The 1000×1000mm Worktable Frame Structure Flat Vulcanizing Press Machine Is Equipped With A 400-ton Hydraulic System

It is described a very capable and heavy-duty piece of equipment. Let's break down what this specification means and its typical applications.

1. Worktable/Platen Size: 1000mm x 1000mm (1m x 1m)

   • This is a large work area, allowing you to process sizable sheets, multiple smaller parts in a single cycle, or large molds. The square shape is versatile for various applications.

2. Frame Structure:

   • This indicates a robust, C-frame or H-frame (four-column) construction made of heavy steel plates. A four-column (H-frame) structure is most common for this size and tonnage, offering exceptional stability, minimal deflection under full load, and excellent parallelism between platens. This is crucial for producing consistent, high-quality parts.

3. "Flat" Vulcanizing Press:

   • This is a hot press. The platens are heated (usually by electric cartridge heaters, steam, or thermal oil) to cure, bond, or form thermoset materials.

   • "Vulcanizing" specifically refers to the process of curing rubber—cross-linking polymer chains using heat and pressure to transform soft, tacky rubber into a durable, elastic material.

   • "Flat" emphasizes its primary use for sheet materials, molded sheets, or laminates, as opposed to a press for tires or other contoured shapes.

4. 400-ton Hydraulic System:

   • This is the heart of the machine. "400-ton" (≈ 3,500 kN) refers to the maximum force the press can exert.

   • At 1000x1000mm, this provides a theoretical platen pressure of 40 kg/cm² (or ~560 PSI). (Calculation: 400,000 kg / (100 cm * 100 cm) = 40 kg/cm²).

   • This high pressure is necessary to:

     • Force material into intricate mold details.

     • Expel air and volatiles during curing.

     • Achieve proper density and bonding in laminates.

     • Compress materials to a specific thickness.

This machine is a workhorse in industries that process elastomers and composites:

• Rubber Manufacturing: Producing rubber sheets, gaskets, seals, mats, conveyor belt splices, and rubber-lined parts.

• Composite & Laminate Production: Bonding layers of materials like fiberglass, carbon fiber, plastics, and wood (e.g., plywood, door skins).

• Plastic & PCB Lamination: Used for laminating printed circuit boards (PCBs) and decorative laminates.

• Silicone Product Curing: Making silicone sheets, keypads, and industrial components.

• Technical Textiles: Bonding non-wovens or foam fabrics.

• Research & Development: For material testing and prototyping under high heat and pressure.

• Heated Platens: Often made of high-grade, drilled tool steel for even heat distribution. Temperature range typically up to 300°C or higher.

• Hydraulic Power Unit (HPU): Includes a high-flow pump, electric motor, oil reservoir, coolers, and valves to generate the 400-ton force.

• Precision Control System: A PLC (Programmable Logic Controller) and touchscreen HMI to set and control:

  • Process Parameters: Temperature, pressure, and cure time.

  • Press Cycle: Close, press, hold, decompress, open.

  • Often includes multi-stage programming for complex recipes.

• Safety Features:

  • Light Curtains or Safety Gates: To prevent access while the press is closing.

  • Pressure Relief Valves: To prevent over-pressurization.

  • Mechanical Locks/Safety Props: For maintenance (LOCKOUT/TAGOUT).

• Hydraulic Ejection System (Optional): To help remove molded parts from deep molds.

• Water Cooling Channels (Optional): For rapid cooling after cure (improves cycle time).

• Tooling/Molds: You will need custom-designed molds or caul plates sized for the 1m x 1m platen.

• Power Requirements: Significant electrical power is needed for the heaters (can be 30-60 kW or more) and the large hydraulic motor.

• Floor Space & Foundation: This is a heavy machine (weighing many tons). A solid, level concrete foundation is mandatory.

• Cycle Time: Heating and cooling a platen this size takes time. Cycle efficiency depends on your material's required cure temperature and time.

• Parallelism Control: For such a large area, ensuring the platens remain perfectly parallel under full load is critical. Look for features like precision guide rods/bushes or even proportional hydraulic valves for auto-leveling.

You are looking at a large-format, high-tonnage, industrial hot press designed for high-volume or large-part production of vulcanized rubber, composites, and laminated materials. Its 1m² work area and 400-ton force make it suitable for demanding industrial applications where consistent high pressure and temperature over a large surface are required.
