Atotech gains Volkswagen TL 180 approval
Atotech Deutschland GmbH, based in Berlin, Germany, has recently gained Volkswagen TL 180 approval with its zinc flake system Zintek®
he new Volkswagen TL 180 specification requires a Cr(VI)-free black zinc flake coating with high corrosion protection for automotive parts. This coating is typically used on small, bulk processed threaded fasteners. Since the zinc flake technology presents no risks of hydrogen embrittlement, the coating is also suited for high tensile fasteners.
Automotive industry’s expectations and requirements are particularly high when it comes to finishes appearances. As regards to
black finishes, uniformity and long-term stability of the colour are among the main issues of concern. In addition to that, the TL 180 specification also requires excellent corrosion resistance, constant friction values and very good heat loosening properties. With its zinc flake system Zintek®
Atotech’s unique black base coat Zintek® 300 B with specialised Techseal® Black system provides a Black system also successfully passed TL 180 corrosion
Black, Atotech has met such challenging demands and gained the TL 180 approval. Combining Black top coats, the Zintek®
uniform deep black appearance with no silver shine through even after handling. Furthermore, the system meets Volkswagen’s friction values window and boasts excellent heat loosening properties. The Zintek®
protection requirements: 720 hours without red rust and 240 hours not exceeding the S1 classification according to DIN 34804.
Drawing on experience
MANFISA, a Spanish company based in Irurtzun, Navarra, has been a specialist in aluminium wire
drawing and casting maker since 1973, gaining an experience that has enabled it to develop a wide range of highly productive wires.

ANFISA draws pure and aluminium alloys in a variety of diameters from 0.8mm to 10mm, suitable for mechanical and electrical applications as fasteners, nails, rivets, screws, bolts, nuts,
he GW 161-HXL flat die thread rolling machine is capable of threading parts with up to 800mm shank length and thread lengths of 350mm. It will primarily be used in the production of wood and construction type fasteners with diameters
between 7mm and 16mm. Features of the smaller machines are also incorporated on this
new truly large machine. Hydraulic die carrier clamping as well as diameter adjustment is made from the touchscreen operator panel. So is the height adjustment of the rails and feeder console. To facilitate die change and setup the reinforcing bar across the
die area can be moved out of the way electrically by simply pushing a button. And even on this big machine, with its high power 95kW drive, die match can be set while the machine is running parts. All these features were developed by EWMenn and can be installed on the current models.
