The world of custom sheet metal, the precision of metal laser cutting, and the role sheet metal fabrication companies play in providing high-quality products to industries such as aerospace, automotive, construction, and electronics.

Bending

At Hongsinn, bending is one of the most common sheet metal forming processes. This process requires specialized bending tools, such as a press brake. Sheet metal bending is a fast, accurate, and cost-effective process primarily used to bend sheet metal along a straight line. The sheet metal is placed or clamped into place, then bent to the desired angle using a press brake. This method not only improves efficiency but also ensures a high-quality finished product.

This sheet metal forming process is commonly used for body parts, housings, and electrical components. It can be performed on most compatible sheet metal materials, such as stainless steel, brass, aluminum, and galvanized steel. However, this method has some limitations; for example, the sheet metal needs to be of consistent thickness, and thicker materials are more difficult to bend.

Curling

Crimping is a process that adds hollow, round rollers to the edge of a metal sheet. This not only creates a smooth edge, improves safety during operation, but also enhances structural strength. During the crimping process, the metal sheet is fed into a machine that slowly rolls the edge into a smooth, rounded shape. Certain crimping features may require specialized tooling, while the machine may need to handle complex shapes or tight rollers. This process is widely used for a variety of metal products requiring enhanced edge strength and safety.

Depending on the thickness and ductility of the metal, most metals can be processed through the coiling process, including steel, aluminum, and brass. This process is widely used in HVAC, appliance manufacturing, and for edge treatment of architectural panels, trim, or casings, effectively enhancing the strength and aesthetics of the product.
