For more than three decades, WAMGROUP® has been amongst the worldwide leaders in the manufacture of screw conveyors and feeders with an annual production of over 15,000 units in sizes varying from a screw diameter of 150mm to 750mm for standard production and on request up to 4,000mm for special applications such as water lifting screw pumps.
To date, WAMGROUP® has produced a total of over 250,000 numbers of tubular screw feeders/conveyors and more than 60,000 trough screw conveyors of various lengths and configuration.
With headquarters located near the northern ltalian town of Modena, the Group currently employs over 1400 staff worldwide.
Since in 1969, Vainer Marchesini, founder and current chairman and C.E.O of the Group manufactured his first Screw Conveyor, the name WAM® has come to stand for innovation in Bulk Material HandIing Technology and Equipment Supply.
The manufacture of the mechanical components by custom-built machines and jigs guaranteed perfect centering and parallelism. For the fabricated parts and for the assembly of the augers too, special machines and tools were installed in order to obtain the highest possible quality and the smallest possible tolerances. The objective was to achieve higher throughput rates without altering the screw diameter. One condition for higher r.p.m., however, was a particularly suitable shaft coupling. The solution consisted in mounting splined shafts and welding of matching splined bushes onto the centre pipe of the auger.
The new technology soon was applied to other industries and modified according to their requirements. After the asphalt industry came cement milling, lime and plaster processing, screw conveyors for de-watered biological sludge, for animal feed and flour mills, metering screw feeders for the chemical, the food and the glass industry, to name but a few.
In 1978, the former artisan business turned into a private joint-stock company. Meanwhile, butterfly valves, slide valves and dust collectors had been added to the product range. The successful philosophy of serial production led the management to open new manufacturing units. 1979 saw the setting up of SPECO® - manufacturer of wastewater treatment equipment, such as water screw pumps, grit classifying and recycling screws, screw screens and screw compactors.
In 1983 MAP®, specialists in the manufacturing of industrial mixers, blenders and dust conditioners-granulators, started business. Only a few years later, MAP® granted its first manufacturing licence to a Japanese manufacturer of industrial mixers.
In 1986, the development and production of complete computer controlled dosing and weighing systems was well under way.
One year later, TOREX® supplied their first rotary valves followed by flexible helix conveyors, telescopic loading spouts, pinch valves and level monitoring equipment.
Thanks to an experienced and determined management, great dedication to R & D
and a dynamic team, both the Italian manufacturing companies and the foreign subsidiaries have succeeded not only in better assisting long-term customers but also in the early conquest of new markets and industries.
Although today a Holding controls the companies of the Group, one fact has not changed since the beginning: the goal of each company and individual member of staff still is and always will be to offer high quality mass-produced items designed for the world market, at an attractive price.
WAMGROUP® has been certified according
to ISO 900l quality management since 1994 and was later upgraded to VISION 2000 certification.
