Laboratory Press

1. Material Molding & Sample Preparation
   It is designed to shape rubber, plastics, elastomers, and composite materials into standardized test specimens (such as sheets, discs, or custom shapes) under controlled temperature, pressure, and time. These specimens are essential for subsequent performance evaluations, including tensile strength, hardness, elongation, tear resistance, and aging tests.
2. Vulcanization & Curing Processes
   For rubber materials, the machine simulates industrial vulcanization—applying heat and pressure to crosslink polymer chains, transforming raw rubber into a durable, elastic state. It enables precise control over vulcanization parameters (temperature, pressure, duration) to study and optimize curing conditions for new rubber compounds.
3. Research & Development
   In material R&D, it supports experiments on new formulations, additives, or processing techniques. Scientists use it to test how different materials respond to varying molding conditions, helping develop high-performance products with improved mechanical or chemical properties.
4. Quality Control & Small-Batch Production
   It ensures consistency in material quality by replicating production-line conditions on a lab scale. Manufacturers rely on it to validate batch uniformity, troubleshoot production issues, or produce small quantities of specialized components for prototyping.
5. Composite Material Fabrication
   It facilitates the bonding and shaping of multi-layer composites, ensuring proper adhesion between layers through controlled heat and pressure—critical for developing advanced materials used in aerospace, automotive, and construction sectors.

Technical Parameters

1. Temperature: Ambient temperature ~ 300℃, controlled by Delta temperature module with a temperature resolution of 0.1℃.
2. Pressure: 30 tons. Equipped with a joint-venture brand pressure sensor, featuring digital setting of pressure within the range of 0~50 tons and PID-controlled pressure value.
3. Hot plate size: 40x40cm, with surrounding heat insulation layers wrapped in steel plates.
4. Distance between hot plates: 200mm.
5. Temperature accuracy: ±1%.
6. Temperature uniformity of heating plates: ±1%.
7. Hydraulic system: Adopts a hidden oil pressure system design for a neat and tidy appearance, with a two-speed design. It uses a fast lifting mode before the pressing plates make contact, and switches to a slow lifting mode after the plates come into contact with pressure, ensuring minimal pressure overshoot.
8. Control method: HMI color LCD touch screen + PLC programmable controller.
9. Ventilation process: This function can be optionally enabled or disabled. Many rubber compounds need to release air bubbles before formal pressure vulcanization. The general process involves closing and opening the mold several times with very low pressure.
10. Test process:

1. Set temperature, pressure, and time. After reaching the set temperature:
2. The user places the mold and clicks the “lift” or “test” button.
3. The mold closes and pressurizes. Once the set pressure is reached, the pressure is automatically maintained at a constant value, and timing starts.
4. When the set time is reached, the mold opens automatically, the test ends, and a buzzer alarm is triggered for notification.
   11. Safety protection:
5. Protective door limit switch: The software can set whether to stop lifting or lowering when the door is opened.
6. Emergency stop switch.
7. After the test, the software can set whether to stop heating. If “not stop” is selected, heating will continue indefinitely once temperature control is activated.
   12. Cooling method: Natural cooling.
