Nuestra compañía no solo tiene el logro notable sobre la producción de tornillos y barriles bimetálicos normales, sino que también hemos investigado profundamente en el barril y el tornillo para el plástico de ingeniería especial, por ahora gran parte de los plásticos de ingeniería agregan el calcio, la caolín, la arcilla roja, sílice o agregar fibra de vidrio, fibra de carbono, fibra de boro y plástico sin halógeno para que el plástico original sea mucho mejor para adaptar los productos de plástico específicos. Por otro lado, puede hacer que el tornillo y el cañón se desgaste rápidamente, para resolver Este problema, hemos inventado una especie de polvo de aleación especial, cuyo ingrediente contiene 25% ~ 50% WC de carburo de tungsteno. Hace que la vida útil de los tornillos y el barril sea mucho más más largo que los otros tipos de tornillos y barriles bimetálicos.
