Integrated Production Facilities

From CAD to shipping

Masson-Marine benefit from integrated production facilities for their entire product range. Gearbox components are thus manufactured in accordance with a machining, heat treatment, and grinding sequence. These are followed by the assembly steps and testing of 100 % of our production. Such autonomy provides Masson-Marine with perfect control over their products, and with a strong ability to respond.
Our clients therefore benefit from quality service, whether with new equipment or with spare parts. The premises in Sens also include the research and applications department providing technical support to our clients and proposing tailor-made solutions.
