The bauku extrusion technology Ltd., short name "bauku" is producing extrusion lines for the manufacturing of plastic pipes since the year 1956. Our experience gained in selling these systems over decades, enables us to manufacture customized machinery designs for pipe projects all over the globe.So what is the extrusion process of the bauku machine?What bauku machines can our company provide?

What is the extrusion process of the bauku machine?

P:High ring stiffness profile pipes

The first extruded layer of the pipe is always a solid wall profile, followed with a second layer of a hollow round chamber. The round profile is formed with a core tube (see c-series machinery), which is surrounded with PE100 or modern PP inside the extruder die head. If a manhole shaft is produced, a third layer will add another solid wall profile.

The extrusion lines can be equipped with one, two or three winding stations to increase the efficiency and production capacity of the machinery. Each winding station is able to handle all sizes of mandrels within the designed diameter range. This technology is also ideal for small quantities of one order (one pipe size and profile), as you can produce different diameters and profiles on each winding station, one after another.

C:Core tube as precursor for the p-series

The profilline p-series needs a core tube as precursor for the profile pipe (besides the resin, PE or PP). The customer has the choice to buy such a core tube from his local market (it is normally available for the electric installation in houses) or to get a profilline c-series to manufacture the core tube by himself.

The core tube needs a good flexibility combined with a high ring stiffness, but most of all it needs a high thermal stability. The tube is covered in the die head of the p-series later with 200°C hot PE or PP and it has to keep its round form until the surrounding hot material cools down.

The necessary temperature resistance is guaranteed by a special profile design of the core tube and the modern PP which we use as a resin for the c-series machine. 

The bauku profilline pipe(c-series) is designed for a highly flexible production. The machinery will produce different sizes of core tubes, tailor made for the p-series extrusion line。

The machinery is equipped with a double coil station in order to allow a continuous production. The coils are put on stock as a buffer and are used later at the p-series just in time. 

What bauku machines can our company provide?

Our company (Qingdao Yongke) has more types of bauku machines. Mainly: carat tube (high-density polyethylene structural wall hot wound pipe machine), carat tube production line, PP seamless winding tank production line. In addition, there are also bauku machines such as profile pipe, Bauku profilline pipe, Spirolite pipe, and wound pipe machine.

Welcome to our company to buy bauku machines. We will provide you with the best products and services. I wish you a happy life and good health.
