Generally, in the secondary automatic packaging production line, the required case sealing machine and carton forming machine adopt carbon steel structure design; however, some special industries such as salt industry, chemical industry, food industry, and pharmaceutical industry are excluded. The material of those industry’s equipment must have the requirements of corrosion resistance, good oxidation resistance, and high hygiene level; how should we to choose?
First of all, the metal material must be chrome-plated and nickel-plated stainless steel material, and this material should meet the international standard 304 level above can be met; at the same time, according to the material performance requirements of different industries, the material can be selected from the stainless steel chromium content parameters, determine According to the following:
1.The corrosion resistance, toughness and weldability of stainless steel containing 15% to 30% of chromium are all increased with the increase of chromium content. The corrosion resistance and oxidation resistance are better, but the mechanical properties and process performance are poor. Mostly used for acid-resisting structures with not stressed or used as oxidation-resistant steels ;
2.The stainless steel material containing more than 18% chromium, and also containing 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements, the overall performance is good, can resist a variety of media corrosion; this type of material has good plasticity, toughness, weldability, Corrosion resistance and non-magnetic or weak magnetic, good corrosion resistance in oxidizing and reducing media, used to make structural acid-proof equipment;
Just last month, one customer ordered from us one set packing line,include stainless steel automatic carton packer and carton sealer machine. This customer industry belongs to the food industry and must strictly control food hygiene.After inspection,they chosen our 304 stainless steel box opener and stainless steel box sealing machine, which can be used in any environment, without rust and oxidation, high hygiene level; click to view video.
