Parallel twin screw extruders are fastened together at their central shaft with a number of cross threads on both sides. They are generally used for fastening plastic fabrication work to a hard surface such as metal or wooden block. They are available in different sizes and threading pattern according to the application used. Their design makes them ideal for fastening materials of different dimensions. For small jobs such as screwing a few screws into a frame to fasten them, a pair of Parallel Twin Screws is sufficient.
According to the nature of the material used, the perpendicular axis of a parallel twin screw extruder is parallel or conical, while the cross threads of a conical twin screw extruder are flat. This variation enables the manufacturers to use various sizes of screws in their products, depending on the required application. Thus, a flatbed scanner or a printing press will require different sized screws than those needed for assembling a roof deck or a cabinet. Similarly, if you are looking to install a fan or an outdoor lighting fixture, the diameter of your screws should be slightly larger than that of the screws used for assembling a cabinet.
In case of a conical twin cutout, the number of screws required will be dependent on the center distance between the holes spaced apart by a corresponding number of millimeters. With this calculation, you will get the right number of parallel cuts. Likewise, with the parallel version, a smaller number of parallel cuts are possible for the same number of holes. If your product involves intricate drilling, then it is better to opt for a conical model.
A conical twin screw also has a variety of advantages, but these are mostly found when one or both sides are small. The design is possible with a small hole at the small end and a larger hole at the large end. This way, the fastener can easily accommodate any kind of joint that is being worked on, thanks to the small and large end points. The small end holes can even be drilled for pilot light fixtures.
A further advantage of using conical twin-screw extruders is that the screws can have either small flat contact pins or large contact pins, depending on the joint being worked on. This way, a user can attach or detach any joint quickly and easily. If you want to do some small projects that require only a few joints, then you can opt for the pin style. But if you are looking to do large projects like those that involve assembly of large structures, then you should go for the screw style.
Parallel twin-screw exponents include contractors, architects and fabricators because of their many advantages over screw-type dies. They are also preferred by users who want to have a wider range of uses for their hardware. In addition to this, these types of dies can also reduce the manufacturing cost because they are made of less expensive materials than those used in standard dies. Granulating line, CNC line and other die services can also be done easily with these screws.
