Automation Engineering (AE) is the cornerstone of the manufacturing industry and at M&W it has been an integrated part of our business for decades. The goal of automation is to increase uptime, reduce defects and enable fully automatic operations. On a daily basis, this is helping our customers to optimize their operations and improve their profitability.

Electrical Engineering (EE) is the classical discipline of designing switch gears, control cabinets, power cables etc. The EE at M&W has been an integrated part of the business from the very beginning.

Mechanical Engineering (ME) is at the core of M&W, especially within the disciplines of mechanics, dynamics, thermodynamics and structural analysis. M&W has a dedicated team of mechanical engineers that design, engineer, build, test and document the product/solution. The design is either based on our standardised concepts which takes customers specifications into account or can be a development of a prototype. M&W offers an A to Z solution, and thus after the engineering has been performed, a dedicated team of inhouse machine operators, metalworkers and blacksmiths ensure the entire mechanical production. After production, the M&W mechanical and electrical engineers test the entire product/solution before shipment. As per requirement, a factory acceptance test (FAT) is performed before shipment.

Within M&W we recognise that a professional PM is the prerequisite for successful customer delivery. That includes execution of a project within prototyping, customising, product development or by large external customer projects. M&W has many years experience with executing projects both internally and at our customer sites worldwide.
