POM POM plastic injection molding process water absorption, typically 0.2% to 0.5%. Under normal circumstances, POM POM material can be processed without drying, but the material must be dried to moisture. The drying temperature is above 80 ℃ POM plastic, more than 2 hours and gate design mold common mold temperature control for 80-90 ℃ POM particles flow channel diameter 3-6mm POM plastic, the gate length is 0.5mm POM, gate size depending on the wall thickness may be plastic, thickness of the article should be at least 0.5 to 0.6 times the diameter of the circular gate, the gate width of the rectangle is usually 2 or more times the thickness, the depth of 0.6 times the wall thickness, stripping slope 40 '-1 ° 30' between. The exhaust system POM-H thickness 0.01-0.02mm wide 3mmPOM-K 0.04mm thickness 3mm wide melt temperature method can be used to measure air-launched POM-H can be set to 215 ℃ (190 ℃ -230 ℃) POM-K can be set to 205 ℃ (190 ℃ -210 ℃) mold temperature of 80 ~ 105C. In order to reduce shrinkage after molding can choose higher mold temperature. Common injection speed for speed too fast, too slow and easy to produce ripples, too easy to produce grain and shear shot overheating. Injection pressure 700 ~ 1200bar back pressure as low as possible, generally no more than 200bar plastic materials offer if necessary and recommended materials application, please contact the company. Can replace most of the non-ferrous metals, automobiles, machine tools, instrumentation internal parts, bearings, tight firmware, gears, springs, pipes, conveyor belts accessories, electric kettles, pump casing, drain devices, such as POM plastic faucet |.
