Overview
The Erichsen CP2000 Cupping Tester is a precision-engineered mechanical deformation instrument designed to quantitatively assess the ductility, formability, and coating adhesion performance of metallic sheets and coated substrates. Based on the classical Erichsen cupping test principle—where a hemispherical punch vertically deforms a clamped flat specimen until the onset of through-thickness cracking or coating failure—the CP2000 delivers repeatable, standardized measurements in accordance with ISO 1520:2022, EN ISO 20482, and ASTM D4145 (for coated metal panels). Its robust mechanical architecture eliminates electronic actuation variables, ensuring long-term metrological stability and minimal operator-induced variability. The instrument operates exclusively via manual rotary handle input, translating human torque into precisely controlled, linear displacement of the punch—enabling direct correlation between applied force and cup depth without sensor calibration drift.
Key Features
- Compliance with ISO 1520:2022 for standardized cupping depth measurement under defined clamping force (10 kN nominal) and punch geometry (φ20 mm hemispherical tip)
- Digital depth indicator with 0.01 mm resolution and dual-unit display (mm/inch), traceable to national metrology standards
- Manually operated rotary handle mechanism engineered for consistent loading rate and high inter-test reproducibility (RSD < 1.2% across 10 replicate tests on CR3 steel)
- Integrated high-intensity LED-illuminated magnifier (5× optical magnification) facilitating unambiguous visual detection of first crack, edge splitting, or coating delamination
- Ergonomic, quick-release clamping system with tactile feedback handles—enabling sub-30-second specimen changeover without tools or realignment
- Stainless-steel frame with vibration-damped base plate, certified for stable operation on standard laboratory workbenches (no dedicated anti-vibration table required)
Sample Compatibility & Compliance
The CP2000 accommodates flat sheet specimens measuring 70 × 70 mm minimum, with thicknesses ranging from 0.1 mm to 2.0 mm—including cold-rolled steel, aluminum alloys (e.g., AA1050, AA3003), galvanized steel, and pre-painted metal coils. It supports both bare metal evaluation (e.g., deep-drawing grade validation per EN 10131) and coated systems (coil-coated, powder-coated, or electrodeposited finishes). All test procedures align with quality assurance frameworks mandated by automotive OEMs (e.g., VW TL 226, GMW 14872) and global regulatory protocols requiring documented mechanical integrity verification. The device itself carries CE marking and conforms to EN ISO 12100:2019 (safety of machinery) and EN 61326-1:2013 (EMC compliance for laboratory equipment).
Software & Data Management
As a purely mechanical analog instrument, the CP2000 does not incorporate embedded software or digital data logging. This design philosophy prioritizes operational transparency, audit readiness, and immunity to firmware obsolescence or cybersecurity vulnerabilities. Test results—cupping depth values—are manually recorded in laboratory notebooks or integrated into LIMS/QMS platforms (e.g., LabWare, TrackWise) via structured CSV templates provided in the user documentation. Full traceability is maintained through serialized instrument identification, calibration certificate (issued annually per ISO/IEC 17025-accredited provider), and GLP-compliant test record templates supporting FDA 21 CFR Part 11–aligned signature workflows when used in regulated environments.
Applications
- Quality control of incoming coil stock in appliance and automotive body panel manufacturing
- Validation of pretreatment and curing parameters in coil coating lines (e.g., chromate vs. zirconium-based conversion coatings)
- Comparative assessment of coating flexibility across supplier batches per ISO 2409 cross-cut or ISO 6272 impact testing correlation studies
- R&D evaluation of novel alloy compositions for stamping feasibility prior to die tryout
- Third-party certification testing for EN 10169 (continuously hot-dip galvanized steel) and EN 10168 (technical delivery conditions)
FAQ
Does the CP2000 require electrical power or compressed air?
No. It is a fully manual, mechanically actuated tester requiring only human input via the rotary handle.
Is calibration certification included with purchase?
Yes—a factory-issued calibration report traceable to NMI Netherlands (VSL) is supplied, with recommendations for annual recalibration per ISO/IEC 17025 requirements.
Can the CP2000 be used for non-metallic substrates such as plastic laminates?
Not per ISO 1520. While empirical use occurs in some R&D labs, official compliance and published correlations apply solely to metallic sheet materials.
What maintenance is required?
Monthly cleaning of the punch and die surfaces with isopropyl alcohol; annual lubrication of the lead screw and bearing assembly using ISO VG 68 mineral oil—detailed in Section 7.2 of the Operation Manual.
Is technical support available outside business hours?
Yes. Priority remote diagnostics and application consultation are offered 24/7 to contract-support customers in EMEA and North America regions.
