VARIANT - HESS Group

Compaction
The VARIANT by Schlosser-Pfeiffer works „below floor
level“ to keep noise emissions reduced to a minimum and
absorbs the vibrations occurring during production.
The concrete is filled evenly into the mould by a rotating feeding
belt. Concrete filling speed is individually adjustable for all production
circumstances. The vibration are generated by a central
vibrator connected to the core via a hydraulic clamping device.
This design allows rapid mould changes. The mould jacket with
base pallet is rubber-buffer isolated and mounted separately
from the other machine components to ensure proper induction
of the vibration into the product. The centrifugal force is
also individually adjustable in accordance with product type and
diameter.
The advantages of this feeding and vibration technology by
Schlosser-Pfeiffer include high-grade and uniform compacting,
consistent product wall thickness, perfect coating of the reinforcements,
smooth inside and outside surfaces, and dimensional
accuracy.
To shape the spigot ends, the spigot forming ring is first applied
with its dead weight only (free load), hence allowing even distribution
of the concrete. A hydraulic superimposed load may be
added as needed. The spigot end is smoothed by the oscillating
rotary movements of the spigot forming ring. The result: Perfectly
and precisely shaped spigot ends suitable even for gaskets
designed for narrow tolerances.
