Understanding the Design and Manufacturing of Plastic Threaded Rods
There has always been a debate on what type of threaded rod would work well with heavy equipment. Earlier, metal rods were chosen, with the belief that only they had the durability to withstand the weight of heavy equipment. However, due to many advancements in technology, plastic threaded rods are also becoming a popular choice. Plastic threaded rods are known for their precise design, wide range of materials, non-corrosive properties, and immense strength. Due to these reasons, many heavy equipment manufacturers are going in for plastic threaded rods.
Factors Considered to Design and Manufacture Plastic Threaded Rods
Plastic threaded rods are mainly differentiated by three factors. The points below discuss them in detail.
- Size: The size of a threaded rod is a huge factor, as the rod has to meet certain specifications for heavy machinery. The smallest size of a plastic threaded rod can be about ????. Larger sizes can start from 1 ????, and extend beyond 3 inches. The size of the rod refers to the length, and not width.
- Materials: There are a few basic materials that are used to create plastic rods. Nylon is the most popular option, with glass reinforced nylon coming at a close second. Other material options can include acetal, polypropylene, polyethylene, PVDF, and polycarbonate.
- Thread Direction: The thread direction can be right handed or left handed. The right hand thread is more common. Right handed threads move in a clockwise direction, while left handed threading moves in an anti-clockwise direction. Right handed threads are usually used for fasteners. Left handed threads are used with engines and automobile parts.
Plastic Rod Manufacturing Processes
The main procedures used to manufacture plastic threaded rods are plastic stamping and CNC machining. Plastic stamping involves creating the rods from extruded plastic sheets and a punch press with stamping dies. CNC Machining is used to cut away unwanted material from a pre-existing raw material. Both these methods allow for the creation of standard and custom plastic rods. In the next post, we will discuss the procedure to thread the plastic rods.
