Welcome to LM Engineering!

Our manufacturing process begins with the use of virgin aluminium ingots, each with a certified purity exceeding 99.5%. This guarantees consistent quality and performance in every slug we produce.

Our high-capacity tilting furnace allows controlled melting of aluminium ingots, carefully avoiding excessive temperatures. Additives are introduced to limit gas absorption, improve recovery rates, and maintain uniform melt composition.

Molten aluminium is transferred to a launder through the furnace opening and feeds the rotary mould. Additional metal treatment in the launder further reduces gas entrapment and ensures homogeneity before casting.

The molten aluminium enters a rotary strip caster and solidifies into a continuous strip. The cooling process is carefully controlled to achieve the desired grain structure and mechanical properties.

The aluminium strip undergoes hot rolling to refine its micro-grain structure, enhance mechanical properties, and prepare it for further processing with optimal grain uniformity.

The aluminium strip is cold rolled at room temperature to refine the grain structure and induce work hardening. It is reduced to its final thickness as per specifications, with precise control to ensure accuracy.

The processed aluminium strips are rolled into individual coils, neatly wound and ready for the next stage of production.

Using precisely engineered die sets, aluminium coils are fed into presses and punched into slugs of the required diameter. To ensure tight tolerances, die sets are regularly inspected and replaced as needed.

Slugs are heat-treated at optimal temperatures to restore ductility, refine the grain structure, and ensure they meet the mechanical requirements for our customers' downstream processes. The slugs are then subjected to a rumbling process if required by the customer for ideal surface finish.

A final inspection is performed to ensure the slugs meet all specifications. Slugs are carefully packed, labeled with their dimensions, and prepared for dispatch to the customer.
