Indentation offset and not in the center of view

Caused by non concentric three axes of dolphin nose indenter, spindle and worktable. Recalibrate coaxiality and adjust center positions.

Tester fails to power on with abnormal power supply

Caused by poor power cord contact, blown fuse or mismatched voltage. Check wiring, replace fuse and match rated voltage.

AI-Powered supplier vetting

SummaryEBPu Electromechanical Equipment (Zhejiang) Co., Ltd. is identified as both a trading company and manufacturer/factory based in Zhejiang, China. It offers material-testing and metallographic equipment, operates nine production lines, and reports six to ten years of R&D-engineer experience. The supplier states that it calibrates products before delivery and provides pre- and after-sales support, with customers in more than 50 countries. ISO 9001 certification is reported. Export coverage is broad, and off-peak lead time is stated as within 15 workdays. However, the evidence does not establish customization capability or provide sufficient customer-case detail. The available trade records show only limited transaction evidence and should not be treated as a comprehensive measure of commercial credibility.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory. Its legal name and registered address in Zhejiang, China are also provided, supporting identification as a China-based mixed trading and manufacturing business.

CertificationsThe supplier reports holding an ISO 9001 supplier management-system certification. This is explicit evidence of a recognized quality-management certification, although no certificate number, issuing body, or validity period is provided.

After-Sales capabilityEBP states that it provides pre-sales and after-sales support, and identifies a professional sales and after-sales team with over 10 years of exporting experience in material-testing machines. Its stated focus on long-term cooperation and service further supports service capability.

R&D capabilityThe supplier reports six to ten years of total R&D-engineer experience and lists innovation among its corporate values. These facts indicate some innovation-related resources and intent, but no specific patented technology, new product development record, or measurable innovation result is provided.

Production capacityThe supplier is identified as a manufacturer/factory, operates nine production lines, and offers a range of metallographic microscopes, testing machines, and hardness-testing equipment. It also reports six to ten years of R&D-engineer experience and an off-peak lead time within 15 workdays, supporting a stated production capability.

Product Q&A

Q:Inaccurate and deviated hardness test values

Mostly caused by worn/cracked dolphin nose indenter, unstable test force, oil impurities on workpiece surface or uncalibrated equipment. Replace indenter, clean workpiece and recalibrate the device.

Q:Unresponsive touch screen, failed buttons or garbled display

Caused by damp touch panel, loose wiring or system lag. Restart the tester, clean the screen, check wiring or restore factory settings if needed.

Q:Jittering or unstable readings during test force loading

Result from unlevel tester body, loose worktable, insufficient buffer oil or loose dolphin nose indenter. Level the device, fasten parts and refill buffer oil.

Q:Dolphin nose indenter is easy to damage with short service life

Caused by over hard/burred workpiece, fast loading speed or unstable workpiece. Polish burrs, load force evenly and place workpiece stably.

Q:Continuous fluctuation or drop of hardness value during load holding

Due to workpiece creep, loose worktable/spindle or abnormal force sensor. Adjust holding time, fasten mechanical parts and inspect sensor.
