Project we have moulds sized 100 ml , 200 ml , 375 ml and 500 ml . The moulds are changed on the machines depending on orders ,” says Mashego .
The number of bottles produced per day or week varies with the size and type of the bottles , with different numbers of cavities depending on different sizes of bottles – for instance , six cavities for a 500 ml bottle every 18 seconds per cycle ; compared to eight cavities for 200 ml bottles in 12 seconds per cycle . The smaller the bottles , the faster the cycle time . The facility can produce 200 bottles per hour for more than 100 000 bottles a week . Off-cuts and reject bottles can be immediately recycled on site .

“ The machines need to attain the requisite temperature before they can start producing the bottles and caps . The temperature is controlled by the chiller , which has a compressor that regulates the water-cooling system . The chiller has an input and an output for the water . The input water comes from the chiller at a fixed temperature , say 15 ° C . The output water goes back to the chiller after passing through the machine . The output water temperature depends on the machine temperature . If the output water is too hot or too cold , the chiller activates the compressor to balance it . The compressor switches on and off as needed to maintain a stable temperature ,” he says . RACA One of the Arburg bottle plants .
