The HZ‑7001A Moving Die Rotor Rheometer (MDR) is high‑precision rotor‑less vulcanization testing instrument widely adopted in rubber industry laboratories. By oscillating sealed test cavity under precise constant temperature, it detects torque variation of rubber sample during vulcanization process. This device outputs complete vulcanization curve and key parameters including ML, MH, ts1, ts2, t10, t50, t90, Vc1, Vc2. It supports both manual panel operation and computer software control. It is essential quality‑control apparatus for rubber formula R&D, raw material incoming inspection and production quality monitoring, complying with GB/T16584, ISO 6502, ASTM D5289 standards.
HZ‑7001A moving die rotor rheometer adopts advanced alpha closed‑cavity sealing structure. Rubber specimen is placed inside nearly fully enclosed test cavity under stable preset temperature. The lower die generates small‑amplitude oscillation to apply shear force to rubber sample. The instrument captures reaction torque produced by rubber shearing, converting torque change over time into standard rubber vulcanization curve.
It can accurately obtain scorch time, optimum curing time, vulcanization rate, minimum torque ML and maximum torque MH. The high‑accuracy torque sensor reaches 0.001 N.m resolution. Built‑in high‑performance pneumatic system ensures stable sample clamping and sealing, avoiding sample overflow and improving test repeatability.
This rheometer applies to tire manufacturing, wire & cable, automotive rubber components, sealing parts, medical rubber goods, university laboratories and third‑party inspection institutions.
Compliant Standards：‑ GB/T 16584 ‑ ISO 6502:1991 ‑ ASTM D5289‑95
