Pressure Controlled Laboratory 30T Double Plate Rubber Vulcanizing Press Machine With Automatic Exhaust Function
Introduction
This series of pressure-controlled plate vulcanizing machines is designed as a primary equipment for molding both shaped and non-shaped rubber products. It is also suitable for pressing various thermosetting plastics and foam rubber/plastic products. Featuring an independent power mechanism and electrical system, the machine employs centralized button control. Both working pressure and heating temperature can be adjusted within specified ranges. This model is available in manual and semi-automatic versions.
Application Industries
The laboratory-scale plate vulcanizing machine, also known as a hot press molding machine, is mainly used for sample preparation in rubber and plastic product testing, such as: tensile tests, impact tests, compression tests, and other specimen preparations.
Features
Equipment Main Body: The main body of the equipment adopts seamless welding technology.
Exterior Finish: The exterior is treated with high-temperature baking paint for rust prevention.
Heating Platens: The upper and lower heating platens are made of quenched tool steel, offering rust resistance, wear resistance, and high hardness.
Platen Parallelism: Parallelism of the upper and lower heating plates is within 0.1 mm.
Temperature Uniformity: Temperature uniformity is maintained within ±1°C.
Adjustable Pressure: The pressure is adjustable.
Programmable Controller: Features a factory-developed programmable logic controller.
Delta PLC Touchscreen: Utilizes a Delta PLC touchscreen (Taiwan) for more convenient, faster, and more visually appealing operation.
Program-Controlled Testing: Enables programmable control of tests, yielding more specific and realistic experimental data.
Precautions
Ensure the power supply for the machine’s display and motor is connected according to the indicated specifications.
Operators must be thoroughly familiar with the operation and maintenance methods of this machine and use it with care.
Keep the operating environment clean and avoid damp conditions.
When relocating the machine, handle it with care to avoid damaging any components.
Exercise caution when replacing jigs to prevent them from falling and causing damage to machine parts.
Regularly inspect the drive belt for looseness and adjust it as necessary.
Schedule periodic inspection and calibration to ensure accuracy.
