Overview
Cometech QC-603A / QC-603C Pneumatic Specimen Punch machines are designed for rapid cutting of standard test specimens using various interchangeable cutters.
QC-603A is pneumatically driven and optimized for soft materials such as rubber, soft plastics, leather and paper, while QC-603C adds an air‑hydraulic conversion system to significantly increase output for rigid plastics, fabrics and thick, tough specimens.
Both models can be used for specimen cutting and lamination, providing a compact, easy‑to‑operate solution for preparing samples for tensile, tear, elongation and other mechanical tests.

Key features & safety
- Pneumatic drive with **dual safety switches** to reduce operator risk during cutting.
- Higher-output QC-603C air‑hydraulic system enables cutting of harder plastics, fabrics and thick, resilient specimens.
- Designed for power-saving and time-saving operation, with compact, bench‑top structure and user‑friendly controls.
- Capable of both specimen cutting and lamination, supporting a wide range of lab workflows.
Cutters & configuration (optional)
- Cutter types (optional, sizes customizable):
- Thick cutter: folded sheet metal blade with reinforced walls for durable cutting of tough materials (e.g., fabric, leather).
- Thin cutter: laser‑cut for enhanced dimensional accuracy, suited for slicing softer materials.
- Precision cutter: heat‑treated and ground for superior strength and high-accuracy precision cutting.
- Additional precise cutter shapes can be provided based on customer‑specified specimen geometry.
Optional accessories
- CE protective cover: encloses the cutting area and includes a sensing mechanism so the press cannot operate when the cover is not securely closed; complies with EU CE safety standards.
- Pressure time delay valve: controls timing of pressure application to protect the cutter edge and reduce risk of specimen damage.
