Threading & finishing

In order to ensure an optimised final product, several post-processing phases are often required. We have extensive knowledge and solid experience with each individual phase and how they interact in combination with each other. Below is a selection of the post-processing steps that can be carried out at Wulkan.

  • threading screws M3 - M20
  • knurling / thread rolling
  • special threads inch, stainless and Taptite
  • special machines for groove turning, drilling, internal threading, slot milling
  • own machinery for two-pointed rivets.
  • SEMS screw machinery (integrated washers)
  • Vision inspection equipment for optimal control
  • washing solvents from items
  • temperature-agitation process with detergent that purifies the items
  • annealing.
