Aunov Tech supplies the Wiper motor can as a stainless steel component manufactured entirely in house. In duty, the wiper motor housing carries the wiper motor internals and locates the output gear. Forming and machining share equipment, staff and batch records, so repeat orders stay aligned with the approved sample without handing the part to another vendor.
Product overview
What defines this metal can is, draw depth, wall band and the surfaces that forming cannot hold, all held to the drawing and verified at first article.
The whole route from die to finished metal can stays in house, so a drawing change is absorbed in one step, and the approved sample is kept as the master.
From coil to finished part
The process for this metal can runs in a fixed sequence: Drawing converts a flat blank into the finished envelope in one controlled sequence; wall thickness is checked at the thinnest section after forming.
The tooling record is stored against the part number, and a reorder is a repeat, not a new start.
Materials and finishing
Working stock covers SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal can is costed in carbon steel or stainless.
The finish is chosen for the environment the part sees: zinc and nickel plating, chrome, anodising, powder coating and passivation. The finish on this metal can is locked to the drawing revision, so later orders match.
Later runs are measured back to the first article, and grade changes have to be agreed in writing first.
Quality control
An ISO 9001 certified system governs production: stock arrivals are checked against mill certificates, the CMM measures the first article dimension by dimension, and run inspections follow an agreed sampling plan. At wiper motor housing level, output-shaft bore runout is checked on every first article, and seal seats are gauged for burr-free assembly. Functional testing – torque, leak or pressure – can be written into the plan, with certificates included in the shipment file.
Where the part is used
This metal can is used in automotive sub-assemblies and adjacent equipment across automotive, appliance and industrial programmes.
A single design of this metal can is often reused across a product family, so one tooling set serves every position, and the drawing stays common.
Specifications
| Item | Wiper motor can |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| Samples | First-article samples ship with a dimensional report and material certificate, so the part is proven before it is made in volume, and later batches are gauged back to the signed sample. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this can. |
| Surface finish | Zinc or nickel plating for corrosion, plus powder coating or electrophoresis on housings; laser etching on request. |
| Processing | Coil blanking, progressive drawing through 3-5 stages with anneals between, trim and pierce, then deburr and finish. |
| Equipment | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.1 mm on formed features and +/-0.2 mm on overall lengths; tighter bands confirmed against the die before quoting. |
| Delivery terms | CIF or DDP, with FOB available, payment by T/T or L/C, quoted in USD or EUR; sea or air freight is quoted to your door. |
