Capability

Contract Manufacturing

Precision machining, metal fabrication, stamping and assembly through a qualified partner network — build-to-print or build-to-spec, prototype through production volume, with the inspection and documentation package your program requires.

Build-to-print & build-to-spec

Prototype → production

PPAP / FAI capable

Processes

What the network makes

We match the part to the shop that runs that process every day — not to whichever supplier happens to be free.

Precision machining

CNC milling and turning of steel, stainless, aluminum and engineered plastics; multi-axis and production-cell work.

Metal fabrication

Laser and plasma cutting, forming, welding and finishing of sheet and plate assemblies.

Stamping

Progressive and secondary stamping for high-quantity parts, including tooling design and management.

Assembly

Mechanical and electromechanical sub-assembly, kitting, and packaged deliverables ready for your line.

Engagement models

Two ways to bring us a part

Build to print

You own the design. We review the drawing for manufacturability, flag tolerances that drive cost, quote against your revision level, and produce to print with first article approval before production release.

Build to spec

You define function, envelope and duty cycle. Our engineers develop the design, material selection and process plan, then carry it through prototype and qualification into production.

Prototype through production

Prototype quantities are run on the process that will make the production part wherever possible, so qualification data stays valid when volume ramps.

Capability

What we can make, and how we decide

A capability list tells you what a shop owns. It doesn't tell you whether your part is a good fit for it. We qualify that question before we quote, across a partner network covering machining, fabrication, stamping, finishing and assembly.

Machined and turned parts

Milled and turned components in aluminum, steel, stainless and engineered plastics, from prototype quantities through recurring production runs. Multi-axis work where the part geometry requires it, and simpler setups where it doesn't — the process is chosen against the drawing, not against what a shop happens to have free.

Tolerance capability is confirmed per part rather than claimed in general. Before we quote, we identify which features are critical, which partner holds the process capability to hold them, and what inspection method proves it. If a tolerance on the print is tighter than the process can reliably hold, you hear that during the quote, not after first article.

Fabrication, stamping and forming

Sheet metal fabrication and weldments for enclosures, brackets, frames and structural assemblies. Progressive die stamping where volume justifies tooling, and press brake or laser-cut fabrication where it doesn't — including the analysis of where that crossover actually sits for your annual quantity.

Welded assemblies are qualified on the joint, not the shop. We confirm the weld process, the operator qualification behind it, and the inspection standard the joint will be accepted against, before the first assembly is built.

Finishing and assembly

Plating, painting, powder coating, anodizing and passivation through qualified finishing sources, specified to the standard your program calls out rather than to a shop's house process. Mechanical assembly and kitting, including sub-assemblies delivered ready to install on your line.

Where a part moves through multiple processes and multiple suppliers, BCI remains the single supplier of record. One purchase order, one point of accountability, and one party responsible when a dimension at final inspection traces back to an operation three steps upstream.

Send a drawing and a volume. We'll tell you which process fits, which partner runs it, and what it costs landed.

Questions we get asked

Contract manufacturing — common questions

Answers for engineering and procurement teams evaluating a manufacturing partner.

What is contract manufacturing?

Contract manufacturing is having a third party produce your parts or assemblies to your design. BCI places the work with a qualified manufacturing partner, manages the engineering review and inspection, and remains the supplier of record on your purchase order.

What is the difference between build-to-print and build-to-spec?

Build-to-print means you own the design and we manufacture to your drawing and revision level. Build-to-spec means you define function, envelope and duty cycle, and our engineers develop the design, material selection and process plan before production.

Do you provide PPAP and first article inspection?

Yes. We provide first article inspection reports and PPAP submissions at the level you specify, including control plan, process flow, PFMEA, capability studies and measurement system analysis.

How do you handle engineering changes?

Drawing revisions are re-quoted and re-qualified as required, and we notify you in advance of any process, tooling or sub-tier change on our side.

What manufacturing processes can BCI provide?

Precision CNC machining and turning, sheet metal and plate fabrication, welding, progressive and secondary stamping, finishing, and mechanical and electromechanical assembly — through a partner network qualified per process.

Can you make prototypes as well as production parts?

Yes. Wherever possible prototypes are run on the same process that will make the production part, so qualification data stays valid when volume increases.

Who are your manufacturing partners?

Our partner network includes Cenflex Precision Manufacturing, Starflex Fabrication, Cadrex Manufacturing Solutions, KDM Metal Machinery, Titan Metal Fabricators, Thyssenkrupp and Ranflex Metals. We disclose which partner is assigned to your part during vendor qualification, under NDA.

Will you review my drawing for manufacturability?

Yes, before quoting. We flag tolerances, finishes and material callouts that add cost without adding function, and propose alternatives for you to approve or reject.
