Product Specifications

Pneumatic Type Hole Puncher Customized Shape Punching Tool for Plastic Film

Product Overview

It features a C-frame structure and a 50mm material passing slot, incorporating an aerospace-grade aluminum alloy die base, Japanese HAP5R high-speed steel tooling, and an AirTAC cylinder. It offers a maximum punching speed of 260 CPM and a machining precision of 0.001mm, with an estimated service life of 18 to 20 million cycles. It is suitable for flexible packaging materials such as plastic films, laminated films, aluminum foil film, paper-plastic, paper, and non-woven fabrics.

Key Advantages

High-Precision Reproduction

Engineers independently perform modeling and programming based on client CAD drawings, PDF specifications. Utilizing integrated CNC precision mold-making, they achieve a 1:1 accurate reproduction of complex hole geometries—including curves, sharp angles, rounded corners, and contours—while strictly controlling dimensional tolerances to within 0.001 mm, thereby completely resolving issues such as deformation, distortion, and asymmetry in complex hole shapes.

Optimized cutting edge for flawless cuts

For irregular hole shapes, we have uniquely optimized the cutting edge layout and punching angles to balance the uneven forces encountered during non-standard cutting. Whether dealing with sharp corners, arcs, or complex polygonal structures, the process delivers clean, vertical cuts—resulting in smooth edges free from burrs, stress whitening, or tearing. This eliminates the need for manual trimming, significantly enhancing both the quality of custom packaging and the product yield rate.

Compatible with various types of flexible packaging

It is compatible with a wide range of materials—including thin films, thick films, multi-layer composites, aluminum-plastic laminates, paper, and non-woven fabrics—delivering clean, precise shaped punching results for both soft and rigid materials; its application versatility far exceeds that of standard industry shaped molds.

Flexible Customization + Rapid Delivery

We support fully customizable, non-standard, and complex-shaped designs without limitations on hole patterns, dimensions, or structural configurations. Our capabilities meet the personalized perforation needs for niche, high-end cultural/creative, and differentiated custom packaging. Leveraging our in-house R&D and manufacturing strengths, we offer short lead times, helping clients rapidly capture the custom packaging market.

Customization Process

Customer provides drawings or samples of the irregular-shaped holes, material specifications, and equipment installation details.
Custom drawings are created based on confirmed requirements, followed by discussions regarding configuration, pricing, and lead times.
Production is scheduled once the customer confirms the drawings and order.
4. Trial punching is performed using the confirmed materials to inspect the profile, dimensions, and cut quality.
5. A test video is provided for customer approval prior to shipment; packaging and dispatch are arranged upon confirmation.
