Auto Tensile Tester
One machine for tensile, peel, tear, seal strength, puncture and compression tests — the general-purpose workhorse for mechanical properties of packaging materials.
Purpose | What it does for you
Tests tensile strength, elongation at break, elastic modulus, peel strength, tear strength, seal strength, puncture force and compression of plastic films, laminates, adhesive tapes, paper, rubber and metal foils. By changing fixtures and calling the matching test method, one machine covers most mechanical items in incoming inspection and production — avoiding duplicate purchases for single tests.
Key Features
- One machine, many tests: swap fixtures for tensile, peel, tear, seal, puncture and compression
- Servo drive with stepless speed control, wide speed range and high force accuracy
- Wide choice of fixtures and accessories covering different standards and specimen forms
- Software displays live force–displacement curves and outputs multi-format reports automatically
- Limit, overload and emergency-stop protection for safe operation
- Optional GMP Computerized System module for data audit trail requirements
Operating Principle
The specimen is gripped between a moving and a fixed fixture. A servo motor driving a ball screw moves the crosshead at a set speed, applying tensile (or compressive) load; force and displacement sensors acquire load and deformation in real time, and the software plots a force–displacement (stress–strain) curve and calculates tensile strength, elongation at break, elastic modulus, peel strength and other parameters.

Frequently Asked Questions
We need both peel and seal-strength tests — do we need two machines?
No. The tensile tester handles both by changing fixtures and selecting the matching test method; the software ships with the relevant standard method templates. Just list the tests you need when requesting a quote and we will configure the fixture package accordingly.
Does LabStone support OEM/ODM and customised instruments?
Yes. Standard models ship as-is, while chamber count, specimen size, fixtures, temperature range and software modules (including the GMP Computerized System module) can be tailored to your SOP and URS. IQ/OQ/PQ validation documentation packages are available.
What is the typical lead time, and how is shipping handled?
Standard models usually ship in 4–8 weeks; customised builds depend on the agreed scope. Instruments are packed in export wooden cases and can move by sea, air or rail. We supply proforma invoice, packing list and certificate of origin (CO / Form E), and work under EXW, FOB, CIF or DAP terms.
How are installation, training and calibration handled after delivery?
We provide remote installation guidance, bilingual (Chinese/English) manuals and video training; on-site commissioning by our engineers is available. Users can self-calibrate with standard weights, reference films or calibrated leak standards, and third-party calibration certificates can be supplied.
What is the warranty, and how are spare parts supplied?
The instrument carries a 12-month warranty from acceptance plus lifetime maintenance support. Consumables (molecular sieve, desiccant, sealing grease, printer paper) are kept in long-term stock, and key components are international brands available worldwide. We respond to technical enquiries within 24 hours.
Do the instruments comply with ASTM, ISO and pharmacopoeia standards?
Yes. Every instrument lists its applicable standards on the specification page (ASTM, ISO, GB, YBB, Chinese Pharmacopoeia, USP, EP, JIS, DIN, TAPPI and more). The software outputs raw records and reports suitable for audit trails, with an optional GMP / FDA 21 CFR Part 11 compliance module.
Which languages does the software support, and can it integrate with a LIMS?
The software ships with Chinese and English interfaces; other languages can be added on request. Data export is available over RS232, USB, Ethernet or Wi-Fi, and reports can be exported to Excel, PDF or structured files for LIMS integration.
