If you're building a product that needs to meet exact specifications - in shape, size, function, or finish - then custom manufacturing services are the solution you’re probably searching for. 

You can design and produce exactly what you need, using the materials and processes that work best for your industry

These services are used by businesses that value precision, flexibility, and control over their designs and supply chain. 

In our opinion, the biggest advantage is knowing you’ll never have to force a generic part to fit a custom build; everything is made to work exactly as it should.

What Are Custom Manufacturing Services?

Custom manufacturing allows companies to produce made-to-order parts, components, or full products based on specific design, material, and quantity requirements.

This process involves taking your design - or helping you create one - and turning it into a real-world part using techniques like CNC machining, 3D printing, metal fabrication, or injection molding. 

You define the dimensions, tolerances, surface finish, and materials, and the manufacturer produces it accordingly. 

The end result? A part that matches your exact needs without compromise.

All of these services are handled by our team in a single streamlined process, giving you faster turnaround, clearer communication, and complete control at every step.

Choosing custom over standard options makes sense when:

• Your part needs to meet tight tolerances or special specs

• You can’t find anything suitable off the shelf

• You want to control quality, durability, or material choice

• Your application is mission-critical and can’t fail

• You’re building a new product or revising an old one

What’s Included in Custom Manufacturing Services

Custom manufacturing encompasses a wide range of materials, techniques, and industries, spanning from single prototypes to thousands of units.

Common Services You Can Access

Here are just a few services you’ll often find under the custom manufacturing umbrella:

Each method is chosen based on your needs for accuracy, cost, strength, or production speed.

Material Flexibility

You’re not limited to just steel or plastic. A quality provider can work with:

• Aluminum, stainless steel, titanium, brass

• ABS, polycarbonate, nylon, PEEK

• Exotic alloys and engineering-grade polymers

Your project gets matched with the right material for strength, durability, or appearance.

Types of Custom Manufacturing Services

The type of process you choose can impact cost, speed, and quality - here’s a breakdown of the most popular ones.

We offer all of these services in-house, so you can easily choose the right solution for your project without jumping between providers.

CNC Machining (Milling, Turning, and More)

CNC machining is a subtractive method where material is removed from a solid block using precise, computer-controlled machines. 

This process is ideal for producing tight-tolerance, repeatable parts.

• CNC Milling: Cuts materials using multi-axis rotating tools for complex parts

• CNC Turning: Spins the workpiece while tools shape it - perfect for cylindrical or symmetrical parts

• 5-axis and 3+2 setups for increased accuracy and complex geometries

Our shop is equipped with advanced CNC systems to handle both simple and highly complex projects efficiently.

3D Printing for Rapid Prototyping

3D printing (additive manufacturing) builds parts layer by layer from a digital file. 

While not always suitable for production-grade strength, it’s ideal for:

• Testing part fit or functionality

• Iterating design changes quickly

• Producing one-off or low-volume batches

You can print materials like PLA, ABS, nylon, and even metals like titanium or aluminum.

Injection Molding for Volume Production

Injection molding involves creating a mold and injecting melted material into it to form parts. It’s best for:

• High-volume production (1000+ units)

• Plastic enclosures, clips, caps, and precision components

• Maintaining consistent quality and surface finish

While mold setup is an investment, we help optimize the design for moldability, keeping your production costs low and your part quality high.

Why Custom Manufacturing Services Give You a Real Business Advantage

Let’s talk about the benefits that actually matter. 

Choosing custom manufacturing services can seriously impact how fast you grow, how well your product performs, and how much you end up spending over time.

Exact Fit and Function

If you’ve ever tried to “make it work” with off-the-shelf components, you know how frustrating and time-consuming that can be.

Share even the smallest details with your manufacturer. A 1mm mismatch can cost hours in rework.

Full Control From Start to Finish

With custom, you’re in charge of the specs. 

You pick the material, define the tolerances, and decide how the part should look and function. 

Need it heat-resistant?
Prefer a matte black finish?
Want to avoid sharp edges for safety? 

You decide - and the right manufacturer delivers. There’s no need to compromise because you're calling the shots.

Faster Prototyping and Production

Good custom manufacturing partners understand urgency. 

Once your design is approved, you can often get a prototype within days and a production run within a few weeks. 

That gives you a major advantage when you’re iterating quickly, testing in the field, or trying to get to market ahead of competitors.

Fun Fact: According to Forbes, you can design a simple fixture and have it printed in about 20 minutes using reinforced nylon, significantly speeding up the development cycle.

Cost Savings That Add Up Over Time

Yes, custom parts can cost more upfront. But think about the bigger picture. 

You avoid wasting money on parts that don’t fit, systems that constantly fail, or products you have to recall and revise. 

Custom parts reduce downtime, assembly issues, and field failures, which saves way more in labor and rework than you’d spend on initial production.

And here's something most people forget: custom doesn’t always mean expensive. 

For high-volume orders, your cost per part can drop significantly, especially with CNC machining or injection molding, where setup is a one-time investment.

How to Choose the Right Custom Manufacturing Partner Without Regret

Finding a manufacturer isn’t hard, but finding the right one can make all the difference between a smooth project and a production nightmare. 

Here's how to filter out the noise and partner with someone who can actually deliver what you need.

Make Sure Their Capabilities Match Your Project

Don’t assume every shop can handle your design. Ask specific questions:

• What types of CNC machines do they use?

• Can they handle multi-axis machining, complex geometries, or tight tolerances?

• Do they specialize in metals, plastics, or both?

Choosing someone who isn’t equipped for your project leads to missed specs, delays, and do-overs. 

That’s why we’ve invested in both the equipment and expertise to handle everything from simple parts to advanced, high-precision builds - so you don’t have to shop around.

Ask for Samples, Case Studies, and Proof of Work

Any serious manufacturer should have real examples to back up their promises. Look for:

• Detailed case studies or client success stories

• Sample parts or test pieces (bonus if they’re similar to your project)

• Before-and-after photos, tolerances achieved, or material specs

This shows not just what they can do, but what they’ve actually done.

Prioritize Clear, Proactive Communication

Your first few emails or calls will tell you everything. 

Are they asking the right questions?
Do they flag potential design concerns?
Or do they just send a quote without digging deeper?

Custom manufacturing requires collaboration. 

If they’re not engaged now, they won’t be later when you hit a snag. Communication gaps lead to production delays, misaligned expectations, and costly mistakes.

Dig Into Their Quality Control Process

Ask how they ensure quality before anything ships. Top-tier providers use:

• In-process inspections and final part validation

• Precision measuring tools (like CMMs or laser scanners)

• Formal certifications, like ISO 9001 or AS9100

Even if your part isn’t aerospace-grade, strong QA systems mean better consistency and fewer surprises.

Even if you're not building a satellite, consistent parts matter. We’ve put strict inspection processes in place so that what you receive always matches what you approved.
