PEEK belongs to high temperature and special engineering plastics thermoplastic material, through processing and injection molding.
PEEK products general injection molding dimension precision can reach 0.
1 mm or so, when the injection molding processing according to the different wall thickness, different structure of products, size accuracy can be controlled at 0.
About 015 mm.
PEEK under the high temperature of the melt liquidity is poorer, and the need to maintain temperature of around 385 degrees.
For injection molding machine cylinder heating section to steadily provide heating temperature above 350 degrees.
PEEK under the molten state of viscosity is larger, the injection molding processing need pressure is higher, more wear and tear of the screw, need injection molding function to provide a bigger injection pressure.
Early PEEK injection molding processing materials is applied in military industry, aerospace, and medical industry on materials with high heat resistance, high precision, oil resistant, wear-resisting and so on high performance requirements of top industry.
But with the expansion of PEEK application, our side can also see this kind of material.
the liquidity of the commonly used plastic mold design requirements can be divided into three categories of
thermoplastic liquidity size, general but from the size of molecular weight, melt index, Archimedes spiral flow length, apparent viscosity and flow ratio ( Flow length/plastic pieces of wall thickness) And a series of index are analyzed. Small molecular weight, broad molecular weight distribution, the regularity of the molecular structure is poor, high melt index, long length of spiral flow, low viscosity, flow ratio of the liquidity is good, for the same commodity plastics must check the specifications to judge whether its liquidity is suitable for injection molding. Changshu mould company in accordance with the requirements of mould design of commonly used plastic liquidity can be roughly divided into three categories: (1) liquidity good
PA, PE, PS, PP, CA, poly ( 4) Methyl defensibly olefin; (2) liquid medium series of polystyrene resin ( Such AS ABS, AS) , PMMA, POM, polyphenylene ether; (3) illiquid
PC, hard PVC, polyphenyl ether, polysulfone, aromatic sulfone, fluorine plastics.
is carried out in accordance with the steps to design better plastic cover mould produce
in people's life, has used plastic products are more common, it can see plastic products are widely used in people's life, and plastic products manufacturers, is also very much, this also makes the development of the industry, plastic products are need to mould, plastic mould design completed a mold production, also can saying is the generation of plastic products. Know about mold design can be briefly, the design is in order to better to imagine into practice, so the design is also needs to be done step by step, generally speaking, mold design is also a need to draw the drawings, it can produce mould, and at the time of design or want to consider many factors, for mold, practicality is must consider, plastic mold design of product is also must have the workability. Is carried out in accordance with the steps to design better plastic mold production, this will not be prone to errors, so it is more reliable, everything done is need to be carried out in accordance with the steps, so the mould design is not exceptional also, after the knowledge for the plastic mold design, and know more about to die. Changshu plastic mould company is carried out in accordance with the steps to design and manufacture of plastic mold, have what not understand can contact us!
