Universal Testing Machine (UTM):
- Purpose: Measures mechanical properties such as tensile strength, elongation, and compression strength.
- How it works: Applies controlled tensile or compressive force to a plastic specimen until it fractures or deforms.
Melt Flow Index Tester:
- Purpose: Determines the melt flow rate of thermoplastics under specific conditions.
- How it works: Measures the flowability of molten plastic through a standardized orifice at a specified temperature and load.
Impact Testing Machine:
- Purpose: Evaluates the impact resistance of plastics.
- How it works: Drops a pendulum onto a notched or unnotched plastic specimen to measure its ability to absorb energy upon impact.
Thermal Analysis Instruments (e.g., Differential Scanning Calorimeter, Thermogravimetric Analyzer):
- Purpose: Analyzes the thermal properties of plastics, including melting point, crystallinity, and thermal stability.
- How they work: Measures changes in heat flow, weight, or other properties as a function of temperature.
Rheometer:
- Purpose: Studies the flow and deformation behavior of plastics under different conditions.
- How it works: Applies shear or oscillatory stress to a molten polymer to measure its viscosity, shear rate, and other rheological properties.
Hardness Tester:
- Purpose: Measures the hardness of plastics.
- How it works: Applies a known force to an indenter and measures the depth of penetration to determine hardness.
Oxygen Index Tester:
- Purpose: Determines the minimum concentration of oxygen that will support combustion of a plastic material.
- How it works: Measures the material's flammability by exposing it to controlled oxygen and nitrogen concentrations.
Environmental Testing Chamber:
- Purpose: Simulates environmental conditions such as temperature and humidity to assess the long-term stability of plastic materials.
- How it works: Exposes plastic specimens to controlled environmental conditions over time.

These testing machines are essential for ensuring that plastic materials meet specified standards and performance criteria. They help manufacturers and researchers understand the properties of plastics and make informed decisions about material selection for various applications.
