Several kinds of common metal clothing products processing
The coat hooks of metal forming process is made by the synthetic resin factory in process of polymer made the final metal products.
Processing methods (
Often referred to as metal clothes a processing)
Including the molding (
, extrusion (
, injection (
, blow molding (
, rolling, etc.
Compression mould pressing or forming technology, also known as compression is mainly used for phenolic resin, urea formaldehyde resin, unsaturated polyester resin and other thermoset molding metal clothes.
Extrusion is also called the extrusion molding, is the use of squeeze molding machine,
Continuous heating of resin through the mould, the method of the shape of the products required.
Sometimes do in extruded thermosetting molding metal clothes, and can be used for the forming of foam metal clothes.
Extrusion can be extrusion products of various shapes, the advantages of high production efficiency, can be automated, continuous production.
Defect is thermosetting metal coat hooks cannot be widely adopted processing, easy to produce deviation in dimension.
Injection molding is also called injection molding.
Injection molding is the use of injection molding machine,
Or the injection machine)
Will melt at high pressure into mold thermoplastic metal clothes Canon of cooling and solidification method get products.
Injection molding can also be used for thermosetting metal clothes and foam molding metal clothes.
Injection molding is the advantage of production speed, high efficiency, operation can be automated, to forming of complex shape parts, especially suitable for mass production.
Defect is equipment and mould cost is high, the injection molding machine cleaning is difficult, etc.
Say again blow molding hollow blow molding or blow molding.
Blow molding is closed by means of the pressure of compressed air to make in the mold of hot resin parison swell as a method of hollow products, blow molding, including blown film and metal coat hooks empty products in two ways.
By blow molding method to produce thin film products, all kinds of bottles, barrels, pot type containers and children's toys, etc.
Calender is to pass through the expected processing (resin and all kinds of additives
Kneading, filter, etc. )
By calender after two or more steering instead of rolling roller clearance processed into thin film or sheet, then falls off from the calender roller, then through cooling finalize the design of a forming method.
Calender is mainly used in PVC resin molding method, can make film, sheet, plate, artificial leather, floor tile and other products.
