Parts & Consumables
A good leather punching machine needs quality consumables. Like maintaining a car, knowing parts like backing pads and dies is key to product quality. Below, we introduce common accessories to help you maintain your equipment.
Precision Tools for CNC Punching
Digital Punch Needles
Digital punch needles are essential consumables for CNC punching machines, offering high-precision cutting for materials like leather, fabric, and paper. They come in various types to suit different applications, ensuring efficiency and accuracy in automated punching tasks.
Ordinary Type: These are standard, single-blade needles designed for everyday straight or simple hole punching. Made from durable materials like high-speed steel or tungsten carbide, they provide reliable performance for basic tasks, with diameters ranging from 0.5mm to 10mm. Ideal for high-volume production, they feature efficient waste ejection and long lifespan.
Special Patterned Type (Precision Carving Needles): Also known as Jingdiao or precision carving punches, these needles create intricate designs and complex shapes. With fine, multi-edged tips, they're perfect for detailed engraving on soft materials, supporting vacuum-assisted waste removal for clean results.
Multi-Needle Base Type (Combination Punch Knives): These consist of multiple needles mounted on a single base, allowing simultaneous punching of patterns or holes. Known as combination tools, they boost efficiency for repetitive tasks, customizable for specific layouts like grids or custom arrays.

Precision Tools for Mold Punching
Die Punch Needles
Die punch needles are vital components in mold punching systems, enabling precise cutting and shaping of materials like metal, plastic, and composites. A single mold can incorporate hundreds to thousands of these needles, with diameters, sizes, and patterns freely customizable for flexible layouts and high-efficiency production.
Ordinary Round Hole Punch Needles: These standard needles create clean, circular holes in materials. Crafted from durable alloys like high-speed steel, they offer consistent performance for basic punching tasks, with diameters from 0.1mm to 20mm. Ideal for mass production, they ensure minimal wear and easy integration into molds.
Special Patterned Type (Precision Carving Needles): Also known as Jingdiao punches, these feature intricate shapes for complex designs and engravings. With multi-faceted tips, they're perfect for detailed patterns on various substrates, supporting custom configurations for advanced manufacturing needs.

Essential Cushioning in Molding
EVA Foam Consumables
EVA foam is a lightweight, flexible consumable material widely used in mold punching and manufacturing processes. It serves as a protective layer, offering excellent shock absorption, vibration dampening, and thermal insulation to safeguard tools and materials from damage during high-pressure operations.
Position: Typically positioned as backing or padding between mold plates, punch needles, and workpieces to ensure even pressure distribution and prevent scratches or deformations.
Common Thicknesses: Ranges from 0.5mm to 20mm, with popular options like 2mm, 5mm, and 10mm for varying levels of cushioning in precision tasks.
Alternative Materials: Other options include PU (polyurethane) foam for higher durability, rubber sheets for anti-slip properties, silicone pads for heat resistance, and PE (polyethylene) foam for cost-effective insulation.

Essential Backing in Die Punching
Cardboard
Cardboard acts as a protective backing or padding in die punching machines, absorbing impact to prevent damage to molds, punches, and workpieces while ensuring precise cuts.
Position: Placed between the mold plate, punch needle, and material for even pressure distribution.
Common Thicknesses: Typically 0.5mm to 2mm, with 1mm being popular for lightweight cushioning.
Common Materials: Recycled paper pulp or corrugated fiberboard for affordability.
Often sourced from nearby paper mills using waste paper, cut to custom sizes--it's a disposable, one-time-use item for cost efficiency.
