Some shower hardware parts look simple but fail in the field because the hole is 0.1 mm off, the thread binds, or the clamp doesn’t seat. That is where CNC machining earns its place. Zimmor runs multi-axis CNC centers for the components where fit and finish cannot be left to chance — and we pair them with die-casting where volume favors it, so you get the right process per part.
What CNC Machining Covers
- ✓
Multi-axis milling and turning of brass, stainless steel and aluminum fittings
- ✓
Tight-tolerance components — hinge bodies, clamps, adapters, custom brackets
- ✓
Prototype and low-volume runs where tooling for die-casting isn’t justified
- ✓
Complex geometries that casting can’t cleanly produce
- ✓
Secondary operations — threading, drilling, engraving under one roof
How We Decide CNC vs Die-Casting
Not every part should be CNC’d. The rule of thumb:
- •
Choose CNC when tolerances are tight, volumes are low–mid, or the shape is complex.
- •
Choose die-casting when volumes are high and the geometry allows it, to cut unit cost.
Our engineers make this call during DFM so you don’t pay for precision you don’t need — or lose fit because you skipped it.
Why Zimmor for CNC
- •
Owned machine shop (not subcontracted)
- •
Tolerant to ±0.01–0.05 mm depending on feature
- •
Material verification before cutting (spectrometer on incoming stock)
- •
Direct hand-off to finishing and QC in the same plant

Frequently Asked Questions
What is your minimum CNC batch?
From a single prototype to production runs. There is no hard minimum — small batches are exactly what CNC is good at, which is why we use it for sampling and low-volume custom parts.
Can you machine complex or thin-wall shapes?
Yes. Multi-axis centers handle complex geometry and thin walls that die-casting struggles with. Send the model and we’ll tell you what’s feasible.
How do you verify tolerance?
Incoming material is spectro-checked, first articles are inspected against the drawing, and in-process checks run at each station. Critical dimensions are measured before release.
