Magnets for assembly and production
In assembly and production you use magnets to position workpieces, change moulds and jigs quickly and fix parts temporarily. Pot magnets with countersunk hole, threaded stud or internal thread are built into moulds and workbenches; small magnets are processed faster with a dispenser.
Short answer: in assembly and production you use magnets to position workpieces and parts, change moulds, jigs and templates quickly, and temporarily fix steel parts during gluing, welding or measuring. Usually you build pot magnets with a countersunk hole, threaded stud or internal thread into a mould or workbench. For products that contain magnets themselves, a magnet dispenser speeds up placement.
Applications and advice
| Application | Advice |
|---|---|
| Interchangeable moulds and templates on a steel table | countersunk pot magnets in the mould |
| Stops and locating pins | pot magnets with threaded stud or internal thread |
| Holding parts on painted or delicate surfaces | rubber pot magnets |
| Placing small magnets in a product | dispenser + marked poles; see how do you mount a magnet? |
| Removing metal particles from a flow | filter magnets |
What to watch out for?
- Position by shape, force by magnet: let pins or edges determine the position and the magnet only provide the attraction. That keeps the accuracy constant.
- Chips and dust: magnets attract steel chips. Keep contact surfaces clean; a dirty surface costs a lot of force.
- Welding: magnets can deflect the welding arc and get too hot above 80 °C. Keep them away from the weld. See magnets at high temperatures.
- Safety: pot magnets can pinch fingers. See working safely with magnets.
Series production and custom work
If there is a magnet in your own product, fixed sizes, marked poles and packaging with spacers help keep assembly fast. For non-standard sizes or larger series: see custom-made magnets.
