1. Split-type mold (opening and closing type)
Structural features: The mold is divided into "upper mold" and "lower mold", connected by hinges or guide rails, which can be opened and closed. When pressing, the pipe material / pipe fittings are placed in the mold cavity, and then pressure is applied after closing.
Core application: ① "Fixed pipes" that have been laid (such as short pipes extending from the wall); ② Large-diameter pipe materials (DN63 and above), as the overall mold is heavy, the split type is easier to operate.
Advantages: ① No need to insert the pipe from one end into the mold, suitable for "mid-section connection"; ② The mold is easy to disassemble and assemble, facilitating the replacement of different specifications; ③ Low maintenance cost, individual mold pieces can be replaced separately when damaged.

2. Integrated mold (cylinder type)
Structural features: The mold is in the form of an "integral cylinder", and the pipe material needs to be inserted from one end of the mold, and then the other end is pushed out to connect with the pipe fitting, and then pressed.
Core application: ① "Straight pipe connections" that have not been laid (such as factory-premade pipes); ② Small-diameter pipe materials (DN16-DN50), with high press-fitting efficiency.
Advantages: ① The force is more evenly distributed during pressing, resulting in high connection accuracy; ② The mold has good sealing performance, preventing the pipe material from shifting during pressing; ③ Small in size and light in weight, suitable for handheld electric pipe pressers.
