Industries

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.

The Battery Electrode Slitting scenario for lithium batteries consists of a positive electrode (aluminum foil coated with lithium iron phosphate, ternary materials, etc.) and a negative electrode (copper foil coated with graphite, etc.). Pole slice slitting is the process of longitudinally cutting a large and wide pole slice that has been coated and compacted into narrow strips that meet the requirements for cell winding or stacking. Industry core pain point: Burr control: The positive and negative electrode coatings contain extremely hard active substance particles, and the substrate (copper foil/aluminum foil) is extremely thin (only a few microns). If the blade is not sharp enough or the precision is insufficient, the incision will produce metal burrs. Excessive burrs are a key hazard for lithium batteries to self discharge severely and even puncture the separator, causing short circuit explosions. The industry requires that burrs must usually be controlled within $12 \ mu \ text {m} $or even $5 \ mu \ text {m} $. Powder shedding and scratches: Friction during shearing may cause the coating on the edge of the electrode to peel off (powder shedding) or produce wavy edges, affecting the consistency of the battery cell. Extremely high wear: Positive electrode materials (such as ternary materials) have strong abrasiveness, and ordinary steel knives may wear out in a few hours. Henglida's core products and applications: Lithium ion positive and negative electrode slitting tungsten steel disc cutter (round cutter): Henglida uses ultra-fine grain hard alloy (tungsten steel) as the substrate. This material has extremely high hardness and red hardness. Ultimate machining accuracy: Henglida uses high-precision CNC grinding machines to control the edge roughness, thickness tolerance, outer circle runout, and side runout of circular knives at the micrometer level ($\ le 0.002 \ text {mm} $). Ensure that the blade clearance is absolutely uniform during cutting, achieving a perfect cutting surface without burrs, powder loss, or wavy edges. 2、 The battery separator slitting scenario for lithium batteries is a critical safety barrier that isolates positive and negative electrodes and allows ions to pass through, typically made of polyethylene PE, polypropylene PP, or ceramic coated separators. Diaphragm slitting is the process of cutting a large roll of main film into narrow separators that are compatible with different battery specifications. Core pain points in the industry: Extremely thin and easily stretchable: The thickness of the base film is often only $5 \ mu \ text {m} -12 \ mu \ text {m} $, and the material is extremely soft and elastic. High coating wear: Nowadays, ceramic coatings (such as alumina and boehmite) are commonly used for diaphragms to resist high temperatures. These ceramic particles have a strong wear effect on the cutting edge of the blade. Fuzhing and ruffle edges: If the blade is not sharp enough or there are small gaps, the edge of the diaphragm will become hairy, or uneven force will cause "ruffle edges", resulting in poor alignment during winding. Henglida's core products and applications: specialized slitting knives for diaphragm cutting/ceramic diaphragm knives: In response to the strong abrasion of ceramic diaphragms, Henglida provides specially formulated hard alloy blades or blades with superhard nano coatings (such as diamond coating/DLC). Mirror edge: The blade edge is ultra precision ground to achieve mirror level. This enables the blade to instantly cut open the diaphragm like a hot knife cutting butter during high-speed slitting (up to hundreds of meters per minute), avoiding tensile stress, eliminating burrs and fuzzing, and ensuring smooth winding of the diaphragm edge.

All the various processing procedures of paper boxes cannot do without special industrial blades. The corrugated paperboard production line uses ultra-thin paper-separating blades to divide large sheets, and slotting blades to complete the cutting of paper box openings and pressure lines, resulting in neat cuts without edge bulges. The flat die-cutting machine is equipped with forming knife molds, which can once complete the one-time punching of various shapes and ventilation holes for color boxes, express boxes, and food paper boxes. The cutting circular blades cut the rolled cardboard and gray board paper into strips, and the cross-cutting tools precisely shape the sheets to the standard size. The trimming knife removes the excess edges of the paper boxes, and the waste material crusher blade shreds the paper scraps for recycling and reuse. The blades are made of high-carbon steel and hard alloys, which are sharp and wear-resistant, suitable for high-speed production lines. The cutting process produces little paper debris, does not collapse the paperboard corrugations, stably controls the size accuracy of the paper boxes, and improves the appearance quality and processing capacity of the cartons.

