The prototype works, but it is hand-built
Simplify parts and interfaces, choose credible processes and reduce one-off assembly behaviours that will not scale.
Manufacturing support & DFMMove from “it works” to “we can make it.”
A working prototype is an important milestone, but it is not automatically a production design. Twocan helps develop products towards repeatable manufacture through design for manufacture, tolerances, drawings, process selection, supplier engagement and practical build feedback.
Prototype ≠ productionThe next stage is about reducing avoidable complexity and turning a one-off build into something suppliers can repeatedly understand and make.

Start with the problem
When manufacturing support becomes useful
Manufacturing decisions become more expensive as tooling, inventory and supplier commitments increase. The goal is to resolve avoidable issues while change is still relatively cheap.
Suppliers cannot quote confidently
Improve drawings, tolerances, specifications and manufacturing assumptions so suppliers understand what is actually required.
The design is too expensive or complex
Review processes, part count, material, assembly and tolerances to identify practical cost-down opportunities.
We need engineering support through first builds
Respond to supplier questions, resolve fit and assembly issues and update the design as manufacturing feedback arrives.
Relevant work · CS Platforms
Design carried through suppliers, assembly and test.
The Ceilingsurf upgrade did not stop at CAD. Twocan produced technical drawings, coordinated suppliers, checked parts for fit during the build, managed assembly and integration, and fed practical issues back into the engineering.
That closed loop helped deliver the upgraded working prototype on the required programme rather than leaving the client to bridge the gap between design files and physical hardware.

How we work
Prepare the design for the way it will actually be made.
DFM is not a final checkbox. It is a series of engineering decisions about process, tolerance, assembly, inspection, supply and cost as the product matures.
Review the design
Identify one-off prototype assumptions, difficult features, tolerance risks and unclear manufacturing intent.
Choose processes
Match geometry, material, quantity, finish and commercial needs to credible manufacturing routes.
Develop detail
Update CAD, interfaces, fasteners, tolerances and drawings around the chosen processes.
Engage suppliers
Support RFQs, answer technical questions and use supplier feedback to improve manufacturability.
Learn from builds
Capture first-off, assembly and inspection issues and feed them back into controlled design updates.
Not every project needs every stage. We scope around the next useful decision and the evidence needed to make it.
Why Twocan
Engineering support that stays involved when parts become real.
A supplier drawing is not the end of product development. Early manufacturing feedback is often some of the most useful engineering information a project receives.
◎
Design + manufacture together
DFM decisions remain connected to the product function and engineering intent.
◇
Supplier communication
We can translate between design intent and the practical questions manufacturers need answered.
△
Tolerance discipline
Critical interfaces get the attention they need without over-tolerancing everything by default.
→
First-build feedback
Fit, assembly and supplier issues can be resolved through controlled CAD and drawing updates.
Manufacturing feedback belongs in the design loop.
On the CS Platforms prototype upgrade, Twocan carried engineering decisions through technical drawings, supplier coordination, assembly, integration and physical testing — using build feedback to resolve issues before final assembly.

Common questions
Useful answers before the first call.
If your project does not fit neatly into one of these questions, that is normal. Early engineering work is often about clarifying the problem before deciding what work package makes sense.
When should design for manufacture start?
Manufacturing should be considered from early development, but the level of DFM detail should grow with design maturity. There is little value optimising an unproven concept for mass manufacture too early.
Can you help us find or work with suppliers?
Yes. We can support supplier engagement, quotations and technical communication, and help respond to manufacturing feedback as the design develops.
Can you produce manufacturing drawings?
Yes. We can create and update technical drawings, dimensions, tolerances and notes appropriate to the intended manufacturing route.
Can you help reduce production cost?
Potentially. Cost-down can involve process choice, part count, material, assembly time, tolerance strategy and supplier feedback. The useful opportunities depend on the specific product and volumes.
Does DFM mean the product is ready for mass manufacture?
Not automatically. Production readiness can also involve testing, compliance, quality planning, tooling validation, supply-chain readiness and other product-specific work. We will distinguish those stages rather than treating DFM as a blanket sign-off.
