Cold Forging vs. Hot Forging in Surgical Instruments – And Why Rigor Instruments Excels at Both
In the competitive world of surgical instrument manufacturing, the forging process plays a pivotal role in determining an instrument’s strength, precision, and reliability. Two primary methods are used in the industry: cold forging and hot forging. At Rigor Instruments, we are proud to offer in-house capabilities for both processes, giving our clients a unique edge in product quality and customization.
What is Cold Forging?
Cold forging involves shaping metal at or near room temperature using high-pressure dies. It’s a process best suited for small, high-precision components where dimensional accuracy and surface finish are critical.
Benefits of Cold Forging in Surgical Instruments:
Exceptional surface finish – reduces the need for extensive polishing
High dimensional accuracy – ideal for fine instruments like scissors and forceps
Enhanced material strength – due to strain hardening
Efficient and repeatable – perfect for high-volume production runs
Commonly Cold Forged Instruments:
Needle holders
Scalpel handles
Micro forceps
Tungsten carbide jaw inserts
What is Hot Forging?
Hot forging involves heating the metal above its recrystallization temperature (typically around 1,100°C for stainless steel) before shaping. This process is ideal for creating larger or more complex tools that require significant forming.
Benefits of Hot Forging in Surgical Instruments:
Easier forming of complex or thick parts
Excellent internal grain structure for durability
Suitable for titanium and orthopedic-grade alloys
Lower die stress – allows broader shape flexibility
Commonly Hot Forged Instruments:
Orthopedic tools (bone levers, rongeurs, chisels)
Trauma plates and implants
Retractors and osteotomes