The rubber and tire industry is a very important heavy industry application scenario for its mechanical blades and cutting tools products. Due to the high elasticity, toughness, high viscosity, and susceptibility to heat during shearing of rubber itself, as well as the presence of composite interlayers such as steel wires and fibers inside tire manufacturing, the industry has almost stringent requirements for the wear resistance, impact resistance, and sharpness of blades. The following is an introduction to typical application scenarios of Henglida's related products in the industry: 1. Tool application in the entire tire manufacturing process (Tyre Manufacturing). A tire needs to go through multiple cutting and segmentation processes from raw materials to finished products, and high-precision tools directly determine the dimensional accuracy of semi-finished products and the dynamic balance performance of the final tire. Rubber Slitting&Strip Cutting: Application scenario: After producing a wide width mixed film through mixing and calendering, it is necessary to longitudinally cut it into specific width rubber strips or tapes. Use of cutting tools: rubber slitting disc knife, pneumatic slitting knife, flying knife. Pain points in the scene: The adhesive material is prone to sticking to the knife, and high-speed cutting is prone to heating. High quality blades need to have extremely high sharpness and be coated with anti sticking properties. Cord Fabric Cutting: Application scenario: The skeleton materials of tires (steel cord fabric, fiber cord fabric) need to be precisely cut at specific angles (such as 90 ° or diagonal). Use of cutting tools: steel cord cutting knife (usually a large disc knife or long scissors), fiber cutting knife. Scenario pain points: The steel wire curtain has extremely high hardness, and ordinary blades are prone to breakage or rapid wear. The blade must be made of high alloy die steel (such as Cr12MoV, W6Mo5Cr4V2, etc.) or hard alloy (tungsten steel) to ensure high impact resistance and long service life. Tread&Sidewall Cutting: Application scenario: After the continuous tread is extruded by the extruder, it needs to be cut to a fixed length according to the unfolded length of a single tire (usually using thermal cutting or ultrasonic cutting combined with mechanical structure). Use of cutting tools: tread cutting knife, irregular tooth shaped knife, cutting whole knife. Building&Trimming: Application scenario: During the green tire molding stage or after vulcanization molding, excess rubber edges and bristles (rubber strips generated by exhaust holes) need to be removed from the tire. Use of cutting tools: pneumatic trimming knife, micro trimming round knife, handheld/robotic arm trimming knife. 2、 In addition to tires, in the production of conveyor belts, seals, various types of rubber hoses, and the recycling of waste rubber, cutting tools are also core consumables in the general rubber products and recycled rubber industry.

Tools used: Strong shredder blades (multi claw blades, square blades), tire crusher blades, heavy-duty capacity reducing blades. Pain point of the scene: It needs to withstand extremely high torque and forced cutting of steel wires. The blades are mostly made of heavy-duty high toughness alloy steel and undergo deep heat treatment, with extremely strong anti fracture performance. Conveyor Belt&V-Belt Cutting: Application scenarios: slitting and cutting of industrial conveyor belts and transmission belts before and after molding. Use of cutting tools: irregular tooth shaped flat element knife, strip shaped cutting knife, and slitting round knife. 3、 Henglida's tool technology characteristics in the rubber tire industry. In order to address the three major challenges of "hardness, stickiness, and toughness" in rubber tire processing, professional manufacturers such as Henglida usually provide the following targeted solutions: core dimension solutions and technical applications. Strict material selection includes 9CrSi, Cr12MoV (D2), W6Mo5Cr4V2 (M2 high-speed steel), and hard alloys (tungsten steel). Balancing hardness (wear resistance) and toughness (anti chipping). Customized rubber machinery often uses non-standard and irregular cutting tools (such as special toothed knives and curved bar knives). The manufacturer relies on precision grinding machines and five axis machining centers to achieve high-precision non-standard customization. The special treatment of the cutting edge adopts mirror polishing technology to reduce the roughness of the cutting edge, or special surface spraying (such as anti friction coating) is carried out to effectively reduce the rubber sticking resistance and lower the

