CF8 Stainless Steel Quick-Connect Coupling Body
YTD produced this coupling body using silica-sol investment casting, with tooling adapted to its quick-connect features and finish machining of the cylindrical inner bore.
Material
CF8 stainless steel
Application
Quick-connect coupling
Manufacturing
Silica-sol investment casting
Supply scope
Casting and internal bore machining
Tooling adapted to the connection design.
A sliding section in the wax-pattern die allowed the overhanging connection features to be formed and released.

Customer Requirements & YTD’s Approach
Customer requirement
YTD’s approach
Customer requirement
Produce the specified connection geometry
The raised features overlap the groove below, making wax-pattern release more difficult.
YTD’s approach
Adapt the wax-pattern tooling
An additional sliding section addressed the release difficulty at the connection end.
Customer requirement
Supply the body with its inner bore finished
The project required machining of the cylindrical interior after casting
YTD’s approach
Complete casting and bore machining
YTD supplied the CF8 body with the specified internal machining completed.
A Small Tooling Change That Made the Shape Possible
The main manufacturing challenge was at the quick-connect interface. Part of the raised structure sits over a recessed groove, preventing a simple straight release from the wax-pattern die.
YTD incorporated a sliding section into the tooling. This section moves out of the way before the wax pattern is removed, allowing the connection geometry to be reproduced.
For the customer, the solution addressed the manufacturing difficulty while retaining the required part shape.
