# Press Platen Applications - Sigma Thermal

## Overview
Sigma Thermal provides heating solutions for press platen applications across various industries. Press platens are designed with channels and pathways that allow a heat medium to pass through, deposit, and transfer energy through the platen to the product within.

## Applications
- **Wood Products Industry**: OSB, MDF, and melamine line presses
- **Electronics Manufacturing**: Printed circuit boards
- **Rubber Industry**: Pre-heating rubber for injection molding under high pressure
- **Composite Materials**: Heated platen compression molding equipment
- **Graphics/Printing**: Imprinting designs or graphics onto substrates using controlled heat and pressure

## Heating Technologies

### Thermal Fluid (Hot Oil) Systems
- Fossil fuel-fired and biomass-fired hot oil systems are commonly used
- Used in combination with high flow secondary circulation loops to minimize platen thermal gradients
- Permits high operating temperatures at relatively low design pressures
- Can meet high heat requirements of composite molding

### Electric Heaters
- Provide uniform heat distribution and temperature control
- Well-suited for molding, bonding, and lamination applications

## Benefits
- High level of thermal stability for press and press platen applications
- Consistent thermal patterns that promote operational efficiency
- High product integrity
