In the context of silicone and rubber hydraulic presses, 2RT refers to a specific type of automatic mold-opening mechanism. Jinyu Machinery provide Silicone Machines with different configrations.
The "RT" stands for "Release" or "Return," and the number refers to the number of stages or plate movements in the ejection sequence. A 2RT machine typically utilizes a two-plate mold and a single-stage ejection system, where the mold opens and the product is either manually or automatically pushed out in one primary motion.
A 100-ton hydraulic press for silicone products is typically a compression molding machine or vulcanizing press. These machines use high-pressure hydraulic cylinders to compress high-consistency rubber (HCR) into heated molds, ensuring even material distribution and precise curing. Dongguan Jinyu Machinery provides 30-100Ton hydrualic machine.
Industrial Vulcanizing & Compression Presses
For consistent silicone production, look for machines specifically labeled as "vulcanizing presses" or "plate presses." These include integrated heating elements and cooling systems essential for silicone's chemical cross-linking.
Full Automatic 100 Ton Rubber Hydraulic Vulcanizing Press: This vertical structure machine is designed for high-volume production. It features a PLC touch-screen system to automate parameters like curing time and temperature, and its vertical design allows for better pressure distribution.
100-Ton 2RT Hydraulic Press Features
A 100-ton press with 2RT functionality is a standard workhorse for high-precision silicone parts like O-rings, gaskets, and 3D labels.
Mold-Opening Style: The 2RT system is designed for Top-Opening or Sliding molds. It automatically separates the upper and lower plates, often including an "in-out" sliding table that brings the lower mold to the operator for easier part removal.
Precision Control: Advanced models use a PLC + HMI (Touch Screen) to manage the 100 tons of force, ensuring the pressure is applied consistently to prevent "flash" (excess material) on the edges of the silicone.
Dual-Stage Speed: These machines typically feature a fast approach (to save time) and a slow locking speed (to protect the mold and ensure accurate material flow).

Key Technical Specifications (100-Ton Class)
When sourcing a 100-ton 2RT press, these are the standard parameters to verify:
Clamping Force: 1000 kN (100 Tons).
Platen Size: Commonly 400 × 400 mm or 500 × 500 mm.
Temperature Range: Adjustable up to 300°C - 400°C with a variance of only ±2°C.
Safety Features: Infrared safety curtains and emergency reverse braking are standard for modern industrial exports.
Vacuum Option: Many 100-ton 2RT presses can be equipped with a vacuum hood to remove air bubbles, which is critical for high-quality silicone medical or electronic parts. More hydrualic machines, you can check on Jinyu Machinery of Silicone hydraulic machine with vacuum.
