Thoni Alutec—Aluminium Foundry

Our aluminium foundry, which consists of a moulding area and a melting area, is the centre of the whole casting process. In the case of job production and small lots, we use sand moulds. However, large lots of castings up to 90 kg in weight are produced by die casting. We always ensure high quality of the raw materials and the melting process. We are constantly improving our patterns and moulds. In addition, the finished product is always thoroughly inspected, so that it meets customer expectations and international standards.
Here at Thoni Alutec, employees have vast knowledge and experience and they are constantly gaining new qualifications. In our facilities, we use cutting-edge technologies, machines and devices. All of the above have made Thoni Alutec one of the world leaders in aluminium casting.

Melting Area

We have 6 main process lines (4 at the sand foundry, 2 at the aerospace precision foundry), each with dedicated melting furnaces, both electric and gas-powered, as well as the main furnace for ensuring continuous pouring. That is why we are able to maintain efficient production using different processes and alloys based on international standards or the needs of an individual customer. The raw materials we use are provided by proven suppliers, and the whole melting process utilises state-of-the-art devices for reinement and modification of the molten alloy. The grade of the alloy is tested  on an IDECO device prior to pouring. Bubbling allows for evalauting the gas content, the level of refinement and modification. Thanks to the sophisticated equipment we use and our well-trained staff, we are able to ensure high quality of castings even at early production stages.

High Pressure and Low Pressure Die Casting Line

The line consists of:

  • over a dozen casting machines of different sizes and different numbers of parting line arrangemets
  • tilt-casting machines which eliminate pouring turbulence, used for production of castings with uniform geometry
  • LPDC machines of different sizes and functionalities

Electric and gas-powered furnaces for each unit

Different kinds of specialist equipment at Thoni Alutec allows us to produce castings of various sizes and shapes.

Core Shop

Our core shop provides casting cores for our casting lines: LPDC lines, gravity die casting lines (permanent mould) and the precision sand foundry. Based on the variety of different casting processes used at Thoni Alutec, the core shop has machines to produce the following types of cores:

  • hot box and cold box hollow cores
  • cold-box—7 types
  • hot-box—tests of new solutions at advanced stages
  • warm-air

Low Pressure Die Casting Line

The line consists of 5 specialist machines used for large production lots, e.g. for the automotive inductry. We also use it for intricate castings with sand or metal cores.

Here at Thoni Alutec, our recent investments have enabled us to use state-of-the-art, effective machines with unique pouring parameters and available mould sizes.

Sand Casting Line with Sand Reclamation, Heat Treatment, Quality Control, Nondestructive Testing, CNC Machining, Leak Tests and Assembly

The moulding lines in the aluminium foundry cover the whole process, starting from sand preparation, and ending with knock-out.

The line includes fully automatic sand reclamation units, used both for the ‘commercial’ and the aerospace precision foundry.

Technologically advanced moulding lines allaw for both large casting production (unique in the world) and smaller castings with complex shapes used in aerospace or automotive.

We specialise in the production of large and medium-size castings for industries such as: energy, mechanical engineering, aerospace, rail, medical, defence, automotive, agriculture, wind power etc.

The variety of shapes and the level of complexity of the castings we produce have made us a market leader in our field.

Aluminium Foundry Production

At Thoni Alutec, our services cover not only sand casting, permanent mould casting, and low pressure die casting, but also further process such as: fettling, heat treatment, CNC machining, painting, assembly, packing and delivery.

The required strength properties of the casting are obtained through heat treatment performed on 3 lines, including one NADCAP-certified line dedicated to aerospace production. This is a so-called special process. Its parameters are constantly checked, and the whole process is automatic. The control cabinets in the heat treatment furnaces control the process continuously. The process parameters are recorded in a database for later access.

Quality Control in Aluminium Foundry

The quality control process covers the following: chemical composition analysis, metallographic analysis, mechanical properties analysis, 3D dimesional inspection on CMMs and optical devices. We also perform NDT: penetrant, X-ray and ultrasonic tests.

Aluminium Foundry—CNC Machining Department

Thanks to implementing cutting-edge technologies and installing advanced CNC machines, our CNC machining department provides fully automated machining services.

Having over 50 CNC machines allows us to fully meet the requirements of the market both in terms of the component size and the lot size.

Dimesional inspections are performed by competent staff, who are constantly gaining new qualifications. The utilise state-of-the-art CMMs to meet your expectations.

To complete the full package offered, we perform leak tests (mostly with helium and water—bubble leak testing), painting (wet painting and dry coating) and assembly.

In conclusion, the products are produced in a controlled environment, i.e. on modern machines and devices, which are constantly maintained and operational. All the equipment for monitoring and measuring used in the productions process is periodically calibrated in certified laboratories. The raw materials used are purchased from approved suppliers. Before they are shipped to customers, all products undergo final inspections performed by qualified personnel.
