Custom Industrial Perforating Needle Roller with Adjustable Needle Density for High-Speed Hot/Cold Perforation
Our precision-engineered perforating needle rollers (also known as pinned rollers or spiked rollers) are designed to create clean, uniform micro-perforations on plastic films, flexible packaging, agricultural mulch films, textiles, and other substrates. Built with a high-strength metal core and hardened steel needles, these rollers deliver consistent performance in high-speed production lines, improving breathability, tearability, and product functionality.
- 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

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.
