Abstract: Disclosed are a method, an extruder and an injection molding machine for manufacturing a clamping ring, solving problems that products produced by an extrusion method needs to be processed in two steps. The key point of technical solutions lie in a molding step of acting on a pipe member in a plastic melt state via a molding die set, to form a clamping ring from the pipe member; an injection mold injects plastic materials having memory properties through an injection gate to form a pipe member in the molding cavity, the pipe member comprises a clamping ring and a sealing film provided on one end of the clamping ring, the hydraulic mechanism drives a molding cutter to cut out a joint of the sealing film and the clamping ring in a plastic melt state, thereby a limit end is formed at one end of the clamping ring.

Abstract: This application provides a clamp and a method for using the same. The clamp includes a clamping band which is wound to form a clamp body defining an accommodating area. The clamp body is provided with a tightening lug. The clamp body includes an overlapping portion and a single layer portion which is provided with a positioning member. The positioning member is connected to the clamp body such that the positioning member is slidable toward an inner side of the accommodating area with one end extending into the accommodating area. An inner wall of the clamp body is gradually approaching an outer wall of a pipe with the tightening of the clamp, the positioning member moves outward relative to the clamp body until the inner wall of the clamp body rests against the outer wall of the pipe, and then the positioning member falls off from the clamp body.

Abstract: A positioning error prevention hoop including a hoop body curled to form a sleeving area. After a limiting member is connected on the hoop body, a limiting block of the limiting member abuts against an end of a pipe to control a distance between the hoop body and an end surface of the pipe, such that the hoop body may be secured on an appropriate position. A fastening component is clamped to tighten the hoop body on the pipe. As such, the hoop body will not tend to fall off from the pipe and may also squeeze the pipe and fit it with a connecting piece to form sealing.
