Analyzing Cold Heading Kinematics, Substrate Plasticity, and Global Supply Optimization
Unlike conventional cut tapping, modern thread-rolling (forming) creates a zero-clearance internal mating thread via plastic deformation. This process causes grain structure flow along the profile contours, yielding high pull-out resistance, superior fatigue life, and zero chip contamination in cleanroom and electronic setups.
To combat boss bursting in brittle thermoplastics and light casting alloys (e.g., magnesium and cast aluminum), custom trilobular geometries create localized yield relief zones. This substantially drops driving torque while retaining peak break-away and stripping ratios across high-speed robotic screwdriving operations.
Effective self-tapping performance mandates dual-tier metallurgical control: a surface case depth of 450–750 HV for thread generation against tough counter-substrates, backed by a ductile core structure (280–380 HV) to absorb dynamic shear vectors and mechanical vibration without brittle failure.
Eliminating supply bottlenecks through multi-tier internal routing: cold heading, high-speed thread rolling, in-house carburizing, and automated optical validation.
Equipped with 3-die 3-blow, 4-die 4-blow, and 6-die multi-station cold heading configurations in our Dongguan, Shaoguan, and Wuhan plants. High-speed progressive forming minimizes cold-work stress fractures while optimizing continuous metallurgical flow lines.
Automated glass turntable visual sorting systems verify 100% of fastener outputs across critical parameters: head diameter, recess concentricity, pitch angle, thread lead, and washer sealing seating, eliminating line downtime on high-volume automated lines.
