The KTH Group manufactures high-quality automotive parts starting with the raw material to the blanking, laser welding, stamping, spot welding and delivery to our customers – just in time for their assembly.
Production begins in the Stamping Department when coils of sheet steel arrive on the dock. Depending on the process required to make the parts, the steel is either cut into blanks, to make the shape more closely represent the part, or the entire coil is moved to the stamping press. The steel is then punched, bent, formed, drawn, and trimmed into the desired shape. Stamped parts are compared with the forming simulation analysis and the products’ designs to validate the parts’ quality.
Types of Stamping:
- Blanking – rough shape taken from coil steel.
- Trim Form – larger parts that require edges to be trimmed.
- Progressive – dies with many operations, typically used for small parts.
- Transfer – systems that move the steel blank from one die station to another
Types of Dies:
- Compound die-blanks and perforates a part at the same time in the same station. They commonly run as single-hit dies.
- Progressive die-provides an effective way to convert raw coil stock into a finished product with minimal handling.
To ensure the parts’ quality, from raw material all the way to final components, inspectors are positioned at every press to thoroughly check each part before it advances to the next stage in the process.
KTH has a die maintenance department that maintains, repairs, and modifies our dies.
