Cutting and compensating plate for flatbed die cutting machine

Provide with consumable products for manual, semi and fully automatic flatbed die cutters; our products have strict technology and stable quality which are durable in hardness, flatness and parallelism.

Material of die cutting plate

The material requirements for automatic die cutting plates are high, as they have to withstand high temperature, high pressure, high speed, and high frequency impacts and friction, while also ensuring flatness and hardness.

The commonly used materials for die cutting steel plates include stainless steel, which is a corrosion-resistant alloy steel containing elements such as chromium and nickel. It has good heat resistance and wears resistance, but has low hardness and is suitable for flat or circular flat automatic die-cutting machines.

Manganese steel: It is a type of carbon structural steel with a high manganese content, which has high strength and toughness, can resist impact and fatigue damage, but is prone to rusting. It is suitable for automatic die-cutting machines for circular pressing.

Imported material: With ultra-high hardness and wear resistance, it can adapt to various types of automatic die-cutting machines.

The key mission of the die cutting steel plate remains unchanged: to transform the designer's drawings into physical entities that are not inferior to millimeters with certain rigidity and very flatness. It silently carries, but defines the upper limit of quality. On the contrary, the die cutting steel plate will determine the scrap rate of the product.

Precision laser cutting and strict heat treatment ensure the sharpness and toughness of the steel plate blade.

The use of die cutting plates

The essence of die-cutting is the process of converting kinetic energy into deformation energy, and the die cutting plate plays a pivotal role in this process. When the cutting die impacts the material at a speed of 5-20m/s, the steel plate needs to evenly spread the shock wave to the entire pressure bearing surface within milliseconds to avoid energy concentration at the cutting edge and causing blade breakage. The secret lies in the elastic modulus and internal damping characteristics of steel, which can both resist deformation rigidly and absorb residual vibrations through microscopic lattice vibrations. Experiments have shown that using composite steel plates with increased damping coefficients can prolong the life of the cutting die. Especially when die-cutting brittle materials such as fiberglass boards, the suppression of rebound vibration by steel plates directly affects whether micro cracks are generated in the cut.

When the die-cutting machine pulls the die cutting plate, the negative pressure airflow generated instantly will suck the loose paper on the platform into the bottom of the knife mold, which may scratch the printing surface or cause the card plate to stop. Traditional steel plates form a "paper chip trap" due to their right angled edge design; while 45 ° chamfered steel plates combined with embedded sponge strips achieve waste guided collection. We are well aware that steel plates are not only pressure transmission media, but also key hubs for clean production. By strengthening the crystal structure of the steel plate through 1200 tons of hydraulic quenching, the bending strength is increased by 300%, completely eliminating positioning deviation caused by steel plate deformation. Choosing a good factory to customize steel plates is equivalent to installing "dust lungs" and "voltage stabilizers" on the equipment, making each batch of die-cutting smoother. The die-cutting pressure needs to be accurately matched with the material characteristics, not enough to cause burrs, and too much to damage the blade.

The service life of die cutting plate

According to the characteristics of the processed material: material hardness and wear resistance: cutting corrugated cardboard, cardboard, adhesive and other relatively soft materials, steel plate wear is slow. Cutting materials such as plastics, composite materials (especially those containing glass fiber, carbon fiber, metal foil, etc.), leather, rubber, and other materials with high hardness or strong wear resistance will significantly accelerate the wear of steel plates. The abrasive components in materials, such as sand particles and fillers in cardboard, and reinforcing fibers in composite materials, can accelerate the wear of the blade like sandpaper. Adhesive/Coating: Adhesives or coatings on certain materials may have some corrosiveness or increase friction, accelerating wear. When cutting ordinary paper/stickers, the lifespan of high-quality die cutting plates can reach millions of times.

Our company specializes in customizing die cutting plates for various flatbed die-cutting machines and hot stamping machines, supporting customization according to equipment models and compatible with semi-automatic/fully automatic die-cutting machines.

Applicable fields: Packaging printing, hot stamping process equipment matching. Customers can determine the steel plate material to be used based on their desired steel plate material, as well as the size, thickness, and die-cutting material of the steel plate, resulting in different die-cutting pressures; After selecting the materials, customize the steel plate size according to the paper feeding size of the die-cutting machine. Chromium plating or nitriding treatment significantly improves the wear resistance and rust prevention ability of steel plates.
