塑模进胶口设计（Mold gate design） The basal area of gate type and special type of gate gate micro formability after finishing processing and other characteristics of direct gate 1. good formability, after the processing difficulties of the 2. Gate Department prone to the residual stress of staying. Flat film gate gate 1. good difficult good formability, after processing difficulties of the 2. flow marks or directional good, prevent deformation effect of ring gate 1. round gate forming easily, after processing difficulties. The 2 is mainly suitable for cylinder parts, a hole can be finished, with no good good for gate slightly slightly 1 side gate one line lug, can solve the gate of staying the residual stress problem to side gate 1. gate section can be changed arbitrarily, also can do a plurality of gate, or gate 1. And in a number of local affiliated gate can also be prone to adverse circumstances 2. spray trace of the pin gate Tunnel Gate small student gate, 1. gate blockage situation unnecessary in forming automatic cut down the number of which is conducive to automatic forming. The 2. traces of the gate is not obvious, usually do not have after processing. The 3. gate pressure loss, high injection pressure must be. The 4. part is the residual gate staying resin curing blocking only. 9. disc gate: the circumference of the products and the expansion of feed, the feed point symmetry, filling evenly, can eliminate the combined line. For the exhaust nozzle. Common punching removal, design when punching process of.10. fan gate: from the shunt to the cavity gradually enlarged fan-shaped, suitable for long or flat and thin products, can reduce the flow stress and orientation. The fan angle is determined by the shape of the product, the area is not greater than the cross gate cross-section area of.11. ring gate along the entire outer circumferential expansion into the plastic products, it can make the plastic around the core of uniform filling, good exhaust, reduce the combined
