Why choose composite rolling for paper guillotine knife
- Jul 12, 2018 -

The bimetal composite materials produced by the composite rolling include steel-steel, copper-steel, aluminum-aluminum alloy, aluminum-copper, steel-titanium, aluminum-zinc and the like. The composite rolling method has the advantages of flexible production, simple process, high dimensional accuracy, stable performance and good quality, and can realize mechanization, automation and continuous production. High production efficiency, low cost, saving precious metals and so on. Take paper guillotine knife for example, to get good cutting, we apply better material HSS to make the edge, and paper guillotine knife is just normal Q235B. If the whole knife is HSS material, the cost is super high, but adopting composite rolling, it saves a lot with good cutting performance.
