We all know that mandrels are musts and represent the industrial standards for manufacturing of FRP pipes. A good mandrel is the key of producing high quality pipes as bad mandrels will affect the quality of pipes and even make them difficult to demould. So it is important to choose quality mandrels. Trimming machine, also known as finishing machine, is designed for grinding FRP mould. Meanwhile, they are also ideal for trimming pipe surface, cutting the socket end of the pipe and grooving at the spigot end to let pipes be joined with each other. Our company has high capacity of machine manufacturing. Our trimming machine features high quality and excellent precision. Thus, they are capable to manufacture high quality moulds and FRP pipes.
