PBTpolypropylenePA66

Welcome to our high-quality plastic injection molding services made in China. As a leading manufacturer and supplier, we are equipped with advanced equipment and technology. Feel free to request customized products from us. - **Product Name:** Plastic Injection Molding Services - **Material:** PA66/PA6/PBT/PC/PP/PPS/POM with GF/FR/Toughening agent - **Color:** Customizable - **Certification:** ISO9001, SGS, CTI, ROHS - **Mould Material:** P20/718/738/NAK80/S136 - **Mould Base:** LKM Mould Base **Screw and Barrel:** Due to the characteristics of PA, such as toughness and self-lubricity, the screw requires concentrated compressed exhaust gas, strong feeding ability, and good wear resistance. The plasticizing system includes a long feeding section and a deep screw groove. - **Nozzle:** Low viscosity and good fluidity in the molten state require a self-locking nozzle to prevent waste material. - **Product Manufacturability and Mold Design:** Ensure minimal wall thickness to maintain product performance and strength. - **Shrinkage Rate:** Large shrinkage rate facilitates easy demoulding with a draft angle of 40′ -1 40′. - **Flow Path and Gate:** Diameter specifications ensure optimal performance without overheating. - **Inserts:** Metal inserts require careful consideration due to nylon's thermal expansion. - **Exhaust Viscosity:** Proper venting is crucial to avoid defects like bubbles and burns. - **Molding Process:** Drying PA before molding is essential to prevent defects and maintain mechanical properties.
