Company specializing in aluminium die casting
La Cibek die casting
A company specializing in aluminium die casting, La Cibek has been operating since 1968 in the aluminium and zamak sectors, with a constant commitment to technological innovation and control of production processes, guaranteeing a high quality of the die cast part.
Always attentive to the evolution of the die casting process, La Cibek is now able to offer competitive solutions that comply with the standards required by the market.
A company specializing in aluminium die casting, it has over time developed a specific expertise in the production of castings for sectors such as: industrial automation, professional appliances, electronics, electrical, LPG-methane systems for cars, agricultural machinery, industrial cleaning machines, hydraulics, pneumatics, and measuring instruments.
Work philosophy and market approach
Our work philosophy originates from a fundamental assumption: close cooperation with the customer for the project development in a CO-DESIGN logic.
Design Skills and Cost Optimization
The design and simulation skills of filling and in-mould temperature analyses allow the reduction of critical casting areas. Subsequent accurate machining also allows the production of high-quality castings.
Our company, specializing in aluminium die casting, adopts advanced technical solutions to minimize the mechanical operations required for die casting production, thereby achieving a significant reduction in production costs
Within a short time frame, La Cibek die casting is able to respond to the most demanding enquiries with innovative solutions. Extreme organizational and production flexibility allow La Cibek to handle even small batches, with a minimum limit of 1,000 shots, at competitive prices.

– ALUMINIUM DIE CASTING IN HISTORY –
Evolution of die casting
Die casting was created in the United States from an idea by Herman Doehler, co-founder of Doehler-Jarvis, who developed the first die casting machine. Also in the United States, the world’s first aluminium die casting for commercial use was produced in 1915.
In 1938, Triulzi of Milan, by copying an old “Polak“, designed and built the first horizontal machine suitable for pressure casting aluminium alloy. With this technology, the old casting concepts used until then were surpassed, namely sand and shell casting
The presses initially were not equipped with a toggle locking system, nor with multiplication forces from inert gas (Nitrogen) cylinders; they used pumps to feed large compressed water cylinders.
Over the years, dozens of companies were founded in the province of Brescia, taking advantage of technological evolution to produce die castings more and more efficiently and competitively with closed-loop injection systems, thus creating an aluminium die casting district centered in Brescia.
PRODUCTION METHODS IN ITALY
Die casting was initially called pressure mould casting. It is a foundry process where molten metal, aluminium or zamak, is injected at high pressure into a mould. This particular process was initially used in the USA in the second half of the 1800s.
The mould used is actually composed of two half-moulds, usually in hardened steel. Given this characteristic of the mould, it is only possible to cast materials that have a melting point at a lower temperature than the one at which the mould was built.
The materials used in die casting are predominantly aluminium and zamak (zinc alloys). The pressure needed to inject the molten metal is generally quite high and can range from 20 to 1500 bar. The pressure can be maintained for the entire duration of the process (until the metal solidifies).
Following the injection phase, the mould cooling phase occurs, which is carried out using a cooling liquid inside the mould through thermoregulation circuits.
At La Cibek, the aluminium die casting cycle is completely automated, thus ensuring high productivity.
HOT CHAMBER DIE CASTING
Hot-chamber die casting takes place thanks to a furnace that allows for better control of the melting temperature and higher productivity. In hot-chamber die casting, the required pressure is lower than in cold-chamber die casting and rarely exceeds 130/140 bar.
Hot-chamber die casting is used primarily for zinc alloys (zamak) and allows for a high-quality surface finish.
The cold-chamber process occurs with less control over the temperature of the liquid shot and has lower productivity, as it requires more time in the injection phase.
Cold-chamber die casting allows for a wider choice of materials (aluminium and also zinc alloys) and the ability to reach higher pressures (1500 bar).
