Factors affecting the torque of the screw:
1.Screw diameter: The larger the diameter of the screw, the greater the required electric torque. Because the larger the diameter of the screw, it usually means eating the inner side of the deeper plastic.
2.Screw length: The longer the length of the screw, the greater the required electric torque. The electric torque is basically proportional to the contact area between the screw and the plastic. As the screw locks into the screw hole, the more screw area is in contact with the plastic.
3. Screw pitch: The larger the screw pitch, the greater the required electric torque. This seems to be somewhat inconsistent with the contact area above, but this is because the screw is also rotated one turn, and the screw with a relatively large screw pitch is deeper than the pitch, so a relatively large torque is required. Just like a gear with the same diameter and different gear numbers, turning the same individual gear, the more the number of gears, the more labor-saving.
4. Screw shape: sharp-tailed, triangular. Torque is not much related to the shape of the end of the screw, but the shape of the different end of the screw usually represents a different thread design. As far as experience is concerned, the screw with a pointed tail has a shallower thread and the required electric torque is smaller.
5.Screw hole diameter: The smaller the diameter of the screw hole, the greater the required electric torque.
6. Screw hole draft angle: The larger the demolding angle of the screw hole, the greater the torque needs to be. This is because the smaller the hole diameter toward the bottom of the screw hole. Also worth noting is the subsequent screw boss draft angle, which directly affects the thickness of the screw column.
7.Screw hole chamfer: The function of the bevel is to help the screw stand on the screw hole, so that the operator does not easily slip to the side when the screw is locked. However, if the slope is too large or too deep, although the required electric torque may be smaller, the remaining area of ​​the plastic screw post and the screw will be less, which may reduce the locking force of the screw.
8. Plastic resin material: The harder the plastic material (such as reinforce or plastic with glass fiber), the greater the electrical torque required.
