Core Materials: The Invisible Cornerstone of Tool Performance

·High-grade alloy steel: Main tools (e.g., wrenches, pliers, cutting tools) use premium alloy steel, with some high-end series integrated with S390PM powder high-speed steel technology. Through the synergistic ratio of tungsten, cobalt, vanadium and other elements, it achieves dual advantages of high wear resistance + high toughness. For example, cutting tools made of this material have a 60% lower wear rate and 3-5 times longer service life than ordinary steel, maintaining stable hardness even at 600℃.

·Practical engineering materials: Handles of hand tools are made of non-slip insulated engineering plastic via two-shot injection molding—tough and impact-resistant inner layer, and 1000V-rated insulated outer layer, suitable for electricians and outdoor operations. Core components of measuring tools use high-precision metal substrates, ensuring measurement error within industry standards.

Precision Craftsmanship: Key to Easy & Durable Tools

·Heat treatment: Adopting three-time tempering + deep cryogenic treatment, the residual austenite content is reduced to below 5% with deformation ≤0.05mm, ensuring precise dimensions after long-term use.

·Surface treatment: Tools like wrenches and pliers undergo corrosion-resistant treatments (e.g., chromium plating, black oxide), effectively resisting rust in humid environments (e.g., outdoor construction, marine engineering auxiliary operations) to extend service life.

·Ergonomic design: Tool shapes are optimized for ergonomics—e.g., box-end wrenches feature 12 contact points for uniform torque transmission and anti-slip performance; screwdrivers have magnetic bits to adsorb screws in narrow spaces, preventing drops.
