東莞市千泰塑膠原料有限公司為您提供pc//8701-15///拉鏈。pc//8701-15///拉鏈 long term supply of abs mold temperature: mold temperature on the surface roughness of abs products, reduce the internal stress of the product has an important role. high mold temperature, melt filling products easily, the apparent good, small internal stress,&the products can also improve plating/high, but there is also a molding shrinkage rate, long processing cycle, easy demoulding after modification problem. general requirements for products, mold temperature control in 40? 50x:; products for surface&performance requirements are relatively high, mould temperature can control in 60 70c?.&the mold temperature should be uniform requirements between the mold cavity&the mold core temperature difference should not exceed 10 products for deep hole products/more complicated shape, requiring the cavity temperature slightly higher than the core temperature, in order to facilitate the smooth demoulding products.
pbt technology in the true sense of interoperability demonstration (pbtpe (edge device)) has also been successfully carried out in june 2007. on the other hand, it is verified that the pbt technology has the advantages of low complexity&low cost, which is based on the existing ethernet hardware implementation, the technology is -&the standardization research is low.
attitude&practice at this stage some mainstream operators,&commer-l test of pbt technology&some other operators, the pbt with its technical characteristics&verified the cost of business model, has gradually become a global network operators transformation on the road to a "straight opening".
pom medicine&disinfection, chinese development status of /pom (pom) with formaldehyde is lower than that in many other engineering plastics cost, are replacing some of the traditional metal is occupied by the market, such as alternative production of zinc, brass, aluminum&steel in many parts, since its inception, pom has been widely used in electronic&electrical&machinery, instrumentation, automotive, building materials, daily light industrial, agriculture&other fields. used in many new fields, such as medical technology, sports equipment&so on, pom also showed good growth.
pc "plastic cup can be resistant to -30-140 degrees temperature, the physical properties of materials, it is said that this material in this temperature is not cracking&melting, but this is not from the food safety point of view, in the high temperature biphenol a precipitation, is harmful to the body, have been reported that will affect the male sexual function, in some western canada has banned the use of pc" material do cups, bottles etc.. zui is to use pc security during the "material cup of hot water, not to be placed in the microwave heating. d, injection pressure is too low, improve the injection pressure
e, feeding amount too small - adjust the feed quantity
5, contraction vacuum bubble
a, holding enough - dwell time
b, mold temperature is too low, increasing the die temperature
