What our customers say

“Alutrim Europe GmbH produces high-quality visible parts for the automotive interior sector. To ensure high quality, our raw material must be adequately protected against contamination. By using the seal-IT protective cover, we meet this requirement in the area of granulate provision. The covers from seal-IT help us minimize contamination from external sources and thereby guarantee high quality for our customers. "
Marcel Gaszczak (M.Eng.) - Head of Production Technology
Alutrim Europe GmbH
“We have been looking for an octabin cover for our raw materials for a long time. The fact that a functioning bulk material cover like the one from seal-IT is necessary and worth the price is shown by the material value of a full octabin. For us, that's around € 6,000. "

Michael Heitlindemann - Head of Injection Moulding
Heinze Kunststofftechnik GmbH & Co. KG
“We process raw materials for around € 60,000 every week and have found an optimal bulk material cover for this with the seal-IT octabin protection. Ever since we have been protecting our bulk goods with the seal-IT Cover, we have not had any failures or repairs to our hot runner moulds. "

Hartmut Schmitt - Head of the Injection Molding and Tool Making Department
ProMinent GmbH
“After initial skepticism, the seal-IT bulk goods cover convinced us. As part of the 'Zero Granulate Loss' initiative, the seal-IT bulk goods cover has contributed to a sustainable circular economy. With the help of the seal-IT cover, order and tidiness, as well as "good house keeping" in general, could be significantly increased. "
