What we machine to
Six features that define the housing
Send the drawing or the old housing. These are the features we machine to.
- Seat or cavity The bore, pocket or seat the component sits in, and its fit.
- Datums The reference faces that line the component up with the machine.
- Mounting faces and bolt pattern Where and how the housing fixes to the machine.
- Threads or inserts Threads cut into the plastic, or threaded inserts for a stronger, reusable thread.
- Cover and sealing face A removable cover, and the face it seals against.
- Openings Cable, tube or access openings, and their positions.
Fits and critical locations come from your drawing. We confirm them with the quote.

Materials for housings
Common choices, and why
- Acetal Stiff, dimensionally stable and low in moisture uptake, so a close seat holds.
- Polycarbonate and acrylic Clear, so you can see inside. Some cleaners can craze them, so tell us what you use.
- PP, PVC, CPVC and PVDF For wet and chemical areas.
- PEEK and ULTEM Heat and dimensional stability.
- Nylon Tough. It takes on moisture, which we allow for when machining.
- UHMW As a replaceable low-friction insert inside the housing.
- Aluminum, brass and bronze When a metal housing suits the job.

Not a housing?
What does yours do?
Mounting and enclosure parts are easiest to name by their job. We machine almost any plastic part, so if yours isn’t here, describe it in a quote request.
