Brass Perforating Hot Punching Pin Roller for Film Nonwoven & Plastic Micro-Perforation
Product Description of Industrial Perforating Needle Roller
This precision-engineered brass perforating pin roller is designed for industrial micro-perforation, offering consistent, clean holes for films, nonwovens, textiles, and packaging materials. Crafted from durable brass with high-strength steel pins, it ensures long-term wear resistance, anti-corrosion performance, and stable operation in high-speed production lines.
With CNC-drilled pin holes and customizable pin density, pitch, and angle, our pin rollers deliver uniform perforation results for applications including breathable packaging, agricultural films, battery separators, and synthetic leather processing. The brass body provides excellent thermal conductivity, making it suitable for both cold and heated perforation processes.
As a direct manufacturer, we offer full OEM/ODM customization to match your exact requirements for size, pin specifications, and mounting. Backed by strict quality control and fast lead times, these rollers are ideal for film converting, textile opening, and other industrial perforation needs.

How It Works
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.
