The right information helps you with troubleshooting and upgrading your product
Analysis of fractures and defects in products
Analysis of fractures and defects in the product is an important discipline in the manufacturing industry and is used in the development of new products and in the improvement of existing products. Complex problems on the production line are not easily solved. In such cases, often the companies do not have enough resources, knowledge and analytical methods to ensure a comprehensive approach to the problem. LOTRIČ Metrology laboratories are your partner in problem solving, using chemical and mechanical methods in the field of polymer technology and metallurgical sciences.
Testing the properties of materials
Changes in the properties of ABS materials
With the method of artificial aging, we detect changes in the properties of ABS materials.
By testing materials, even in the product manufacturing phase, many problems can be avoided in advance. LOTRIČ Metrology helps you in various fields – mechanics, metallography, polymer technology and chemistry.
