Milling and drilling
When processing plastic enclosures, it is essential that the tools be cooled only using oil-free air. Drilling, cooling and lubricating methods can all lead to stress cracks.
If silicone-based lubricants are used, then a downstream printing process is not possible due to the poor adhesive properties of the lacquer. If cases of doubt, we would be pleased to provide specific information.
When working with our milling machines and planning to make openings, you are advised to apply a general radius of 1.5 mm.
NB: Our processing service excludes any such risks.
When punching out plastic parts, crack formation and stress whitening at the corners can never be ruled out. The BOPLA processing service minimizes any such risk.
The quality of any adhesive connection depends on the materials being glued, the size of the area to be glued and the glue itself.
Make sure to observe the following ...
- Only glue parts made of the same materials.
- Aim for a glueing area as large as possible.
- Use suitable glues only. Observe any technical instructions.
- Before serial production, test the adhesive connection under operating conditions such as temperature, load etc.
NB: Our services are subject to our General Terms & Conditions.
Please make sure that all residues of any coolants or lubricants used in machining are removed if plastic parts must be attached to aluminium enclosures (e.g. plastic cable glands, adapters, plugs, etc.). Coolants and lubricants can cause plastic parts to become brittle and split. Also, remember that when aluminium castings are machined, enclosed air bubbles, known as shrinkage holes, can be revealed. The casting process and alloys we use result in very few shrinkage holes.
