Ratnashri Aluminium Pvt. Ltd. is a joint venture of Raajratna Group of Companies and Rolling Mills (India) engaged in manufacturing of stainless steel products for more than four decades.
Ratnashri Aluminium is an ISO 9001:2015 & ISO 14001:2015 certified company, mainly engaged into manufacturing of Aluminium Extrusion Products like Profiles, Sections, Solids(remove) etc. having a huge market with varied industrial as well as architectural uses. The company has set up an Exclusive plant with imported machinery & best available technology at Village: Rajpur, Taluka: Kadi, near Ahmedabad. The plant is equipped with highly technical machinery and testing equipment’s like spectrometer, hardness tester etc. Also, we have hired a team of the best technical and managerial staff to achieve our goals.
Our company utilizes advanced oil fired/gas fired fixed hearth reverberatory melting furnace with regenerative burners, with a bath capacity of 6 MT. We operate two Hot Top Casting tables designed to cast billets with diameters of 5 inches and 7 inches. The molten metal undergoes treatment with different type of fluxes and eco-friendly nitrogen degassing, and its composition is determined using a Direct Reading Spectrometer. Raw materials, along with necessary master alloys of Silicon, Magnesium, Manganese, Copper and Chromium are charged into the melting furnace.
Once the molten metal reaches the required temperature, dross is removed from the surface to create a clean bath. The molten metal is then cast into approximately 6-meter long aluminium alloy billets using the Hot Top Casting method. These billets are cut at both ends and fed into a gas fired homogenizing furnace, which aims to eliminate and reduce chemical element segregation, dissolve secondary phases, and improve the alloy’s microstructure and properties. The billets are subsequently cooled down in a cooling chamber and stored for use in the aluminium production process as required. This efficient and environmentally conscious process ensures the production of high-quality aluminium alloy billets ready for further processing and application.
The extrusion process begins with the heating of aluminium billets, tailored to the specific alloy type for optimal malleability. These heated billets are then pushed through a pre shaped die, forming the desired profile. The extruded profiles are rapidly cooled using media such as air, fog, or water to set their shape and physical properties. Once cooled, the profiles are stretched to straighten them and relieve internal stresses. They are then cut to the required lengths. Rigorous inspections at every stage ensure that our extrusions meet the highest standards. With two in house PLC controlled hydraulic presses imported for 5-inch and 7-inch profiles, the company is equipped to cater to a wide range of requirements, from miniature profiles to large sized profiles, sections & bars.
At Ratnashri Aluminium, we pride ourselves on offering premium-quality powder-coated and anodized aluminium products. Our powder-coating process provides a durable, weather-resistant finish, making it ideal for outdoor applications and ensuring that your aluminium components withstand the toughest environmental conditions. In addition, anodizing offers an advanced protective layer that enhances the corrosion resistance of aluminium while improving its aesthetic appeal. This process also allows for greater customization of colors, textures, and finishes, meeting both functional and design requirements. Whether you need aluminium profiles for industrial use or architectural purposes, our surface treatments ensure lasting performance and exceptional visual quality.
Our commitment to innovation extends to our ability to manufacture fully customized industrial components that align with your specific part requirements. We understand that industries often require components that are tailored to unique applications. That’s why we offer a flexible approach, working closely with our clients to understand their exact needs, from precise dimensions to complex geometries. Utilizing cutting-edge machinery and advanced production methods, we produce aluminium components with unparalleled precision. Whether you need small parts or large-scale sections, our expertise ensures that each piece is manufactured to your exact specifications.
