MAANSHAN, CHINA — In the demanding world of modern manufacturing and metal processing, the quality of a cut begins long before the machine is turned on—it starts in the metallurgy and heat treatment of the blade itself. Maanshan Licheng Blade Manufacturing Co., Ltd. has established itself as a trusted leader in this space, combining elite material science with cutting-edge production techniques to deliver industrial cutting tools built for ultimate durability and precision.

At the core of Licheng’s manufacturing philosophy is an uncompromising dedication to material integrity. The company utilizes a comprehensive selection of both high-quality imported and premium domestic materials, carefully chosen to match the rigorous demands of heavy industry. However, selecting the right raw steel is only the first step. To unlock the full potential of the metal, Licheng employs a suite of advanced heat treatment processes, including:

Vacuum Heat Treatment: Minimizes distortion and surface oxidation, ensuring structural uniformity throughout the blade.

Subzero Heat Treatment: Drives retained austenite out of the steel, significantly boosting wear resistance and dimensional stability.

Salty Bath Heat Treatment: Provides rapid, uniform heating for exceptional hardness and toughness balance.

These sophisticated thermal processes fundamentally enhance the inner character and micro-structure of every knife, resulting in superior edge retention, impact resistance, and an extended operational lifespan even under extreme industrial conditions.

Specialized Solutions for the Metallurgical Industry

While Licheng caters to a diverse global industrial base, the company is primarily renowned for its specialized engineering of metallurgical industry blades. Designed to withstand high-stress environments, heavy thermal loads, and continuous operation, Licheng’s core product lineup includes:

Round coil slitting knives - Manufactured to exact tolerances for smooth, burr-free rotary cutting and slitting applications across various metal gauges. Suitable for mild, chopper, aluminum steel, pickling lines, silicon steel etc. Cutting capacity ranging from 0.05mm to 25mm thick coil strips.

Steel shear blade - The surface finish has a great impact on the accuracy and durability of the steel shear blade. The grinding surface of the blade is actually formed by countless scratches scored by a large number of abrasive particles on the grinding wheel. Engineered for clean, high-precision shearing of heavy plates, offering exceptional impact toughness to prevent chipping or cracking under high tonnage.

Silicon Steel Slitting Blades: Specially crafted for the high-precision processing of electrical silicon steel—a material notorious for demanding flawless edge quality and extreme wear resistance to prevent burrs that could compromise electrical core performance.

Through the synergy of classic craftsmanship and innovative metallurgy, Maanshan Licheng blade manufacturing co., LTD. we use a wide range of high-quality imported and local materials, along with advanced heat treatments, including vacuum heat treatment, subzero heat treatment, and salty bath heat treatment, to ensure a better performance of the inner character of knives.
