Overview

This machine is designed and manufactured in accordance with the requirements of GB/T8814-2004 and GB/T11793-2008. It is mainly used to test the mechanical properties of unplasticized polyvinyl chloride (PVC-U) profiles for doors and windows, and to conduct fracture strength tests on the corner parts of doors and windows. It can measure the failure load and bending stress of the test specimens. The machine has a reasonable structure, a high degree of automation, and is simple and convenient to operate. It is an essential testing device for relevant manufacturers, quality inspection units, and research institutions.

Instrument Features

Ø It adopts an integrated mechanical and electrical design, consisting of a main unit and an electrical control box. The overall structure is advanced and reasonable, and it is convenient to use.；

Ø The single-chip microcomputer data acquisition system and high-precision load sensor have realized electronic measurement and digital display, making the data test accurate and the performance stable and reliable.；

Ø The uniquely designed pulley-type automatic adjustment mechanism enables the sample to self-align during the loading process, effectively eliminating the friction between the sample and the pad in the old model, making the testing method more scientific and the results more accurate.；

Ø It has an automatic printing function and can record the test results.
