Most of the plastic molds we use today are mostly made of medium-thick aluminum sheets. Compared with the previous casting molds, aluminum molds have a long service life and do not fall off. The initial cost of mold manufacturing with aluminum plates is slightly higher, but the service life of aluminum molds is much higher than other materials, and the waste aluminum can be recovered and preserved, so the cost performance is higher.
Aluminum alloy materials are particularly prone to top injuries and scratches during stamping production. For the case where the number of projects is not affected, the punching holes are arranged as much as possible in the later engineering punching holes. Even for products with a large number of punching holes, it is considered to do more engineering and punching the punching holes. It is represented by 6061T6 and mainly contains magnesium and silicon. 6061 is a cold-processed aluminum forged product suitable for applications requiring high corrosion resistance and oxidation resistance. Good usability, excellent interface characteristics, easy coating and good processability. Can be used on low pressure weapons and aircraft joints. General characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability, excellent processing performance, good corrosion resistance, high toughness, no deformation after processing, easy color film, excellent oxidation effect And other excellent features. It is a kind of alloy with a wide range of promising applications. Now some of the harder molds are made of 2 and 7 series aluminum plates, which have high hardness but are not suitable for cutting. The cost is relatively high. Therefore, more people use 6-series aluminum plates.
