Plastic tensile machine (desktop)

The plastic tensile machine (desktop) adopts a single space structure, with a space type of lower space, mainly composed of the host (including frame, base, transmission system), fixtures, deformation measurement system, software system, and electrical system.

Plastic tensile testing machine, also known as plastic tensile testing machine or plastic tensile strength testing machine, is a device used to test and analyze the mechanical properties of plastic materials under tensile force. This equipment is mainly used to measure the tensile strength, elongation, tear strength, compression strength and other parameters of various materials such as plastics, composite materials, flexible packaging materials, plastic films, fibers, etc. It is crucial for understanding and ensuring the quality and performance of materials.

Equipment Composition

Plastic tensile machines usually consist of the following main parts:

Loading system: including motor, transmission system, and loading device (such as fixture), used to apply tensile force to the specimen.

Measurement system: Measure the force and deformation of the specimen during the loading process through sensors such as strain gauges.

Control system: It can be a computer control system used to set test parameters (such as stretching speed, maximum force, etc.), collect and process test data.

Display system: Display the test results in numerical or graphical form for easy user reading.

Fixture: used to fix the specimen to ensure the accuracy and repeatability of the test. Different types and shapes of specimens require different fixtures.

working principle

During the tensile test, the specimen is fixed between two fixtures, with one fixture fixed in place and the other fixture moving at a certain speed through a loading system, gradually applying tensile force to the specimen. As the force increases, the specimen will deform until it fractures. Throughout the process, the measurement system will record real-time data on force and sample deformation, and the control system will generate test curves and results based on this data.

Plastic tensile machine (desktop)Structure and working principle:

This device adopts a single space structure, with a space type of lower space, mainly composed of a host (including rack, base, transmission system), fixtures, deformation measurement system, software system, and electrical system.

The computer system of this device controls the servo motor to rotate through a controller. After being decelerated by a reduction system, the precision screw pair drives the moving crossbeam to rise and fall, completing various mechanical performance tests such as tensile, compressive, and bending of the sample. High precision sensors are used to accurately control, measure, automatically display, and record the deformation of the load and specimen, as well as the displacement of the crossbeam. The program controls and processes the test results.
