濟(jì)南注塑加工后容易出現(xiàn)一些不太好的問題，比如說丁白現(xiàn)象，當(dāng)然很多人不知道這是怎么形成的以及怎么去，下面我們就來看看吧。
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.
當(dāng)注塑加工產(chǎn)品塑料件從模具中脫模時(shí)，如果使用頂桿，頂桿往往會(huì)在塑料件上留下深或淺的痕跡。如果這些痕跡太深，就會(huì)出現(xiàn)所謂的丁白現(xiàn)象，嚴(yán)重的會(huì)發(fā)生所謂的頂爆。塑料件出現(xiàn)頂白現(xiàn)象的主要原因是產(chǎn)品粘著力大，塑料件頂出位置造成頂桿頂出位置有白痕。具體原因及改進(jìn)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:
后模具溫度過低或過高：調(diào)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：減慢彈射速度。
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).
頂針數(shù)量不足或位置不當(dāng)：增加頂針數(shù)量或改變頂針位置。
Insufficient or improperly placed thimbles: Increase the number of thimbles or change the position of thimbles.
脫模時(shí)模具內(nèi)出現(xiàn)真空現(xiàn)象：清理頂部針孔內(nèi)的污漬，提高進(jìn)氣效果。
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：打磨每個(gè)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：適當(dāng)降低壓力。
Injection pressure or holding pressure is too large: reduce the pressure appropriately.
成品后模脫模斜度過?。杭哟蠛竽Ｃ撃Ｐ倍取?/div>
If the demoulding slope of finished die is too small, increase the demoulding slope of finished die.
側(cè)滑塊動(dòng)作時(shí)間或位置不當(dāng)：檢修模具(使抽芯動(dòng)作正常)。
Side slider action time or position is not appropriate: repair mold (make core pulling normal).
頂針面積太小或頂出速度太快：增加頂針面積或降低頂出速度。
Too small thimble area or too fast ejection speed: Increase thimble area or reduce ejection speed.
