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. Drying temperature above 80 ℃, more than 2 hours and gate design mold common mold temperature control was 80-90 ℃, flow channel diameter 3-6mm pom500p, the gate length of 0.5mm, gate size and wall thickness depending gum given DuPont pom500p, should be at least 0.5 to 0.6 times the product thickness of the gate diameter circular, rectangular gate width is typically 2 or more times the thickness, the depth of the wall thickness 0.6 times higher toughness pom500p, 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 speed injection speed too fast for plastic materials pom500p, 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 if necessary and recommended materials plastic materials offer application please contact Density g / cm339 absorption% 2 continuous use temperature and the company ℃ -50--110 yield anti- tensile yield strength MPa63 ultimate tensile strength tensile strain% 10% 31 MPa ultimate tensile strain impact toughness Kj / m notch impact toughness Kj / ㎡6 Shore hardness of Rockwell hardness MPa135 MPa85 bending strength MPa modulus of elasticity MPa2600 soften temperature ℃ 150 Heat distortion temperature HDT ℃ 155 Hotline expansion coefficient of a thermal conductivity W / (m × K) 031 35 DuPont friction coefficient pom500p, pom500p, wholesale spot by Dongguan Chang Ping Jichang plastic materials.
