Efficient separation technology for foundries: RHEtrans and RHEflex optimize Cast Shakeout and Sand Shakeout

Foundries face the challenge of efficiently separating casting molds and sand cores from cast metal parts. This sand must be recycled.

What is Cast Shakeout and Sand Shakeout?

After the molten metal is poured into the molds and solidified, these molds need to be removed to obtain the finished castings. This process is called shakeout.

Cast Shakeout specifically refers to the separation of casting molds or cores from the cast metal parts. Cores made of materials such as ceramics, which have a different composition than the surrounding sand, are often used. To obtain the final shape of the casting, these cores need to be removed.

On the other hand, Sand Shakeout involves the separation of sand molds and sand cores from the cast metal parts. Sand is commonly used as a molding material in the foundry industry. Once the metal is cast and solidified, the sand molds need to be removed to expose the castings.

RHEtrans for efficient Cast Shakeout

RHEtrans by RHEWUM is an oscillating chute with an unbalanced drive, known for its economical conveying capability and robust, reliable construction. RHEtrans can be flexibly adapted to the specific requirements of the foundry industry. The drive is powered by two counter-rotating unbalanced motors, which are mounted laterally or underneath at an optimal angle to the trough, generating a linear vibration. This ensures high sand transport velocity.

RHEflex for precise Sand Shakeout

RHEflex by RHEWUM is a universal linear vibrating screening machine, ideally suited for Sand Shakeout. With its linear vibration motion, it enables precise classification and efficient recovery of sand particles from the castings. The machine is designed to be robust and durable, capable of withstanding the demanding requirements of sand processing. Easy maintenance and cleaning contribute to maximum uptime and efficiency.
