Processing Technology:

Standardized, assembly line production: Includes heat treatment processes such as brazing, quenching, and tempering, as well as laser 3D printing technology.

Alloy Characteristics: Utilizes the world's most advanced coarse-grained tungsten carbide alloy with a micro-aging dispersion strengthening design. The hardness of the cemented carbide tip exceeds HRA86 (hardness > HV0.22300) and its bending compressive strength > 3500 MPa; it also boasts superior thermal stability.

Tooth Manufacturing Process: The tooth body exhibits impact toughness > 80 J and bending strength ≥ 2100 N/mm². A deep cryogenic heat treatment process ensures the tooth body maintains high hardness while possessing excellent toughness.

Welding Process: The alloy brazing interface strength > 250 MPa. Utilizing a self-developed precipitation-strengthened copper-based brazing filler metal, the bond between the alloy and the matrix is ​​more reliable.

Product Manufacturing Process Characteristics:

1. New 3D Printing Technology: LEMHUNTER's "Freeform" 3D printing technology, developed for defense needs, is used in the manufacture of cutting teeth. It is the only manufacturer internationally to apply laser 3D printing technology to cutting teeth manufacturing. Utilizing ultra-hard "Superhard" technology and super-wear-resistant "SuperWear" materials, its lifespan is exponentially longer than traditionally manufactured cutting teeth.

2. Alloy: Utilizing the world's most advanced coarse-grained tungsten carbide alloy with a microscopic aging dispersion strengthening design, its lifespan is significantly improved compared to traditional alloys. The tooth body uses military-grade high-purity matrix materials and undergoes an additional "quenching and tempering" special heat treatment process, resulting in excellent combined high hardness and high toughness, making it wear-resistant and less prone to breakage.

3. Based on 3D printing and combined with independently developed composite materials, the company's cutting teeth have a significantly longer service life than leading international brands, and are internationally leading in spark control, improving operational safety.

4. After more than 20 years of material research, the company has perfectly solved the problem of metal teeth's lack of wear resistance, thus achieving a perfect match between the tooth body and the alloy's uniform wear. This prevents premature alloy breakage and fracture caused by excessive tooth wear and loss of alloy protection.

5. The company's independently developed and optimized tooth profile design perfectly matches various equipment, achieving perfect self-rotation, reducing uneven wear and tooth breakage, improving mining efficiency, and protecting equipment from damage.

6. Hengpu's three-dimensional biomimetic structure "3D-B&F" technology, with its adaptive rotation function, prevents uneven wear. The company's cutting teeth have an ultra-long service life, saving time and mining costs, and increasing the mining rate per unit time.
