Quality starts with raw materials
The quality of raw materials varies. At Grothe they are precisely analysed and inspected before passing on to further processing in-house or to the customer. Only outstanding raw material will give a perfect end product.
Efficiency through advanced technology
New technology enables us to accelerate test runs and analyses. The development and quality assurance processes become shorter. Working with the customer, Grothe can bring variable or new raw material qualities into production faster and with better stability.
Stable processes for reliable color consistency
Raw materials are prone to change. The quality of clay changes all the time, since new deposits have to be opened up and, given the varying nature of clays, different firing parameters arise. To maintain reliable colour accuracy over long periods is a costly, complex and demanding undertaking. With Grothe products, production of the long-lasting bond of clay substrate, colour and finish remains constant over many years.
Manufacturing & Quality
Care and the strictest controls
The best-quality raw materials and maximum precision are prerequisites for a good product. But only continuous monitoring and evaluation of production and inspection processes, supported by the latest technology, guarantees the reliable quality standards our customers need for the further processing of their own products.
