Tool making

With more than 50 years of tradition, LTH Castings has specialized in development and production of die-casting tools up to 40 metric tons, trimming tools and complex clamping devices.

A dedicated workforce in our plants Škofja Loka and Ohrid enables us to handle high volume programmes, high flexibility and short manufacturing times.

We provide

• Consultancy in product development and advice in Aluminium die-casting and machining, all in close contact with your R&D.
• Development and prototypes
• Computer simulations (mould fill and solidification simulation, computation of residual stress and distortion, computation of mechanical properties).
• Finite element analysis (FEA)
• High education levels and flexibility in new products and modifications.
• State-of-the-art technology and CAD/CAM/CAE systems (CATIA, Siemens NX, ProEngineer, NCG CAM, Magma, Abaqus)
• Development and simulation of complex clamping devices and machining processes. 

In order to ensure the highest quality products, we build on simultaneous engineering, continuous improvement and utilize inspection practices throughout our manufacturing processes. With our 24-hour repair-service-support, we reduce production costs and apply our experience in every new project.
