管材挤出机挤出丝锥

在管道连接、阀体制造和各种机械设备的装配中,高质量的内螺纹是保证密封性能、安全性和耐用性的核心,但传统切割丝锥在加工过程中往往面临排屑难、易磨损、螺纹精度低等挑战,针对这些行业痛点,祖安工在创新驱动下,推出了这款专为高标准管螺纹加工而设计的挤压丝锥。

卓越的遗产:来自日本NACHI的优质基础材料

刀具的性能从它的基材开始。对于ZUANGONG管材挤出机挤出丝锥的“心脏”——它的核心基材——我们毫不妥协地选择了日本著名特殊钢企业NACHI的HSSE含钴高速钢。
NACHI is renowned worldwide for its consistent production system from material development to finished products and its dedication to premium quality. The HSSE cobalt-containing high-speed steel it produces boasts the following extraordinary properties:
Ultra-high hardness and wear resistance: The addition of cobalt significantly enhances the steel’s red hardness and wear resistance at high temperatures. Even under continuous, high-speed machining conditions, the tap maintains long-lasting sharpness and dimensional stability.
Superior toughness: Through a special melting and heat treatment process, the internal structure of the material becomes more uniform and pure, effectively reducing the formation of microcracks. This endows the tap with excellent impact toughness and greatly lowers the risk of edge chipping or fracture during machining.
Choosing NACHI HSSE as the base material is like infusing our tap with a robust "skeleton" and "bloodstream", laying a solid foundation for its unparalleled performance.

ZUANGONG Tap Products

    Triple Protection: Cutting-Edge Coating Technology for Diverse Working Conditions

If top-tier base material is the "inner strength" of a tap, then advanced coating technology is its indestructible "armor". ZUANGONG equips its Extrusion Taps for Pipe Extrusion Machines with three high-performance coatings to accurately tackle a variety of complex machining environments and material characteristics.

These three coatings are like equipping a valiant warrior with battle armors of distinct functions. Whether you’re facing hard "boulders" or sticky and tough "marshes" in machining, there is always one option to help you work with ease and conquer every challenge.

Core Advantages: Why Choose ZUANGONG Extrusion Taps for Pipe Extrusion Machines?

  • Chip-free machining for greater environmental friendliness and efficiency: As an extrusion tap, it forms threads through metal plastic deformation with no chips generated, completely solving the chip removal problem of cutting taps. It is particularly suitable for blind hole machining and keeps the working environment cleaner.
  • Higher thread strength: Threads formed by extrusion feature continuous, unbroken metal fibers. Thus, their tensile strength, shear strength and fatigue resistance are all superior to those of cut threads.

    • Exceptional surface finish: Extrusion machining work-hardens the thread surface for an ultra-high finish, resulting in low friction torque and superior sealing performance.
    • Extra-long service life: The powerful combination of high-quality HSSE base material and high-performance coatings endows the tap with incredible durability, effectively reducing the frequency of tool replacement and overall production costs.
