This Stamped Sheet Metal Frame Corner Connector is a frame corner connector that joins two profile ends at right angles, pierced for self-tapping screws. 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
What defines this frame corner connector on the print is the formed envelope and its faces, measured on the CMM at first article and by gauge in production.
Die work, pressing and finishing sit on the same floor, so feasibility questions are answered at the press, and the die record stays with your part number.
From coil to finished part
Production follows a fixed route: the blank is stamped and formed in a single die sequence, with in-die sensing watching critical features on every stroke.
Route cards follow every order through the shop, and the same setup is reused on the next call-off.
Materials and finishing
Our stock list runs to SPCC / DC01 carbon steel, HSLA and galvanized sheet, 304 / 316 stainless, aluminium and copper, with the grade for this frame corner connector agreed on the drawing.
Surface treatment is picked for the duty it will see: pre-galvanized, with zinc, nickel or chrome plating, powder coat, e-coat and passivation available, It is fixed on the drawing, so repeat orders never reopen the question.
Quality control
The sheet metal frame first article goes on the CMM, with threads gauged to class. For this frame corner connector 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
You will find the part in vehicle, equipment and enclosure programmes in both OEM and aftermarket supply.
Customization and options
The options most often changed:: grade and finish for the environment, piercings, flange direction and packing format, and the batch pattern – sample, pilot run or scheduled production.
A sheet metal frame carries one job in the assembly, and every tolerance on it exists to protect that job. We hold the critical sheet metal frame dimensions with gauges and first-article checks rather than relying on the drawing alone.
Specifications

| Samples | First-article samples ship with a dimensional report and material certificate, and any deviation is corrected at sample stage, Production starts only after your written sign-off. |
| Materials | pre-galvanized steel, 1.5 mm; mill certificate and heat-number traceability supplied with the first article. |
| Surface finish | pre-galvanized; alternatives quoted against the drawing. |
| Processing | progressive stamp – a frame corner connector that joins two profile ends at right angles. |
| Equipment | Press shop with 5-250 T mechanical presses and dedicated dies; first articles and batch samples are checked on the CMM. |
| Tolerance | ±0.10 mm hole pitch; ±0.5° right angle; 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:, interleaves, bagging or tray packing is selected by finish type, in sealed cartons on export pallets, with documents issued to your instructions.
