General introduction
United Test make Universal Testing Machines are known for their long lasting trouble-free performance and highest quality material used in the manufacturing process. The Hydraulic universal testing machine can perform tension, compression, flexure/bending and shearing test for kinds of specimens. Suitable for metal and nonmetal material, such as iron, steel, steel bar, rebar, cement, concrete, steel rod and so on.
Hydraulic Servo Universal Testing Machine is a high-precision mechanical
property testing device that integrates hydraulic drive technology,
servo control systems, and digital data acquisition/analysis. It is
designed to conduct static and dynamic mechanical tests on various
materials (metallic, non-metallic, composite, etc.) and structural
components, including tension, compression, bending, shear, torsion,
creep, fatigue, and impact tests.
Specially design for production, research, student training and industrial laboratory. Available in wide range of loadframe capacities (300kN to 2000kN)/(10Ton to 200Ton) and with combination of control panels (Digital, Computerised) makes United Test product range suitable for every customer requirement.
Load weighing system meets or exceeds the requirements of the following standards: ASTM E4, EN10002-2, BS 1610, DIN 51221, ISO 7500-1.
Key Features
Computer screen to display test result, computer software operate loading model, double working space, tensile test at upside of crosshead, compression and bending test between working bench and crosshead.
1 WEW series is computer screen to display test result, manual operate loading model, double working space, tensile test at upside of crosshead, compression and bending test between working bench and crosshead.
2 Total six columns structure, four column and two leading screw to make the machine more stable and long working life.
3 Add 10mm sliding plate between jaws and jaw clamping plate, to make jaw clamping plate working more long time.
4 Oil cylinder adopt clearance seal, improve accuracy and decrease friction.
5 Driver system: It adopts the hydraulic pressure to drive the cylinder, so loading on the specimen to perform the test. Hydraulic station supplies super and stable pressure to the system; the soundproof insulation can reduce the noise level of the power pack to 75 dB (A), with lower noise, tiny energy consuming and lower heat.
6 Crosshead (the middle beam) movement is by mean of motor, chain at the bottom of loadframe, driven leading screw to make crosshead up and down.
7 Security: Ram stroke position limiter; Emergency switch; the control system can protect automatically once overload.
Adopts closed-loop servo control technology, achieving precise regulation of loading rate (0.001mm/min to 500mm/min) and load holding (error ≤ ±0.5%);
Supports multi-mode control (load control, displacement control, strain control) and seamless switching between modes to meet diverse test requirements (e.g., creep test requires stable strain control, while tensile test needs load/displacement control).
Hydraulic drive provides ultra-high load capacity (up to 2,000kN or more), suitable for testing large-scale components (e.g., steel structures, concrete beams) and high-strength materials (e.g., aerospace alloys, industrial-grade steel);
Hydraulic system operates with low noise and minimal vibration, ensuring stable loading without impact, avoiding damage to samples and equipment.
Real-time display of test curves (force-displacement, force-strain, stress-strain) and automatic calculation of key mechanical parameters (yield strength, tensile strength, elongation, elastic modulus, etc.);
Data is stored in an unalterable format, supporting backup, export (Excel/PDF/Word), and traceability; some models integrate with Laboratory Information Management System for centralized data management.
Interchangeable fixtures (tensile, compression, bending, shear) enable multi-type tests on a single machine;
Adjustable test space (vertical/horizontal) adapts to samples of different sizes (from small metal sheets to large concrete blocks).
Host frame is made of high-strength alloy steel with anti-corrosion treatment, resistant to fatigue and deformation;
Hydraulic components adopt international brand parts (e.g., Moog servo valves) with low failure rate and long service life.
