What We Offer

Free DFM Review

Send your 3D CAD model or 2D drawing and our engineers review it against the manufacturing process you have in mind. We flag features that will be hard to machine, hold tolerance on, or finish consistently, then explain the geometry risks, tolerance feasibility, material fit, and surface finish achievability. The review is grounded in what runs on our shop floor every day across 136+ CNC machining centers, 80+ Swiss-type lathes, press brakes, and stamping lines.

Unser Leitfaden für die Gestaltung: Wie man Geld spart

Free Part Design Modification

If your part has features that will not produce well as drawn, we suggest specific modifications. That can mean opening a tight internal radius, adjusting a draft angle, relaxing a tolerance that is not load-bearing, or recommending a different finish that meets the same functional requirement at lower cost. We work from your existing design rather than starting over, so your intent stays intact and only the features that block production get adjusted.

Engineering Design Support You Can Trust

Our in-house engineering team reviews drawings the same way they program jobs for production, with hands-on knowledge of how each material behaves under each process. We hold AS9100D for aerospace, IATF 16949 for automotive, ISO 13485 for medical, and ISO 9001 and ISO 14001 for general manufacturing and environmental management. The same engineers who give you DFM feedback can take the part through prototyping, low-volume production, and full serial production once the design is locked.

What We Need From You

  • vector 3D CAD files or 2D drawings
  • vector Existing part design or technical drawings
  • vector Target quantity / prototype or production stage
  • vector Material or application requirements if available
  • vector Any known manufacturing concerns

Our Review Process

Send your file across, get engineering feedback within 24 to 48 hours, then move directly into quotation or production with the revised design.

Submit Your Drawing

Upload your 3D CAD file (STEP, IGES, X_T, or native) or a dimensioned 2D drawing (PDF or DWG). Tell us the target process, quantity, material, and any critical features.

Production icon

Technische Überprüfung

Our manufacturing engineers walk through the design feature by feature and check it against the realities of CNC machining, sheet metal forming, casting, or stamping, depending on the process you specified.

Quality control icon

Optimization Feedback

You receive a written report covering geometry risks, tolerance concerns, material recommendations, and finishing options. Where changes are needed we give specific suggestions, not vague flags.

Delivery icon

Move to Quotation or Production

Once you accept the feedback and revise the design, or decide to keep it as drawn, we generate a formal quote. Approved orders move into prototyping in 3 to 7 days, with full production in 2 to 4 weeks.

Why Choose Yijin Solution for Sheet Metal Stamping

The DFM review you receive comes from the engineers who run our production floor. Their feedback is grounded in what actually runs through our presses, mills, and lathes, not in textbook design rules. That production-level knowledge is the difference between feedback that catches the real problems and feedback that catches the obvious ones.

precision and quality
Production-Based Feedback

Every recommendation comes from engineers who run the same process daily. We have seen which features fail on the press and which tolerances actually hold on the mill, so the feedback you receive is what works on our floor, not what looks good on paper.

fast turnaround
In-House Engineering Team

DFM reviews are handled by the same engineers who program your job for production. There is no handoff between the team that reviews your drawing and the team that builds the part, which keeps the feedback grounded and the quote accurate.

order any size
Diverse Manufacturing Processes

We run CNC milling and turning, Swiss-type lathes, press brakes, sheet metal stamping, die casting, injection molding, and 3D printing in-house. That breadth means we can recommend the right process for your part rather than forcing it onto whatever line we happen to have.

prototyping to production
Prototyping to Production

Approved designs flow straight into manufacturing. Prototypes ship in 3 to 7 days and full production runs in 2 to 4 weeks, with the same engineering team carrying the part through every stage.
