Can a Fully Automatic Cupping Tester Deliver Consistent ASTM E 643-78 Standard Erichsen Test Results for Sheet Metal?

JINAN, China –  HST GROUP , a professional manufacturer of metal mechanical Testing equipment, rolls out its

HST-BPT-60 Computerized Erichsen Cupping Testing Machine, a high-precision Cupping Tester fully compliant with ASTM E 643-78 and GB 4156-84 standards, bringing standardized ball punch deformation Testing solutions for sheet metal, strip steel and thin metal raw material labs worldwide.

Industry Demand for ASTM E 643-78 Compliant Cupping Test Equipment

ASTM E 643-78 is the longstanding North American standard governing ball punch deformation (Olsen cupping) tests to evaluate the ductility and stretch-forming performance of metallic sheet materials, covering standard specimen thickness from 0.1 mm to 2 mm. For automotive stamping, home appliance manufacturing, steel rolling and metal processing enterprises exporting to the U.S. market, lab test data must strictly follow ASTM E 643-78 procedures to pass third-party material certification.

Traditional manual cupping testers face obvious drawbacks: unstable clamping force, manual reading errors, slow data recording and inconsistent test endpoints when cracks form, which easily invalidate ASTM E 643-78 test repeatability requirements. To resolve this industry pain point, HST GROUP developed the HST-BPT-60 automatic Cupping Tester with full computerized control, fully matching all technical specifications of ASTM E 643-78 cupping test.
