High-speed presses to mold the effect of high temperature insulation coatings
To speed stamping out a good product, the mold is also very important for high-speed presses, now open a pair of mold price is very expensive, not just to reduce costs to maintain good high-speed presses, the same should maintain good mold, high-speed presses mold in fact is one of the manufacturing apparatus is inseparable from our daily lives, and large sailing aerospace, small commodities, are inseparable from the mold manufacturing and processing, and nearly 95 percent of the work piece to be cast by the multi-mold high temperature, and the temperature height up to 300 degrees. Through various means blow molding, injection molding, stretch, smelting, stamping and other products to obtain the desired shape.
High-temperature insulation materials, can withstand high temperatures up to 1800 ℃, can effectively inhibit a variety of heat conduction and radiant heat, thermal insulation inhibition efficiency up to 95%, every punch die to live more than 85% of calories, causing the internal temperature of a good punch die the outer surface temperature will not burn people. Punch mold surface coatings 1110 ℃ coated 8mm thick, mold surface temperature can be reduced from 1110 ℃ to less than 100 ℃, effective solution to the economic losses caused by constantly changing the punch die.
Due to the shape of the mold are special high-speed presses, so can not use special insulation material insulation, resulting in a lot of mold in the heating process of heat loss, severe heat loss, damage to the punch mold itself is also very serious. Mold heat great loss, not only directly increase the cost of production, but also because of the frequent replacement of punch die causing huge economic losses, thus high temperature insulation coatings came into being.
