You're looking at silica sol investment casting with lost wax and full CNC finishing, so you get CT4-CT7 tolerances and Ra0.4 suface where it's machined—pretty much teh tightest we can deliver for instrumentation parts.
Materail options go from 201 up through 316L, alloy steel too, and our company can handle parts from 0.1kg to 80kg with wall thickness down to 2mm or even 1mm in micro-regions, which covers most OEM custom work.
We've got ISO 9001:2015 and RoHS, plus CMM and spectrometer for checking every batch—basically kind of inspection gear that keeps tolerances honest for critical use.
This isn't for heavy structural or high-impact stuff though; it's really about precision geometry where blind hole depth ratio is 1:1.5 and radii stay tight—external at least 0.3mm, internal 0.5mm.
Also, we work with Pro-E, Solidworks, UG, and a bunch of file formats like IGS, STP, or PDF, so you can just send over your 3D model without reformatting.
We usually start at 500 pieces for custom stainless steel parts, but it can vary depending on complexity and weight—just send your drawing and we'll quote.
Ra0.4 is only for machined surfaces; the as-cast finish runs Ra1.6 to Ra6.3. So if you need that mirror-like finish on a bore or face, we'll CNC it.
Yes, every batch comes with a material test report from our spectrometer, and we're ISO 9001:2015 and RoHS certified—happy to include those docs with your shipment.
We work with IGS, STP, XT, PDF, JPEG, and JPG—basically anything from Pro-E, UG, Solidworks, or AutoCAD. Just avoid raw sketches if possible.
Standard lead time is 25-35 working days after drawing approval and deposit. Rush orders can cut that down, but we'll need to confirm based on current shop load.
