The company is located in the western part of Taian, 5 kilometers west of Taian Station.

Since its establishment, our company has continuously innovated and developed, steadily advancing, and has successively passed the EU CE certification and ISO9001 quality system certification.,Products cover all over the country and are exported to countries such as South Korea, Japan, Malaysia, Vietnam, the Philippines, Myanmar, Thailand, Indonesia, Angola, Saudi Arabia, Congo, Spain, Germany, Austria, Peru, and the United States.

Electronic universalTensile testing machineThe choice of accessories has a significant impact on the normal use of the tensile machine. Currently, there are many related products on the market. When choosing accessories for the electronic universal tensile testing machine, users must select based on their actual situation. Generally speaking, when choosing electronic universalTensile testing machineaccessories, the following factors can be considered.

1. For ordinary metal and non-metal samples, the jaws of the fixture directly contact the sample, and high-quality alloy structural steel, alloy high carbon steel (or low carbon alloy steel), cold work tool steel, etc. are generally used, which are treated with appropriate heat treatment processes (quenching and tempering, carburizing quenching, etc.) to enhance their strength and wear resistance. Sometimes, special steel materials are also embedded at the jaw or the jaw surface is coated with gold sand.

2. If it is ordinary material, our fixtures are made of high-quality medium carbon steel and alloy structural steel, which are treated with appropriate heat treatment processes to enhance their mechanical properties. Sometimes, to reduce weight, aluminum alloys and other non-ferrous metals and special metals are also used. Sometimes forged structures (cast steel, cast aluminum, etc.) are also used.

3. If it is for some softer materials or small experimental force products, the surface of the fixture that contacts the sample generally uses soft rubber, etc. (for example: the clamping surface of fixtures for samples such as plastic films, fibers, etc.).

As a user, you should also understand some emergency handling methods for unexpected situations during the use of the electronic universal tensile machine, among which the more common include:

1.Electronic universal tensile testing machineWhen loading, if the pointer shakes or moves intermittently: 1) Worn clutch gear: needs repair or replacement;

2) Worn friction disc rubber washer or spring: need to replace the rubber washer or spring; 3) Displacement of the control handle: adjust the control handle to fit well with the gear slot.

2. ElectronicUniversal tensile testing machineIf the pendulum returns too quickly or too slowly: 1) Improper position of the buffer valve: adjust the buffer valve to the appropriate position;

2) Hydraulic oil viscosity is too low or too high: when the hydraulic oil viscosity is too low, the pendulum falls quickly, and when the viscosity is high, it falls slowly. Replace with hydraulic oil of appropriate viscosity.

3) Dirt in the buffer valve, oil pipe, or hydraulic oil: clean the buffer valve and oil pipe. Replace hydraulic oil.

3. Electronic universalTensile testing machinePointer zero return lag or instability: 1) Rust or oil contamination on the pointer bearing or spindle bearing: clean or replace the bearing.

2) Deformation of the rack or misalignment with the gear: straighten the rack or clean and adjust the gear, pulley, and other transmission components.
