Professional Stainless Steel Flat Thread Rolling Die Manufacturer
High-Precision Flat Thread Rolling Dies for Stainless Steel Bolts & Screws
As a premier flat thread rolling dies manufacturer in China, FMT specializes in high-durability solutions specifically engineered for stainless steel thread making. Processing stainless steel requires tools with exceptional hardness and toughness due to the material's work-hardening nature. Our stainless steel screw thread rolling dies are designed to deliver superior precision, ensuring smooth thread profiles and consistent quality for high-demand industries like automotive, aerospace, and precision machinery.
Superior Material & Engineering: Why Choose FMT Thread Plates?
The core of our stainless steel bolt thread rolling die lies in our selection of premium mold steel. Unlike standard SKD11, our specialized tool steel offers double the toughness, significantly reducing the risk of edge chipping or collapsing during cold work.
To ensure long-term stability, we utilize high-temperature tempering to eliminate residual stress from wire-cutting processes. This meticulous approach prevents deformation and cracks in precision molds, maintaining the tight tolerances required for stainless steel screw plates. Whether you are sourcing from China or looking for Taiwanese-quality standards, our dies provide the durability needed for high-volume production.
Specialized Heat Treatment & Custom Design
Every stainless steel thread plate we produce undergoes a proprietary heat treatment process. This optimizes the hardness-to-toughness ratio, specifically tailored to handle the resistance of stainless steel alloys (such as SUS304 or SUS316). Unlike ordinary iron thread rolling dies, our tooth geometry and surface treatments are customized to adapt to various specifications, significantly extending the service life of the tool and reducing your cost per part.
How to Thread Stainless Steel: The Rolling Process
The stainless steel screw thread rolling process is a cold-forming method that reshapes the semi-finished blank into a finished thread. The principle involves one stationary flat thread die and one reciprocating movable die. As the blank is compressed and rolled between the two plates, the material undergoes plastic deformation to form the thread profile. This process not only maintains the grain flow of the metal but also enhances the fatigue strength of the stainless steel bolt compared to cutting methods.
