Computerized Servo Universal Testing Machine

Short Description:

The Computer-Controlled Servo Universal Testing Machine is a high-precision mechanical testing system designed to evaluate the tensile, compression, bending, shear, tear, peel and other mechanical properties of various materials and finished products.

Equipped with a digital Load Cell, Panasonic servo motor and Taiwan TBI ball screw, the machine provides precise force and displacement control over a wide testing speed range of 0.001–500mm/min. The computer-controlled system can automatically calculate test results and generate force-displacement curves.

With suitable fixtures, the machine can also perform constant stress, constant strain, creep, stress relaxation, torsion and cup drawing tests. It is widely used for textiles, plastic films, composite films, woven bags, flexible packaging, adhesives, adhesive tapes, rubber, paper and other materials.

Product Presentation
This computerized servo universal testing machine (UTM) uses a digital load cell and closed-loop servo control to measure tensile, compression, bending, shear, tear and peel strength in both longitudinal and transverse directions. Beyond standard ramp tests, it supports constant-stress, constant-strain, creep and relaxation multi-loop test modes, and with dedicated fixtures can also perform torsion and cupping (Erichsen-type) tests.

The 0.001–500 mm/min speed range, 1/100,000 resolution and ISO 7500-1 Class 0.5 load accuracy make the machine suitable for both routine quality control and R&D material characterization. Test data — force, elongation, stress, strain, holding force and flexure — are calculated automatically by the PC software, displayed as real-time curves and exported for reporting.

Product parameters
1	Capacity options	10kg, 20kg, 50kg, 100kg, 200kg, 500kg, 1000kg, 2000kg
2	Unit Switching	All international units can be switched freely
3	Resolution	1/100,000, accuracy 0.5 grade
4	It can perform tensile force, extension, stress, strain, and display curves, holding pressure, and bending
5	Maximum stroke	1000mm(including fixtures), left and right span: 410mm(standard machine configuration)
6	Protection device	It includes upper and lower stroke control switches, program-set maximum load, maximum extension, and automatic shutdown emergency switches. The drive motor is a servo motor, which is fully controlled by a computer for speed and stroke. Different traditional AC and DC motors are controlled by voltage and need to be controlled in different sections, resulting in poorer control accuracy.
7	Test speed	0.001 to 500mm/min
8	Power Supply	1∮,AC220V,15A
9	Fixtures	One set of tensile fixtures (for tensile, tear and peel tests)
10	Function	The computer software automatically calculates the test results for tensile, tear, peel, bending, etc., and displays the curve graph
11	Force value accuracy	within ±0.3%
12	Motor	Panasonic servo motor from Japan
13	Software System	Universal high-precision and economical system, independently developed by Lituo
14	Support double columns	Made of high-grade aluminum alloy material
15	Host color	Military green
16	Screw	Taiwan TBI ball screw

Product Advantages

Servo Closed-Loop Control – Full computer control of speed and stroke across 0.001–500 mm/min delivers continuous rate accuracy that AC/DC motor drives cannot achieve in stepped segments.
Class 0.5 Load Accuracy – A digital load cell with 1/100,000 resolution reads force to ±0.5% of indicated value, satisfying ISO 7500-1 Class 0.5 verification.
Five Test Types, One Frame – Tensile, compression, bending, shear, tear and peel testing are all available through interchangeable grips, avoiding separate single-purpose machines.
Multi-Loop Advanced Modes – Constant stress, constant strain, creep and relaxation cycles extend the machine from QC checks to material research work.
PC Software with Live Curves – Force, elongation, stress and strain are computed automatically and plotted in real time, so results are ready for reporting without manual calculation.
Layered Safety Protection – Travel limit switches, programmable load and extension cut-offs, and an emergency stop protect both operator and specimen during high-force runs.
