TianYuan TY-5001 Manual Notching Machine for Impact Testing Specimens

Overview

The TianYuan TY-5001 Manual Notching Machine is a precision-engineered specimen preparation instrument designed exclusively for producing standardized notches in rigid plastic and non-metallic materials prior to Charpy (simply supported beam) and Izod (cantilever beam) impact testing. It operates on a manually actuated mechanical feed system, ensuring consistent, repeatable notch geometry without reliance on electrical or pneumatic subsystems—making it ideal for laboratories requiring robustness, operational transparency, and minimal maintenance overhead. The machine conforms strictly to the dimensional, angular, and radius tolerances specified in ISO 179-1:2010 (Plastics — Determination of Charpy impact properties), ISO 180:2013 (Plastics — Determination of Izod impact strength), GB/T 1043.1–2018 (Chinese national standard for Charpy impact testing), and GB/T 1843–2008 (Izod impact testing). Its mechanical architecture eliminates variability introduced by servo drift or software latency, delivering high reproducibility across successive notching cycles under ambient lab conditions.

Key Features

• Manually controlled feed mechanism with calibrated micrometer-style advancement for precise depth control and full operator visibility of each cutting stroke
• Dedicated interchangeable blade holders accommodating all standardized notch geometries: Type A (sharp, low-radius), Type B (moderate radius), and Type C variants (C1 for thin-section high-strength plastics, C2/C3 for specialized thickness-dependent configurations)
• Fixed 45°±1° blade alignment maintained via hardened steel guide bushings and precision-ground mounting surfaces, minimizing angular deviation over extended service life
• Blade stroke of 24 mm ensures full engagement across standard specimen widths (up to 12.7 mm per ASTM D6110 / ISO 179), while 10 mm total feed travel accommodates multi-pass profiling where required
• Consistent 0.5 mm feed increment per manual stroke enables fine-tuned control over notch depth—critical for brittle thermoplastics where overcutting induces microcracking or premature failure
• Tool-free blade change system with positive-lock retention, reducing setup time between test series and supporting rapid reconfiguration for multi-standard compliance workflows

Sample Compatibility & Compliance

The TY-5001 supports rectangular bar specimens conforming to ISO 179 and ISO 180 dimensions (e.g., 80 × 10 × 4 mm, 120 × 15 × 10 mm), including Type 1 (10 mm wide), Type 2 (15 mm wide), and Type 3 (20 mm wide) geometries. It accepts both machined and injection-molded plaques with surface flatness ≤ 0.1 mm over 100 mm length. All notch profiles meet the radii tolerances mandated by ISO/IEC 17025-accredited impact testing protocols. The machine itself carries no CE marking but is constructed to meet mechanical safety requirements outlined in ISO 12100:2010 (Safety of machinery — General principles for design). Documentation includes traceable calibration records for blade angle and radius verification using certified optical profilometry (NIST-traceable reference standards available upon request).

Software & Data Management

As a fully manual, non-electronic device, the TY-5001 does not incorporate embedded firmware, data logging, or connectivity features. This design choice aligns with GLP (Good Laboratory Practice) environments where audit trails must originate from human-controlled procedural documentation—not automated systems requiring 21 CFR Part 11 validation. Laboratories integrate the TY-5001 into electronic lab notebooks (ELNs) or LIMS via standardized SOPs that record operator ID, specimen batch number, notch type selected, blade serial number, and visual inspection pass/fail status post-notching. Blade wear tracking is performed manually using calibrated radius gauges at defined intervals (e.g., every 50 specimens), with logs retained for ISO 17025 internal audits.

Applications

• Preparation of notched specimens for ISO 179 Charpy impact testing of ABS, PC, PA6, POM, and reinforced composites
• Generation of Izod-notched bars per ISO 180 for quality control in extrusion and injection molding facilities
• Research-grade specimen conditioning in polymer physics labs studying fracture initiation mechanisms under controlled notch root geometry
• Calibration verification of automated notching systems—serving as a reference baseline for comparative performance assessment
• Training platforms in university materials science laboratories due to transparent mechanical operation and direct tactile feedback during feed actuation

FAQ

Does the TY-5001 require electrical power or compressed air?

No—it is purely mechanical and operated via handwheel-driven feed; no external utilities are needed.
Can the TY-5001 produce ASTM D6110-compliant notches?

Yes—its Type A and Type B blades satisfy ASTM D6110’s 45°±1° angle and radius specifications when used with properly conditioned specimens.
What maintenance schedule is recommended for long-term accuracy?

Blade sharpening every 200–300 notches (depending on material abrasiveness); annual verification of guide rail parallelism and angular fixture repeatability using optical alignment tools.
Is NIST-traceable calibration documentation available?

Yes—upon order, TianYuan provides a Certificate of Conformance with dimensional verification data for blade angle and tip radius, referenced to ISO 17025-accredited metrology labs.
Can custom notch profiles be accommodated?

Yes—custom blades may be fabricated per client drawings (e.g., modified angles, asymmetric radii, or stepped profiles), subject to minimum order quantities and lead time confirmation.
