Special fastening solutions

Material, form, manufacturing tolerances and similar requirements decide whether a special item can be manufactured using the cold- or hot extrusion process.

Special customer requirements can be addressed by special finishes or secondary operations either on standard products or specialty items:

• Customer-specific set
• Mechanical treatments like shortening, thread-cutting, drilling of fastening and split-pin holes, lathing of thin shanks and grooves
• Heat treatments
• Tribological dry coating Bossard ecosyn®-lubric
• Color coatings
• TufLok® grip coating
• Precote® adhesive coating
• Nystay® retaining ring / protection against loss
• Underhead seals Nyseal® and Nyplas®
• Nickel-Teflon-coatings
• Anodising
• Zinc-aluminium slat coatings (e.g. Geomet®)
• All kinds of zinc plating (incl. Cr(VI)-free coatings)

Turned- and milled parts

Materials

• All machinable steels
• Non-ferrous metals and plastic
• Many special-purpose steels

Quantities
From prototype to full production run, depending on part type and machine type.

Hot extruded parts

Materials

• All established materials including rust- and acid-resistant stainless steels
• Special purpose materials such as e.g. nymonic on request

Quantities
From prototype to product run.

Cold extruded parts

Materials

• Various steels
• Rust-resistant A2 and A4 steels
• Aluminium, brass
• Special-purpose steel and titanium on request

Quantities
Special-purpose steel and titanium cold extruded parts and multi-stage parts on request from about 50,000 items, depending on part shape and size.

Stamped- and bent parts

Materials

• All established steels
• Non-ferrous metals
• Rust-resistant A2 and A4 steels
• Alloys

Quantities
Individual items, small to large production runs depending on part geometry. Small production runs can also be cut with laser or water jet.

Bent strip parts

Materials

• All established steels
• Non-ferrous metals
• Rust-resistant A2 and A4 steels

Quantities
Small to large production runs depending on type and dimensions. Quantities are conditional on tools and depend on part geometry.
