Contract manufacturing and job order production

Irre­spec­ti­ve of the incre­asing importance of other pro­ces­ses, such as plas­ma, laser and water jet cut­ting, the­re is, eco­no­mic­al­ly spea­king, no alter­na­ti­ve to oxy-fuel cut­ting for thi­c­ker mate­ri­als up to 600 mm. This appli­es in par­ti­cu­lar, when the cut­ting qua­li­ty, a pos­si­ble work­pie­ce dis­tor­ti­on due to hig­her heat input and the har­dening ten­den­cy of the mate­ri­al are not decisive.

The opti­mum tech­ni­cal equip­ment ensu­res fla­me cut­ting to DIN at a high cut­ting qua­li­ty. This means that seri­al parts can be cut with up to four tor­ches simul­ta­neous­ly. Moreo­ver, a direct trans­fer of the customer´s CAD data takes place, which saves time and redu­ces sources of error to a minimum.

The post-tre­at­ment of com­pon­ents can fur­ther impro­ve their mate­ri­al pro­per­ties. Stress reli­ef anne­al­ing signi­fi­cant­ly redu­ces inter­nal stres­ses cau­sed by ther­mal and mecha­ni­cal machi­ning pro­ces­ses, while sand­blas­ting remo­ves lay­ers of rust and sca­le. This opti­mal­ly pre­pa­res sur­faces for pri­ming, pain­ting or pow­der coating.

The metal-phy­si­cal pro­cess of vibra­ti­on stress reli­ef redu­ces resi­du­al stres­ses resul­ting from wel­ding and thus sta­bi­li­zes the work­pie­ces. This pro­cess, in which the work­pie­ces are sub­jec­ted to vibra­ti­ons at spe­ci­fic fre­quen­ci­es, has con­sidera­ble advan­ta­ges over con­ven­tio­nal stress-reli­ef anne­al­ing in terms of appli­ca­bi­li­ty, speed and cost. Moreo­ver, using this pro­cess it is also pos­si­ble to increase the fati­gue strength of work­pie­ces that are too lar­ge for the anne­al­ing fur­nace due to their dimensions.
