Product Overview

The KR‑414 manual ring‑crush specimen cutter is essential sample‑prep auxiliary hardware for Ring‑Crush Test (RCT), CMT corrugating‑medium flat‑crush and tensile‑strength testing of paper and paper‑board. By means of lever‑driven die‑cutting, it punches out standard‑dimension long‑strip test specimens with clean burr‑free edges. Consistent specimen geometry eliminates dimensional errors caused by manual scissor‑cutting, laying a solid foundation for reliable, repeatable compression‑strength and tensile‑strength test‑results.

Designed in compliance with TAPPI‑T409 and JIS‑P8113 standards, this bench‑top die‑cutter is widely adopted by paper‑making mills, corrugated‑carton manufacturers, packaging‑R&D centres and accredited third‑party testing labs for daily QC‑sample preparation. Multiple optional jigs and cutters can be matched to expand sample‑making capabilities for different paper‑board performance‑tests.

Core Product Competitive Advantages

1. High‑Precision Hardened Cutting‑Die Assembly Precision‑ground matched upper‑lower cutting dies guarantee strict long‑edge parallelism below 0.015 mm. Die‑cut edges are sharp and wear‑resistant, producing smooth, chip‑free specimen edges, avoiding fracture‑defects during subsequent RCT / tensile testing.
2. Two Standard Specimen‑Size Outputs for Multi‑Test Scenarios ‑ Size‑A: 152 × 12.7 mm, dedicated for ring‑crush RCT test specimens ‑ Size‑B: 200‑250 × 15 mm, applicable for paper tensile‑strength test‑pieces One machine covers two mainstream sample‑size requirements for paper‑lab routine‑work.
3. Lab‑Friendly Lever‑Press Manual‑Driven Operation Ergonomic long‑lever labour‑saving mechanism. Operators only need one‑hand pressing motion to complete die‑cutting. Built‑in spring‑buffered support structure cushions impact force during cutting stroke. No power source required; can be deployed anywhere on laboratory work‑benches.
4. Broad Specimen‑Thickness Compatibility & Robust Mechanical Build Handles raw‑material thickness from 0.1 mm up to 1.0 mm, covering most printing‑paper, liner‑board and corrugating‑medium grades. Heavy‑duty all‑metal frame structure delivers long‑term stability for high‑frequency batch‑sample‑cutting.
5. Rich Optional Auxiliary‑Fixture Ecosystem Compatible with multiple optional accessories: PAT‑ECT sample cutter, CMT‑CCT clamping jig, ring‑crush centre‑disc set, butterfly‑sample cutter and butterfly‑sample jig. Users can build a complete paper‑test sample‑preparation workstation according to laboratory‑project‑needs.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Set cutter on level rigid lab bench. Inspect cutting‑die surface for paper‑dust or nick‑damage. Place original paper / board sheet flat onto the cutter base platform.
2. Position Raw‑Material Align target sampling area precisely underneath the die‑cut cavity, keep sheet flat without wrinkles or offset.
3. Lever‑Actuated Die‑Cutting Firmly press down the operating lever until full die‑penetration is completed, then release lever to let it spring‑return to standby‑position.
4. Retrieve Qualified Specimen Take out punched long‑strip specimen. Inspect cutting edges for burrs, incomplete cuts or distortion. Discard defective samples and repeat cutting if required. Prepared specimens can be directly used for ring‑crush, tensile or other standard‑lab tests.
5. Post‑Operation Tidying Clear paper‑chip residues from cutting‑die and base‑platform. Protect sharp die‑edges from collision. Store the instrument in dry environment. Periodically inspect sharpness of cutting‑dies and replace worn die components.
