What are the processes in plastic processing or mold making? I would like to know all the technical names. Thank youI asked, "is that an ordinary plastic processing plant?". Or some manufacturers only extrusion injection molding. And what about the others?
Die forming methodMainly used for extrusion molding of thermoplastic plastics, can also be used for some thermosetting plastic extrusion. Products are continuous profiles, such as pipe, bar, wire, plate, film, wire and cable coating. In addition, it can be used for plastic mixing, plasticizing granulation, coloring, blending and so on.Extrusion molding machine is composed of extrusion device, and heating and cooling system. A screw type extruder (single screw and screw and plunger type) two types. The former is the continuous extrusion process, the latter is intermittent.The basic structure of Single Screw Extruder mainly includes transmission device, feeding device, cylinder, screw, head and die partsThe auxiliary equipment of extruder has three kinds of material pretreatment equipment (such as material conveying and drying), extrusion processing equipment (shaping, cooling, traction, cutting or roll) and production condition control equipment
5, injection molding and transfer molding. One of the main forming method is thermosetting plastics. It is feeding room, plastic pellets into the mould during heating, melting plastic under pressure through the pouring system of bottom mold transfer chamber fills the cavity, and then curing6, solid phase forming molding plastics in the melting temperature, the forming process has no obvious flow condition, for two times molding plastic sheet, such as vacuum molding, compression molding and air pressure molding, original for thin-walled parts molding, first used in the manufacture of thick wall parts.7, other molding calendering molding, casting molding, rotational molding, foam molding etc.6. extrusion. Extrusion is also called extrusion molding or extrusion. It is a method in which the material is continuously molded through the die in the flow state by heating and pressurizing
There are many plastic forming methods. Six main forming methods are listed below1, injection molding, also known as injection molding2, extrusion, also known as extrusion molding, is one of the main molding of thermoplastic3, hollow molding, also known as blow molding4, also called the compression molding compression molding. The upper and lower die is installed under the template in the press on, the plastic material directly into the cavity, the mold is closed, full of plastic cavity in the heat and pressure, setting after plastic parts.
