The Automatic Hardness and Density Testing Machine is designed for high-throughput hardness and density measurement of rubber samples. It is mainly used in tire factories, sealing product manufacturers, rubber mixing centers, and rubber raw material laboratories. The system automates the entire testing process—combining robotic sample handling, digital Shore durometers, and high-precision balances—to ensure efficient, accurate, and low-error measurement of both hardness and density.
Application
(1) Soft rubber and natural rubber products: hardness and density testing.
(2) Tire industry: rapid inspection in rubber mixing centers, raw material quality control, batch consistency checks.
(3) Sealing products and rubber parts: performance evaluation and quality control.
(4) Rubber compounding and raw material testing: formula optimization and pre-vulcanization sample assessment.
(5) Laboratory high-throughput testing: suitable for hundreds to thousands of samples per day.
(6) R&D and QC workflow: evaluate hardness and density parameters, optimize production processes, and verify compliance with standards.
Standards
(1) GB/T 531.1-2008: Rubber hardness measurement (Shore A/D).
(2) GB/T 531.2-2008: Rubber hardness measurement (IRHD method).
(3) ISO 7619-1: Rubber and elastomer Shore hardness measurement.
(4) ISO 2758: Rubber density measurement via displacement method.
(5) DIN ISO 7619 / DIN EN ISO 868 / ASTM D 2240 (hardness).
(6) ISO 2781 / DIN EN ISO 1183-1 / ASTM D1817 (density).
