New concept of vibrating press with semi-dry demoulding by turning over: manufacturing of manholes & a large diversity of products – equipment commissioned in Reunion Island

Created in 1988 by Mr Pascal Leandri, the company Prefabeton, based on the island of Reunion in France, is specialised in precast concrete products designed for road works, building, construction and public works. Prefabeton has successfully ensured its leading position by investing in effective production equipment. The leading manufacturer within its area, Prefabeton has enlarged its products range over the years: slabs, pavers and kerbstones with high added value, blocks, vegetative retaining walls, manholes, gutters, rainwater scuppers and other concrete products designed for companies, craftsmen, municipalities and private individuals. In 1997, Prefabeton became the first company on the island of Reunion to obtain the standard called “NF” for its manhole range. This quality process is now applied to all its products, along with CE branding in order to provide its customers with certified products. The first collaboration between Prefabeton and Quadra was in 1999 when Prefabeton bought their first production unit with block machine. This long-standing client has recently commissioned the equipment manufacturer Quadra with a large-scale project: the manufacturing of solid products with semi-dry demoulding by turning over, through a fully-automated process. This production was originally ensured by its operators working on machine type vibrating tables or small rollover machines. The main production for which this new equipment was intended was the manufacturing of manholes and seating rings and extended to other products such as low walls, retaining building blocks, drainage channels and other products with suitable dimensions for the curing chambers.

Fully Automated mould change in a block machine: new patented system

To meet the requirements of the market, a key concern for the concrete manufacturer is to succeed in reconciling flexibility, productivity and safety, while offering an ever-larger range of high-quality products. It is known that manufacturing plants produce according to their stock and the specific orders they receive. However, quantities and type of product are increasingly variable. In order to react to their customers’ wishes, concrete manufacturers have to change their production several times during a shift. However, this operation has a big impact on the production. On the one hand, the overall manufacturing process is affected in that the production changeover involves a production shutdown which adversely affects the rate of production. On the other hand, this operation affects the labour force during the handling of moulds, exposing them to hazards and frequent work-related accidents.
