About HLM
Leuthold Mechanik AG (HLM) is a Swiss mechanical engineering company founded in 1974 and headquartered in Einsiedeln. From the small mechanical workshop of its founding years, the company has grown into an enterprise with 175 employees and worldwide connections. HLM designs and manufactures custom special machines, tools and testing systems, specializing in systems for producing thin-walled aluminium packaging. Its core competence encompasses metalworking with turning, milling/drilling, grinding and EDM at machining accuracies below 0,002 mm, complemented by toolmaking, contract manufacturing and series production in 3-shift operation. In its own Competence Center, systems can be tested in a monitored test environment before integration at the customer's site. Customers come from the packaging, food, automotive, aerospace and medical technology industries. On 20'000 m² of operating space, development, manufacturing, assembly, installation and training are offered from a single source.

Materials & Processes
Aluminium (coated packaging foil)
Coated aluminium foils are punched and deep-drawn into heat-sealable trays and containers for direct food contact.
Metal in general
Metalworking has always been HLM's core competence, among other things for tools, machine components and testing systems.
Turning
Precision turning of metal components with accuracies below 0,002 mm.
Milling / Drilling
Milling and drilling of metal components with tolerances below 2 µm.
Grinding
Grinding processes to achieve the highest surface and dimensional accuracy.
EDM (Electrical Discharge Machining)
EDM processes for complex contours in tools and metal components.
