Boca Raton, FL 33431, United States, 16th Oct 2026 – Yijin Solution, a trusted precision manufacturing company of CNC machining, has announced how it carries custom parts from prototype through to volume production. The announcement describes a process in which the results of prototype and validation work carry directly into production setup, so a project does not have to restart when it moves to the next stage.
The company provides custom parts manufacturing across CNC machining, sheet metal fabrication, injection molding, die casting, 3D printing, assembly and finishing. Its customers include those in consumer electronics, medical devices, automotive and industrial applications. The company said handling these processes together keeps drawings, materials and inspection requirements aligned as a project scales.
Why the Handover Matters
Moving from prototype to production can be the point at which custom part projects slow down. Prototypes are commonly made by CNC machining or 3D printing, while production may rely on injection molding, die casting or sheet metal fabrication, each with its own tooling, tolerances and lead times. A part that performs well as a prototype can therefore need design changes before it can be made repeatably in volume.
Changes of that kind are generally easier to make before production tooling is cut than after, which is why design reviews tend to happen early. Yijin Solution offers free design for manufacturability reviews for CNC machining, sheet metal fabrication and 3D printing. Reviews of this kind typically look at wall thickness, tolerances and material choice, so that risks can be flagged before production begins.
How the Process Works
According to the company, production follows four steps. The first reviews production needs, including quantity targets, quality requirements, delivery schedule and open validation issues. The second sets up processes, materials, tooling, assembly sequences, finishing and the supply chain. The third manages manufacturing, inspection, assembly, finishing and shipment against plan, and the fourth continues work on cost, quality, yield and delivery after production starts.
The company said projects often begin with pilot batches and scale to volume once production stability is confirmed.
“A project that starts as a prototype rarely ends there, and each handover between suppliers adds time and risk,” said Gavin Yi, CEO of Yijin Solution. “Keeping validation, tooling and production in one process means the drawings, materials and inspection requirements move forward together.”
Tooling, Lead Times and Quality
Tooling is part of the same timeline. For injection-molded and die-cast products, the company said mold design, mold manufacturing, trial shots and process validation are handled in-house. Mechanical assembly, sub-assembly, custom packaging, kitting and delivery preparation are also listed as in-house services, and finishing options include anodizing, plating, powder coating, PVD and polishing.
Yijin Solution said published lead times vary by process. Prototypes made by CNC machining, sheet metal fabrication or 3D printing are listed at 3 to 7 days. Injection molding tooling is listed at 15 to 45 days, with first samples 3 to 7 days afterward and production runs taking 2 to 4 weeks. For CNC work, the company said it operates 136 or more machining centers and 278 lathes.
The company lists ISO 9001, ISO 13485 and IATF 16949 among its quality certifications, and AS9100D for CNC and sheet metal work. Customers requesting a quote upload 2D drawings and at least one 3D CAD file, and up to 15 files can be submitted in formats including STEP, IGES, DWG, PDF and STL.
Looking Ahead
Yijin Solution expects each project to be reviewed against its own quantity, quality and delivery targets, both before and after production starts.
“The practical test is whether a part made in volume matches the approved prototype,” said Gavin Yi, CEO of Yijin Solution. “Production will continue to be reviewed against those targets, and work on cost, yield and delivery will carry on after production begins.”
