Artificial vision and augmented reality for the mold sector

INFAIMON is collaborating with the Portuguese company Arqtech on the Intelligent4DMoulds project to optimize mold design, production, and quality control. In this article, we show how the combination of machine vision and augmented reality offers the perfect solution for achieving zero-defect manufacturing.

Optimizing tool production in the factory

Portugal is among the world’s leading mold manufacturers, particularly in the field of plastic injection molds (ranking eighth in the world and third in Europe), exporting more than 85% of its total production. The mold industry is comprised of approximately 540 companies that create around 11,000 jobs in the country. The Intelligent4DMoulds project aims to research the mold production process and develop a technologically innovative system that will include new mold manufacturing processes using computer vision and augmented reality techniques. The project is co-funded by the European Regional Development Fund, the COMPETE 2020 Program, and the PORTUGAL 2020 Cooperation Agreement. According to forecasts, these techniques will reduce production costs by up to 40%, increasing the competitiveness of Portuguese companies in the domestic and international markets. Combining the potential of both technologies will make it possible to define and identify existing problems in each design and manufacturing process and assist in their resolution.

Automatic inspection of dimensional and geometric analysis of molds integrated into CNC machines

Numerical control machining, or CNC machining, is an automated turning and milling process in which material is removed from a block using a rotating tool. In this first module of the project, three-dimensional information is captured from the molds using laser triangulation technology provided by INFAIMON, which enables high-precision metrology of the entire mold, even on the CNC machine table. Advanced algorithms for analyzing and processing images on 3D point clouds make it possible to identify areas of the mold that do not conform to the reference 3D model.

Remote assistance with augmented reality

Remote connectivity facilitates a collaborative environment in which all stakeholders can monitor and validate the design and testing process of the molds being built. The project incorporates an augmented reality system, based on holographic technology for error detection, which virtually shows the operator the areas of the mold that require attention.
