LDS electronic tensile testing machine

1、 Product introduction:

LDS type LCD electronic tensile testing machine is designed for universities and scientific research institutes. The design of the main engine and auxiliary equipment of the testing machine integrates the advanced technology of our company, with beautiful appearance, convenient operation and stable and reliable performance. The system controls the rotation of servo motor through the speed control system through the star controller. After the deceleration system decelerates, the precision lead screw vice belt crossbeam rises and descends to complete the tensile mechanical property test of the sample. It has no pollution, low noise, high efficiency and wide speed range.

The machine is widely used in spring production, building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastic, textile, home appliances and other industries.
