Jinan Chenji WAW 1000 kN / 2000 kN Computer Controlled Hydraulic Universal Testing Machine
Hydraulic Universal Testing Machines
Overview
The Jinan Chenji WAW computer controlled hydraulic universal testing machine is supplied in 1000 kN and 2000 kN capacities for high-capacity tensile, compression and bending testing of steel bars, sections, plates and heavy fabricated components. As part of the WAW-D series, it uses the same electro-hydraulic servo control and software platform as the 300 kN and 600 kN models, so a laboratory can standardise on one control system across a range of frame sizes.
The machine is equipped with a computer, a printer and general test software to give an accurate determination of the tensile strength, yield strength, proof strength at non-proportional extension, elongation and elastic modulus of metallic materials, and it prints six kinds of curve together with the related test data. The software self-test function self-diagnoses problems, and the machine suits industrial and mining enterprises, scientific research units, universities and engineering quality supervision stations.

High-capacity testing and frame design
The 1000 kN and 2000 kN frames are built for the heavy end of metals testing: reinforcing bar and prestressing steel, structural sections, plate, and fabricated components. The main body measures 860 x 640 x 2300 mm for the 1000 kN model with an oil control cabinet of 1200 x 600 x 750 mm and a total weight around 3500 kg, so the machine needs a solid floor and a generous laboratory footprint. Hydraulic automatic clamps grip round specimens from Phi 20-60 mm and flat specimens up to 40 mm, and the compression plate is Phi 200 mm.
The 700 mm tension space, 650 mm compression space and 525 mm effective width allow full-size rebar samples and large coupons to be tested without the grips running out of travel, and the 30-450 mm bending roller span covers the bend tests required of reinforcing steel.
Control, software and measurement
The electro-hydraulic servo system maintains constant-load, deformation and displacement control, with stress control from 1 to 45 MPa/s and displacement control from 0.02 to 3 mm/s. Load resolution is 1/500000 of full scale, deformation and displacement accuracy are within +/-1% with +/-0.5% optional, and the load range starts at 1% of full scale, or 0.4% FS in the optional low-range configuration, so the frame can carry out a low-load test as well as a full-capacity break. The software prints force-displacement, force-deformation, stress-displacement, stress-deformation, force-time and distortion-time curves together with the related data, and its self-test function diagnoses problems.
Because the WAW-D series shares one control system from 300 kN to 2000 kN, an operator trained on a smaller frame can run the 1000 kN or 2000 kN machine with the same interface and report format.
Standards and verification
The machine is designed to ASTM E8, ASTM E4-16, ISO 6892-1:2016 and ISO 7500-1. Load accuracy is Class 1 as standard with Class 0.5 available, and the force measuring system can be verified per ASTM E4 or ISO 7500-1 so that results are traceable and comparable between laboratories. Jinan Chenji supplies the machine with a calibration certificate and full documentation, and the 1000 kN and 2000 kN models are used for acceptance testing of steel products, for structural research and for the quality control of heavy fabricated parts.

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. 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.
Request a Quotation
Tell CHENJI the largest specimen and the standard you test to, and we will confirm the WAW 1000 kN or 2000 kN frame, the grips and the software package for a quotation.
