Aunov Tech manufactures the Experienced Deep Drawing Brass Copper Stainless Steel Aluminum Deep in brass or copper on a single production floor. On the product, the CNC machined part provides the finished surfaces, threads and seats the mating parts locate on. Forming, machining and inspection share one floor, so repeat orders stay aligned with the approved sample under one roof.

Product overview

What defines this stainless steel component is, the draw ratio, corner radii and the faces that must stay flat, recorded on the inspection report for every batch.

Toolroom, presses and machining centres used on this stainless steel component operate on the same site, which keeps revision loops short and samples fast, and the approved sample is kept as the master.

How it is manufactured

Production of this stainless steel component is locked to one route: Drawing converts a flat blank into the finished envelope in one controlled sequence; after drawing, critical faces are machined and the part is degreased and gauged.

Batch records for the sleeve are filed against the part number, so process settings are reused instead of re-invented. That record is what every sleeve reorder is built on, so nothing changes silently between shipments.

Materials and finishing

Working stock covers SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel component is costed in 304 / 316 stainless steel.

The finish is chosen for the duty it will see: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this stainless steel component, so the decision never has to be made twice.

Batch records for the sleeve are filed against the part number, so process settings are reused instead of re-invented. Deviations on the sleeve are reported before shipment rather than found on your assembly line.

Quality control

Quality management is certified to ISO 9001: material traceability starts with mill certificates, first-article geometry is confirmed on the CMM, and routine sampling keeps batches aligned with the first article. The sleeve first article goes on the CMM, with threads gauged to class. Functional testing – torque, leak or pressure – can be written into the plan, and the report is packed with the shipment.

Where the part is used

You will find this stainless steel component inside industrial and appliance assemblies for customers who buy to drawing.

The same stainless steel component is used across several platforms, so one approved version covers the whole range, and the die does not have to change.

Customization and options

Frequently varied options in this sleeve family

Typical decisions customers make on this stainless steel component: material grade, coating, wall bands, flange form and end closure, and whether the first order is a prototype, a pilot lot or a production release.

Tooled and untooled options for this stainless steel component are listed separately, so the cost of a change is visible before you commit. Price validity for the sleeve is stated on the quotation and respected.

DesigningMade to your 2D/3D drawings (PDF, DWG, STEP, IGS) – a manufacturability review comes back with the quotation; the agreed version governs every later batch.
ToolingOur toolroom covers die design, wire-cut EDM and maintenance, so no tooling step is outsourced, and maintenance is tracked against the part number.
SamplesFree samples are available on standard items, with reports attached.
MaterialsStandard stock: carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass; grade and temper are confirmed in writing before tooling.
Surface finishNatural, plated or coated – the print decides, and the agreed finish is logged; alternatives quoted with the quotation, samples approved in writing.
ProcessingDeep drawing on maintained presses, blank size and lubrication logged per run; batch records are filed so a repeat order starts from approved data.
Equipment5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line; secondary ops run on CNC turning centres, inspection on the CMM.
Tolerance+/-0.1 mm general on drawn sections, +/-0.03 mm on machined seats; finer bands confirmed from capability data before quoting.
Delivery termsFOB, CIF or DDP per Incoterms 2020, T/T with deposit and L/C for larger runs; call-off schedules are supported.

Packaging and delivery

Packing for this stainless steel component is chosen around the coating: each coating gets its own packing – interleaves, bags or trays, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
