Aluminum alloy stamping because the material is relatively soft relative to the metal iron, expensive, easy to break and part of the aluminum alloy products need to follow-up processing, such as drawing ﹑ anodized, etc., in the stamping production is particularly prone to top injury, scratch, Manufacturing to pay special attention to the following:
1, for the case does not affect the number of projects in the case of punching as far as possible behind the project punching, and even for the number of punching more products can be considered to do a project should also be punching behind the red.
2, aluminum is soft and mold easier to block material, so when the design of the mold put the gap should be placed on both sides of the material thickness of 10% gap, the depth of the knife to 2MM is more appropriate, the taper to 0.8-1 ° for the appropriate.
3, bending molding, due to aluminum in the bending when the aluminum is easy to produce, will cause injury ﹑ indentation, aluminum raw materials need to paste PE film, in the case of roller and plating,
Forming blocks are preferred for polishing hard chrome.
4, for the need to be processed after the stamping parts of the anode, if flattened, push the flat process 180 °, the product can not be completely pressed, fully pressed will produce spit acid phenomenon, need to stay 0.2-0.3MM seam, so that acid smooth Timely outflow, so in this process must be done on the limit block and calibration mold is higher than the mold.
5, because the aluminum material is more brittle, easy to crack, especially in the case of rebounding, so try not to do pressure line, even if you want to do, but also to do a little wider pressure line, lighter.
