Casting system: the plastic melts into a smooth and orderly cavity filling and solidification during the filling process and the pressure is transmitted to all parts, to get organized, clear appearance of the parts. Gating system from the sprue, runner, cold well, pulling rod and gate components. 1: The main channel is generally located in the center line of the mold plastic mold factory in Dongguan, its diameter size of the impact when the pressure drop plastic plastic injection mold, flow rate and filling time. 2: From the sprue runner for the inflow of plastics with allocation and buffer. If the runner cross-section is too small, the filling for a long time, the pressure loss is large plastic mold manufacturers, but may occur lack of material, charred, corrugated, shrinkage and other defects. Section is too large it will increase the amount of recycled material condensed to extend the cooling time. 3: Position the cold slug well opposite end of the main channel or diversion channel. Is mainly used for storage during the injection interval, the nozzle tip caused by a drop in temperature of the heat generated by the cold material. If they enter the flow channel, the flow channel blockage and slow stream velocity; into the cavity plastic mold design, cold material will appear on the product, while in the open mold, cold well they play the main channel of the material from the cold Pull the sprue bush and the runner is fixed in the mold of action. Often associated with pulling rod and thimble conjunction. Mold assembly drawing technical requirements: 1. For the mold some systems performance requirements. For example on the top of the system, pulling the slider assembly requirements of the core structure. 2. The mold assembly process requirements. For example after the bonding surface of the mold assembly parting surface bonded gap should not be greater than the 0.05mm die, following parallelism requirements, noting the size determined by the assembly and the size requirements. 3. Use the mold assembly and disassembly methods. The oxidation treatment, mold number, lettering, signs, seals, storage and other requirements. 5. Requests the tryout and inspection related to plastic mold factory in Dongguan, Foshan, plastic molds, molds Ltd. Shun King by Liaobu Shun King mold. Liaobu Shun King Mold Ltd. (www.shunjingmuju.com/) strong, credible, in Dongguan, Guangdong mold equipment industry has accumulated a large number of loyal customers.
