What is a plastic strength testing machine?
In industrial production, scientific research experiments and quality inspection, plastic strength testing machine is a vital equipment. It is used to test the mechanical properties of plastic materials, such as tensile strength, flexural strength, compressive strength, etc., to ensure that the material meets relevant standards and application requirements. This article will introduce in detail the definition, working principle, application scenarios and recent hot topics of plastic strength testing machines.
1. Definition of plastic strength testing machine

Plastic strength testing machine is a device specially used to test the mechanical properties of plastic materials. It measures the strength, elastic modulus, elongation at break and other parameters of plastic materials by applying external forces (such as tension, compression, bending, etc.). This data is of great significance for materials research and development, quality control and application design.
2. Working principle of plastic strength testing machine
Plastic strength testing machines usually consist of three parts: loading system, control system and measurement system. The loading system is responsible for applying external force, the control system adjusts the loading speed and method, and the measurement system records the deformation and stress of the material. The following is a brief description of common test items:
| test items | Test method | Applicable standards |
|---|---|---|
| tensile strength | Apply axial tension to the sample until it breaks | ISO 527, ASTM D638 |
| Bending strength | Apply three or four point bending force to the sample | ISO 178, ASTM D790 |
| Compressive strength | Apply axial pressure to the sample until it deforms | ISO 604, ASTM D695 |
3. Application scenarios of plastic strength testing machine
Plastic strength testing machines are widely used in the following fields:
1.plastic manufacturing: Used to test the mechanical properties of raw materials and finished products to ensure product quality.
