For fin die projects, the first email should be technical enough to let the engineering team understand the fin geometry and production target. A vague request like “please quote fin die” usually creates several rounds of clarification.
Core fin data
- Fin material: aluminum, copper, stainless steel or special alloy.
- Material thickness and target fin size.
- Fin pitch, tube diameter, tube pattern and number of rows.
- Hole shape, collar height, louver or slit requirement.
Production information
- Target strokes per minute or required production capacity.
- Existing press model, tonnage and feeding direction if available.
- Sample fin photos, heat exchanger application and drawing files.
How Sinoak reviews a fin die request
After receiving the basic data, Sinoak can review the forming requirement, punching layout, press matching and production target before confirming the recommended tooling scope.
