Почему стоит выбрать Yijin Solution
In-House Manufacturing Capabilities
Every process runs under our own roof — CNC machining, Swiss turning, sheet metal, die casting, injection molding, and finishing. No brokered work, no hidden subcontractors. That means tighter control over quality, faster scheduling decisions, and lead times we can actually commit to.
ISO-Certified Quality System
Our facility operates under AS9100D (aerospace), IATF 16949 (automotive), ISO 13485 (medical devices), ISO 9001, and ISO 14001. Every batch moves through a documented quality management system with full traceability — from material certificate to final inspection report.
Free DFM & Engineering Review
Upload your design and our engineers review it before you pay for a single part. We flag manufacturability issues, suggest tolerance and material adjustments, and estimate per-part cost at volume — so problems get solved on screen, not discovered after tooling.
Comprehensive Engineering Support
One engineering team takes your project from first drawing to final shipment. You will have direct access to the engineers running your job, with coordinated handoffs across machining, finishing, inspection, and logistics. You manage one relationship, not five vendors.
