SMC Insulation Panel Forming Press

SMC insulation panel is also known as SMC molded board, DMC high-pressure resistant board, and unsaturated polyester fiberglass board. It is a plate-shaped product of various colors, made by compression molding an unsaturated polyester fiberglass-reinforced sheet molding compound. The SMC insulation panel molding hydraulic press is specialized hydraulic equipment used to press SMC sheet molding compound into electrical insulation boards in a single process, using high temperature and high pressure.

It provides stable, controllable high-tonnage pressure via a hydraulic system, combined with upper and lower heating molds (hot plates). Within the set temperature, pressure, and holding time, it compresses the SMC material into:

• High-strength
• High insulation performance
• High dimensional accuracy
• Stable surface quality

electrical insulation boards or insulation structural components.

SMC insulation boards possess excellent insulation properties and mechanical strength, and are widely used in substations, power plants, distribution rooms, laboratories, and outdoor live-line work. They are generally available in different specifications, such as 1.25 meters x 2.5 meters with thicknesses ranging from 2mm to 80mm, and 1 meter x 2 meters with thicknesses ranging from 0.5mm to 100mm. Different tonnage hydraulic presses can be selected according to specific needs.

The SMC insulation board forming press is easy to operate and has adjustable working parameters. The system can be equipped with an optional in-mold core pulling control system and a preset in-mold ejection control system. It can perform a series of actions, including rapid descent, segmented pressing, segmented degassing, working, pressure holding, slow mold opening, rapid return, slow demolding, rapid ejection, ejection dwell, and rapid retraction, with multi-point temperature control.

Key Features of the SMC Insulation Panel Forming Hydraulic Press:

✅ 1. Molding pressure specifically designed for insulation boards

• Tonnage range: 500 tons – 3000 tons (larger sizes customizable)
• Uniform pressure distribution ensures consistent board thickness and prevents air bubbles.

✅ 2. Equipped with heating plates for precise temperature control

• Independent temperature control for upper and lower hot plates
• High temperature control accuracy ensures complete resin curing and improves insulation performance.

✅ 3. Stable machine structure

• Common structures: Four-column type / Frame type
• High rigidity and minimal deformation, suitable for continuous production of large-sized insulation boards.

✅ 4. PLC intelligent control

• Pressure, stroke, temperature, and holding time are programmable.
• Molding parameters can be stored, facilitating switching between different insulation board specifications.
