100 Ton hydraulic press for silicone mask

By Structural Design

• Column-Type Press (e.g., Four-Column Press): Refers to the physical structure where the moving platen slides along four vertical steel pillars. This is the "H-frame" style common in Jinyu machinery.

• Platen Press: Focuses on the "platens" (the flat heating plates). In the leather and textile industries, they might call it a Flat Heat Press.

• Vertical Molding Machine: Because the pressure is applied vertically (up-and-down), as opposed to horizontal injection machines.

• By Specific Application
• • Lab Press / Laboratory Press: Used if the machine is small (like a 5-ton or 10-ton) and used for testing color pastes or material formulas before mass production.

  • Laminating Press: If the machine is being used to bond layers together (like putting a silicone label onto a fabric backing).

  

  In the world of molding machinery, 2RT refers to the Two-Roll (or Two-Plate) Turn (sometimes called "Two-Roll Transfer") mold opening mechanism. This is a specific design for the mold-out sequence used to eject finished products from a hydraulic press.

  Here is a breakdown of what the 2RT designation means for your equipment and production:

  1. The Opening Sequence

  In a standard hydraulic press without an RT system, the mold simply opens and closes. In a 2RT system, the press is equipped with a mechanical or hydraulic mechanism that performs two distinct movements during the mold-out phase:

  • Plate Lifting: The upper mold lifts away from the lower mold.

  • Mechanical Ejection/Tilting: The lower mold plate (or a specific plate layer) is tilted or slid forward, making it much easier for the operator to remove the finished silicone or PVC parts and clean the mold.

  2. Key Features of 2RT

  • Ergonomics: Instead of reaching deep into the press (which is hot and dangerous), the 2RT mechanism brings the mold toward the operator or tilts it up at an angle (usually 45° to 90°).

  • Efficiency: It significantly reduces the cycle time for "demolding." This is particularly useful for production lines making 3D labels, patches, or shoe charms where manual removal is required.

  • Safety: It minimizes the risk of operator burns because the hot mold surface is moved to a more accessible position.

  

  4. Technical Specifications

  A typical 2RT hydraulic press (like a 30-ton or 50-ton model) usually includes:

  • Pressure Stability: High-pressure cylinders to ensure the silicone or PVC material fills every detail of the 3D mold.

  • Heating Control: Independent temperature control for the top and bottom platens to ensure even curing.

  • Vacuum Function (Optional): Many 2RT presses include a vacuum hood to remove air bubbles during the pressing process, which is critical for high-quality aesthetic goods.
