A quick rule:

Choose SLS Nylon when you need fast turnaround, complex geometry, low to mid-volume production, or frequent design changes.

Choose injection molding when the design is stable and the volume is high enough to justify tooling.

At Unionfab, SLS Nylon is one of our key processes, supporting functional prototypes, bridge production, and custom nylon parts with multiple PA12, PA11, TPU, and glass-filled material options.

3 Real-World Proofs for Choosing a CNC Machining Partner

Looking for a CNC machining partner you can truly rely on? With so many options, it's hard to know who delivers on their promises. At Unionfab, we back our precision CNC machining services with real results. Here are three case studies that show why global engineers trust us for their most demanding projects.

1. German Automation Line (48hr Prototype)
A 15-piece low-volume batch of multi-station sensor brackets for automotive assembly lines. Delivered a 1-piece prototype in just 48 hours with no MOQ. Overall flatness controlled within 0.05mm using modular quick-change tooling. The result: zero vibration displacement for 24/7 production, engineered for over 8 years of continuous operation.

2. Canadian Lightweight Robot Arm (35% Weight Reduction)
A 50-piece run of joint connection components for a six-axis collaborative robot. Multi-axis hole true position held to ±0.0005", flawless 1.5mm thin-wall milling from Aluminum 7075-T6, verified by full CMM inspection. Achieved 35% weight reduction while maintaining extreme torsional rigidity.

3. US Medical CT Scanner Mount (10+ Year Life)
Transmission fixing base and pilot alignment mount for servo drives. Applied reverse dimension compensation in CAM programming before anodizing to prevent thread seizure, plus manual Go/No-Go gauging. Perfect coaxial alignment eliminated drivetrain noise and vibration for over 10 years.

Why Unionfab?
- ISO 9001:2015, ISO 13485:2016 certified
- 400+ CNC machines (3-axis, 4-axis, 5-axis)
- Tolerances down to ±0.0002" (0.005mm)
- 80,000m² factory, 100+ R&D engineers
- No MOQ, fast turnaround from 1 day

From Prototype to Production: How Unionfab’s Precision CNC Machining Delivers on Your Custom Parts

Looking for a CNC machining partner that can handle your custom parts from prototype to production without the headache of high MOQs or long lead times?

At Unionfab, we understand that every project is unique. Whether you need a single prototype or a low-volume production run, our precision CNC machining services are built to adapt. With over 400 CNC machines including 3-axis, 4-axis, and 5-axis machining centers, we can tackle complex geometries and tight tolerances down to ±0.0002" (±0.005mm).

We recently worked with an intelligent robotics developer in Canada to produce 50 pieces of joint connection components for a lightweight six-axis collaborative robot arm. Using our 5-axis CNC machining and Aluminum 7075-T6, we held multi-axis hole true positions to ±0.0005" and achieved a 35% reduction in arm weight while maintaining extreme torsional rigidity. Full CMM inspection reports were provided for every part.

Another case involved an industrial automation integrator in Germany needing multi-station sensor brackets for automotive assembly lines. With no MOQ and a 48-hour lead time, we delivered 15 prototype pieces with overall flatness controlled within 0.05mm — zero vibration displacement on the line, ensuring 24/7 uptime.

Our quality control goes beyond specs: 100% dimensional and surface inspection, form tolerances, burr & sharp edge checks, thread go/no-go gauging, and internal defect inspection. We are ISO 9001:2015 and ISO 13485:2016 certified, and we offer OEM customization for dimensions, materials, tolerances, finishes, and logo engraving — all with a minimum order quantity of just 1 unit.

ISO-Certified Precision CNC Machining: Your Guarantee for Quality

Choosing a CNC machining partner can be tricky – especially when you need to prove your parts meet the highest standards. That’s why certifications matter more than ever.

At Unionfab, we don’t just talk about quality – we back it up with globally recognized certifications:
✅ ISO 9001:2015 (certificate 11326Q00568R201) for our entire custom manufacturing service, covering CNC machining, rapid prototyping, and low-volume to high-volume production.
✅ ISO 13485:2016 (certificate 381230229R0S) for medical device quality – crucial for healthcare and life-science applications.
✅ ISO/IEC 27001:2022 (certificate 08925I20619ROM) for information security, ensuring your designs and data stay safe.

These certifications aren’t just paperwork – they mean every part we machine, from aluminum enclosures to stainless steel medical components, follows strict quality control and traceability systems. Our in-house CMM inspection, surface roughness measurement, and 100% dimensional checks are all part of the routine.

Whether you need a single prototype or 150,000+ units per month, you can rely on a certified CNC machining company that puts quality first.
