Drawing Review
Engineers review customer drawings for dimensions, tolerances, material specs, and surface finish requirements to ensure clarity and feasibility.
Process Analysis
· Assess part geometry and complexity for suitable machining processes.
· Identify needs for special fixtures/tools and potential challenges (e.g., deep holes, thin walls).
Material Inspection
· Verify material availability and suitability.
· Consider machinability, cost, and lead time.
Feasibility Suggestions
· Provide a feasibility report with evaluations and recommendations.
· Communicate issues and propose design modifications if needed.
Cost Evaluation
Estimate costs based on processes, materials, and time.
· Identify cost-saving opportunities through design improvements.
- 03 Order Confirmtion & Production
Sample Processing
Conduct sample processing according to the process plan.
Sample Quality Inspection
Verify the machining results through measurements and tests.
Buyer Sample Confirmation
Send photos and videos of the sample to the customer for initial confirmation, then ship the physical sample to the customer for inspection and approval.
Physical Sample Confirmation
Upon receiving the physical sample, the customer can request modifications if needed. The designer will make adjustments based on the customer’s feedback.
Mass Production Planning
Once the sample receives final approval from the customer, Xielifeng finalizes the batch production plan, including production schedule, material procurement, and equipment allocation.
- 04 Quality Inspection & Delivery
Raw Material Inspection
Before production, raw materials are strictly inspected for composition, properties, and quality to meet specifications.
First Part Inspection
Before mass production, one or several parts are produced for first article inspection to ensure the correctness of the production process and equipment settings.
In-Process Inspection
During production, random sampling inspections are conducted at regular intervals to ensure product quality throughout the production process.
Final Inspection
After production, each batch undergoes a final inspection to ensure it meets customer requirements.
