La parte principal del tornillo de pasador es un tornillo común, y el pasador de bloqueo se puede fijar en la ranura de la sección de fusión o sección de medición del tornillo, o en la superficie cilíndrica lisa al final de la sección de medición sin ranura de tornillo. Los pasadores de bloqueo están dispuestos de cierta manera con densidad y cantidad variables. Los pasadores de bloqueo cilíndricos se ensamblan en los orificios del tornillo, mientras que los pasadores de bloqueo cuadrados o en forma de diamante se fresan directamente sobre el tornillo. Si estos pasadores de bloqueo se colocan en la zona de fusión, pueden triturar la cama sólida, interrumpir el flujo de dos fases y mezclar las fases sólida y líquida, aumentando el área de contacto entre la fase sólida fragmentada y la materia fundida, promoviendo la fusión. Si los pasadores de bloqueo se colocan en la zona de transporte de fusión, su función principal es dividir el flujo de material, aumentar la interfaz, cambiar la dirección del flujo de material y reorganizar el haz de flujo. Al dividir y fusionar repetidamente y cambiar la dirección del flujo, se pueden homogeneizar los componentes y la temperatura del material fundido.La sección de mezcla es una estructura ranurada que se abre hacia adentro, colocada en el extremo de la sección de homogeneización de tornillo común, y su diámetro exterior es igual al diámetro exterior del tornillo. Las ranuras se dividen en varias grupos y la zona de convergencia del
