The limitations of the single mode molding equipment market

Forming mechanism according to the needs of the product has a variety of forms, mainly divided into including compression molding equipment ( Moulding) , extrusion molding equipment ( Extrusion molding) , injection molding equipment ( Injection molding) , blow molding equipment ( Hollow molding) And rolling molding equipment, etc. （ A) Also calls the moulding or pressure molding, compression molding is mainly used for phenolic resin, urea formaldehyde resin, unsaturated polyester resin, thermosetting plastic molding; ( 2) Continuous extrusion molding equipment is heated resin by mould, extrusion equipment of the required shape products. Sometimes do on thermosetting plastic extrusion molding, and can be used for foam plastic forming. Extrusion can be extrusion products of various shapes, the advantages of high production efficiency, can be automated, continuous production. ( 3) Injection molding equipment is thermoplastics melt under high pressure into mold Canon of cooling and solidification get products equipment. Injection molding can also be used for thermosetting plastic and foam plastic molding; ( 4) By the pressure of compressed air blow molding equipment makes closed in the mold of hot resin parison swell for hollow products equipment, blow molding, including blown film and two methods of hollow blow molding products; ( 5) Rolling molding equipment is to pass through the expected processing (resin and all kinds of additives Kneading, filter, etc. ) After by two or more calender to instead of the calender roll gap processed into film or sheet, then falls off from the calender roller, and then after cooling finalize the design of the forming equipment. Calender is mainly used in PVC resin molding method, can make film, sheet, plate, artificial leather, floor tile and other products. At present, the plastic molding is relatively single, efficient performance of plastic molding machine on the market, basically are imported from abroad, the technology of productivity and the rapid development of plastic molding equipment. The market need is the development progress and innovation, with the development of the society it is not hard to find, a single plastic molding already cannot satisfy the demand of the market. Extrusion molding equipment cannot be widely applied to hot solid plastic processing, otherwise it will cause errors occurring in the size of the products; And high cost of mold and injection molding equipment, the cleaning is relatively difficult, the emergence of these problems illustrates the plastic molding equipment market need to improve the forming rate and yield, and in the development of high performance by mold, and the research and development is the main direction of the high speed, high efficiency, energy saving, environmental protection and quality control.
