Artificial Vision Solutions for the Plastics Industry

Sentinel Vision develops and integrates artificial vision systems for inspection and quality control in the plastics industry, covering all stages, from injection and extrusion to finishing and final packaging.
Our solutions ensure dimensional accuracy, aesthetic uniformity, and complete traceability, reducing waste and increasing production efficiency.

Make your process smarter.
Enhance quality control with AI, 3D vision, and automated inspection.

• Injection defects (flow lines, bubbles, burn marks, or flash)

• Thermal deformations after cooling

• Thickness variations in extrusion and dimensional inconsistency

With our vision systems, it is possible to detect all these issues in real time, before they affect production or final quality.

• High-resolution 2D and 3D industrial cameras with telecentric optics

• Accurate measurement of thickness, diameter, and ovality (± 0.05 mm)

• Laser triangulation and structured light for profile analysis

• Coaxial and diffuse lighting for highlighting micro-defects

• Automatic identification of bubbles, scratches, inclusions, stains, or filling defects

• Deep learning algorithms trained with real production data

• Classification between visual and structural defects with self-learning capabilities

• Control of tolerances, angles, and post-injection deformations

• Multilayer calibration and optical correction with millimetric precision

Direct feedback to PLCs, SCADA, and MES systems

• Automatic alarms, inline rejection, and production statistics

• 100% automated inspection without human intervention

• Fast ROI, with an average investment return in under 12 months

• Modular and scalable systems, adaptable to any injection machine, extruder, or robotic cell

• Universal compatibility: EtherNet/IP, PROFINET, EtherCAT, OPC-UA, among others

• Incomplete part inspection: inspection with a 0.1 mm tolerance and automatic part positioning correction.

• Automotive fuse boxes: high-resolution optical inspection with coaxial and diffuse lighting, ensuring visual uniformity.
