Standard and method of testing for plastic tensile testing machine

The plastic tensile testing machine is designed to determine a variety of mechanical properties of both metallic and non-metallic materials. For non-metallic materials, it can measure maximum strength, elastic modulus (E), constant compressive strength, constant load elongation, yield strength, and other related parameters. For metallic materials, the machine can evaluate yield strength, non-proportional strength, total compressive strength, tensile strength, and elongation, providing essential data for material performance analysis. The test standard followed by the plastic tensile testing machine is GB/T 9341-2000, which outlines detailed procedures for conducting tensile tests on plastics. This standard is widely used in industry and research to ensure consistency and accuracy in material testing. In addition to tensile testing, the bending test is an important method for evaluating how materials perform under bending loads. It is commonly used in production to assess the bending strength and ductility of materials, serving as a critical reference for quality control and product design. GB/T 9341-2000 also provides comprehensive guidelines for conducting these bending tests, ensuring that results are reliable and comparable across different laboratories and applications. This test method is applicable to a wide range of materials, including thermoplastic molded and extruded products, such as filled or unfilled rigid thermoplastic sheets. It also covers thermoset molded sheets, including reinforced and laminated materials. Additionally, it applies to fiber-reinforced composites made from thermosetting or thermoplastic polymers, whether unidirectional or randomly oriented, including materials like woven roving, chopped strands, and hybrid reinforcements. The configuration of the plastic tensile testing machine includes several key components. The sample preparation instrument is used to create standard samples according to required dimensions. The main unit of the testing machine is the HY-0580 desktop electronic universal testing machine, known for its precision and versatility. The testing accessories include a three-point bending setup, which is ideal for evaluating rigid and semi-rigid materials. When selecting the appropriate fixture, it is crucial to consider the sample size and thickness, as the support span directly affects the test results. Different standards may require different indenter and base sizes, so it's recommended to consult the relevant specifications when setting up the test. During a three-point bending test, it is not advisable to measure deflection using beam displacement. Instead, a linear encoder or resistance strain gauge is used to directly measure the deformation and strain, ensuring more accurate and reliable results.

Tamping Rammer

Tamping rammer:it is made according to the principle of two-stroke internal combustion engine, and there are two pistons in the cylinder, the upper piston is the internal combustion piston, and the lower piston is the buffer piston. The lower part of the cylinder is equipped with a rammer that slopes the bottom surface, so that the vertical axis of the cylinder is skewed forward. The upper piston rod stretches out from the through hole in the middle of the cylinder top cover, and the lower piston rod stretches out from the lower end face of the cylinder, and is integrated with the rammer, and the cylinder and the rammer are tightened by a spring, and a handrail is provided to control the forward direction of the rammer. The fire rammer is under the action of the ignition and explosion force of the combustible mixture, therefore, it jumps off the ground in front of the top and under the action of its own weight, and falls to the ground to ram the soil, and the rammer jumps and falls, and the fuselage moves forward step by step. The rammer product has a wide range of uses, not only suitable for tamping and leveling with various sand, gravel and triple soil, but also suitable for tamping and leveling asphalt gravel, concrete and clay, especially suitable for the construction of buildings, ground, courtyards, roadbeds, bridge piles, trenches, fields, narrow sites and other environments.
