Metal processing, slitting
Industry pain points and challenges: Strict precision requirements, especially for new energy vehicle battery electrodes, motor silicon steel sheets, high-end home appliance boards, etc., with width tolerances after slitting, edge burrs (Burr) of shear bands, and sickle bending requirements reaching micrometer level ($\ mu m $). Excessive burrs can directly lead to short circuits in later stages of lamination (such as lithium batteries) or damage to stamping molds. High strength material hardening: With the popularity of high-strength steel (such as automotive ultra high strength steel DP1180, etc.), ordinary blades are prone to wear and breakage, leading to frequent downtime and tool replacement. Henglida's core products and applications: high-precision longitudinal cutting disc cutters (Metal Slitting Knives): Henglida uses high-quality alloy tool steel (such as Cr12MoV, H13, HSS) and hard alloy (tungsten steel), and through strict vacuum heat treatment, the blade hardness is high and the inside and outside are uniform. The thickness tolerance can be controlled within $\ pm 0.001 \ textmm $(1 micron), ensuring that the edges of the metal strip after slitting are smooth and free of burrs. Rubber Spacers&Rubber Rings: In the slitting process, the clearance between the blades and the accuracy of the sleeve determine the cutting quality. Henglida provides high-precision matching gaskets to ensure absolute precision of the tool shaft assembly. 2、 Metal Cut to Length&Flying Shear is the process of cutting a continuous metal coil into a single sheet according to a set length. Commonly seen in high-speed flying shear lines and longitudinal and transverse composite lines in steel mills. Industry pain points and challenges: huge impact force: When cutting thick plates (such as carbon steel plates over 10mm), the blade bears a huge mechanical impact force in an instant, and its toughness is insufficient, making it prone to fracture. Continuous high-speed operation: The flying shear line belongs to non-stop cutting, with extremely fast speed (up to hundreds of meters per minute), and the blade must maintain a sharp edge under high temperature and high-frequency impact. Henglida's core products and applications: Heavy duty shearing machine blades/Shear Blades: Henglida produces straight blades that are several meters long and have excellent impact toughness and red hardness. For thick plate shearing, impact resistant modified tool steel is used; For thin plate cutting, emphasis is placed on the ultimate sharpness and wear resistance of the cutting edge, ensuring that the cutting surface is vertical and not flanged. 3、 In the subsequent processing of metal sheets, it is necessary to bend them into specific geometric shapes (such as building color steel tiles, automotive structural components, machine room cabinets, etc.) in the metal cold bending and stamping processing scenario (Roll Forming&Press Brake). Industry pain points and challenges: The accuracy of bending molds directly affects the angle and straightness of workpieces. If the surface of the mold is rough or the hardness is not sufficient, it will deform under high-intensity compression or leave serious scratches on the surface of the metal sheet, damaging the anti rust coating. Henglida's core products and applications: CNC bending machine molds (Press Brake Tooling): Henglida not only produces blades, but also provides various standard and non-standard customized bending machine upper molds, lower molds, and CNC segmented molds. The product has undergone high-frequency quenching treatment, resulting in high durability. With high-precision geometric dimensions, it can achieve precise bending angle control.
