The Problems We're Built to Prevent
Generic machine shops treat a cryogenic mount like any other bracket. These are the mistakes that result when they do.
Thermal Contraction
Parts machined at room temperature shift out of spec at millikelvin.
Aluminum contracts roughly 4mm per metre between 300K and 4K. A supplier who ignores cryogenic thermal contraction delivers parts that fit on the bench and fail in the fridge.
We review material selection and dimensional allowances for cryogenic contraction during DFM — before manufacture begins.
Magnetic Contamination
Standard alloys introduce magnetic noise that destroys qubit coherence.
Superconducting and trapped-ion qubits are extremely sensitive to stray magnetic fields. Standard stainless steel grades, tooling residue, and incorrect platings are all sources of magnetic contamination most shops never consider.
We flag high-magnetic-susceptibility materials and specify low-susceptibility alternatives during DFM review.
UHV Incompatibility
Standard machining lubricants and surface treatments contaminate ultra-high vacuum environments.
Parts that look clean on arrival outgas in vacuum and raise chamber pressure by orders of magnitude. Standard anodize is porous and traps volatiles. Most shops don't know the difference between electropolish and standard polish for UHV applications.
We specify electropolish, vacuum bake requirements, and UHV-compatible surface treatments for every quantum hardware order.
Our Process
How a Quantum Hardware Order Works at Factorem
From STEP file to delivered part — with quantum-specific engineering review at every stage.
1
Upload STEP File + Drawing
STEP, IGES, or 2D drawing accepted. Include operating temperature range, surface finish callouts, and any assembly context. Quote returned within 24–48 hours. NDA available on request.
2
Engineering DFM — Quantum-Specific Review
Your dedicated engineer reviews material selection, thermal contraction allowances, magnetic susceptibility, and UHV compatibility — not just whether the part can be machined. Issues are flagged before a single chip is cut.
3
Material + Finish Selection Confirmed
We confirm alloy grade, surface finish type (electropolish vs. standard), vacuum bake requirements, and any plating spec before order confirmation. No assumptions — everything documented in the work order.
4
Manufacture + In-Process QC
5-axis CNC machining with in-process dimensional checks. CMM inspection on critical features. Surface finish and electropolish quality verified at source — not on arrival at your lab.
5
Delivered with Full Documentation
Dimensional inspection report, material certificate (EN 10204 3.1), surface finish confirmation, and Certificate of Conformance ship with every order. 12-day standard lead time. Tracked to your door.

FAQ
Common Questions from Quantum Teams
Can you manufacture parts for dilution refrigerators?
Yes. We manufacture cryogenic mounting plates, thermal shield components, wiring fixtures, and mixing chamber hardware for dilution refrigerator systems. Our engineers review material selection for cryogenic thermal contraction during DFM before manufacture begins.
What tolerances can you achieve for cryogenic quantum hardware?
We hold tolerances to ±0.005mm on critical features. For cryogenic parts we review dimensional allowances for thermal contraction to millikelvin temperatures during DFM — so the part fits at operating temperature, not just at room temperature.
Do you understand UHV and outgassing requirements?
Yes. We specify electropolish, vacuum bake requirements, and UHV-compatible surface treatments as part of every quantum hardware order. Standard machining lubricants and porous anodize types that outgas are flagged and replaced during DFM review.
What materials do you use for cryogenic quantum hardware?
Common materials include AL 6061, OFHC (oxygen-free high-conductivity) copper for thermal conductivity, SS 316L for vacuum chambers, PEEK for low-thermal-conductivity wiring fixtures, and mu-metal for magnetic shielding. We flag materials with high magnetic susceptibility during DFM.
Can you manufacture RF cavity housings and ion trap components?
Yes. We manufacture RF cavity housings, microwave shielding enclosures, and precision housings for ion trap systems. Our engineers review RF cavity dimensions, surface finish requirements, and UHV compatibility during DFM before production begins.
What documentation ships with quantum hardware orders?
Every order ships with a dimensional inspection report, material certificate (EN 10204 3.1), surface finish confirmation, and Certificate of Conformance. First Article Inspection reports are available on request.
