Content

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).

Test Principle

(1) Hardness Testing: Samples are placed into turntable slots; the Shore durometer automatically loads and measures 3–5 points. Data is recorded in real time.

(2) Density Testing: After hardness testing, the robotic arm transfers samples to the balance, measuring density via the displacement method.

(3) Data Processing: Hardness and density results are automatically recorded, filtered, and traceable. Data can be exported to customer databases or MES systems.

Operation Instructions

(1) Load samples sequentially into sleeves and cool to 20–45 ℃.

(2) Power on the instrument and control system; check robotic arm and turntable status.

(3) Set test parameters: hardness points, holding time, cycle quantity.

(4) Start automatic testing; the system conducts hardness and density measurements.

(5) After completion, review displayed results and export data.

(6) Regularly maintain robotic arm, balance, and hardness test head to ensure long-term stable operation.
