MR-50T High-Precision Laboratory Vulcanizing Press

Advanced Dual-Layer Compression Molding System for Material R&D

1. Product Overview

The MR-50T Closed Vulcanizing Press is engineered for high-precision compression molding and vulcanization of rubber, plastics, resins, and advanced composite materials. Featuring an innovative dual-layer workspace integrated with a heavy-duty four-column structure, it is the ideal asset for aerospace R&D, military/defense research, national laboratories, and elite technical universities.

2. Premium Performance Highlights

• Advanced Thermal Management (±0.5℃ Accuracy): Specially designed electro-heating tubes compensate for heat loss based on platen dimensions. The maximum temperature deviation across the platen area does not exceed ±0.5C within 60 minutes, ensuring unparalleled molding uniformity.

• Dual-Layer Integrated Work Area: An efficient layout featuring an upper electro-heating zone and a lower water-cooling zone. The lower plate integrates a serpentine water-cooling pipe system for rapid cooling and fast, precise sample de-molding.

• Heavy-Duty Frame & Premium Metallurgy: Built with high-strength precision guide pillars and heavy-duty structural steel to prevent deformation under high pressure. Platens are crafted from SKD Chromium-Molybdenum alloy, featuring a surface hardness of 60 HRC via deep nitriding, polishing, and hard chrome plating.

• Intelligent Dual-Speed Hydraulic System: Driven by a YUKEN pump and a proportional valve control system. It operates in a smart dual-speed mode—high approach speed (≥20mm/s) at low pressure and slow locking speed (≥1.5mm/s) at high pressure—to protect delicate molds and optimize energy consumption.
