Auto parts, forged parts, stamping parts, etc. that are recycled by automobile manufacturers are all relatively medium-sized objects. The turnover boxes made of ordinary materials such as wood boards and plastics cannot withstand such large load requirements, so heavy-duty turnover iron boxes emerged as the times require. The need for safe and efficient turnover of auto parts.

The turnover iron box uses cold-rolled steel plates, and the surface is sprayed with plastic to ensure that the surface of the metal turnover box is smooth and clean, without defects such as cracks, welding burrs, and welding penetration. The manufacturing process of heavy-duty turnover iron boxes: black blank→remove surface dirt→chemical rust removal→phosphating→plastic spraying→leveling and solidification→finished product.

The manufacturing process of another foldable iron box is: raw material (carbon steel) → cold rolling forming → fixed length, flat head → punching (welding) → correction → surface spraying → packaging → finished product. Foldable turnover iron boxes can be used repeatedly, with low single-use cost and low recycling cost. They can effectively replace wooden box packaging.

Heavy-duty turnover iron boxes, both non-foldable and foldable, are commonly used by auto parts companies. In automobile supply chain management, the folding design of turnover iron boxes can save logistics costs for enterprises. Use uniform specifications of turnover iron boxes, which have large capacity and better safety performance, making it easier to store goods and count inventory.
