Product Overview

The KR‑415 flat‑crush circular sample cutter is dedicated auxiliary sample‑preparation hardware for corrugated‑board flat‑crush (FCT) testing. Working together with paper‑board compression strength testers, it precisely punches out perfectly‑dimensioned circular test specimens for flat‑crush resistance evaluation of corrugated fibre‑board. The prepared circular specimens are placed between compression platens to run standard flat‑crush tests, delivering valid baseline data for corrugated‑material quality‑control.

Built according to ISO 7263 international test‑specifications, this manual punch‑type sampler is widely used in corrugated‑board mills, packaging‑material factories, pulp‑paper R&D laboratories and third‑party inspection institutions for routine QC‑sample preparation. Two hardware grades (Model‑A and Model‑B) are available to satisfy different specimen‑area requirements.

Core Product Competitive Advantages

1. High‑Precision Circular Punching Blade Assembly Precision‑ground circular cutting blade ensures neat, burr‑free cut edges. It keeps specimen‑area tolerance within standard‑allowed range, eliminating dimensional deviation caused by manual scissors‑cutting, and guarantees consistency for subsequent flat‑crush test‑results.
2. Two‑Size‑Option Modular Design Two standard variants for selection: Model‑A for 38.5 cm² specimens and Model‑B for 100 cm² specimens. Users pick suitable version according to test‑standard requirements, covering most common FCT flat‑crush‑test scenarios in packaging‑industry laboratories.
3. Spring‑Assisted Manual‑Press Operation, Simple‑To‑Handle Ergonomic rotary‑press handle paired with built‑in spring‑return mechanism. Operators place sampler onto corrugated‑board sheet and rotate handle to complete punching within seconds. Four positioning spikes on bottom prevent slipping during cutting‑procedure, avoiding offset‑cutting defects. No power supply required, convenient for lab‑bench daily‑use.
4. Compact Portable Mechanical‑Body, Easy‑Maintenance Solid metal construction, light‑weight whole‑unit. Model‑A weighs only 1.5 kg and Model‑B is 3.5 kg. Small footprint occupies minimal bench‑top space. Blade‑replacement procedure is straightforward for regular wear‑part swap.
5. Perfect Matching With Compression‑Strength Testers Specimens produced by KR‑415 can be directly mounted on standard compression‑test platens, fully adapting to FCT flat‑crush test workflow. It forms a complete test‑solution together with paper‑board compression‑strength‑testing instruments.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place the sampler on flat, rigid cutting backing‑pad. Select A‑type or B‑type model according to applicable test‑standard. Lay corrugated‑board raw‑sheet flat beneath the cutter assembly.
2. Positioning & Punching Align sampler over target sampling zone. Let bottom positioning spikes bite into board surface to prevent shifting. Rotate top handle clockwise to drive circular blade through corrugated‑board until full penetration is achieved.
3. Retrieve Standard Circular Specimen Reverse‑rotate handle to lift cutting‑blade. Take‑out the finished circular FCT specimen, inspect cutting edge for burrs or incomplete cuts. Reject defective samples and re‑sample if necessary.
4. Subsequent Test‑Procedure Place qualified circular specimen onto compression‑tester platens, ready for formal flat‑crush resistance measurement.
5. Post‑Operation Tidying Clean blade and base to remove paper‑dust and corrugated‑chip residues. Store sampler in dry location to protect cutting‑edge from impact‑damage. Inspect blade sharpness periodically and replace worn cutting‑ring on schedule.
