Fin die
Tianjin Keletri Machinery And Electric Equipment Co., Ltd. supplies precision fin dies for metal forming in heat exchanger and radiator manufacturing. The die consists of integrated sub-dies for piercing, extruding louvers, trimming edges, and longitudinal cutting, all mounted on a P20 pre-hardened die plate. The tooling is built for high-volume stamping, with guideposts and ball retainers ensuring alignment under repeated cycles.
The piercing and louver punches are made from Assab tool steel, hardened and ground to tight tolerances. The die plate uses P20 steel at 28-32 HRC, while sub-dies are made from CrWMn high-carbon steel, heat-treated and CNC ground. Side slitters and cut-off blades are fabricated from Assab 88, known for wear resistance in high-impact applications. The die life is rated at over 100 million cycles under normal 8-hour daily operation, excluding consumable parts.
These dies are used by manufacturers of aluminum and copper finned tubes in HVAC, automotive, and industrial heat exchangers. Buyers typically order custom configurations based on fin height, pitch, and material thickness. Packaging is in steel cases with internal foam padding. MOQ is one die set, with lead times of 8 to 12 weeks. Spare parts such as springs, punches, and blades are sold separately and must be ordered as needed.

Sourcing Fin die from Tianjin Keletri Machinery And Electric Equipment Co., Ltd. - China Import Guide
Before ordering, verify the die’s material certifications for all tool steels, especially Assab and CrWMn grades. Request hardness test reports and dimensional drawings with tolerances. Confirm the die’s compatibility with your press tonnage and stroke length. Do not assume standard dimensions - each die is custom-built. Ensure the supplier provides assembly diagrams and maintenance instructions in English.
Confirm Incoterms, shipping method, and lead time before payment. Dies are shipped in steel cases with internal foam, typically FOB Tianjin Port. Lead time is 8 to 12 weeks. Payment is usually 50% advance, 50% before shipment. Ask for a packing list with part numbers and serial markings. Verify the container is sealed and labeled for customs clearance.
Upon arrival, inspect for shipping damage and compare components against the packing list. Perform a dry run on your press without material to check alignment and stroke sync. Test with a sample of your material to validate fin formation, edge quality, and burr control. Retain all documentation, including material test reports and assembly instructions, for quality audits and future maintenance.
