PERCUSSION AND ROTATION

Rotary decoring systems

The turning decoring station is used when hammering alone cannot sufficiently empty a casting. F+K hammering units break the sand core and set the casting in vibration. At the same time, the fixture can rotate the casting by up to 270° so that loose core sand can escape from the cavities. This method is suitable for decoring tasks where rotation is sufficient and no additional vibration treatment is required.

Which solution fits?

How the machine works

Hammer and rotate

Hammering units break the core. At the same time, the fixture rotates the casting by up to 270° so broken sand can leave its cavities.

When to use rotation

This method is suitable when turning assists sand discharge and no additional vibration is required. Fixture and motion are tailored to the casting.

Loading

Manual, robot, rotary-table and through-feed loading are possible. The examples below show robot loading and a pallet circulation system.

SYSTEM EXAMPLE / KAMLIT

Universal rotary decoring system with pallet circulation

The system built for Kamlit in 2024 illustrates a configuration we can still offer today: truck engine blocks and cylinder heads in one system, four adaptable loading and unloading positions and pallet circulation. We tailor the design to your range of castings and production flow.

Hammer control during operation

The Scania and Kamlit systems feature a new hammer control system. Hammer frequency and clamping pressure can be adjusted during operation to match the decoring process to each casting and improve results.

SYSTEM EXAMPLE / SCANIA

Rotary decoring system with robot loading

Installed in Södertälje, Sweden, in 2021, this system decores the truck engine blocks and cylinder heads produced at the plant. Loading and model changeover are designed for fully automatic operation. The project illustrates another way to integrate rotary decoring into production.
