At the dawn of the new millennium, in 2000, Elleci revolutionised the technique for manufacturing composite sinks, developing and patenting the GPS (Granitek Production System), an innovative production system that has become the benchmark in the sector. It is a system that still stands out in the international industrial landscape as an example of thoroughly Italian excellence.

The unique feature of the system is the dynamic rotation of the moulds, an operation that makes it possible to distribute the mass of the sink more uniformly and more compactly. This means that the sink has better resistance to thermal shocks, impacts and scratches, and that its surface is easier to clean.

THE PRODUCTION SYSTEM THAT MAKES ALL THE DIFFERENCE

The GPS system it is now the ultimate expression of moulding technology for thermosetting composite materials in the field of kitchen sinks.

Physical and chemical tests, for example, show how reducing the cycle time in the production process damages the product, weakening the chemical bonds of its components. Elleci applies an appropriate balance in all its production processes between production optimisation and undisputed product quality = durable sinks!

ELLECI PATENT: GRANITEK PRODUCTION SYSTEM

  • Better impact resistance (+30%).
  • Better resistance to thermal shocks (+100%). Over 7,000 hot water cycles (over 90°C) and cold water cycles (15°C), 20 years of daily use.
  • Better resistance to high temperatures (+30%).
  • Better appearance of the sink.

Moulding process using the GPS system

The GPS system is a series of machines that make it possible to a composite material produced using a mixture of acrylic resin loaded with quartz particles of various sizes, depending on the product to be made.

The heart of the system is the moulding press. Because the press operates a dynamic moulding process, the unique feature of the machine is that it is possible to obtain a product with a substantially uniform distribution of all of the components making up its mass.

International Patent No 1 415 794 B1

Traditional Moulding System

All of Elleci’s competitors use a Static Moulding System, traditional technology that does not enable a balanced distribution of all components (acrylic resin and quartz) in the mass of the sink. This is a basic chemical principle designed to obtain the best mechanical characteristics.

Example of a product made with traditional technology, where the components (in particular the quartz) are distributed in a non-uniform manner:

Elleci Moulding System

The GPS System has invented a Dynamic Moulding System that enables a substantially uniform distribution of all of the components included in the mass of the sink.

Example of a product made using dynamic moulding, where the components (in particular the quartz) are distributed in a substantially uniform manner:
