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.

　　當注（zhù）塑加工產品塑料件從模具中脫模時，如果使用頂杆，頂杆往往會在塑料件上留下（xià）深或淺的痕跡。如（rú）果（guǒ）這些痕跡（jì）太深，就會出現所謂的丁白現象（xiàng），嚴重的會發生所謂的頂（dǐng）爆。塑料件出現頂白現象的主要原因是產品粘（zhān）著力大，塑料件頂出位置造成頂杆頂（dǐng）出位置有白痕。具體原因及改進方（fāng）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:

　　後模（mó）具（jù）溫度過低或過高：調整合適的模具溫度。

　　After the mold temperature is too low or too high: Adjust the mold temperature.

　　彈射速度過快：減慢彈（dàn）射（shè）速度。

　　Ejection speed too fast: Slows down ejection speed.

　　有脫模倒角：修模(拋光)。

　　With demoulding chamfering: trimming (polishing).

　　成品頂出不平衡(頂出板彈簧斷裂)：檢修模具(使頂出平衡)。

　　Unbalanced ejection of finished product (ejection plate spring is broken) : overhaul the mold (make ejection balance).

　　頂（dǐng）針數量不足（zú）或位（wèi）置不當：增加頂針數（shù）量或改變頂針位置（zhì）。

　　Insufficient or improperly placed thimbles: Increase the number of thimbles or change the position of thimbles.

　　脫模時模具內出現真空現象：清理頂部針孔內的汙漬，提高進氣（qì）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（dǎ）磨每個骨位、柱位。

　　Rough bone position and column position of finished product (inverted) : polish each bone position and column position.

　　注入壓力或保壓壓力過大（dà）：適當降（jiàng）低壓力。

　　Injection pressure or holding pressure is too large: reduce the pressure appropriately.

　　成品後模脫模斜度過小：加大後模脫模斜度。

　　If the demoulding slope of finished die is too small, increase the demoulding slope of finished die.

　　側（cè）滑（huá）塊動作時間或位置（zhì）不當：檢修模具(使抽芯動作正常)。

　　Side slider action time or position is not appropriate: repair mold (make core pulling normal).

　　頂針麵積太小或頂出（chū）速度（dù）太快：增加頂針麵積或降低頂出速度。

　　Too small thimble area or too fast ejection speed: Increase thimble area or reduce ejection speed.
