_PMMA V045-68209 important role. High mold temperature, melt filling products easily, the apparent good, small internal stress, and the products can also improve plating or 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 and performance requirements are relatively high, mould temperature can control in 60 70C?. And the mold temperature should be uniform requirements between the mold cavity and the mold core temperature difference should not exceed 10 products for deep hole products or more complicated shape, requiring the cavity temperature slightly higher than the core temperature, in order to facilitate the smooth demoulding products.
The real demonstration of interoperability between PBT technologies (PBTPE) has also been successful in June 2007. This, on the other hand, verifies that PBT technology has low complexity and is based on existing Ethernet hardware implementations, concise technology, and standardized research.
Attitude and practice at this stage some mainstream operators, and commercial test of PBT technology and some other operators, the PBT with its technical characteristics and verified the cost of business model, has gradually become a global network operators transformation on the road to a "straight opening".
POM medicine and 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 and steel in many parts, since its inception, POM has been widely used in electronic and electrical and machinery, instrumentation, automotive, building materials, daily light industrial, agriculture and other fields. Used in many new fields, such as medical technology, sports equipment and 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 and 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
