Should I choose one supplier for machining and assembly?

The benefits of one stop shop solutions for CNC machining, finish and assembly

Assembly - preparation

Imagine this: you've finally sourced the perfect machined parts for your project. They're exceptional quality and they were delivered on time. But then reality hits – those beautiful components require fiddly assembly, and you haven't factored in the extra time and hassle of finding another reliable supplier.

If this is your reality, you’re not alone. I often talk to potential customers about their buying habits and the difficulties they are currently facing in their buying process. Buyers and engineers often tell me variations on the above story.

Coordinating multiple suppliers can often leave them with gaps in their project timeline which can be costly and stressful. Not to mention how time-consuming it can be to find multiple reliable suppliers and then liaise with each individually. This can be particularly frustrating when it comes to small, fiddly assemblies.

An additional complication when dealing with multiple suppliers for machining, finishing, and assembly is when there is a small delay with one supplier, which happens from time to time. What can seem like a small delay can have a knock-on effect on other suppliers.

You may have been here before. You lose your allotted slot with one supplier which leads to further delays and associated costs. This situation needs careful management which can be stressful and time-consuming.

So what’s the solution?


Choose a one-stop shop

Choosing a one-stop shop for your machined components can eliminate time-consuming hands-on processes.

Everything can be handled by a single supplier: material sourcing, help with machining design, machining, plating and other finishing processes, inspection, certification, and even assembly.

What are the benefits of a one-stop shop machining supplier?

The benefits of choosing a one-stop-shop supplier are substantial.

Consolidating your machining and assembly needs with a single supplier can save you time and effort. You’ll spend fewer valuable hours researching, comparing quotes, and coordinating logistics with different companies.

It’s also likely you will have a single point of contact which will simplify communication and project management. You’ll easily be able to track your project progress, address any concerns, and ensure everyone is on the same page.




One element that cannot be underestimated is the potential to mitigate the risk of errors, delays, and quality issues that can arise when working with multiple vendors. Imagine the peace of mind that comes with this!

You can often negotiate better pricing and reduce overall costs compared to dealing with multiple vendors. Additionally, you'll save on shipping and handling expenses by having all services provided by a single supplier.

Ultimately, choosing a single supplier for machining your parts, assembly, and other secondary processes can help you to build a long-term relationship with a single supplier that fosters trust and collaboration. You’ll be able to benefit from increased flexibility and scalability to meet the ever-evolving needs of your projects.
