Elastocon EP 02 Pneumatic Sample Cutter for Rubber and Plastic Testing

Overview

The Elastocon EP 02 is a compact, benchtop-mounted pneumatic sample cutter engineered specifically for standardized specimen preparation in rubber and plastic testing laboratories. Designed in accordance with ISO 527, ISO 37, ASTM D412, ASTM D624, and ISO 6892–1 requirements, the EP 02 delivers repeatable, high-precision cutting of dumbbell-shaped, ring, strip, and disk specimens from vulcanized rubber compounds, thermoplastic elastomers, polymeric films, and sheet materials. Its self-contained pneumatic actuation system eliminates dependency on external air compressors beyond standard shop air supply (6–8 bar), while its integrated rubber isolation base ensures stable operation without permanent mounting to laboratory furniture. The machine operates on the principle of controlled, high-force vertical die penetration—achieving consistent specimen geometry critical for tensile, tear, hardness, and compression testing compliance.

Key Features

• Pneumatic drive system delivering nominal 18 kN cutting force (up to 25 kN peak) for clean, burr-free cuts across filled and reinforced elastomers.
• Adjustable height mechanism (50 mm range) enabling precise alignment between cutting die and base plate—essential for maintaining uniform specimen thickness and edge integrity.
• Modular die compatibility: accommodates standard cutting dies with heights from 25 mm to 65 mm, supporting ISO, ASTM, and DIN-compliant geometries including Type 1A, Type 2, and Ring Tensile dies.
• Robust construction using anodized aluminum frames and galvanized steel structural components—resistant to corrosion and mechanical wear under routine lab use.
• Dual-hand safety interlock system requiring simultaneous activation of two push buttons to initiate stroke, compliant with EN ISO 13857 and EN 60204-1 machinery safety directives.
• Integrated emergency stop button located within immediate operator reach, wired directly to the pneumatic valve manifold for instantaneous pressure cutoff.
• Self-leveling rubber base isolates vibration and prevents slippage on smooth work surfaces—no bolts, clamps, or anchoring required.

Sample Compatibility & Compliance

The EP 02 is validated for processing raw and cured rubber sheets (NR, SBR, BR, EPDM, NBR), thermoplastic polyurethanes (TPU), silicone elastomers, PVC compounds, and polyolefin films up to 12 mm thickness. Specimen consistency is maintained via strict adherence to die clearance tolerances (±0.05 mm) and controlled dwell time during cutting. All operational parameters—including stroke depth, dwell duration, and pressure decay profiles—are traceable and reproducible across shifts and operators. The system supports GLP-compliant documentation when paired with Elastocon’s optional calibration logbook and die certification records. It meets essential requirements for ISO/IEC 17025-accredited testing laboratories performing material qualification per automotive (SAE J200), aerospace (AMS 3675), and medical device (ISO 10993-12) standards.

Software & Data Management

The EP 02 is a standalone mechanical instrument with no embedded firmware or digital interface. However, it integrates seamlessly into regulated quality environments through documented calibration procedures, preventive maintenance logs, and traceable die certification (provided with each cutting die). Users may record operational parameters—including date/time of use, die ID, material batch, operator ID, and observed cut quality—in paper-based or LIMS-linked electronic logs. For laboratories operating under FDA 21 CFR Part 11 or EU Annex 11 requirements, Elastocon supplies a full validation package—including IQ/OQ protocols, traceable pressure gauge calibration certificates, and mechanical performance verification reports—to support equipment qualification and audit readiness.

Applications

• Preparation of tensile test specimens (dumbbell, ring, and strip forms) per ISO 527-2, ASTM D412, and ISO 37.
• Cutting of tear test specimens (Trouser, Angle, and Crescent types) per ISO 34-1 and ASTM D624.
• Generation of compression set and hardness test disks (e.g., Shore A/D rounds) per ISO 816 and ASTM D2240.
• Production of specimens for dynamic mechanical analysis (DMA), fatigue testing, and aging studies where dimensional repeatability directly impacts data variance.
• Quality control in rubber compound development labs, tire manufacturing R&D centers, and polymer extrusion facilities requiring rapid turnaround of standardized samples.

FAQ

Is the EP 02 compatible with ISO 2781-compliant die sets?
Yes—the EP 02 accepts all standard ISO 2781 cutting dies with mounting heights between 25 mm and 65 mm, provided they feature a 200 × 200 mm base footprint.

Does the machine require compressed air conditioning (filter/regulator/lubricator)?
Yes—clean, dry, oil-free air at 6–8 bar is mandatory. A coalescing filter and pressure regulator are recommended upstream of the inlet port to ensure long-term valve reliability.

Can the EP 02 be used for cutting fiber-reinforced composites?
No—it is not designed for abrasive or highly filled composites containing >30% glass/carbon fiber; such materials risk premature die wear and inconsistent cut quality.

What is the recommended maintenance interval for the pneumatic cylinder seals?
Under typical lab usage (≤200 cuts/day), inspect and replace seals every 12 months or after 10,000 cycles—whichever occurs first—as documented in the Elastocon Maintenance Manual Rev. 4.2.

Is the EP 02 certified for CE marking?
Yes—the unit carries CE marking under the Machinery Directive 2006/42/EC and complies with harmonized standards EN ISO 12100, EN 60204-1, and EN ISO 13857.
