How many types of molds? Please help me out!
The mold can be divided into metal mould and non-metallic mould according to the material that is formed. The metal mould is divided into: casting mould (non-ferrous metal casting, steel casting) and forging die etc. Non-metallic mold is also divided into: plastic mould and inorganic non-metallic mould. And according to the material of the mould itself, the mold can be divided into: sand mold, metal mould, vacuum mold, paraffin mold and so on. With the rapid development of polymer plastics, plastic mould is closely related to people's life. Plastic mould can be divided into: injection molding mold, extrusion molding mold, gas auxiliary molding mould and so on.
The classified method of plastic mold profile at 11:30 on Friday November 7, 2008 mold is one of the important technology and equipment, modern industry is an integral part of many industrial products production. After China's accession to the WTO, the ability to attract foreign investment increased year by year, the increasingly prominent position, to become the world manufacturing factory of all kinds of industrial products mold imports more and more. The type of mold is usually carried out in accordance with the process of processing object and different classification, from the industry point of view to see the distinction between the main plastic mold, rubber mold, metal cold punching mold, metal cold extrusion die and hot extrusion die, metal drawing dies, powder metallurgy mold, metal die-casting mold, metal precision casting die mold, glass, glass fiber reinforced plastic mould and so on. Although there are many kinds of molds, the main items in the tax classification are the items of the tax items 84.80 and 82.07. The following is a description of how different types of molds used in the most common plastic processing are described. Plastic forming method of the most common general divided into two categories: the melt molding and solid phase is melt molding plastic heat to above the melting point, make the molten forming way, belongs to the molding methods of molding process mainly include injection molding, molding (shrinkage) molding, extrusion molding, etc; Solid-phase molding refers to a type of forming method in which plastic is kept solid under molten temperature
Die, forging die, stamping die, aluminum casting (casting) using the block, wax mold, plastic mold, metal mould, plastic forming with modeling profile (profile), pressure molding die, glass blowing blowing mould,... This is for use. Cold/hot mold; This is divided by temperature. There is steel die, aluminum die, hard alloy mold; There are wood, sand and wax models; With a plastic mould; This is part of the material that makes the mold. There is a one-off model, multiple sex dies; Permanent model This is from the service life. There are mechanical moulds, space moulds, plastic moulds, building dies, and... This is part of the industry. There can be other calls, there is no uniform rule.
