Waltec’s press-blow machine is the consequent further development of the conventional process, where high-quality hollow glasses are produced by pre-forming, pre-pressing and blowing, both in rotation blown-ware operation and in non-rotation blown-ware operation.
Contrary to the well-known machine concept, where the process movements, such as pre-pressing and others, are realised pneumatically, Waltec has replaced the pneumatic drives, by the latest servo technology in all ranges. This means all movements of pressing plungers, pre-mould and article support are realised with servo technology. For the first time, the press-blow process becomes transparent, can be controlled exactly and is reproducible. All movements have a very high repeat accuracy, resulting in high process stability.
WALTEC met the requirements of the market for bigger products. Its machine is fit to produce articles with maximum dimensions of 160 mm diameter and 350 mm height.
