Our company has introduced the Spanish core-lift high-frequency vibration pipe making machine technology. This pipe making process combines the advantages of radial extrusion and core mold vibration, and makes up for the shortcomings of the two processes:

1. Combining the advantages of radial extrusion process, fast material feeding and fast forming, the production efficiency is higher than the core mold vibration process. The production capacity of the core-lift high-frequency vibration pipe making machine is slightly lower than the radial extrusion process, and the average production efficiency of a single pipe is 2 to 3 minutes/pipe.

2. Combining the advantages of the core mold vibration process, high-frequency vibration fully liquefies the dry hard concrete, and the density and strength are higher than the radial extrusion process; it fully meets the requirements of "GB/T11836-2009 Concrete and Reinforced Concrete Drainage Pipes" and "GB/T16752-2017 Concrete and Reinforced Concrete Drainage Pipe Test Methods".

3. It can produce reinforced concrete pipes with various interface types with an inner diameter of 300 to 1500*2-3 meters: flat mouth, socket, steel socket, flexible tongue and groove, etc.

4. The dry hard concrete is fully liquefied and compacted by high-frequency vibration molding, without moving the pipe concrete, so that the pipe body's anti-seepage level is further improved, and steam curing is unnecessary. The strength can reach more than 80% after 3 to 4 days of natural curing, which reduces the company's production costs.
