Chongqing Wanwei Instruments launches its brand-new dual-station automatic cross-cut tester. Equipped with synchronous dual-station operation and fully automatic precision grid scribing, it resolves three major industry pain points including low efficiency, severe human errors and unstable test data, making it an essential device for production line quality inspection and laboratory sampling tests.

1. Synchronous Dual-station Testing Doubles Inspection Efficiency

The dual-station design breaks the limitation of traditional single-sample testing machines: ✅ Two workpieces can be loaded simultaneously, and one startup completes two sets of standard cross-cut tests at the same time; ✅ No batch cycle testing is required, cutting testing time for mass samples by half; ✅ Compatible with diverse inspection scenarios: assembly line testing, multi-sample comparison in R&D labs, and incoming material sampling inspection.

A single machine delivers double testing capacity, greatly cutting labor costs at inspection stations, shortening sample testing cycles and helping factories improve overall delivery efficiency.

2. Fully Automatic Closed-Loop Operation Eliminates Manual Operation Errors

The entire process from workpiece clamping to standard grid scribing runs automatically, eliminating repeated manual parameter adjustment and alignment calibration, with consistent test conditions for every group:

Automatic locking and positioning: The workbench clamps samples tightly to prevent shifting or sliding throughout testing, avoiding inspection deviations caused by specimen displacement;
Multi-dimensional adjustable workbench: Supports forward-backward translation and multi-angle rotation to firmly fix flat panels as well as special-shaped curved workpieces;
Constant-force vertical constant-speed scribing: The cutter drops vertically and moves at a steady speed with fixed cutting force and travel speed throughout the whole test.

Manual testing inevitably leads to hand shaking, uneven force and misalignment, resulting in inconsistent grid depth and distorted lines. In contrast, the automatic tester produces neat, uniform grids with fully consistent cutting depth. Its stable, repeatable test results are authoritative and compliant, fully meeting the national standard GB/T 9286 for cross-cut tests.

3. Standardized Tear Test for Intuitive Evaluation of Coating Adhesion

After automatic grid scribing, take out the test panel, firmly press special adhesion tape onto the grid area and tear it vertically upward at a constant speed. Coating quality can be clearly judged under a magnifying glass: ✔ Qualified coating: Complete, intact grids with no peeling, flaking, powder loss or edge chipping, indicating qualified adhesion performance; ✘ Unqualified coating: Paint chipping along grid edges or large-area coating peeling, with obvious adhesion defects visible at a glance.

The standardized testing process unifies evaluation criteria, reduces subjective judgment differences among inspectors and enables more precise grading of coating quality.

4. Wide Industrial Compatibility: One Machine for All Coating Inspection Tasks

It applies to most industries with surface coating processes for paint film, ink and spray coating adhesion testing:

3C plastic housings and home appliance plastic parts
Hardware sprayed components and metal baking paint plates
Printed ink and UV coating products
Architectural paint materials and decorative panels

Replacing traditional manual cross-cut knives, this machine cuts labor training and staffing costs, unifies factory-wide quality inspection standards and realizes standardized control of coating quality.
