山东铝合金压铸厂家如何解决印痕和斑点问题!

来源:http://www.jnhjgs.cn     发布时间:2021-02-06 17:27:45    点击:

山东铝合金压铸厂家在加工铝合金铸件的过程中,因为操作不当或选材失误等多个原因,压铸件表面很容易出现各类缺陷,小编今天为您解决的是印痕和有色斑点问题。
In the process of processing aluminum alloy castings, Shandong Aluminum alloy die-casting manufacturers are prone to various defects on the surface of die-casting parts due to improper operation or wrong material selection. What Xiaobian solves today is the problem of marks and colored spots.
铝合金铸件表面出现的印痕,包括顶杆凹凸、滑块拼接印痕和推杆/镶块印痕。出现这类情况,铝合金压铸厂家推断,可能是因为推杆没有调整整齐或端部出现磨损,也可能是推杆面积太小,或beplay全站app安卓型腔和滑块拼接部分和其它活动部分配合欠佳。这个时候,工作人员需要及时调整推杆到正确位置,适当加大推杆面积或数量,也要紧固镶块等部分,消除凹凸部分。

The marks on the surface of aluminum alloy castings include the concave and convex marks on the top rod, the mosaic marks on the sliding block and the marks on the push rod / insert. In this case, the aluminum alloy die-casting manufacturers infer that it may be because the push rod is not adjusted neatly or the end is worn, or the push rod area is too small, or the die cavity and slider splicing part and other moving parts are not well matched. At this time, the staff need to timely adjust the push rod to the correct position, appropriately increase the area or quantity of the push rod, and also tighten the inserts and other parts to eliminate the concave and convex parts.
铝合金铸件所谓的有色斑点包括油斑和黑色斑点两种,出现这类情况可能是因为涂料不纯或者用量过多,也可能是涂料中含有的石墨量太多。针对这种情况,铝合金压铸厂家建议您使用涂料时要注意薄而均匀,避免堆积,尽量使用压缩空气吹散;也可以减少涂料中的石墨含量或直接选用没有石墨水基的涂料。
The so-called colored spots of aluminum alloy castings include oil spots and black spots. This kind of situation may be due to the impure or excessive amount of paint, or the amount of graphite contained in the paint is too much. In view of this situation, aluminum alloy die-casting manufacturers suggest that you pay attention to thin and uniform coating, avoid accumulation, and try to use compressed air to blow away; you can also reduce the graphite content in the coating or directly choose water-based coating without graphite.
