Multi-Layer Heat Press Machine

Multi-Layer Heat Press Machine for Transformer Insulation Processing

The TRANFOVIA Multi-Layer Heat Press Machine is a multi-opening pressing system designed to apply controlled heat and pressure to several transformer insulation workpieces within one production cycle. The term “multi-layer” refers to the machine’s multiple working openings, allowing several parts or material stacks to be loaded between separate heated platens before the press closes.

Equipment Application

This machine is used in transformer insulation processing when multiple pressboard parts or laminated insulation components need to be heated and pressed under the same process conditions. By processing several working layers in one cycle, it supports batch production while reducing the need to repeat the complete heating and pressing sequence for each individual workpiece. The required platen size, number of openings, opening height, press force and heating method should be selected according to the customer’s component drawings and production process.

Main Features

• Temperature uniformity within 2°C. The heating system is designed to maintain a consistent temperature across the working layers, helping the approved hot-pressing process remain stable from one platen to another.
• Reliable sealing design. The system is designed for good sealing and leakage prevention. The specified sealing-ring service life is more than three years under the agreed operating, maintenance and working conditions.
• Stable pressure build-up. The press rises smoothly and includes safety protection, helping operators control the closing and pressing sequence during production.
• Mitsubishi PLC and HMI. The control system provides a straightforward interface for operating the machine and managing the approved pressure and temperature settings.
• Steam or electric heating. The machine can be configured around the factory’s available heat source and installation conditions.
• Multiple working openings. Several workpieces can be processed in the same press cycle, making the machine suitable for batch hot-pressing operations.

Technical Specifications

FAQ

1. What does “multi-layer” mean on this heat press machine?

It refers to multiple working openings between heated platens. Several workpieces can therefore be loaded and processed within the same press cycle.

2. What press capacities are available?

Standard capacity options include 300 T, 600 T, 1500 T, 2000 T, 2500 T and 3000 T. Final selection depends on the required pressing area and unit pressure.

3. Can the machine use steam heating?

Yes. The machine can be configured for steam heating or electric heating. The choice depends on the factory’s utilities and process requirements.

4. What is the stated temperature uniformity?

The temperature uniformity is specified as no more than 2°C across the working system under the agreed operating conditions.

5. Are platen size and number of openings fixed?

No fixed values are provided. The platen size, opening quantity and opening height should be configured according to the workpiece and target batch output.

6. How is this machine different from a cylinder cohesion machine?

The multi-layer heat press processes several flat or stacked insulation workpieces in multiple openings. A cylinder cohesion machine is dedicated to heating and pressing the glued lap joint of a formed pressboard cylinder.
