WEW-300BD / 600BD / 1000BD Microcomputer Screen Display Universal Testing Machine
Hydraulic Universal Testing Machines
Overview
The WEW-300BD / 600BD / 1000BD is a microcomputer screen display universal testing machine used mainly for the mechanical performance tests of metal and non-metal materials – tension, compression, bending and shearing. It is supplied with a computer, printer, electronic extensometer, photoelectric encoder and general test software, so it can accurately measure tensile strength, yield strength, specified non-proportional elongation strength, elongation and elastic modulus.
Because the machine is a hydraulic universal testing machine, the test force is applied by a hydraulic power unit rather than a screw drive, which suits the high-capacity testing of bar, rebar, plate and structural specimens where a 300 kN to 1000 kN frame is needed. Test results can be queried and printed, giving six curves – force-displacement, force-deformation, stress-displacement, stress-deformation, force-time and deformation-time – together with the related test data.

Hydraulic loading and automatic clamping
In a hydraulic universal testing machine the force comes from a hydraulic power unit, and this frame is offered in 300 kN, 600 kN and 1000 kN capacities so that rebar, plate and structural specimens can be tested close to their full strength. The clamping method is automatic, which speeds up specimen changes on a busy machine and gives a repeatable grip each time. The test force is indicated with a relative error of ± 1% and a resolution of 0.01 kN, and the deformation channels are accurate to ± 0.5% FS.
Screen display, software and six curves
The microcomputer screen display system, together with the electronic extensometer and photoelectric encoder, measures tensile strength, yield strength, specified non-proportional elongation strength, elongation and elastic modulus. Results can be queried and printed, and the software plots six curve types – force-displacement, force-deformation, stress-displacement, stress-deformation, force-time and deformation-time – with the associated data. The software includes a self-test function and can self-diagnose faults.
Applications and frame sizes
The machine is an ideal testing equipment for industrial and mining enterprises, scientific research units, colleges and universities, and engineering quality supervision stations. The three capacities differ mainly in the specimen space and platen: stretching space is 550 / 650 / 750 mm and compressed space 380 / 380 / 460 mm, with flat-specimen clamping width of 70 / 75 / 75 mm and net weights of about 1900 / 2100 / 2700 kg. The oil pump motor is 1.1 kW and the crossbeam motor 0.75 kW.
Frequently Asked Questions
What capacities are available in this series?

About CHENJI & Support
CHENJI is the brand of Jinan Chenji International Trade Co., Ltd. (Shandong, China), a manufacturer and exporter of material testing machines since 2014, with in-house quality control plus third-party inspection by SGS or Bureau Veritas. The company holds ISO 9001 certification (626024QH073R1) and is a Bureau Veritas audited supplier (MIC-ASR2451820). Testing machines are normally supplied with a calibration certificate valid for 12 months and traceable to national force standards, and our engineers help you select the machine, fixtures and accessories for your specimen and method.
Every quotation is prepared against the standard you test to, so the delivered machine matches the test method rather than only the headline capacity. Spare parts, consumables and calibration support are available after delivery, and machines can be produced to OEM or ODM requirements when a customer drawing or specification is provided.
Selecting and Verifying a Testing Machine
Choosing a machine is a matter of matching capacity to the specimen and the method, not of buying the largest frame. A 1000 kN machine is not suitable for a sample that needs 1 N of force; capacity selection follows the specimen and the standard, and the force measuring system should be verified per ISO 7500-1 or ASTM E4 on a regular schedule. Load cells are commonly supplied as class 0.5 or class 1, which means the indicated force stays within ±0.5% or ±1% of the true force.
Test results are only comparable when they are quoted together with the standard, the specimen geometry, the test speed and the force measurement class. We are glad to review your test method and specimen so that the machine, fixtures and accessories are correctly specified before you order.
