Henghui specializes in manufacturing high-quality custom trimming dies according to your specific drawings and requirements. Our precision tools are engineered for superior performance and extended service life.

Trimming dies are screw-forming tools designed to create precise head shapes on bolts and screws. Common configurations include square, hexagon, and octagon profiles for various industrial applications.

• Forming hex head and square head bolts
• Removing distorted angular parts from screw heads
• Achieving high-precision sizing without resizing processes

Available in various materials including M2, M35, DC53, SKD11, D2, SKH-9, and SKH-51. Optional Tin/TiALN coatings significantly extend tool lifespan.

Our trimming dies are produced using advanced manufacturing technologies:

• High-precision grinding centers
• High-speed machining centers
• Wire and electrode EDM systems
• CNC lathes for hard lathing (steel and carbide)

Please provide diameter, height, and across flat dimensions when inquiring or ordering. Alternatively, submit your technical drawings for custom manufacturing.

Henghui maintains strict quality control throughout the manufacturing process. All carbide cold forged dies undergo regular inspection using three-dimensional measuring equipment to ensure precision and reliability.
