Overview
The ERICHSEN 202EM Motorized Cupping Tester is a precision-engineered benchtop instrument designed for standardized evaluation of ductility and adhesion performance of organic coatings on metallic substrates. Based on the cupping (Erichsen) test principle—where a hemispherical punch deforms a clamped coated sheet until coating fracture occurs—the device quantifies deformation resistance via the cupping depth (in mm), measured at the point of first visible crack under controlled mechanical loading. This method complies strictly with DIN EN ISO 1520, BS 3900-E4, NF T 30-019, and SIS 18 41 77, making it indispensable for quality assurance in R&D laboratories, paint formulation houses, and industrial finishing lines. The 202EM integrates a rigid steel frame, side-access test head geometry accommodating large-format specimens (up to 150 × 150 mm), and fully motorized actuation with programmable stroke and speed control—ensuring high repeatability across operator shifts and production batches.
Key Features
- Motor-driven hemispherical punch actuation with continuous speed adjustment from 2 to 60 mm/min, enabling precise strain-rate control per ASTM D4145 and ISO 1520 requirements.
- Side-opening test head design facilitates rapid specimen loading and accommodates substrates up to 1.5 mm thickness without repositioning.
- Integrated touch-screen HMI with password-protected parameter configuration (e.g., preset stroke, test speed, dwell time) to prevent unauthorized modification and ensure audit-ready procedural consistency.
- Digital displacement readout with 0.1 mm resolution, directly displaying real-time cupping depth during deformation.
- Automated hydraulic clamping system ensures uniform edge pressure distribution across the specimen, minimizing slippage and improving inter-laboratory reproducibility.
- Modular optical integration: Dedicated microscope mounting interface compatible with analog or digital microscopes (e.g., ERICHSEN 456-USB), synchronized with punch motion to maintain focus throughout testing.
Sample Compatibility & Compliance
The 202EM supports flat metallic substrates—including cold-rolled steel, aluminum alloys, and galvanized sheets—with thicknesses ranging from 0.1 mm to 1.5 mm. Standard test dies (e.g., No. 27 die with 20 mm punch diameter and 27 mm die cavity) conform to EN ISO 20482 for wider sample widths (30–55 mm). Optional dies (No. 11, 8 mm punch) enable compliance with specialized specifications for thin-gauge materials. All test procedures align with GLP-compliant documentation workflows; data export functionality supports traceability required under ISO/IEC 17025 accreditation and FDA 21 CFR Part 11–aligned electronic record systems when paired with validated software modules.
Software & Data Management
While the base 202EM operates via embedded firmware with local touch-screen control, optional digital microscopy (Model 456-USB) enables full digitization of test outcomes. Equipped with a 2 MP CMOS sensor, adjustable white LED illumination, and calibrated micrometric scale overlay, the 456-USB captures high-fidelity still images and time-synchronized video recordings of crack initiation and propagation. Captured media are timestamped and stored in standard JPEG/AVI formats, facilitating comparative analysis, report generation, and long-term archive retention. The ring adapter (Order No. 0872.01.32), magnetically secured to the instrument frame, guarantees zero parallax drift during dynamic observation—eliminating manual refocusing mid-test.
Applications
This tester serves critical functions across coating development and manufacturing validation: assessing film-forming behavior of waterborne and solvent-based automotive primers; verifying batch-to-batch consistency of coil-coating systems; evaluating bending resistance of powder-coated architectural panels; screening corrosion-inhibiting pretreatments prior to electrocoating; and supporting failure analysis in field return investigations. Its quantitative output—cupping depth—is directly correlated to post-forming coating integrity, providing predictive insight into real-world performance under deep-drawing, roll-forming, or impact stress conditions.
FAQ
Is the 202EM compliant with ISO/IEC 17025 calibration requirements?
Yes—the instrument’s displacement transducer and speed controller are factory-calibrated against NIST-traceable standards; calibration certificates and uncertainty budgets are available upon request.
Can the microscope be retrofitted after initial purchase?
No—optical integration requires factory-installed mechanical interfaces and firmware synchronization; microscope packages must be ordered concurrently with the main unit.
What electrical specifications are supported beyond 230 V / 50 Hz?
Custom power modules supporting 115 V / 60 Hz, 200–240 V / 50/60 Hz, or 3-phase configurations are available as OEM options.
Does the 202EM support automated data logging to external LIMS or MES platforms?
Via optional RS-232 or Ethernet interface modules (not included standard), raw stroke/time data can be streamed in ASCII format for integration with third-party laboratory informatics systems.
Are replacement dies certified to EN ISO 20482 dimensional tolerances?
All ERICHSEN-certified dies undergo metrological verification using coordinate measuring machines (CMM); certificates of conformance accompany each shipment.
