduce the cost of products, various plastics additives (such as stabilizers, plasticizers, colorants, lubricants, reinforcements and fillers, etc.) should be added. Additive and polymer by mixing, evenly dispersed into powder, also known as dry mixture. Sometimes the powder has to be molded into pellets. Such powders and pellets are collectively referred to as batching or moulding materials. 2, plastic molding, the key link of plastic processing. A product or blank made of various forms of plastics (powder, granular material, solution or dispersion) in a desired shape. There are as many as zero ways to form it. The choice depends on the type of plastic (thermoplastic or thermosetting) , the initial form, and the shape and size of the product. Extrusion, injection molding, calendering, blow molding and thermal molding are common methods for processing Thermoplastic. Molding, transfer molding and injection molding are commonly used for processing thermosetting polymer. Laminating, molding, and thermoforming are the processes by which plastics are molded on a flat surface. All the above plastics processing methods can be used for rubber processing. In addition, there are liquid monomer or polymer as raw materials such as casting. Among these methods, extrusion and injection molding are the most commonly used and the most basic molding methods
