Custom Pneumatic Oval Hole Puncher for Plastic Bag

Product Overview

The pneumatic oval hole punching machine is a specialized punching die for fully automated bag-making production lines, primarily used for processing oval holes in plastic films and flexible packaging. It utilizes an aviation-grade aluminum die base and imported Japanese high-speed steel blades, supporting high-speed, stable punching and clean, full-cut blanking. Solving production problems such as deformation, burrs, and short lifespan in large-diameter punching, and is suitable for mass production of standardized packaging.

Key Advantages

Japanese-imported HAP5R high-speed steel

The blade part are made of imported Japanese HAP5R high-speed steel, which is wear-resistant and has a long service life.

Aerospace-grade aluminum alloy

The aerospace-grade aluminum alloy mold base balances structural strength and heat dissipation performance, providing stable support for the entire puncher.

AirTAC Cylinder

AirTAC cylinders provide pneumatic punching power, enabling continuous action in conjunction with bag-making or packaging equipment.

Hole type and size can be customized

Other hole types and sizes can be evaluated based on customer drawings or samples.

Application

Material

Includes PE, PO, PP, OPP, PVC, PPE, PPU, CPE, LDPE plastic films, as well as flexible packaging materials such as aluminum foil composite films, paper-plastic composites, paper, and non-woven fabrics. The thickness, toughness, and number of layers of different materials will affect the tear resistance; for special materials, it is recommended to provide samples for testing.

Trial Operation and Routine Maintenance

After installation, first check the tool alignment, cylinder movement, guide condition, feed direction and cutting position at low speed.
Perform a small trial cut using the actual packaging material and confirm that the trimmed edge, rounded corner and packaging bag surface meet the requirements.
Increase the speed gradually while monitoring air-supply stability, film-feed synchronization and continuous cutting performance.
If burrs or film tearing occur, check in sequence whether the air pressure is insufficient or unstable, whether the cutting edge is worn or dull, whether the film feed is synchronized and whether the guide is misaligned.
Stop the machine and release the air pressure before adjusting, cleaning or inspecting the tool.
