Starting with a 50-piece qualification order
Blue Robotics asked Shenghao to produce a sample batch of WLC ILP press-fit components in 7075-T6 aluminum. The drawing called for black hard anodizing, green screen printing and ±0.02 mm dimensional tolerance after finishing.
The first order covered 50 parts. This gave the customer a practical batch for inspection before deciding how to proceed with later part numbers and larger volumes.
Changing the groove process before production
The original groove method could leave pressure marks on the adjacent flat surface. Shenghao raised the issue during review and proposed CNC machining the groove instead.
The machined groove kept a slightly rounded form where the requested geometry could not be reproduced exactly. That tradeoff was shared with the customer before finishing, so the visible result was understood before the parts moved forward.
Inspecting the parts after anodizing
The parts were hard anodized black and screen printed. Shenghao supplied dimensional, material and surface-finish documentation with the order.
After delivery, the batch went through the customer's own inspection. Shenghao supplied dimensional, material and surface-finish documentation with the order; this account does not report the customer's inspection measurements. Two further part numbers were later sent to Shenghao for prototype quoting.
What this project shows
Post-finish tolerance should be planned before machining starts. Anodizing adds material, visual features affect the process route, and a groove that looks simple in CAD can require a different manufacturing method to protect the surrounding surface.
This case covers the completed 50-piece sample batch. Later volume forecasts and follow-on part requests were still under evaluation.
