Quadra vibrating press at the Wittenheim site

Collaboration between Heinrich & Bock and Quadra began as part of the modernization project for the Wittenheim and Steinbourg facilities. Looking for a reliable and technologically advanced partner, Heinrich & Bock’s management was quickly attracted by the innovative dimension and versatility of the equipment offered by Quadra.

New concept of vibrating press with immediate demoulding characterized by the fact that this equipment can produce according to two different modes
of operation:
• A demoulding mode by turning the mould over
• A demoulding mode by raising the mould

This special vibrating press has thus the ability to manufacture a wide range of products. The production is fully automatic with particularly optimised industrial
production rates.

Midwest plant
Midwest Dry Cast

Midwest Dry Cast, based in Luverne, Minnesota, is specialized in the manufacture of concrete products suitable for pig farms, like slats and beams. This young US company wanted to evolve into an industry of the future and decided to industrialize its productionAs a partner for this project, they chose Quadra, a French manufacturer of special machines. Quadra delivered a precast production line to meet Midwest’s high expectations in terms of productivity and product quality.

A new collaboration

To industrialize production, the choice of a partner was essential and risky for the company. For Midwest Dry Cast, this production unit project was born out of a desire to evolve into an industry of the future. In addition to productivity criteria and product quality, this plant was part of a global process of improvement and progress. This is how operators’ health and safety and environmental criteria were taken into account in the development of the project.

An innovative concept

The kinematics of the plant allows to use two molds at the same time. An automatic mold handling and movement system positions one mold at the manufacturing workstation while the other is installed at the finishing workstation. The following operations are carried out at the manufacturing workstation – placement of reinforcements, concrete filling and vibro compaction. While the following actions are happening at the finishing workstation – trowelling, demolding, and quality control. The production cycle is split into two phases of similar duration.
