Technologies for underwater pelletizing from GALA

Apr 1, 2022

GALA has been the embodiment of innovative technologies in underwater pelletizing and drying for polymer, compounding and masterbatch processing, production and recycling applications for over 60 years. Within the MAAG Group, GALA develops tailored, turnkey underwater pelletizing systems and dryers. Its plants process polymers, hot-melt adhesives, color masterbatches, compounds, thermoplastic elastomers, soft and rigid PVC, chewing gum bases, and many other plastics and composites.

In addition to in-depth industry and product know-how and decades of experience, GALA and the MAAG Group are united by respect for our interactions with customers. Reliable performance fulfillment of customers’ needs and requirements is how we measure ourselves. GALA’s product range and services within the MAAG Group are consistently designed to achieve the results required by customers with maximum availability, support backup, and a strong sense of responsibility. The combined innovative strength and high qualification levels of the MAAG Group’s workforce guarantee the ongoing optimization of the systems and the sustainable development of new products and services in line with demand.

Research and development – together with the customer

The needs of our customers are the starting points for new developments. That is why GALA’s research and development activities as part of the MAAG Group often involve its customers. Projects are run jointly to analyze actual situations and define goals. To support customers in their product development, research and development tasks, or in the production of pellet samples for market launch, GALA operates pilot plants and test centers. They are also able to test finished underwater pelletizing systems in terms of their suitability for the given application. The state-of-the-art information, demonstration and research centers are equipped with processing systems such as compounders featuring single-screw and twin-screw extruders, as well as systems for the production of hot-melt adhesives, including for low-viscosity applications.
