Brass Spiked Perforating Pin Roller / Micro Perforation Needle Roller for Plastic Film

This industrial brass perforating pin roller is the core punching component for micro-perforation converting equipment, designed to create consistent tiny breathable holes on flexible substrates.

The roller barrel is crafted from precision machined polished H62 brass alloy, pre-drilled and locked with thousands of quenched high-carbon steel needles arranged in a dense staggered diagonal layout. Each spike maintains high hardness and sharpness, producing burr-free neat perforations without damaging thin film or fabric at high production speeds.

Brass features superior heat transfer performance; internal heating channels can be added upon request for thermal hot perforation, generating smoother hole edges for premium packaging products. The entire roller undergoes dynamic balance testing to eliminate rotational vibration, extending both roller and machine service life.

• Sharp, heat-treated steel needles (HRC 50) ensure clean, burr-free perforations
• Customizable needle density, length, angle, and spacing to match your exact hole pattern requirements

• Robust aluminum or stainless steel core for long service life in continuous operation
• Wear-resistant materials withstand high speeds, repeated use, and both cold/hot perforation processes

• Fits seamlessly into slitter machines, extruders, printing presses, and converting lines
• Suitable for a wide range of substrates: PE, PP, BOPP films, non-woven fabrics, paper, and leather

• OEM/ODM service available: custom roller diameter, length, shaft size, and needle configurations
• Available for both cold perforation (room temperature) and hot perforation (heated needle) applications

• Precision assembly reduces downtime and maintenance needs
• Designed for extended use, lowering long-term production costs

• Plastic Film Processing: Breathable perforation for fresh wrap, agricultural mulch film, POF shrink film, fruit & vegetable packaging film
• Non-woven Fabric Production: Vent hole punching for hygiene non-woven, geotextile, air filter cloth
• Packaging Industry: Micro holes for bakery bags, flower wrapping film, breathable composite packaging
• Leather & Composite Materials: Pore punching for synthetic leather, PU leather, aluminum foil paper

The perforating needle roller is installed in a converting or processing machine, where it rotates in contact with the substrate. The sharp, evenly spaced needles pierce the material as it passes through, creating consistent, uniform holes.

• Cold Perforation: Needles pierce the material at room temperature, ideal for thin films and paper.
• Hot Perforation: Heated needles melt clean holes in heat-sensitive materials like plastic films, preventing tearing and fraying.

• Custom Manufacturing: We design and build needle rollers to your exact specifications, from small prototypes to large production runs.
• Quality Control: Every roller undergoes precision testing for needle alignment, hardness, and balance before delivery.
• Fast Lead Times: Standard models ship within 7-15 days; custom orders take 15-30 days based on complexity.
• Expert Support: Our engineering team provides one-on-one consultation to help you select the right configuration for your application.
• Global Shipping: We offer reliable shipping to Australia, the US, Europe, and other regions with full documentation for customs clearance.
