Tensile Tester (Servo Control) for Plastic & Polymer Testing Instruments

In plastic and polymer manufacturing, product quality depends on how a material behaves when subjected to pulling force. The Tensile Tester (Servo Control) from LabZenix Industries Pvt. Ltd. is designed to measure tensile strength, elongation, yield strength, breaking force and other essential mechanical properties with accuracy and consistency. It is suitable for plastic films, polymer sheets, flexible packaging, laminates, rubber specimens and other polymer-based products.

Developed for quality-control laboratories, production facilities and research centres, the LabZenix Tensile Strength Testing Machine/Tester combines a precision load-measurement system with servo-motor-controlled movement. Its controlled crosshead motion helps laboratories obtain repeatable results across different materials and test conditions.

What Is a Tensile Tester (Servo Control)?

A Tensile Tester (Servo Control) is an advanced material-testing instrument that applies a controlled pulling force to a prepared specimen until a specified extension or complete break occurs. During testing, the system continuously measures force and displacement.

Unlike basic motor-driven instruments, a servo-controlled tensile tester provides more precise speed regulation and smoother crosshead movement. These advantages are important when testing thin films, plastic strips, polymer sheets and flexible laminates, where even small variations in test speed can influence the final result.

The instrument can help determine:

• Maximum tensile strength

• Breaking strength

• Percentage elongation

• Yield strength

• Peak load

• Break load

• Force at a selected extension

• Extension at a selected force

• Load-versus-extension behaviour

Working Principle of Tensile Testing 🧪

Tensile Testing: A Complete Guide to Principles begins with a simple concept: a test specimen is secured between two suitable grips, and a controlled pulling force is applied in opposite directions. One grip remains fixed while the moving grip travels at a programmed speed.

The load sensor detects the applied force, while the displacement system measures the specimen’s extension. The controller processes this information and displays the results. Depending on the selected model and software configuration, test data may also be presented as a force-versus-extension or stress-versus-strain graph.

Servo-motor control enables stable movement throughout the testing cycle. This makes the Tensile Tester (Servo Control) suitable for routine quality assurance as well as detailed material evaluation.

Applicable ASTM, ISO, IS and BIS Standards

The LabZenix Tensile Strength Testing Machine/Tester can be manufactured or configured for testing in accordance with relevant national and international standards, including:

• ASTM D638 – Tensile properties of plastics

• ASTM D882 – Tensile properties of thin plastic sheeting

• ASTM D412 – Tension testing of vulcanized rubber and thermoplastic elastomers

• ASTM D5035 – Breaking force and elongation of textile fabrics

• ASTM F88/F88M – Seal strength of flexible barrier materials

• ISO 527-1 – General principles for tensile properties of plastics

• ISO 527-2 – Test conditions for moulding and extrusion plastics

• ISO 527-3 – Test conditions for films and sheets

• ISO 37 – Tensile stress-strain properties of rubber

• ISO 1924 – Tensile properties of paper and board

• IS 13360 (Part 5/Sec 1) – Determination of tensile properties of plastics

• Relevant IS/BIS specifications applicable to the material and product under evaluation

Compliance depends on selecting the correct load capacity, grips, fixtures, specimen dimensions, test speed and test procedure. LabZenix can recommend a suitable configuration based on the customer’s required ASTM, ISO, IS or BIS standard.

Why Servo-Motor Control Matters

Servo technology is one of the most valuable features of a modern Tensile Tester (Servo Control). It allows the drive system to maintain controlled movement even when the resistance of the specimen changes during testing.

This provides:

• Better speed stability

• Smooth force application

• Improved repeatability

• Accurate extension measurement

• Reduced mechanical variation

• Reliable testing of delicate plastic films

• Better control during high-extension polymer tests

For manufacturers that test several batches every day, repeatability is essential. Consistent machine performance helps laboratories compare suppliers, validate raw materials and monitor production quality.

Tensile Testing Machine Price

The Tensile Testing Machine Price depends on the required load capacity, servo-drive configuration, test-speed range, grip design, travel length, extensometer, touchscreen controller and computer software.

A low-capacity machine for thin plastic film testing will have different technical requirements from a machine intended for rigid plastic specimens or high-strength polymer products. For this reason, LabZenix provides a configuration-based quotation instead of offering one general price for every application.

Customers should share their sample type, maximum expected load, specimen dimensions, required standards and desired test parameters to receive the correct technical proposal.
