Manufacturing and processing of rubber rollers, system rollers, turned and milled parts with core production, rubber coating and coating
Maier Walzen GmbH
WaldkraiburgNew on Amplifa
Family company for rollers and precision parts
Maier Walzen GmbH is a medium-sized family company in Waldkraiburg that has been manufacturing rubber rollers, ready-to-install system rollers as well as turned and milled parts since 1997. Production spans three areas: In core production, roller cores and plain turned parts are manufactured from steel, stainless steel and aluminium using sawing, CNC machining (turning, milling, drilling, grooving, knurling), welding and bonding; roller cores up to 2500 mm in length and 250 mm in diameter are possible. In rubber coating, rollers and rubber sleeves are fully coated in the company's own production facilities. Complete manufacturing delivers ready-to-install system rollers such as pressure and tension rollers, deflector rollers, conveyor rollers, laminating rollers or contact rollers. In addition, surface coatings (including anodizing, galvanizing, hard chrome plating) as well as roller repairs, such as journal repairs by build-up welding, are offered. Customers include industries such as mechanical engineering, the printing industry, film production and finishing, the wood and furniture industry, the textile and food industries, conveyor technology and automation technology. With around 40 to 42 employees at one site, the company covers all process steps in-house.

Additional services
Quality
The core production process includes an intermediate inspection (testing) to maintain quality standards; during alignment, the smallest runout tolerances are observed. All process steps take place in the company's own production halls in-house.
