济南注塑加工后容易出现一些不太好的问题，比如说丁白现象，当然很多人不知道这是怎么形成的以及怎么去，下面我们就来看看吧。
Jinan injection molding processing is prone to some not good problems, such as ding Bai phenomenon, of course, many people do not know how this is formed and how to solve, let's see.
当注塑加工产品塑料件从模具中脱模时，如果使用顶杆，顶杆往往会在塑料件上留下深或浅的痕迹。如果这些痕迹太深，就会出现所谓的丁白现象，严重的会发生所谓的顶爆。塑料件出现顶白现象的主要原因是产品粘着力大，塑料件顶出位置造成顶杆顶出位置有白痕。具体原因及改进方法如下：
When plastic parts of injection molding products are demoulded from the mold, push rods often leave deep or shallow marks on the plastic parts if they are used. If the marks are too deep, what's called a tinting phenomenon can occur, and in severe cases, what's called a top burst. The main reason for the top white phenomenon of plastic parts is that the product adhesion is large, and the top position of plastic parts causes white marks on the top position of the push rod. Specific reasons and improvement methods are as follows:
后模具温度过低或过高：调整合适的模具温度。
After the mold temperature is too low or too high: Adjust the mold temperature.
弹射速度过快：减慢弹射速度。
Ejection speed too fast: Slows down ejection speed.
有脱模倒角：修模(抛光)。
With demoulding chamfering: trimming (polishing).
成品顶出不平衡(顶出板弹簧断裂)：检修模具(使顶出平衡)。
Unbalanced ejection of finished product (ejection plate spring is broken) : overhaul the mold (make ejection balance).
顶针数量不足或位置不当：增加顶针数量或改变顶针位置。
Insufficient or improperly placed thimbles: Increase the number of thimbles or change the position of thimbles.
脱模时模具内出现真空现象：清理顶部针孔内的污渍，提高进气效果。
Vacuum phenomenon occurs in the mold during demoulding: clean the stains in the top pinhole and improve the air intake effect.
成品(倒扣)的粗骨位、柱位：打磨每个骨位、柱位。
Rough bone position and column position of finished product (inverted) : polish each bone position and column position.
注入压力或保压压力过大：适当降低压力。
Injection pressure or holding pressure is too large: reduce the pressure appropriately.
成品后模脱模斜度过小：加大后模脱模斜度。
If the demoulding slope of finished die is too small, increase the demoulding slope of finished die.
侧滑块动作时间或位置不当：检修模具(使抽芯动作正常)。
Side slider action time or position is not appropriate: repair mold (make core pulling normal).
顶针面积太小或顶出速度太快：增加顶针面积或降低顶出速度。
Too small thimble area or too fast ejection speed: Increase thimble area or reduce ejection speed.
