FAQ's of DH-BR Automatic Foam Sponge Rebound Testing Machine:
Q: How is the DH-BR Foam Sponge Rebound Testing Machine operated?
A: Operation is fully automatic, controlled by a microcontroller. Users simply place the specimen, select settings via the digital LCD interface, and initiate testing. The 2 kg chrome steel ball is automatically lifted and dropped to measure rebound.
Q: What types of materials can be tested with this machine?
A: The DH-BR machine is suitable for testing the elasticity and rebound properties of foam, sponge, polyurethane (PU), latex, and other similar soft to medium materials (10~50 Shore A hardness).
Q: When should I calibrate the DH-BR machine?
A: Regular calibration is advisable, especially after relocating the machine or after extensive use. Calibration can be performed manually or automatically using the supplied reference block to ensure ongoing accuracy.
Q: Where is the data stored and how can I access it?
A: Test results are stored internally-up to 100 records. Data can be retrieved or exported through either RS232 or USB interface for further analysis or record keeping.
Q: What is the process for running a standard test with this machine?
A: To conduct a test, insert a properly sized specimen (100 x 100 x 50 mm), configure your parameters, and begin the cycle. The machine will raise and drop the impact ball, then automatically measure, display, and store the rebound value within two seconds.
Q: How does using the DH-BR Testing Machine benefit foam manufacturers and suppliers?
A: This machine provides fast, accurate, and repeatable measurement of material resilience, supporting quality control and product development. Automated features streamline workflows, enable easy compliance with industry standards, and bolster confidence in your foam products' performance.
