Gst Precision Tool, based in Wuxi, Jiangsu, China, manufactures a fin die designed for high‑volume extrusion of finned tubes and heat‑exchanger components. The die is machined from tool steel / high‑speed steel (HSS) and offered in grades D2 or M2, providing the hardness required for shaping copper, aluminium or brass fins. Its construction tolerates the pressures of industrial forming while maintaining dimensional accuracy across long production runs. The supplier lists payment options such as L/C or T/T for bulk orders.
Tool steel D2 and M2 are standard grades that achieve a typical hardness of 60‑62 HRC after heat treatment, a level commonly required for repeatable fin geometry. Typical dimensional tolerance for precision dies of this class is ±0.02 mm, and a surface finish of Ra 0.8 µm is usually targeted to minimise friction during extrusion. Cryogenic treatment is a typical post‑process that enhances wear resistance and extends tool life. These industry norms ensure the die can operate continuously in HVAC, refrigeration or automotive radiator production lines.
Manufacturers of HVAC systems, commercial refrigeration units and automotive radiators commonly integrate this die into their assembly lines to achieve consistent wall thickness and fin spacing. Buyers seeking reliable tooling should confirm the exact grade, hardness and tolerance required for their specific material, and request a sample run to validate performance. Trade terms are negotiable, with the supplier indicating acceptance of L/C or T/T and offering packaging suitable for container shipment, though exact packaging details should be verified directly.

Before placing an order, verify the steel grade (D2 or M2) and request the hardness and dimensional tolerance certificates to ensure the die meets your production tolerances. Ask the supplier to confirm whether the die has undergone the typical cryogenic heat‑treatment and to provide a surface‑finish report. Because the listing does not state any certifications, request a copy of the ISO 9001 audit or any other relevant test reports to validate quality management.
Clarify the agreed Incoterm, as the supplier mentions acceptance of L/C or T/T but does not specify shipping terms; common choices are FOB Wuxi or CIF a Chinese port. Request an estimated lead time for tooling manufacture and any required tooling drawings, and confirm whether the die will be shipped in a standard wooden crate or if alternative packaging is needed for oversized orders. Payment schedules should be aligned with the agreed credit terms.
Arrange for a third‑party inspection at the factory before dispatch to verify material grade, hardness, and surface finish against the supplied certificates. Request a full inspection report and a mill test report (MTR) accompanying the shipment. Ensure that the supplier prepares a packing list, commercial invoice and, if required by your market, a certificate of origin to facilitate customs clearance.
