Haomei

Soft alloy aluminium
extrusion plant

Industrial Park - The new HAOMEi plant, inaugurated in 2005, includes a foundry with 8 furnaces that produce 6xxx series alloys including 6060, 6061, 6061A, 6063, 6082, 6005, 6005A.

Four homogenisation furnaces guarantee the chemical-physical stability of the billets and their mechanical properties. A modern laboratory with a computerised and laser system verifies that each billet demonstrates quality and stability in compliance with international standards.

In HAOMEI we cover the entire production process of extruded aluminum: from the foundry and casting of ingots and billets, to the realisation of the dies, to carryout the extrusion of the profiles, to the anodising and powder coating, up to the thermal break, and additional mechanical processing.

Today, the plant covers a total area of approximately 1,000,000 m°, of which approximately 550,000 are covered.

Production is automated and the main functions are completely computerised with the importation of the best technologies and production systems from Japan, Taiwan, the United States and Europe.

Foundry and casting

The factory has 4 furnaces for the casting billets with a vertical "hot spot" technique, 4 horizontal homogenisation furnaces and 1 degassing and in-line filtration system, complete with new-concept ceramic filters.

HAOMEI is able to produce continually 24 hours a day for 365 days a year and supplies homogenised billets for extrusion with high technological content and high metallurgical level, thanks to a totally computerizsd laboratory.

In addition to the 6xxx series alloys, we have developed the 1xxx, 2xxx and 5xxx series, greatly improving their mechanical properties whilst simultaneously offering the opportunity to replace certain steel components in different industrial sectors.

Die development

HAOMEI has dedicated an area of approximately 20,000 m² to the complete production and repair of dies, and have over 100,000 active dies.

Profile extrusion

We can supply various industrial sectors with constancy and efficiency: the estimated annual extrusion productivity is around 150,000 tons.

The department has 34 active lines, mainly composed of Chinese and Japanese Taiwanese installations, with American Gramco pullers and Italian benches:

1 press of 4,000 tons
1 press of 3,600 tons
2 presses of 2,500 tons
5 presses of 1,800 tons
8 presses of 1,500 tons
9 presses of 1,250 tons
12 presses of 1,000 tons
4 direct presses of 600T

The custom made product profiles have a minimum thickness of 0.8 mm, guaranteeing maximum tolerances.

Anodising

The workshops for anodising treatment, recently renewed, are developed on 7 latest generation lines.

Two of these are electro-colour; one is reserved for the polishing of clean profiles both mechanically and manually; and one line is used for nickel plating and special treatments.

The plant consists of 188 tanks with a maximum length of 12,000 mm, and 31 rectifiers with a total power of 60,000 A.

Powder coating

The epoxy and /or polyester painting department includes 7 lines of which 5 are vertical and 2 are horizontal. One of these lines is interchangeable and can be used both for painting and for electrophoresis or PVDF treatments.

The maximum length of profiles for painting on the horizontal systems is 12 linear metres, and 7 metres on the vertical lines. All lines are computerised and use Swiss Gema and Italian Trevisan technology.

Mechanical processing

The department is constantly updated with state-of-the-art machinery to provide the customer with a product that is always competitive on the global market.

In addition to lathes, simple and high precision cutters there is in operation:

7 double-headed Emmegi cutting-off machines
1 automatic Emmegi drilling machine
1 automatic Emmegi shearing machine
3 Emmegi CNC's with numerical control with 4 and 5 axes

The area dedicated to additional machining for profiles, recently expanded by a further 9,000 m² in September 2010, and now covers around 25,000 m². The workshop also includes two new assembly lines for the thermal breaks, one for European and Asian markets and the other for American and Australian markets.
