Based on a sketch, drawing or sample from the customer, Comatra prepares production drawings for customer approval. Then we produce samples that are sent to the customer for testing and acceptance. It is a significant advantage that we have our own model workshop and can quickly and inexpensively produce models. Similarly for upgrade and product development.   We also contribute with cost-reducing proposals in relation to design and material selection.  Comatra has extensive experience and knowledge of which rubber compound will best achieve the function the customer wants.
