Tensile Testing Sample Cutter YLCK-25

Overview

The PW YLCK-25 Tensile Testing Sample Cutter is a precision mechanical die-cutting instrument engineered for standardized specimen preparation in mechanical property testing of thin flexible materials. Designed in strict accordance with ASTM D882 (Standard Test Method for Tensile Properties of Thin Plastic Sheeting), ISO 527-3 (Plastics — Determination of Tensile Properties — Part 3: Test Conditions for Films and Sheets), and GB/T 1040.3 (Chinese national standard for tensile testing of plastics), this cutter ensures geometric consistency across specimens prior to tensile, peel, or heat seal strength evaluation. Its operation relies on a manually actuated lever mechanism coupled with hardened steel cutting dies, delivering repeatable, burr-free edges without thermal or shear-induced material deformation—critical for eliminating edge-initiated failure artifacts during uniaxial loading in universal testing machines.

Key Features

• Monolithic hardened tool-steel construction (HRC 58–62) for long-term dimensional stability and resistance to die wear under repeated use.
• Modular die assembly enabling rapid replacement or customization of sample width (standard 25 mm; optional widths include 10, 15, 50, and 100 mm upon request).
• Integrated depth-limiting stop and parallel anvil surface ensuring uniform compression force distribution across the full cutting area—minimizing thickness-dependent variation in cut quality.
• Ergonomic two-hand lever design compliant with ISO 13857 (safety distances to prevent hazard zones), reducing operator fatigue during high-volume sample preparation.
• No electrical or pneumatic components: fully mechanical operation eliminates dependency on external utilities and supports use in ISO Class 7 cleanrooms or explosion-proof environments where electromagnetic interference or compressed air infrastructure is restricted.

Sample Compatibility & Compliance

The YLCK-25 accommodates a broad range of polymeric and fibrous sheet materials including biaxially oriented polypropylene (BOPP), polyester (PET), polyethylene (PE), aluminum-laminated films, kraft paper, coated cardboard substrates, and medical-grade nonwovens. All specimens are constrained to a maximum thickness of 300 µm to maintain die clearance integrity and avoid incomplete shearing. Each cut produces ten identical specimens per stroke (single-layer configuration), aligned to ISO 291 (standard atmospheres for conditioning and testing) requirements when used in conjunction with controlled-environment sample storage. The device itself bears no CE or UL marking, as it falls outside the scope of EU Machinery Directive 2006/42/EC for non-powered equipment; however, its geometry and output conform to the specimen dimensional tolerances specified in ASTM D882 (±0.2 mm width tolerance) and ISO 527-3 (±0.5 mm length tolerance).

Software & Data Management

As a purely mechanical sample preparation tool, the YLCK-25 does not incorporate embedded electronics, firmware, or data logging capabilities. It requires no software installation, network connectivity, or calibration certificate renewal. Specimen traceability is maintained externally via laboratory information management systems (LIMS) or paper-based batch logs—consistent with GLP-compliant workflows where manual instrumentation is validated through documented operational qualification (OQ) protocols. Users may integrate serial-numbered die sets into asset tracking databases to support audit readiness for FDA 21 CFR Part 11–aligned environments, provided handwritten or scanned records of cutter usage (date, operator ID, material lot, specimen count) are retained for minimum 2 years per ICH E6(R3) guidelines.

Applications

• Preparation of Type V dog-bone specimens for tensile modulus and elongation-at-break measurement per ASTM D882 and ISO 527-3.
• Generation of standardized strips for 180° peel testing (ASTM D903, ISO 8510-2) on adhesive laminates and pressure-sensitive tapes.
• Cutting of uniform rectangles for heat seal strength analysis (ASTM F2054, ISO 11607-2) in sterile barrier system validation.
• Production of consistent blanks for puncture resistance (ASTM F1306) and tear propagation (ASTM D1922) assays.
• Quality control sampling in packaging converter facilities operating under ISO 9001:2015-certified quality management systems.

FAQ

Is the YLCK-25 compatible with ASTM D882 specimen geometry requirements?
Yes—the standard 25 mm × 210 mm cut meets the nominal dimensions and tolerance allowances defined in Section 7.2 of ASTM D882 for Type V specimens.
Can the cutter handle multi-layer laminates?
It is rated for single-layer materials up to 300 µm total thickness. Multi-layer structures must be verified for interlayer cohesion; delamination during cutting indicates insufficient bond strength and warrants process review.
Does the device require periodic recalibration?
No—mechanical die cutters are validated via physical verification of specimen dimensions using certified calipers (e.g., Mitutoyo IP67-rated digital micrometers) at start-up, after die replacement, and per shift in regulated environments.
What maintenance is recommended?
Monthly application of light mineral oil to the pivot pin and die interface; annual inspection of anvil flatness (≤0.02 mm deviation over 100 mm) using optical flats and monochromatic light interferometry.
Is technical documentation available in English?
Yes—complete user manual, dimensional drawings, and OQ test templates are supplied in English PDF format upon order confirmation.
