Semiconductor charging equipment case
Insert Moulded Charging Station Enclosure
A second PC enclosure program for semiconductor charging equipment. The thin product and multiple insert moulded nuts required careful draft, local reinforcement and repeatable filling through trial correction.

01 · Customer need and engineering challenge
Engineering a thin enclosure with multiple insert moulded nuts
The customer required a 30 day mould delivery for a PC semiconductor charging station enclosure. The design combined thin sections with several insert moulded nuts, so the main review topics were filling, draft, local wall thickness and insert stability.
01
Thin product sectionsThin areas required a stable filling route and carefully controlled venting.
02
Multiple insert moulded nutsA larger number of inserts increased the risk of nut marks and incomplete filling around the interfaces.
03
Release and draftDraft was reviewed and increased where necessary to reduce release resistance.
02 · Tooling approach
Draft and insert detail refined through three trials
Five coordinated processes
CNC, slow wire EDM, mirror EDM, grinding and milling supported the mould build and detail finishing.
Three trial rounds
Short shots, nut marks and multiple insert issues were addressed by increasing draft and thickening the nut areas.
03 · Result and customer value
Stable moulded parts supported a smooth product launch
The mould was delivered within 30 days. Three trial rounds resolved the filling and insert related issues, reaching a final good part rate of 96%. The parts were accepted for assembly and the finished product moved into the market.
Customer business value
Reduced assembly risk around the insert interfaces and supported the customer's planned product launch.
