Design Optimization Before Prototyping

Before manufacturing begins, our engineers review your design, materials, tolerances, assembly requirements, and intended application. Early optimization helps reduce prototype revisions, control costs, and improve the transition toward production.

DFM Review

We review part geometry, wall thickness, tolerances, undercuts, tool access, and manufacturing risks before prototype production begins.

CAD & Engineering Optimization

Our team refines CAD models, part structures, assembly interfaces, and manufacturing details according to the selected production process.

Prototype Validation Planning

We define the materials, processes, critical dimensions, finishing requirements, and testing priorities needed for meaningful prototype validation.

Prototype Testing & Engineering Validation

A functional prototype must be evaluated against its intended application—not only its CAD model. Yanmee supports dimensional, assembly, material, surface, and functional checks to help identify design risks before tooling or production begins.

Dimensional Inspection: Verify critical dimensions, tolerances, hole positions, and mating features against approved drawings.
Fit and Assembly Testing: Confirm that components align, fasteners engage correctly, and assembled parts operate as intended.
Material Evaluation: Assess strength, flexibility, heat resistance, surface behavior, and other application-related properties.
Functional Validation: Test movement, interfaces, ergonomics, mechanical performance, and real-use conditions where applicable.

From Validated Prototype to Low-Volume Production

After the design and prototype have been validated, Yanmee helps prepare the project for pilot builds and repeatable low-volume manufacturing. Production requirements are reviewed to improve process stability, part consistency, inspection efficiency, and future scalability.

Pilot Production: Produce initial batches to verify tooling, fixtures, process settings, assembly steps, and inspection requirements.
Process Optimization: Refine manufacturing methods to improve consistency, lead time, material use, and production efficiency.
Quality Planning: Define critical dimensions, appearance standards, inspection methods, and acceptance requirements.
Assembly Verification: Confirm that parts, finishes, hardware, and electronic components integrate correctly.

Testing and Evaluation

Prototype Testing and Validation

Evaluate critical dimensions, assembly fit, functional performance, material behavior, and design improvements before moving toward tooling or low-volume production.

Dimensional Inspection

Critical dimensions, tolerances, hole positions, wall thicknesses, and mating features are checked against approved drawings. Suitable measuring equipment is selected according to the part geometry and project requirements.

Fit & Functional Testing

Prototype components are assembled to evaluate alignment, fastening, movement, interfaces, and overall operation. Testing helps identify interference, assembly difficulties, and functional risks before production preparation.

Material & Durability Evaluation

Materials and finished parts can be evaluated for strength, flexibility, temperature exposure, surface behavior, and application-related durability. Testing requirements are defined according to the product’s intended use.

Clear Cost and Lead Time Evaluation

Yanmee evaluates each project according to its design, material, process, quantity, tolerance, surface finish, inspection, and delivery requirements. Our engineering team reviews these factors before providing a practical quotation and estimated production schedule.

Early project evaluation helps identify unnecessary costs, select suitable manufacturing methods, and reduce delays caused by unclear specifications or design changes.

For Faster Evaluation: Please provide your 3D CAD file, 2D drawing, material, quantity, surface finish, critical tolerances, and expected delivery date.

Tolerance Management for Functional Prototypes

Correct tolerance planning ensures that prototype components fit, assemble, and perform as intended. Yanmee reviews critical dimensions according to part geometry, material, manufacturing process, assembly relationships, and application requirements.

Rather than applying unnecessarily tight tolerances to every feature, we focus precision where it matters most. This helps balance functional performance, manufacturability, inspection efficiency, lead time, and cost.

Tight Tolerances	Achieving tolerances as tight as ±0.05 mm, ensuring high precision in complex parts.
Cost Control	Optimizing tolerance levels to balance quality and cost efficiency for prototypes and production parts.
Consistency	Maintaining consistent quality across all parts through rigorous inspection and validation.
Material Adaptability	Tolerance management adapts to various materials to ensure optimal results regardless of the material used.

Our engineering team can help optimize your design.
