PROCESSING MACHINERY
NEWS New line from Binova
The possibility to carry out two processing phases in one offers all-round benefits, from greater competitiveness to the improved quality of the final product
Two in one The new BiReC line developed by Binova (hall A6, stand 6207 at Fakuma 2017) is able to execute in a single stage what is normally done in two: recycling and compounding. This technology can process post-consumer polyolefins in the form of grinded sheet coming from a washing line and the resulting pellet guarantees a high-quality final product. Despite the origin, by using dual automatic filtration, it is possible to guarantee to the end user the production of films with thicknesses of about 20 microns. The line in question uses a corotating twin-screw extruder which can reach a production between 1400 and 1800 kilograms per hour,
depending on the material introduced. The plant is able to compound post industrial waste with high residual moisture (up to 8%) with particular blends of pellets. The presence of a high-vacuum degassing system distributed over almost the entire length of the extruder barrel (3 vacuum degassing flues and 1 atmospheric exhaust flue) allows the granulation of
Injection machine from Presma
Single-station moulding machine for large parts A 1,600-ton injection moulding machine was recently supplied by Presma to a major Italian processor. This machine stands out thanks to its ability of co-injecting shots up to 20 kg for the production of sandwich structures. Designed as an automatic moulding cell, the press is worth 1 million euros and will allow the processor to optimize the production of large
bi-component parts both foamed and solid which are now moulded on Presma multi-station rotary machines. This is the first medium tonnage single-station injection moulding press equipped with the “BIC� injection unit, patented in 1981 and since then offered by the Italian manufacturer for the production of thick section parts. www.presma.it The special BIC injection unit is supplied for injection moulding of highthickness articles

highly printed films (up to 80% of printed area). The mixing of the raw materials, which occurs directly in the machine, leads to a perfectly homogeneous material, able to improve the quality of the final product. The dosing system of the various materials can be both gravimetric and volumetric. A new gravimetric control system for grinded film, even with a bulk density of around 0.05 kg/dm3, guarantees the exact percentage of grinded sheet to be fed to the extruder. The production of this technology is entirely made in Italy, with particular attention to the quality of all the components. Being able to perform this process in a single step makes BiReC lines very competitive. In addition to the reduced handling of the materials inside the factory, another very important aspect is the proven reduction in energy consumption compared to other plants on the market today: for LDPE-based materials, consumption will not be higher than 0.26-0.27 kW/kg, whereas for PP-, PSor HIPS-based materials, consumption will be around 0.22-0.23 kW/kg (excluding the cooling of the process water). Compared to a traditional line with a single-screw, the energy saving amounts to almost 30%, thanks to the corotating twin screw which has a higher degree of optimization. This plant has been designed to meet the specific needs of a customer who wanted to obtain the same product with higher yields, but it is perfectly suited to the requirements of the entire market. www.binovapm.it MACPLAS INTERNATIONAL AT FAKUMA 2017
