A Visit to Tesla's Stamping Workshop

This is a Shanghai port terminal where nearly 4,000 Teslas are queued for shipment worldwide.

The Tesla Shanghai plant opened two years ago and now exceeds the US plant in deliveries; in 2021 Shanghai accounted for 51.7% of global output.

Behind high output is high automation, and automation requires stable production lines.

Atonm Smart Technology, as a supplier to Tesla Shanghai, brings you into the stamping workshop to see how stamping production is ensured and how Metal Double-Sheet Detectors are used.

Understanding the stamping workshop

Stamping is the first of four major automotive processes; good cars start with stamping. The process forms panels from blanks using dies. Press specifications, die precision, sheet performance, and cleanliness determine final part quality.

Large heavy panels can use suction control or vibration to avoid double-feeding, but for interior panels and small parts, vibration alone may not prevent double feeding.

Tesla Shanghai uses Atonm's MDSC-1000C high-performance communication Metal Double-Sheet Detector, which handles dozens of material conditions and has run stably for years.

Features include adaptation to multiple metal materials and thicknesses, non-contact detection that does not damage surface precision, RS485 communication for integrated automation lines, and detection speed up to 1200 pcs/min, exceeding automatic feeding needs.

Atonm focuses on solving industry pain points for high-reliability automatic feeding in the new energy vehicle era.
