Balines de Plástico

Los balines de plástico se fabrican con resinas poliméricas en tamaños desde 1mm hasta 180 mm. Los balines de plástico son una opción rentable para los balines de acero en algunas aplicaciones. Se pueden utilizar como agitadores dentro de latas de aerosol, válvulas, equipos médicos, baleros, una amplia variedad de aplicaciones. Tolerancias hasta +/-0,0005" (+/-0,0125mm). Las superficies pueden fabricarse a medida desde acabados rugosos hasta acabados altamente pulidos.
