Product Q&A

Q:What is multi station cold heading?

Multi-station cold heading is a metal cold forming process that can complete multiple forming operations at room temperature on a single machine, and is used for mass production of high-strength fasteners and custom metal components.

Q:What advantages do cold heading parts have compared with CNC turning parts?

The cold heading process can maintain the complete metal fiber structure, thereby enhancing the tensile strength and fatigue resistance. This process has a higher material utilization rate, generates less waste, has a faster production speed, and ensures stable size consistency for large-scale orders.

Q:What materials can you process for multi station cold heading?

We offer carbon steel, alloy steel and stainless steel, and can comply with DIN and other international industry standards.

Q:Can you produce non-standard customized cold heading parts?

Yes. We provide OEM services based on customer drawings or samples, covering mold development, sample prototyping and mass production.

Q:What secondary processing can you provide?

We can carry out secondary processing with CNC, heat treatment, galvanizing, black oxidation and other surface treatments.
