Frequently Asked Questions (FAQ):
Q1: Does this tester only perform tests according to ISO 7438?
A1: While it is specifically designed and calibrated for full compliance with ISO 7438 (Metallic materials — Bend test), it can often be configured or used with appropriate fixtures to perform bend tests described in other related standards (like ASTM E290, JIS Z 2248, or GB/T 232) upon request. The core functionality of controlled bending angle and force measurement is versatile.
Q2: How is the specimen clamped and bent?
A2: The tester uses precision-ground mandrels (of varying diameters as per the standard) and support rollers. The specimen is placed across the supports. The automated arm then pushes the specimen down onto the central mandrel at the programmed speed, creating the controlled bend. Fixtures are designed for secure clamping without damaging the specimen prematurely.
Q3: What kind of data output does the machine provide?
A3: The tester records and displays key parameters in real-time, including applied force, bend angle, and time. It typically outputs a complete load vs. displacement/angle curve. This data can be viewed on the LCD screen and exported via USB or RS232 interface for storage, analysis, and report generation on a connected PC. Software for comprehensive data analysis is often available.
Q4: Is calibration included, and how often is it needed?
A4> The instrument is factory calibrated before shipment. We provide a calibration certificate traceable to national standards. Regular recalibration is essential to maintain accuracy. The recommended recalibration interval depends on usage intensity and your quality system requirements (commonly annually). We offer calibration services and can advise on procedures.
Q5: What are the power requirements, and is voltage stabilization needed?
A5: The standard power requirement is 220V AC (±10%), 50Hz. While the power supply tolerance is built-in (±10%), using the instrument in areas with significant voltage fluctuations or unstable power grids is highly recommended to use a voltage stabilizer to protect sensitive electronic components and ensure consistent performance.
Q6: What metallic material forms can be tested?
A6: The tester is designed for various forms, including wire, rod, bar (round, square, hexagonal), flat sheet, and strip. The specific maximum dimensions (thickness, diameter, width) depend on the force capacity of the model you select. Appropriate mandrels and supports are provided or available to handle different specimen geometries as per ISO 7438.
Q7: Does the machine require special software installation?
A7: Basic operation, test setup, and result viewing are performed directly on the machine's integrated control panel and display. For advanced data analysis, curve generation, report creation, and database management, dedicated PC software is typically provided or available as an option. This software usually runs on standard Windows operating systems.
Q8: What warranty and after-sales support do you offer?
A8: Jinan Wangtebei provides a standard warranty period (commonly 12 months) for the main unit against manufacturing defects, covering parts and labor. We offer comprehensive after-sales support, including technical assistance via email/phone, access to operation manuals and software, spare parts supply, and on-site service engineers available globally (service terms may apply). Our established presence in major markets ensures responsive support.
