v2.4 · YOLOv8 + Mask2Former · Jetson Orin edge runtime
Edge computer vision for metal manufacturing. Inspect every part. At line speed. With an audit trail your buyer will accept.
One GigE Vision pipeline. Three transformer-backed model heads. Built for the three inspection problems that decide whether a shipment passes PPAP.
OCR
Transformer OCR trained on embossed, etched, laser-marked, and dot-peen steel. Lifts part numbers, heat codes, cavity IDs, and IATF traceability batches under glare, scale, and oil.
TrOCR backbone · 28 character classes · 99.6% CER on dot-peen

Object Detection
YOLOv8 fine-tuned on casting and forging surfaces. Flags porosity, inclusions, cold shut, misrun, hot tear, scab, and foreign object debris frame by frame at conveyor speed.
Sub-100ms latency · 1240 PPM throughput · ONNX on Jetson Orin

Segmentation
Mask2Former predicts defect boundaries to sub-pixel precision. Drives automatic scrap, rework, or accept decisions tied to GD&T tolerances in your Control Plan.
Sub-pixel masks · IoU 0.91 · Cpk uplift 1.33 to 1.67
Learn more ›The console
Every frame from every station, scored in under 50 ms, written to an immutable event log, and surfaced in a console designed for quality engineers, not data scientists.
Cpk, Ppk, X-bar R, and PPM trending streamed per part. Control limits recomputed every shift.
Anomaly drift fires SMS, email, MES tag, or Andon light through OPC-UA or MQTT before scrap stacks up.
Every inference, every override, every model version signed and hashed for IATF, AS9100, and ISO 17025 review.
See it run
Watch the system score a casting station live. Defect overlays, segmentation masks, OCR reads, and the SPC dashboard responding in real time.
The PRP advantage
Twenty-five years of trade between Indian foundries and Tier-1 buyers in Europe, Japan, and the Gulf. A defect corpus of 14 million labeled casting and forging frames no general-purpose vision model has ever touched.
Four steps from a Basler ace camera on the line to a signed entry in your QMS.
01
GigE Vision cameras, telecentric optics, and structured LED domes mount over your existing station. Zero line rework. PoE in, RJ45 out.
02
Models specialized to your part family run on-prem on Jetson Orin or x86 with a T4. 47 ms per frame, 1240 PPM, fully air-gapped.
03
Pass, rework, or scrap signaled over OPC-UA, MQTT, or hard-wired GPIO to your PLC, robot cell, or Andon stack.
04
PPAP, FAIR, and IATF 16949 packs generated on demand. Per-part imagery, defect overlays, and model version signed and stored seven years.
Stack
Drops into a brownfield line in under a week. Streams to SAP, Oracle, Ignition, Wonderware, Tulip, or your custom MES with first-class adapters. No rip and replace.
Compliance
Every inference SHA-256 signed, NTP-timestamped, and stored alongside the source frame, model version, and camera calibration. PPAP, APQP, and FAIR packets export in one click. Once your auditor walks the trail through MetalSense, switching is not an option.
Where we run
Ductile iron foundries. Aluminum HPDC cells. Drop-forge hammers. Cold-rolled sheet lines. Investment casting wax rooms. We deploy where the part is hottest, the lighting is worst, and the tolerance is tightest.
One station. Thirty days. Real Cpk uplift, real PPM reduction, real numbers your buyer can verify.
