Extrusion
Aluminium extrusion is a technique to transform aluminium alloy into an extraordinary variety of products for consumer and industrial markets. Making the most of aluminium’s excellent malleability, the extrusion process creates shapes by heating billets of aluminium alloy to soften them and then forcing them with a hydraulic or ram under high pressure through special steel dies.

Maharashtra’s Ahmednagar based JM Aluminium has garnered expertise in this space over the years and emerged as one of the leaders in common alloy standard and custom extruded aluminium products. “We have vast resources and unparalleled technical competencies that allow us to produce the most comprehensive line of products in the extrusion industry,” says the company’s Managing Director Nikhilendra Motilal Lodha.

Die design & manufacturing
A die is the tool shape that the aluminium is pushed through to create the profile. Dies are made of tool steel. The die aperture, which corresponds to the desired cross section of the profile, is produced by spark erosion. JM Aluminium is a specialist in producing superior designs and manufacturers for complex multi-hollow and solid profiles.

JM Aluminium has experience includes manufacturing dies and tooling for all aluminium alloy groups. Dies are manufactured from high quality hot working tool steels and special alloy steels with high hot temperature strength and toughness for critical or high tongue ratio profiles.

Fabrication
A variety of methods are used in aluminium extrusion fabrication to achieve accuracy in the finished components. Aluminium not only offers many advantages due to its material properties. Aluminium is also extensively adaptable to fabrication and machining process. “Our expertise over almost two decades of custom aluminium fabrication also gives us vital perspective on how to accomplish the projects that other competitors might turn away,” claims Sudarshan Lodha, Operation Manager at JM Aluminium. The company offers a range of precise fabrication capabilities including precise cutting, milling, drilling, punching and bending.

The company’s automated milling machines results into increased output, as it is possible to have the production line operate without interruption for longer periods. Drilling is used to make or enlarge holes in the aluminium extrusions using a drill bit. Punching creates holes by using a punch press to force a punch into an extrusion placed on top of a die. It is one of the fabrication options for aluminium extrusion products to create multiple shaped holes in a variety of products. Bending is primarily used for shapes like boxes or enclosures, such as rectangular ductwork.

Finishing
Knowledge and experience of the finishing industry keeps JM Aluminium at the leading edge of technology and innovation, allowing our customers to access the latest and best fit finishes available. Powder coating has been long recognised for excellent finish quality in appearance and performance.

For quality painted finishes, JM Aluminium offers a full spectrum of colours, from matte finishes to high gloss. Anodising is the electrolytic oxidation process in which the surface layer of metal is transformed to allow it to provide protective, decorative or functional properties. “We are well placed to select the most suitable and cost effective method of anodising for our customers, as well as the most appropriate processor,” avers Sudarshan Lodha

Quality
“Our experienced professionals will advise you on the right choice as per the requirements and preferences shown by customers. At every stage from design, drawings, choice of materials, till completion, quality is encouraged in our system,” concludes Nikhilendra lodha
