Sheet metal fabrication of electronic enclosures always requires precision, partly to ensure that all the elements meet correctly for assembly, but also to ensure that mounting points and threaded connectors are in exactly the right position. Even very small positional errors make it impossible to securely attach components and circuit boards without the risk of damage or distortion.
How are threaded connectors used in sheet metal fabrication?
The image above shows a sheet metal plate that is designed to make a sandwich of sheet metal plates with spaces formed by threaded barrel connectors of exactly uniform size. Sheet metal fabrication of this type of structure enables easy assembly using bolts, but only if the locations of the threaded connectors are very precise and the alignment between the metal sheets is perfect. Any misalignment or variation in the depth of installation of the barrel connector will result in gaps and distortion of the finished sheet metal enclosure.
What are important considerations for fitting threaded connectors to sheet metal enclosures?
It is vital that the holes for the threaded connectors are cut with very high precision when fitting threaded connectors to sheet metal enclosures. This is especially important with small diameter connectors and for connectors that will be used to mount delicate components, like circuit boards used for sheet metal fabrication of metal enclosure boxes for electronics.
Sheet metal fabrication requires high precision punch cutting and bending to ensure correct placement of mountings
Taiwa uses Japanese AMADA CNC punch laser cutting machines that ensure all mounting holes, slots and tabs are perfectly cut. Our bending and forming machines are also manufactured by AMADA, and have sophisticated spring-back calculation integrated into their CNC control systems. This enables pre-analysis and pre-bend prediction of the exact amount of additional bending required during sheet metal fabrication to ensure that the result is perfectly aligned after the sheet metal springs back after forming.
Riveting of threaded barrels into sheet metal parts by experienced operators
Not everything relies on computer controls, the riveting of threaded barrels into sheet metal parts is done by our experienced technicians. In the image above you can see how alignment is verified by the operator before the threaded barrel connector is inserted in the metal blank.
A hydraulic press is used to rivet the threaded barrel connector into place
Using a high quality, bespoke, hydraulic press ensures that when the operator rivets the threaded barrel connector into place during the sheet metal fabrication process that all threaded barrel connectors are level, with exactly the same positional characteristics as each other. This contributes to ensuring that final assembly is gap-free and offers even support to components and circuit boards.
