Your present position：Home > The injection molding process and molding Foundation
After cooling and molding injection molding products after you have an open mold process, the mold is basically anti-mold process of mold opening segment, there was a slow setting, mold is completed, the product must ejection process.
I. top front:
Before the best of the top two classes, the first stage can be divided into medium voltage slow, that is part of the product out, and then the top of medium pressure medium speed, medium pressure medium speed generally refers to the 35% -55 %, while there may be a low speed to 5%, which is subject to different products, the top of the stroke length setting is slightly higher than the top of the vertical thickness of product can be 1-2cm.
Two. Retreat needle
Top retreat consists of two processes with the top down is basically the same, should be reserved for the top end back 1-3cm of space, in order to protect the top thimble tubing is not bad.
Three. Thimble way
Including a multiple top, staying single and thimble top choice, robots take product release have taken a number of circumstances, in order to prolong the life of the thimble cylinder several times to no more than three times on the top is appropriate, thimble stay general used in a thimble with product returns are likely to produce damage mold growth products, as well as with the use of robots, sometimes they need a shorter stay thimble.
Injection molding process based on:
● temperature, pressure, speed, and cooling control purposes, the operation and results of
● Multi-filling and multi-stage holding pressure control; crystallization of non-crystalline and molecular / fiber row to the impact of process and quality
● internal stress, cooling rate, contraction of the plastic parts plastic quality of
● plastic rheology: Plastic how flow discharged to the changing viscosity, shear and molecular / fiber discharged to the relationship
● gating system, cooling system, the mold structure and the relationship between the injection molding process
