CNC Forming

fanned_formed_parts-300x200-300x200
  • Highly efficient and repeatable means of bending parts
  • Critical machine parameters (e.g. depth of bend, amount of pressure required and bend order) are stored for future runs to ensure consistency
  • The use of multiple bend radii in the same part will require additional set up time and increase cost. Whenever possible, use the same bend radius for all bends throughout the part.
  • It is highly advisable to show dimensions on a drawing in the formed view as opposed to the flat pattern view (if applicable). This will help to reduce or eliminate misunderstandings about how the dimension should be applied.
  • Holes positioned near bend lines are prone to distortion as the nearby material stretches and compresses. Ideally, holes should be kept as far from bend lines as possible but if a close proximity is necessary, request that the hole be reamed after forming to re-establish its original shape.

Welding

* spot welding not available for aluminum
  • Welding introduces a lot of heat and has the potential to cause deformation. It is advised to specify the specific locations and intervals at which weld is required and to keep those a sparse as can be tolerated for your application in effort to minimize the potential of heat-related deformation.
  • Microform does not specialize in welds on cosmetic materials such as #4 or #8 finish stainless steel.
  • All of Microform's fabrication services including weld are in-house only. Installations or other on-site processes cannot be provided

Hardware Insertion

hardware-2-300x200
  • Adds additional depth for load bearing threads to sheet metal parts
  • Fast, generally simple process helping to control cost
  • Utilizes existing holes cut by high precision cutting machine such as a laser or water jet which increases the precision of the fasterner's location
  • Where comparable in function, self-clinching hardware will typically be superior to weld studs both in accuracy of location and in strength.
  • Fasteners may be forced out particularly if load comes from the insertion side. To reduce the risk of separation, it is best to specify the side of installation as that opposite of the load wherever possible.
  • Self-clinching fasteners are best suited for areas of infrequent use. Areas of anticipated frequent use such as a nut that will have a screw put in or taken out as a part of standard operation, will be prone to loosening with time. In those cases, self-clinching hardware is still an option but it would be advisable to request the addition of 2-3 tack welds to reinforce the fastener.
  • Most self-clinching studs and standoffs will have an exposed head on the surface opposite the threads. If this is undesirable (e.g. for cosmetic purposes), it is advisable to request the addition of weld to conceal the fastener head
