Furnaces for hardening the graphite layer around the circumference of automotive pistons up to 250 °C

Low-temperature continuous furnaces and dryers designed for curing the graphite layer around the circumference of automotive pistons

We have designed a series of continuous kilns with a chain conveyor for this application.

One of these furnaces is the continuous drying oven SP 2800/25 with a chain conveyor and pallets for storing automobile pistons. It is an electric furnace divided into several heating zones for even temperature distribution. It also includes a cooling tunnel and a special manipulator for easy and quick transfer of pistons between the heating part of the furnace and the cooling tunnel.

The furnace is controlled by a programmable logic controller (PLC), which synchronizes the movements of the conveyor and the manipulator and communicates with the robot. The robot loads and removes the processed parts, thus replacing the furnace operator. Since the robots are responsible for handling the batch, we had to ensure that the conveyor accurately positioned the parts and did not react to temperature changes.

We routinely adapt furnaces designed for curing the graphite layer on automotive pistons to a specific operation, a specific line, to make your production as easy as possible.

What’s great about this device

• Even temperature distribution on the pistons +/- 5 °C
• Precise conveyor positioning
• Adaptation of the furnace to integrate into a specific production and line (U-shaped, continuous version, etc.)
