Send the Drawing or Technical Requirements

Every project begins with technical information. Customers may provide a 2D drawing, 3D model, physical sample or detailed specification.

Important information includes material, dimensions, tolerances, surface requirements, quantity and application.

Drawing Review

Before production, the drawing should be reviewed from a manufacturing perspective.

Engineers may check whether dimensions are clearly defined, tolerances are realistic and manufacturing notes are complete.

The objective is not to change the customer's design without approval, but to make sure all requirements are clearly understood.

Engineering Evaluation

Once the design is understood, the manufacturing process can be evaluated.

This includes equipment selection, machining sequence, fixture requirements and secondary operations.

One component may be suitable for CNC milling, while another may require turning, Swiss machining, grinding or several combined processes.

DFM Review

Design for Manufacturability can help identify unnecessary manufacturing difficulty before prototype production.

Examples include unnecessarily tight tolerances, deep narrow cavities, difficult internal corners or features requiring multiple setups.

Manufacturing feedback can help improve production efficiency while maintaining the required function.

Prototype Development

Prototype production allows the design to be evaluated using actual manufactured parts.

Customers can verify dimensions, assembly fit, appearance and functional performance.

Prototype quantities are normally small because the objective is validation rather than volume production.

Inspection and Sample Approval

After prototype production, critical dimensions and specified requirements should be inspected.

The customer may also perform assembly or application testing.

If the sample meets expectations, the project can proceed toward production approval. If changes are required, the drawing or process can be updated first.

Production Planning

Mass production requires more than simply repeating the prototype process.

Manufacturing methods may need to be optimized for cycle time, repeatability and quality control.

Fixtures, tooling, machine allocation and inspection frequency can all be reviewed before volume production begins.

Mass Production

Once the process is confirmed, production can begin according to approved requirements.

Raw material control, machine setup, tooling condition and in-process inspection all contribute to consistent production.

Final Inspection

Finished components should be checked against the agreed technical requirements before shipment.

Inspection may include dimensions, appearance, threads, surface treatment and other customer-specified characteristics.

Packaging and Delivery

Precision components can still be damaged after production if packaging is not appropriate.

Finished parts may require individual protection, trays, bags, customized cartons or other packaging depending on surface sensitivity and transport conditions.
