Company
Lindner Armaturen GmbH in Chemnitz produces valves, fittings, hoses and technical components for the plumbing and heating sector, HVAC/building services, gastronomy and laboratory applications, the aviation and marine industries, and network technology. Manufacturing encompasses CNC turning and CNC milling including 5-axis and freeform machining, forming, casting and pressing, plastic injection moulding, soldering, flow drilling, assembly into complete assemblies, and in-house surface technology (nickel plating, tin plating, chrome plating, PVD/powder coating, painting, laminating, laser marking). Materials include various brass alloys, gunmetal, copper, stainless steel, plastics (POM, ABS/PC, glass-fibre-reinforced PA) and the mineral material VARICOR. Since 2019, production has been running at the expanded Rottluff plant (10,000 m²); hoses are manufactured in Rabenstein, and since 2025 steel has also been braided there; a dedicated Automation Technology unit develops manufacturing automation. Quality assurance is carried out company-wide using a CAQ system in accordance with DIN EN ISO 9001:2015.

Materials & Processes
Brass (various alloys)
Traditional material for valve bodies, fittings and valve blocks in drinking water and heating applications.
Gunmetal
Casting material for valve and fitting parts in the plumbing and heating sector.
Copper
Processed by cutting to length, bending, soldering and flow drilling, e.g. for manifold bars and bends.
Stainless Steel
Machining, bending and polishing for nipples, blanking plugs and garden valves.
POM (Polyoxymethylene)
Lightweight, drinking-water-suitable plastic for injection-moulded and machined valve components.
ABS / PC (Polycarbonate)
Injection moulding for caps, levers and operating parts, printable with customer logo.
PA (glass-fibre-reinforced polyamide)
Corrosion-resistant hose carrier material for connectors with compression fitting.
Mineral Material VARICOR
Material for custom washbasins and valve parts with seamless, hygienic joints.
