注塑模具在制造過程中會有一些次品或缺陷，我們每一個塑膠模具廠都會非常注重這個問題，下面就一起探討一下，造成缺陷的原因以及補救方法。
There will be some defective products or defects in the manufacturing process of injection mold. Every plastic mold factory will pay great attention to this problem. Let's discuss the causes and remedies of the defects together.
一、注塑模具造成此缺陷的原因
1、 Reasons for this defect of injection mold
(1)熔融溫度不是太高就是太低。
(1) The melting temperature is either too high or too low.
(2)模腔內(nèi)塑料不足。
(2) Insufficient plastic in the mold cavity.
(3)冷卻階段時接觸塑料的面過熱。
(3) During the cooling phase, the surface contacting the plastic is overheated.
(4)流道不合理、澆口截面過小。
(4) The runner is unreasonable and the gate section is too small.
(5)模溫是否與塑料特性相適應(yīng)。
(5) Whether the mold temperature is compatible with the plastic characteristics.
(6)產(chǎn)品結(jié)構(gòu)不合理(加強進古過高,過厚,明顯厚薄不一)
(6) The product structure is unreasonable (the reinforcement is too high, too thick, and the thickness is obviously different)
(7)冷卻效果不好,產(chǎn)品脫模后繼續(xù)收縮。
(7) The cooling effect is not good, and the product continues to shrink after demoulding.
二、注塑模具缺陷的補救方法
2、 Remedy of injection mold defects
(1)調(diào)整射料缸溫度。
(1) Adjust the temperature of the injection cylinder.
(2)調(diào)整螺桿速度以獲得正確的螺桿表面速度。
(2) Adjust the screw speed to obtain the correct screw surface speed.
(3)增加注塑量。
(3) Increase injection quantity.
(4)保證使用正確的墊料;增加螺桿向前時間;增加注塑壓力;增加注塑速度。
(4) Ensure the correct padding is used; Increase the screw forward time; Increase injection pressure; Increase injection speed.
(5)檢查止流閥是否安裝正確,因為非正常運行會引致壓力流失。
(5) Check whether the check valve is installed correctly, because abnormal operation will cause pressure loss.
(6)降低模具表面溫度。
(6) Reduce the mold surface temperature.
(7)矯正流道避免壓力損失過大;根據(jù)實際需要,適當(dāng)擴大截面尺寸。
(7) Correct the flow channel to avoid excessive pressure loss; Appropriately expand the section size according to the actual needs.
(8)根據(jù)所用塑料的特性及產(chǎn)品結(jié)構(gòu)適當(dāng)控制模溫。
(8) The mold temperature shall be properly controlled according to the characteristics of the plastic used and the product structure.
(9)在允許的情況下改善產(chǎn)品結(jié)構(gòu)。
(9) Improve the product structure if allowed.
(10)設(shè)法讓產(chǎn)品有足夠的冷卻。
(10) Try to make the product cool enough.
山東模具制造廠家認為通過對原因和方法的探討，我們可以更加清楚的知道，在注塑模具生產(chǎn)制造過程中應(yīng)該如何減少工廠的損耗了，泰能特塑膠模具廠在此，與大家通過不該提高技術(shù)水平，一起提益，降低成本。
Shandong mold manufacturers believe that through the discussion of the reasons and methods, we can know more clearly how to reduce the loss of the factory in the production process of injection mold. Here, taineng special plastic mold factory is here to work with you to improve the technical level, improve the efficiency and reduce the cost together.
