company news about Process requirements for high-quality steel filing cabinets

Steel filing cabinets are very common in daily life. They are simple in structure but very practical. If you have bought steel filing cabinets, you will find that the price difference of cabinets of the same style will be very large, and the price difference also reflects the difference in the quality of steel filing cabinets to a certain extent. What is causing this? In fact, this is inseparable from the production process of steel filing cabinets.

The steel filing cabinet looks very simple in structure, but it is not easy to make a high-quality steel filing cabinet. It has very strict requirements on the craft.

First of all, let's talk about the selection of materials. If you want steel filing cabinets to be strong and durable, you must choose high-quality cold-rolled steel plates with a thickness of 0.5mm or more. The bending performance and stamping resistance of the steel plate should be good, and it should also have good anti-strike ability.

The second step in making steel filing cabinets is cutting and stamping. The steel plate should be flat when making stamping parts, and the radius of the hemmed round flute of various steel file cabinet parts should not be greater than 2.5 times the thickness of the plate.

Welding is a very important step in the production of steel filing cabinets. All welded parts should be flat and firm, without obvious protruding marks, and the uniform weld mark height should not be greater than 1mm. There should be no weld penetration, weld bead, false welding, spatter and other defects. Anything is unqualified. The spot welding of the welded parts of the file cabinet should be firm and reliable, and the welding points should be uniform, and the welding should not be welded through. The diameter of the solder joints is 3-8mm, and the solder joint spacing should be controlled within 100mm.

In addition, the surface treatment process of the filing cabinet is also very important. All the sheet metal parts of the steel file cabinet must undergo pre-treatment processes such as water washing, degreasing, pickling, phosphating, etc., before using environmentally friendly powder for electrostatic spraying. When sprayed, the color should be uniform, and there should be no obvious lumps, wrinkles, bottoming and other defects that affect the appearance. It should be smooth and even.

The above is the manufacturing process requirements of steel filing cabinets. The fineness of the craftsmanship greatly affects the quality of steel filing cabinets.
