Aunov Tech supplies the Wiper Motor Cap with Shaft Boss as a stainless steel component manufactured entirely in house. In the assembly, the wiper motor housing drives the link and blade assembly through a geared output shaft. One production floor covers forming, finishing and inspection, so the approved sample defines every later batch without re-quoting the job elsewhere.
Product overview
What defines this metal cap is, wall thickness control, flange geometry and the sealing surface, all held to the drawing and verified at first article.
The whole route from die to finished metal cap stays in house, so a drawing change is absorbed in one step, and nothing about the route depends on a third party.
How it is manufactured
This is how the metal cap is built: Blanks are drawn in stages, with interstage annealing where the wall thins; threads are single-pointed or rolled and seats bored in one setup where possible.
Batch records are filed against the part number, so nothing depends on the operator remembering.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal cap runs in carbon steel or stainless.
The coating is matched to the working environment: electrophoresis, powder coating, anodising and zinc / nickel plating. It is fixed on the drawing for this metal cap, so repeat orders never reopen the question.
Later runs are measured back to the first article, and grade changes have to be agreed in writing first.
Quality control
Production runs under an ISO 9001 certified quality system: incoming material is verified against mill certificates, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. On the wiper motor housing itself, output-shaft bore runout is checked on every first article, and seal seats are gauged for burr-free assembly. Tests for torque, leakage or pressure can be arranged when the service demands them, and the report is packed with the shipment.
Applications
This metal cap normally works inside automotive sub-assemblies and adjacent equipment for customers who own the drawing and the tooling.
One drawing for this metal cap is commonly applied to several programmes, so a single grade and coating can cover each application, and no re-tooling is needed.
Specifications
| Item | Wiper Motor Cap with Shaft Boss |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – unusual walls, threads or tolerances are feasibility-checked first; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so tooling lead time stays under our control, and the charge is refundable against agreed volumes. |
| Samples | Pre-production samples come with a full inspection report, so the sample is retained as the master, and the signed sample is kept for future reorders. |
| Materials | Stock covers carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| 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 | +/-0.05 mm to +/-0.1 mm across the part; tighter bands confirmed against the die before the quotation is fixed. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; sea or air freight is quoted to your door. |
