On request ZOLLERN ISOPROFIL will supply not only profiles,but also finishedcomponents which are ready for use.We carry out machining,heat treatment and surface treatment operations.By arrangement we will supply your profiles in whatever condition you wish.The seat belt pivot in the illustration for example is quenched and tempered after machining.It is the galvanised and chromated to protect against corrosion. > In addition to the usual sawing or shearing of profiles we are able in our Herbertingen works to carry out not only conventional turning,drilling,milling and grinding,but also all further...

Heat treatment gives the material specific properties for its use or further processing. ZOLLERN ISOPROFIL has annealing facilities which can be used to carry out all forms of heat treatment on steel profiles in-house.The various processes of heat treatment are as follows: 1011 > Here the metal is heated up to the Ac1transformation point at about 720 C.Sub- sequent slow cooling produces a soft, stress-relieved state.Simultaneous conver- sion of the carbides into spheroidised form significantly improves subsequent machining or chipless cold forming. Normalising comes about through heating above...

General Induction Treatment: > ZOLLERN ISOPROFIL has extensive expe-rience hardening steel profiles.As well as hardening the special profiles from our own factories,we will process standard shapes, rectangular or square sections and tubes on a sub-contract basis. > Inductive case hardening > Inductive through hardening > Inductive quenching and tempering > Induction Hardened Steel Profiles Hardened area (only the dark areas have been hardened): The martensitic structure in this area is characterised by highest wear resistance.Unhardened area (light-grey area):all positive properties of the steel...

Induction hardening machine to harden cold drawn steel profiles with cross sections of up to 4000 mm 2 andspecified lengths from 2200 mm up to 9000 mm. Effective hardening depths of 0.5 up to 5.0 mm are possible. As well as hardening the ZOLLERN steel profiles,we will also process on sub-contract basis. 1213 Application Examples: Linear guides,transmission system components,torsion bars,splined shafts, chain guides,knife blades,spring mechanisms,etc. Induction Hardening provides technical and cost advantages over conventional methods: > Induction Hardened Profiles can be in lengths of up to 9000...
