This Stamped Steel Shallow Drawn Motor Cover is a shallow-drawn steel cover with a domed centre and locating bosses, trimmed and pierced in a compound die. Aunov Tech quotes and builds it to customer print, with die design, pressing, finishing and inspection on one floor – so a drawing change is re-sampled in one place instead of being handed to another vendor.
Product overview
For this shallow drawn motor cover, the drawing centres on the pierced pattern and formed flanges, recorded on the inspection report that ships with every batch.
Die work, pressing and finishing sit on the same floor, so a drawing change is absorbed in one step, and the approved sample is kept as the master.
From coil to finished part
Manufacturing runs on a controlled path: coil is blanked and drawn in a progressive die, with in-die sensing watching critical features on every stroke.
The shallow motor cover manufacturing record is archived together with the drawing revision that produced it. The signed shallow motor cover sample remains the reference and is kept with the job file.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, HSLA and galvanized sheet, 304 / 316 stainless, aluminium and copper, and the material for this shallow drawn motor cover is confirmed in writing before tooling.
The coating is matched to the service conditions: clear zinc or natural, with zinc, nickel or chrome plating, powder coat, e-coat and passivation available, Once approved, the finish is locked and does not drift between batches.
Quality control
The shallow motor cover first article goes on the CMM, with threads gauged to class. For this shallow drawn motor cover the critical features are 100% gauged, and torque, salt-spray or leakage tests are arranged where the service demands them, with certificates included in the shipment file.
Typical applications
Typical installation is in automotive, appliance and industrial equipment assemblies for OEM and Tier-1 customers who buy to drawing.
Customization and options
What customers usually vary:: material, coating, hole sizes, formed features and how the order is released, with orders run as prototypes, pilot lots or scheduled call-offs.
The shallow motor cover is small in the bill of materials and large in the warranty claim when it goes wrong. The shallow motor cover tolerances that matter are confirmed with capability data before pricing is agreed.
Specifications

| Samples | Pre-production samples come with a full inspection report, so the shallow drawn motor cover is proven before volume production, Later batches are gauged back to the signed sample. |
| Materials | SPCC cold-rolled steel, 1.2 mm; mill certificate and heat-number traceability supplied with the first article. |
| Surface finish | clear zinc or natural; alternatives quoted against the drawing. |
| Processing | shallow draw + trim – a shallow-drawn steel cover with a domed centre and locating bosses. |
| Equipment | Press shop with 5-250 T mechanical presses and dedicated dies, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | ±0.08 mm dome height; ±0.10 mm hole pattern; critical dimensions 100% gauged. |
| Delivery terms | FOB Ningbo or Shanghai; T/T, L/C at sight or D/P; repeat orders reuse the approved first article. |
Packaging and delivery
Parts are packed to protect the finish:, interleaving, polybags or formed trays are matched to the surface, in sealed cartons on export pallets, with documents issued to your instructions.
