One  working principle:    The liquid nitrogen is used to make the flash of the rubber and plastic hardware products brittle quickly, and then the high-temperature jet of cold-resistant rubber particles hits the flash edge, thereby removing the burrs and not changing the shape and nature of the product, and not damaging the perfect effect of the product, is manufacturing high-grade The precision of the perfect product must be modern equipment. It can greatly improve the edge-removing efficiency and trimming precision of rubber and plastic products, aluminum-magnesium die-casting products. two  Machine use: An article suitable materials: various types of rubber material (including silica), injection molded parts, magnesium alloy, aluminum alloy, zinc alloy.                          2 Applicable products industry: 3C industry such as automobile, aerospace, computer, communication, home appliance, etc. three  Machine features: four  Technical features: 1 It can remove the complicated structure, the small rubber and plastic products of any shape, the polyurethane products and the flash of the magnesium alloy castings. 2 The trimming precision is high, which can remove the tiny and hidden flash. (up to 1/100mm accuracy) 3 high production efficiency, a frozen trimming machine is equivalent to 80-120 skilled workers per day. 4. Does not damage the surface of the product, improve the appearance quality of the product, and increase the service life of the product.  5 pass rate \ trimming quality is high, the qualified rate of finished products is maintained above 98% . (can significantly reduce the scrap rate)   6 covers a small area, a frozen trimming machine plus ancillary equipment only 10 square meters, can save valuable land area.  7 reduce the cost of raw materials, can greatly reduce the loss of waste rubber. The requirement for the mold for freezing and trimming is that the flash edge should be as thin as possible ( below 0.2mm ), the overflow tank should be as small as possible, and there is no need to leave a torn edge, which can save the mold cost greatly; 1/5-1/10 of the mold .  8. Reduce management costs, because a large number of manual trimming work is reduced , and the operator only needs to put the product, press the button, and take out the product. It can save a lot of labor and management costs. 9. It can enhance the image and competitiveness of the company. Whether it is high value-added or low value-added products, everything can be solved.
