ADVANCED FULLY AUTOMATED ALUMINIUM FOUNDRY

We are an aluminium high-pressure foundry specialized in the casting and mechanical processing of products for various applications. Lumi Team produces casting parts for organizations across different sectors such as lighting, automotive, heating, electronics,
medical technology, etc.

Advanced casting machines with real time casting system guarantee products surpassing expectations of most demanding clients. Our DAK series FRECH cold-chamber die casting machines with 800 and 950 tonnes locking force, work along KUKA pick and place robots with product completeness check system in two automated casting cells. We use top aluminium alloys for die casting and can die cast any workpiece up to 10 kg heavy. We work with trusted and reliable suppliers that can deliver a quality certificate and document the chemical composition of alloys sold. In our automatic refining process the alloy is further prepared for casting to ensure maximum quality. The casting cells and smelting furnaces are completed by automatic 30 tonnes TECNOPRES KZP 30 trimming presses in an effort to fully automate the whole casting process making it more efficient, cost-effective and fast.

A well designed and manufactured die casting mould is key for a successful die casting process. Our expert process engineers design die casting moulds using the latest CAD software. After obligatory die casting simulations, moulds are later manufactured at our machine park, taking that responsibility off the shoulders of our clients.

OUR DIE CASTING MACHINES

FRECH LOGO

In our foundry we use the latest generation of FRECH DAK SERIES cold chamber die casting machines with 800 t and 950 t locking force and real time casting system. At the casting stage we focus on achieving an optimum distribution of temperature in the mould and temperature control throughout the process. Real time system allows high-precision control of piston movement for uninterrupted aluminium casting in the mould. Therefore, we achieve the highest durability and structure uniformity greatly surpassing traditional methods.

PRODUCTION PROCESS

1. MOULD DESIGN & MANUFACTURING

A well-designed mould guarantees a smooth and efficient manufacturing process to meet all expectations at the final stage – our expert process engineers design the moulds using the latest CAD/CAM software.

2. ALUMINIUM ALLOY

The first stage of the casting process is crucial – with low quality raw materials, the casting will not match expectations. That is why we have chosen to work with trusted and reliable suppliers that can deliver a quality certificate and document the chemical composition.

3. ALUMINIUM SMELTING

Aluminium is smelted in our 1000 kg capacity tilting gas furnace in extremely high temperatures. The furnace operates with a 400 kg/h efficacy.

4. LADLE REFINING & ALLOY CLEANING

An inert gas flowing through the head moves to the surface of the liquid metal capturing solid inclusions and hydrogen. The refining process is crucial, since it guarantees low gas content in the alloy – it reduces the volume of air retained in the die castings to the minimum. After refining, melting loss is removed from the metal surface. The cleaned alloy is transferred into the holding furnaces in the casting cell and is ready for further processing.

5. HIGH PRESSURE DIE CASTING

Our priority is to achieve the highest durability and structure uniformity greatly surpassing traditional methods. We use the latest generation of german FRECH DAK SERIES casting machines with real-time casting capabilities. The quality is further improved by process automation – our casting machines work along with robots in the automated casting cells. Quality is monitored by a set of 8 cameras that individually examine each die cast as soon as the robot takes it out of its mould.

6. MANUAL OR AUTOMATIC TRIMMING

We offer manual as well as automatic trimming services on our 30 tonnes TECNOPRES KZP 30 trimming presses. Their trimming knives are custom made for each die-cast.
