Aunov Tech builds this Aluminum Mascara Tube in stainless steel, from coil or bar through to the finished surfaces. In duty, the deep drawn tube guides or contains the mating part along its bore. Forming, machining and inspection share one floor, so the approved sample defines every later batch under one roof.
Product overview
The drawing for this aluminium tube fixes, the forming route, the tolerance band and the sealing faces, audited against the approved sample at each production release.
The whole route from die to finished aluminium tube stays in house, so a drawing change is absorbed in one step, and the approved sample is kept as the master.
Production route
Manufacturing runs on a controlled process path: Drawing converts a flat blank into the finished envelope in one controlled sequence; secondary machining holds the seats, threads and faces that forming cannot produce.
Each mascara tube shipment is verified against the master sample before it leaves the shop. The signed mascara tube sample remains the reference and is kept with the job file.
Materials and finishing
Standard stock includes carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this aluminium tube runs in aluminium.
The surface treatment is picked to match the service conditions: electrophoresis, powder coating, anodising and zinc / nickel plating. It is written into the drawing for this aluminium tube, so it cannot drift between batches.
Each mascara tube shipment is verified against the master sample before it leaves the shop. First article, drawing revision and material cert travel with each mascara tube batch.
Quality control
The factory operates with ISO 9001 certification: incoming material is verified against mill certificates, first-article geometry is confirmed on the CMM, and run inspections follow an agreed sampling plan. Wall thickness of the mascara tube is measured at first article. Tests for torque, leakage or pressure can be arranged when the service demands them, and the inspection report ships with each batch.
Where the part is used
The aluminium tube is specified into industrial and appliance assemblies under schedules that run for years at a time.
One drawing for this aluminium tube is commonly applied to several programmes, so one approved version covers the whole range, and approvals carry across programmes.
Specifications
| Item | Aluminum Mascara Tube |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – samples are reverse-measured into a controlled drawing; the same drawing is used for every repeat order. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Any sample deviation is corrected before the first production batch is released. |
| Materials | 1050 / 3003 / 5052 / 6061 aluminium, 0.5-3.0 mm stock – temper matched to the forming depth or machining route of this tube. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Coil blanking and progressive drawing, coining on the final station where the print calls for it; batch records are filed so a repeat order starts from approved data. |
| Equipment | Mechanical presses from 5 to 250 T and hydraulic presses 250-500 T, with in-line annealing furnaces; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T or L/C, quoted in USD or EUR; price breaks tie to annual volume. |
