Technical Description
The ERICHSEN Cupping Test Deep-drawing Cup Test Machine, Model 212, is a fully automatic machine designed for testing the ductility of coated, ferrous, and non-ferrous metals. It features an electro-hydraulic drive, programmable logic control, and a data evaluation system. The machine is operated via a resistive touch panel with user-friendly menu navigation and includes main and emergency off switches.

Specifications
- Maximum drawing force: 120 kN
- Blank holding force: 45 kN
- Drawing punch stroke: 60 mm
- Blanking force: 200 kN
- Power supply: 3L/N/PE AC 400 V 50 Hz, 2.2 kW
- Dimensions: Height 1100 mm, Width 900 mm, Depth 800 mm
- Weight: 470 kg

Application
The machine is suitable for conducting cupping and deep-drawing cup tests on sheet metal with thicknesses ranging from 0.1 mm to 3.0 mm. It is particularly useful for quality assurance in manufacturing processes to ensure surface coatings remain defect-free, preventing corrosion.

Purpose
The machine aids in lowering reject rates by monitoring coating quality, sorting out lower quality materials, and ensuring high accuracy of test results with minimal maintenance.

Description
The machine's solid housing integrates the test aggregate, and all components are easily accessible for quick tool changes. The testing sequence is designed for efficiency, executing cutting, drawing, and ejecting in one operation.

Accessories (Optional)
- Data logger for recording measurements
- Bead Test Instrument, Model 227
- Special Microscope for test evaluation
- Various test tools

Selection Tables
Tables are provided for selecting drawing dies and blanking tools based on material type and thickness, with norms specified for ferritic and non-ferritic materials, as well as aluminum and aluminum alloys.
