Wiper arms


04ramionaengOf the entire range of MOTGUM products, wiper arms prove to be most durable and corrosion-resistant. In the rigorous salt chamber testing process, they achieve a result of well above 480 hours (ASTM B – 117 criteria). Compact, all-metal construction of arms as well as highest quality raw used for their production provide perfect stiffness, which allows for reliable wiper operation regardless of temperature conditions.

Metal parts:
– made of strain-hardened steel sheets with anti-corrosion aluzinc coating above 25ľm,
– rolled, zinc-coated steel bars of improved stiffness (C45 material), with calibrated arm tip for easy and reliable wiper assembly,
– arm heads made of aluminum or aluzinc,
– sleeves and rivets manufactured on precision turning lathes, made of certified, corrosion-resistant raw materials.
– specially designed, purpose-manufactured springs and joints (CII material), selected to comply with most rigorous dynamic requirements. These provide prefect pressure of wiper blade against the windscreen in all conditions.

Head cover – made of PBT (Polybutylene Terephthalate) – a plastic resin of exceptional mechanical properties and high endurance to atmospheric factors.

Coating – paint: polyester resin of high resistance to UV radiation and atmospheric factors (salts, acids, exhaust pollution).

MOTGUM wiper arms comply with FIAT 9.93606 and DAEWOO EDS – T – 3409 norms regarding functionality and material properties. The manufacturing process is constantly monitored with the help of statistical methods. Additionally, wiper arms are periodically tested to achieve constant, highest-quality level.
