Vibro-Compaction
PRINZING PFEIFFER is significantly involved in the development of the vibro-compaction and pressing method for the precast concrete
industry.
Radial-Pressing method
PRINZING PFEIFFER is mainly responsible
for the development of the
modern radial-pressing-method.
Centrifugal method
A particular advantage of the centrifugal (spinning) process is the production of longitudinally pre-stressed concrete products, such as posts, poles and pressure pipes.

Vibro-Compaction and Pressing method
PRINZING PFEIFFER was significantly involved in the development of the vibro-compaction and pressing method for the concrete precast concrete industry. PRINZING PFEIFFER has continuously developed the vibro-compaction and pressing method and adapted for an ideal production of more different concrete elements. The variety of all kind of compaction systems (e.g. central vibrator, vibration table, etc.) allow short cycle times and highest product quality.
Advantages of the Vibro-Compaction and Pressing method:
- Fast and homogenous compaction by vibration and additional hydraulic pressing force
- The highly effective central vibrator, one vibration unit for all product dimensions as a rule
- Highest product quality by the use of amplitude and frequency controlled vibrating table
- Low water-cement ratio and therefore higher strength of the concrete elements
- Short cycle times by fast compaction process and immediate demoulding
- Efficient production of all requirements up to a fully automatic production system
