Plastic Material Testing Equipments – From Fundamental Properties to Advanced Analysis

Plastics are the backbone of modern manufacturing, offering lightweight, corrosion-resistant, and cost-effective solutions. Yet, their performance depends heavily on material properties such as tensile strength, impact resistance, thermal behavior, and chemical compatibility. Shijiazhuang Zhongshi Testing Machine Co., Ltd. provides a full line of plastic material testing equipments to support R&D, quality assurance, and product certification efforts.

Essential Tests and Instruments

• Universal Testing: Tensile, compression, flexural, and shear tests are conducted on universal testing machines equipped with polymer-specific fixtures. These tests deliver modulus, yield strength, and elongation at break data per ASTM D638 and ISO 527.

• Impact Testing: Charpy and Izod testers measure the energy absorbed by notched plastic samples under sudden loading, following ASTM D256. Impact resistance is critical for applications subject to knocks or drops.

• Thermal Analysis: Differential Scanning Calorimetry (DSC) identifies glass transition, crystallization, and melting temperatures, guiding processing parameters. Thermogravimetric Analysis (TGA) quantifies thermal stability and degradation onset—essential for high-temperature applications.

• Hardness Testing: Rockwell, Shore, and Vickers hardness testers evaluate surface resistance for rigid and semi-rigid polymers.

• Chemical Resistance: Immersion baths expose plastic samples to acids, bases, solvents, or oils; subsequent dimensional and mechanical tests reveal susceptibility to swelling or stress-cracking.

Advanced Characterization
For specialized needs, we offer:

• Rheometry: Melt flow indexers and capillary rheometers quantify flow behavior, influencing extrusion and injection molding settings.

• Spectroscopic Analysis: FTIR attachments help identify polymer composition and potential contaminants.

• Environmental Stress Cracking: Custom rigs immerse stressed samples in chemical media at elevated temperatures, simulating decades of service in months.

Laboratory Integration and Software
Our equipment suite interfaces with centralized LIMS platforms, offering test scheduling, electronic work orders, and automated compliance reporting. Built-in statistical modules enable control charting and process capability studies—crucial for continuous improvement initiatives.

Industry Relevance
