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 ℃, the flow channel diameter 3-6mm, the gate length is 0.5mm, depending on the size of the plastic wall thickness of the gate The set, round gate diameter should be at least 0.5 to 0.6 times the POM plastic thickness of high strength plastic, rectangular gate is usually twice the width or thickness of more high lubricity POM plastic rubbing depth of the wall thickness of 0.6 times between stripping slope 40'-1 ° 30 '. 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 shelf POM plastic materials (1) Japan / Taiwan Polyplastics with the company: M90-44 (Injection level), M90-04 (injection grade), M25-44 (high viscosity) POM plastic materials price quotes, SX-35 (toughened grade).