Chemical fiber production is the process of transforming chemical raw materials into "silk" or "short fibers", in which blades undertake the key tasks of "shaping" and "fixed length cutting". Staple Fiber Cutting: Application scenario: Thousands of continuous synthetic fibers (bundles) sprayed from the spinneret need to be cut into fixed lengths (such as 38mm, 51mm cotton or wool short fibers) at high speed after stretching and curling, and used as spinning materials. Use of cutting tools: chemical fiber cutting knife, rotating cutting knife ring. Industry pain point solution: Chemical fiber has high friction and is prone to heating during high-speed movement, while ordinary blades are prone to wear or fuse. This scenario uses ultra-fine grain hard alloy (tungsten steel) or ceramic blades, combined with super mirror grinding technology, to ensure that the cutting edge has no micro notches, achieving high stability and high-speed cutting without melt adhesion. Winding&Waste Yarn Tripping: Application scenario: During the high-speed winding process of long fibers, when switching between fiber cakes or generating waste fibers, specific cutting blades or suction gun blades are required to quickly cut them off. Use of cutting tools: air suction gun blades, wire cutter blades. 2、 In the Textile&Non woven Processing industry, as fibers enter the spinning, weaving, printing and dyeing, or non-woven fabric manufacturing stages, cutting tools are mainly used for edge trimming, slitting, and finished product cutting of materials. Non woven Slitting: Application scenarios: Widely used in non-woven fabric production lines such as masks, sanitary napkins, diapers, filter materials, and automotive interiors. After the large roll of non-woven fabric is produced, it needs to be cut into the target width at high speed. Use of cutting tools: pneumatic slitting circular knife, slitting upper/lower knife, ultra-thin slitting disc knife. Industry pain point solution: The non-woven fabric has a fluffy texture and may contain abrasive impurities, requiring the blade to have extremely high sharpness to prevent "drawing" or "burrs" and ensure a smooth and clean incision. Fabric Edge Trimming: Application scenario: Real time online trimming of irregular edges (fabric edges) on both sides of a fabric on a loom (water jet, air jet, rapier loom) or printing and dyeing machine. Use of cutting tools: fabric edge cutter, rotary round scissors, pneumatic edge cutting complete set device. Clothing&Home Textile Cutting: Application scenarios: Used for cutting and trimming textile fabrics, carpets, curtains, etc. in large quantities of finished pieces or specific sizes. Using cutting tools: cutting machine computer driven straight knife, round knife, precision die. 3、 Henglida's cutting tool technology and material advantages in the textile and chemical fiber industry. Chemical fiber textile machinery usually operates at high speed 24 hours a day. In response to this characteristic, professional cutting tool manufacturers generally provide the following technical support: core technology dimension solutions and performance. Cutting edge materials are widely used, including Vangard (powder high-speed steel), hard alloys (tungsten steel), and high-performance ceramics (zirconia/alumina composite materials). The wear resistance of ceramic and tungsten steel blades is tens of times that of ordinary steel blades. The high surface finish of the blade is achieved through mirror level grinding (mirror polishing) on both sides and the cutting edge. The Ra value is extremely low, greatly reducing the friction coefficient between the fiber and the blade, preventing static electricity accumulation and chemical fiber hot melt adhesion. The combination of ultra-thin and high rigidity cutting disc cutter achieves ultra-thin (even less than 1mm) while maintaining excellent flatness and rigidity, ensuring that the cutting tool does not shake or jump at high-speed cutting speeds of over 1000 meters per minute.

Industry pain points: Relatively weak profit margins, extremely dependent on large-scale production and refined warehousing and logistics management. 2、 The Four Core Pain Points of the Packaging and Printing Industry If you are preparing to collaborate with companies in this industry or are empowering digitalization/business for this scenario, the following pain points are the most concerning for this industry: Pain point one: Difficulty in color management ("what you see is not what you get") Different batches of paper, ink, and printing machines can all cause color deviation. Customers have almost strict requirements for brand colors (such as "Coca Cola Red"), and how to achieve standardized color management is the core. Pain point 2: The subsequent processes are complex, and production scheduling and pricing are extremely complicated Printing is just the first step, followed by more than ten processes such as die-cutting, hot stamping, box pasting, and assembly. This leads to extremely complex BOM (Bill of Materials), making it difficult for traditional ERP to accurately calculate costs and schedule production. Pain point three: Orders show a trend of "multiple varieties, small batches, and urgent delivery" Affected by e-commerce and personalized consumption, the number of large orders that used to be hundreds of thousands has decreased, while the number of customized orders that were thousands or even hundreds has increased. This places extremely high demands on manufacturers' ability to quickly sample and change versions. Pain Point Four: Environmental Protection and Compliance Pressure The control of VOCs (volatile organic compounds) emissions, the application of water-based ink, and the replacement of green biodegradable materials are the environmental hard indicators that printing enterprises must face. 3、 Industry Transformation Trends: Digitization and Intelligence Currently, excellent packaging and printing enterprises such as "Henglida" are generally transforming towards the following directions: Intelligent typesetting and layout: Utilizing AI algorithms to automatically combine different orders on limited paper, minimizing paper scraps waste (paper costs account for 50% -60% of total costs). Intelligent factory (MES system): Introducing a production execution system to monitor the real-time startup rate, vehicle speed, and number of printed sheets of the printing machine, achieving full process traceability of production. The introduction of digital printing technology: filling the gap of traditional offset printing, without the need for plate making, printing from one sheet, perfectly solving the needs of small batches and personalized customization.
