It’s a custom cold chamber die casting job in ADC12 aluminum alloy, with a horizontal presure chamber structure that’s pretty much standdard for these high-volume battery heat sink runs, and the tolerance grade is 5 with a casting surface qualiy level of 2 so you’re not chasing after burrs.
2, we offer PDF, DXF, DWG, STEP, IGS, X-T for the drawing format and free DFM on the mold design—send us your file and we’ll run the simulation—then it goes through polishing and CNC machining before the powder coating or paint surface treatment is applied depending on what the end use needs, and the MOQ is small so you can order 50 units or so for a pilot.
2 years on the warranty and the full inspection before shiping covers dimensional checks with a CMM and a salt spray test for teh coating, but we also have an airtightness tester if you’re using it in a battery case where sealing matters; it’s better than bare extrusion for this because the die cast fins have a tighter tolerance than most extruded profiles.
Actually, this isn’t suited for liquid-cooled plates or anything requiring high thermal conductivity above 200 W/mK because ADC12 is around 96 W/mK give or take, though for passive dissipation in battery packs it works fine, and we usually keep stock on the molds once they’re cut but confirm lead time on first run.
10 production lines running in-house, so we can handle the die casting, drilling, and any secondary machining you specify, and the transport package is whatever you put on the spec sheet—corrugated boxes or wooden crates depending on quantity, and we’ve got CE, RoHS, ISO 9001:2015, and IATF16949 on file.
We keep a small MOQ, so you don’t have to place a huge order to get started. Just share your design, and we’ll work with you even for small batch runs.
We hold ISO9001:2015, IATF16949, CE, and RoHS certifications, so you’re covered for quality and compliance. Full inspection is done before shipping.
We accept PDF, DXF, DWG, STEP, IGS, X-T, and more. Just send your file, and we’ll provide a free DFM to confirm the design before production.
We offer fast delivery, usually within 2-4 weeks depending on quantity and complexity. We’ll confirm the exact timeline after reviewing your specs.
We can do paint, powder spraying, electroplating, and more. For battery applications, powder coating is common, but we’ll match your needs.
