Description
LINA LN-250T Intelligent Pressure-Regulating Vulcanizing Press
—Every rubber sheet is formed at the “golden pressure” in one shot
1. Product Positioning
The LN-250T is a four-column down-stroke vulcanizing press engineered by LINA for high-end rubber manufacturers. Integrating 2 500 kN clamping force, servo pressure regulation, PID accurate temperature control and one-click mold change, it offers stepless 0–25 MPa adjustment for flexible production of O-rings, oil seals, anti-vibration pads and thermal pads in small-batch, multi-specification scenarios.
2. Core Advantages
- 0–25 MPa Servo Pressure Regulation
Yaskawa servo pump + high-precision pressure sensor, closed-loop control, pressure fluctuation ≤ ±0.3 bar; ten-segment programmable pressure profiles for foaming, degassing, holding, secondary pressing and other complex processes. - 500 × 500 mm Large Platen Area
Mirror-chrome platens with flatness ≤ 0.02 mm/m; zone PID control, temperature uniformity ≤ ±1 °C. - One-Click Quick Mold Change
Pneumatic clamping + T-slot + locating pins; one operator can finish mold swap within 3 minutes; mold ID auto-recognition and recipe auto-loading eliminate human error. - Smart HMI
10″ color touch screen, 200 recipe memory, USB/Ethernet data export; optional MES interface for real-time cloud upload of OEE, energy and status data. - Energy & Safety
Servo pump consumes only 35 % of traditional fixed-displacement pumps, noise ≤ 68 dB(A); four-side safety light curtain + mechanical lock + hydraulic dual interlock, CE/UL compliant.
