According to statistics, the output value of the Italian plastics rubber processing machinery and mold manufacturing industry accounts for 16.5% of the total output value of the ten industries of the Machinery Manufacturing Alliance. At the same time, the main export destination of Italian plastic rubber processing machinery and mold products is still the EU, with an export value of 915 million. Its sales in 2011 increased by 11.1%, and its output increased from $3.6 billion in 2010 to $4 billion this year. At the same time, Italian exports increased by 19.3% over the same period last year and have grown to $2.4 billion.
Traction and cutting equipment
Small-diameter rigid PVC pipe (usually 12-75mm) for cable protection, supply, drainage and ventilation, mainly produced on multiple high-speed extrusion lines (above 20m/min), the economics of the production line Affected by downstream equipment. Downstream equipment not only has to match the production speed of the extruder, but also needs to be more adaptable than ever before, so it can be used in the production of various products.
SICA develops PT 75 and PT RS 110 combined traction and cutting machines for PVC-U and PP pipes
To achieve these goals, SICA (Alfonsine, RA, Italy) developed the PT75 and PTRS110 combined traction and cutting machines for PVC-U and PP pipes. Both models have a pull and a saw (2x1 mode) or two parallel pull and two saw (2x2 mode) modes. The PT75 can process high-speed extruded tubes with a diameter of 12-75mm and is equipped with a cut-off electric saw, which is swayed down by a cutting disc. The PTRS110 can process pipes up to 110mm in diameter and is equipped with a planetary saw with a probe that can follow a variety of elliptical tubes to ensure a very regular chamfer.
The traction unit has two tracks (which can also be configured for single belt traction). The upper track is tilted for pneumatic positioning and the lower track has a fixed height. The track has a chain with a high friction, low wear, neutral vulcanized rubber pad. Vector motorized belt drives (controlled by a closed loop system with speed sensor) ensure constant traction at different extrusion speeds.
The traction and cutting devices operate synchronously. However, the 2x2 mode can handle the speed phase fluctuations in the secondary extrusion process due to the independent cutting device, and can ensure the high-speed production of short pipes at high extrusion speed. For example, when the PT752x2 model is used to process tubes with a diameter of 12 mm at an extrusion speed of 30 m/min, the production speed can reach 3,600 tubes and 1 m per hour.
BAUSANO has developed a new machine that can cut 16 wood-plastic composite (WPC) profiles simultaneously.
