YG10X YG20C YG11 TC Wire Drawing Dies For Screw Making

Blank inspection-All PCD, MONO/SSCD, ND, and TC dies produced by Coolervie are checked under Microscope by 100X material
magnification, so that dies with any impurities, cracks and spots could be easily detected and rejected. If these cracks or spots
exist, the abnormal internal-stress will cause die cracking during die manufacturing or wire drawing process.

◆Outer casing production:Only high-quality casing can be a good carrier for high-quality dies. Coolervie uses excellent
stainless-steel materials, and completes three sets of process: cutting casing, creating setting area, and creating blank area in
the cutting process of fully automatic machine tools, ensuring the perfect concentricity without moving the die shell.
◆ Reinforcement-Diamond should be firmly protected by metal matrix, which is formed by the sintered metal powder, reinforcing
diamond to endure wire impact without breaking and to extend wire die life. Coolervie's auto-sintering process is accomplished by
the combination of an infrared sensor, auto-feeder and a high frequency sintering machine.
◆ Coning-An automatic turning machine completes front and back cones and two parallel flats.
◆ Cylindrical grinding-In order to ensure the precise dimension and roundness of casing, every casing should be ground by
centerless grinding machine to tightly control the tolerance within 5 microns.
◆ Laser die profile drilling-The precision and consistency of our dies profiling has been improved dramatically since we purchased
a state-of-art laser die drilling unit. A double side profile drilling is achieved by this most up-to-date laser drilling
machines.

Chongqing Henghui Precision Mold Co., Ltd. is a professional enterprise that specializes in the production of screw molds. With a strong technical team, we ensure professional production and maintain strict quality control. Our main production includes standard and non-standard special screw molds.

We can also produce and customize molds based on our customers' requirements, such as straight body, shrinking die, closing die, strong binding die, as well as multilateral main dies such as triangle, hexagon, and more. Additionally, we offer carbide upper and lower punching and punching sleeves, sleeves, combined die sleeves, cutters, thread rolling dies, Six-Lobe thimbles, Six-Lobe protection sleeves, and punching needles with various specifications like straight body, step, tail hole, and more.

We also provide screw forming molds such as punch, thread plate (thread rolling die), and many other specifications. Our molds cover a wide range of products, including bolt molds, automobile fastener molds, wheel hub bolt molds (rear wheel hub bolt, wheel hub bolt, fixed bolt, wheel bolt, and tire bolt), high-strength fastener molds for wind power (tower bolt mold, complete machine bolt mold, and blade bolt mold), as well as high-strength bolt molds for steel structures in construction.
