From Fabricated Parts to
Fully Assembled Products
At Fabwest Manufacturing, we don’t just build parts — we build finished products. Our in-house mechanical assembly turns laser-cut, formed, and welded components into complete, production-ready units that are market-ready.
No outside vendors. No hand-offs. No downtime waiting for parts to arrive.
Just one team delivering a smooth, predictable workflow from start to finish.
Continuous-Flow Assembly That
Eliminates Lag Time
The benefit of centralizing your product fabrication AND assembly in our Temecula facility, is that your project moves through the shop as a continuous process, not a long batch cycle.
Instead of waiting for an entire batch of welded parts to be completed, packed, shipped, and staged elsewhere before assembly can begin, our team starts assembling units immediately as they move out of welding.
That means:
- No production stalls
- No freight delays
- No bottlenecks created by shipping parts to another company
- Faster time to market
- Better schedule reliability
This lean, integrated flow is a strategic advantage our customers leverage.
Integrated Assembly for
Sheet Metal and Machined Parts
With fabrication, finishing, and assembly under one roof, your parts transition smoothly from one step to the next. This reduces handling errors, preserves tolerances, and shortens lead times.
Our in-house capabilities include:
- Subassemblies and full product builds
- Hardware installation: PEMs, standoffs, fasteners, and inserts
- Line graining, deburring, edge finishing
- Tapping, countersinking, and counterboring
- Seamless coordination with powder coating, plating, and silk-screening
You get precise assemblies that fit and function exactly as intended — without the typical delays of multi-vendor production.
One Team,
One Workflow, One Finished Product
By keeping the entire build process under one roof, we eliminate the weakest parts of traditional supply chains: vendor coordination, freight timing, miscommunication, and inconsistent tolerances.
The result:
- Fewer handoffs and virtually no waiting between stages
- Consistent quality across cutting, forming, welding, and assembly
- Faster turnaround and production-readiness
- Lower freight costs and fewer packaging/handling risks
- Clear accountability and a single point of contact
From the first cut to the final inspection, your build moves through a streamlined, high-quality workflow.

FAQs: Welding Services
-
What types of mechanical assemblies do you handle?
We build everything from subassemblies and enclosures to full product builds for aerospace, electronics, and medical manufacturing.
-
Do you install fasteners and hardware?
Yes. We install PEMs, standoffs, and other common hardware during final assembly.
-
Can you perform finishing after assembly?
Yes. We can handle powder coating, silk screening, and plating either before or after assembly, depending on your project’s needs.
