Precision metal processing cheap plastic molds _ _ Shi sharp precision metal processing

 Plastic products, mold will be out today, melting spot, crazing, crack. Transparency of information on PC, plexiglass precision metal processing affordable, some hours can be able to see a few little wrinkles gleaming through the light, which is also called the bright spots of wrinkles, can also be called crack. This is due to the application of force straight direction tensile stress occurs, tends to make the polymer molecules in the active direction, so that trends tend to some and not a somewhat different index of refraction, the light refraction so happened crazing division occurs through two interfaces . If showing how it should deal with these questions it? 1: The first plastic drying, dry to abundant noise. 2: barrel temperature can be lowered to a temperature appropriate to improve injection mold. 3: Injection pressure is applied to some lower injection speed. 4: speak up to the trough and see the exhaust is not smooth. 5: the adjustment of the back pressure presses down screw speed. 6: a look at the material mouth there is no blocking. Currently, the share of plastic mold in the mold industry share of about 30%, the proportion of exports and imports in the mold up to 50 to 70 percent, while in recent years, the rapid development of China's plastic mold. The increasingly widespread use of plastic products, plastic mold to provide a very broad market. China's mold industry trading market is very large precision metal processing, and each year also showed a 15% to 20% of trend growth, mainly due to the development of China's automobile, home appliances, IT industry, packaging, building materials, daily necessities, such as mold large user industry . In recent years, precision metal machining cheap, China's plastic mold manufacturing level has been greatly improved, the weight of a single set of large plastic mold production has reached more than 50t, precision precision plastic mold has reached 3cm, multi-cavity plastic molds have been able to 7800 production of a mold cavity plastic mold, high speed extrusion molds capable of producing speeds of up to 4m / min or more high-speed plastic profile extrusion die and the main profile double-lumen extrusion mold. With the improvement of the rapid development of the plastics industry and general engineering plastics in terms of strength, range of applications is constantly expanding plastic precision metal processing where the good, the amount of plastic products is on the rise. It is understood that China's output of plastic products in 2012 nearly 60 million tons, and the process continues to grow, we can see that domestic demand in China's plastic mold industry has a huge impetus.
