Tape slitting is a critical process in tape production and processing, requiring adaptation to the characteristics of different tape types—such as BOPP transparent tape, double-sided tape, foam tape, and masking tape. Some are as thin as 20μm (e.g., ultra-thin tape for the electronics industry), ... Read More

Circular slitting blades are core tools in industrial slitting processes (for materials like paper, film, metal foil, and non-woven fabrics). Their mounting type directly impacts slitting precision (e.g., dimensional deviation, edge burrs), equipment operational stability (e.g., vibration, noise), ... Read More

In industrial high-temperature scenarios (such as metal smelting, aero-engine components, and high-temperature molds), the core of material selection lies in "high-temperature resistance + adaptation to working condition requirements." Cemented carbide and ceramic are the two most commonly used high... Read More

Cemented carbides composed of tungsten carbide (WC) as the hard phase and cobalt (Co) as the binder phase are rare industrial materials that “retain hardness even at high temperatures." Their maximum continuous operating temperature can reach 800°C, and they can withstand short-term temperatures ... Read More

Cemented carbide—an alloy made primarily of tungsten carbide (WC) and binders like cobalt (Co) or nickel (Ni)—is celebrated for its exceptional hardness, wear resistance, and heat resistance (withstanding temperatures up to 1,000°C). These properties make it an indispensable material across ... Read More

Cemented carbide products with tungsten carbide (WC) as the core raw material are widely recognized as "highly wear-resistant materials" in the industrial sector. Their wear resistance far exceeds that of ordinary steel, cast iron, and even ceramics, allowing them to be used continuously for ... Read More

In flat knife applications (such as die-cutting, trimming, and stamping), professionals have long been troubled by two issues: pure steel flat knives wear quickly, while pure tungsten carbide flat knives are costly and brittle. In reality, "steel-inserted tungsten carbide flat knives" are already a ... Read More

In the slitting process of corrugated paper processing, many professionals wonder: Why can’t a single knife be used like cutting ordinary paper, but instead a combination of "upper knife + lower knife" is necessary? The core reason lies in the special multi-layered wave structure of corrugated paper... Read More

In the corrugated paper processing chain, slitting is a critical link connecting "raw paper rolls" to "finished cardboard/cartons." It involves cutting large corrugated paper rolls into specified widths or lengths based on downstream needs (e.g., carton dimensions, packaging specifications). However... Read More

In the cemented carbide industry, many people know it is "hard and wear-resistant" but are unclear about its specific material composition. In fact, cemented carbide is not a single material but a composite made by combining "hard phases," "binder phases," and small amounts of "additive phases" in ... Read More
