What Makes Hongda Rollers Top Quality
Unique design of roller body, two sealed covers in ends are out of
tube, which effectively prevents water in.
labyrinthine dust-proof design sets layers of defence, which
prevents the dust from entering the heart of roller -- bearing.
More components of the roller are treated by special technique,
less maintenance is needed during working processing.
After analysis of mechanical properties and physical properties of
various plastics, and after practice and test, Hongda finally
chooses NYLON, PP(Polypropylene), HMWPE (High Molecular Weight
Polyethylene) as the main material to produce the parts of roller
by modification or single way. The parts' work are aligned well in
variety of environments.
Craftsman's spirit, making every detail perfect from material
selection to processing.
Customize plastic(nylon) roller fitting in various adverse
circumstances according to customer's requirement.
