1. High efficiency material utilization (high yield)
The high material utilization of cold forging allows for significant reductions in material waste (scrap) compared to machining for the same geometry.
■ Material Yield Rate (multi-step rivet example)
2. Higher speed, more efficient production
Cold forming allows for high speed manufacturing (around 100 parts/minute) while still maintaining high precision and complex product geometries. No heating of the material is required.
■ Production Speed (multi-step rivet example)
3. Improved product strength by work hardening
Cold forming process design takes fiber flow lines (the crystal structure of metals) into account allowing for stronger more durable parts.
■ Fiber Flow Lines (multi-step rivet example)
4. Cost reductions through customized manufacturing processes
If a customer design(toleranc es, geometry, number of components required, etc) is practical using cold forming, significant improvements in part unit cost and reduced process complexity are possible.
■ Example of our Value Added(VA)/ Value Engineering (VE) through cold forming
Rolled threads enable high-speed thread forming with no material lost as scrap and a stronger product overall because, unlike machined threads, the fiber flow lines of the material are left intact. Rolling also allows for lower costs and better turnaround time than machining.
Materials Possible with Cold Forming
Pure iron, carbon steel, stainless steel, copper, brass, aluminum, titanium, Kovar, and various alloys. Many other metals possible.
Note: We are also able to perform tests to see if a material provided by the customer is forgeable.
Range of Base Material Sizes Possible
Base wire material diameters between 0.2mm and 23mm (0.008in to 0.90 in)
Possible Part Lengths
Part lengths between 1mm (0.04in) and 1,200 mm (47.2in) are possible.
Note: Please consult with us if your part is particularly long.
Tolerances / Precision Possible
Tolerances in the μｍ (micrometer) range are possible.
Note: What tolerances are possible depends greatly on part geometry and material.
