Plastic Testing Equipments

Exploring Plastic Testing Equipments for Comprehensive Material Evaluation

Plastic testing encompasses a variety of methods to characterize material properties such as tensile strength, flexibility, impact resistance, and chemical compatibility. Shijiazhuang Zhongshi Testing Machine Co., Ltd. presents a suite of plastic testing equipments to help manufacturers, research laboratories, and quality centers ensure that plastic products meet or exceed performance specifications.

Testing Capabilities

• Universal Testing Machines (UTM): Capable of tensile, compression, bending, and peeling tests with load capacities from 500 N to 100 kN. Modular grips accommodate films, sheets, fibers, and molded parts.

• Impact Testers: Charpy and Izod impact testers assess notch sensitivity and energy absorption characteristics under dynamic loading.

• Hardness Testers: Shore A, D, and Rockwell scales determine surface hardness, useful for rubber-modified plastics and rigid polymers.

• Thermal Analysis: Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) instruments measure melting point, crystallization behavior, and thermal degradation thresholds.

• Environmental Stress Cracking (ESC): Fixtures designed to expose plastic samples to chemicals, stress loads, and elevated temperatures to predict long-term durability.

Performance Metrics

• Tensile Strength: Up to 100 MPa, with elongation measurement to ±0.1 mm.

• Impact Energy: Range 0.1 J–10 J, with automated striker positioning.

• Thermal Resolution: 0.1 °C for DSC, 0.01 mg weight change sensitivity for TGA.

• Data Management: Centralized software for multi-test data aggregation, statistical analysis, and report customization.

Industries Served

• Packaging: Evaluating film puncture resistance, seal strength, and barrier properties.

• Automotive: Testing polypropylene bumpers, interior panels, and under-the-hood components under temperature and mechanical stress.

• Electronics: Validating insulating plastics, cable jackets, and connectors for tensile and thermal stability.

• Healthcare: Ensuring medical-grade plastics meet biocompatibility and sterilization requirements.
