1. XLW-H Universal Tensile Testing Machine
This equipment is suitable for testing scenarios that require extended test strokes, increased test frequencies, and pneumatic specimen clamping, meeting higher standard testing demands. It is extensively utilized in production environments and advanced quality control laboratories.
Key Specifications
- Force Range: 500 N (standard), up to 1500 N optional
- Accuracy: 0.5
- Test Speed: 1–800 mm/min, stepless control
- Stroke: 1000 mm
- Gripping Method: Pneumatic
2. XLW-L Universal Tensile Testing Machine
Compared to the XLW-H model, this equipment features a slightly smaller footprint and utilizes a manual clamping system, making it ideal for both production workshops and laboratory settings.
Key Specifications
- Force Range: 500 N (standard), up to 1500 N
- Accuracy: 0.5
- Test Speed: 0–500 mm/min, stepless control
- Stroke: 600 mm
- Gripping Method: Manual (pneumatic grips optional)
Both universal tensile testing machines, XLW-H and XLW-L from Saicheng, are suitable for testing plastic films, composite materials, flexible packaging materials, plastic tubing, adhesives, adhesive tapes, pressure-sensitive labels, medical patches, release paper, protective films, composite caps, metal foils, membranes, backing materials, nonwoven fabrics, rubber, paper fibers, and other products.
3. Test Materials and Mechanical Properties
Test Materials
Saicheng’s tensile testing machine can measure the following materials:
- Plastics and Films: Plastic films, flexible packaging materials, plastic tubing, protective films, and release paper.
- Composites: Composite materials, composite caps, membranes.
- Adhesives & Labels: Adhesives, adhesive tapes, pressure-sensitive labels, medical patches.
- Rubber & Elastomers: Rubber products.
- Metals: Metal foils.
Mechanical Properties
The primary mechanical properties that universal tensile testing machines can measure are as follows:
- Tensile Strength: The maximum force a material can withstand before breaking during tensile loading.
- Peel / Adhesion Strength: Bond performance of adhesive tapes, labels, and laminated structures.
- Tear Strength: The maximum stress a material can endure during the tearing process.
- Heat Seal Strength: The maximum tensile force a seal formed by heat sealing can withstand before failure.
- Puncture Resistance: The maximum force a material can withstand before being pierced by a sharp object or puncture tool.
- Opening Force: Maximum force required to open sealed packaging.
- Low-speed Unwinding Force: A common performance metric in the film, composite, and roll material industries, primarily used to evaluate the resistance to unrolling or pulling at low speeds.
- Peel Force: The force required to manually or mechanically separate a material.
- Compressive Strength: The maximum load a material can bear under compression.
4. XLW-H UTM vs XLW-L UTM
By comparing these two devices, you can select the one that best suits your testing needs.
| Difference | XLW-H | XLW-L |
| Stroke Length | Longer (1000 mm) | Standard (600 mm) |
| Gripping Method | Pneumatic (standard) | Manual (pneumatic optional) |
| Test Speed | 1–800 mm/min, stepless control | 0–500 mm/min, stepless control |
