Walton is going to install most advanced machineries at its nut, bolt and screw manufacturing unit at Chandra in Gazipur aiming to raise the production capacity of the existing unit.
Mentionable, fasteners are one of the most important light engineering items, which are used in heavy engineering as well as different manufacturing industries like furniture, automobiles, electrical and electronics appliances etc.
Earlier, most of the local demands of fasteners were met with the imported items, as a result, the country has to spend lots of foreign currencies. Besides, both the importers and the users had to wait for couple of months to get the imported items. But, this import dependency had been reduced with the start of local productions of nut, bolt and screw by Walton in 2017.
Abdur Rouf, head of Industrial Solutions Department of Walton, said they were manufacturing world-class nut, bolt and screw with sophisticated machineries at Walton Hi-Tech Industries.
He said that the annual production capacity of their unit is around 1800 tons whereas Walton uses about 360 to 400 tons fasteners annually to manufacture its wide ranges of hi-tech appliances.
Prihish Kumar Saha, head of Screw RnD (Research and Development) Department of Walton, said they are producing different types of fasteners at Walton nuts, bolts and screws manufacturing unit, including self-tapping and self-drilling screws of 2 to 10 millimeter (mm) diameter and 5 to 75 mm length, hexagonal and alien bolts of 8.8 and 10.9 grades, machine screws and hexagonal nuts.
“We installed Taiwanese dies and machines in the production line. In addition, we are following world’s latest production process like wire drawing; spheroidize annealing; pickling, phosphating and metal soap treatment (PPM); cold forming; heat treatment and electroplating. Walton screws and bolts are made of high quality boron alloyed steel whereas nuts are made of highest standard carbon steel”, he said.
Saha also informed that 100 percent heat treatment furnace is used in Walton fasteners. To assure internal standard, world’s latest German and US technologies testing equipment like stereo microscope, metallurgical microscope and micro hardness are installed at the research and development center.
They conducted the structural test of the produced fasteners through magnifying these up to 1000 times with the metallurgical microscope. Also, hardness of the fasteners are tested with micro hardness equipment. Passing through a test of 96 hours salt spray, Walton fasteners have excellent corrosion resistance for indoor and outdoor use.
According to Walton authorities, they are using their own produced nut, bolt and screw in the production process of fridge, air conditioner, LED television, compressor, various sorts of electric fans, rice cookers, blenders, gas stove, switch-socket, LED light etc.
