New model of laboratory extruders24.03.2014
The results of the research conducted by Zamak Mercator, especially in the innovative design and innovative performance of laboratory extruders is a response to market demand from consumers who expect better technical parameters of the equipment with regard, in particular, to the diameter of the screw, torque and power of an extruder - decisive criteria for high precision, optimizing processes and greater possibilities in terms of conducting tests on these devices in the plastic materials group characteristic for their high resistance during the extrusion process.
One such solution is the laboratory extruder EHP - 2 X Ø16.
Based on Zamak Mercator R&D results the company developed a new model of laboratory extruders for the extrusion of difficult to process polymers. The developed screw drive enables to obtain the highest torques available on the market even at low speeds. The innovative gearbox enables the torque amounting to 2 x 27 Nm for a twin-screw extruder with screw diameter of 16 mm EHP2 x 16 Sline. The drive system allows the extrusion of the materials in a wider range of viscosity and flow and controlled extrusion at extremely low speeds.
Advantages of the new solution: Strength optimization of the gears, and increasing the maximum rotational speed of the screws allow the process of intensive mixing and uniform distribution of reinforcing phase in the whole volume of the extruded profile. The newly developed configuration of cylinder provides for uniform distribution and stability of temperatures, making it possible to obtain better physical-chemical properties of plastic materials, sensitive to small differences of temperature during processing. Uniform heating of the cylinder to 250 °C and full readiness for the extrusion process is now possible in less than 5 minutes. The use of an innovative system of cylinder thermizing also increased cooling efficiency thereby giving better control and greater possibilities of processing plastic materials. Cooling the cylinder after performed process down to 50°C in less than 10 minutes. In addition, the extruder was optimized in terms of accuracy and the number of recorded measurements, thereby obtaining better properties on extruded polymers. Innovation of the company: Introducing a new series of laboratory extruders of globally unprecedented technical parameters, significantly increased the technological potential of the company, as well as the ability to offer innovative products with a high degree of technological advancement to the market. The new model of the extruder described in the article, called Sline, is yet another highly advanced laboratory machine manufactured in Poland. It is worth mentioning that in 2012 Zamak Mercator developed the smallest available on the market switchable gear for twin-screw extruders with a screw diameters of 16, 20, 24 mm - IQ model, enabling work in two modes synchronous and non-synchronous. Zamak Mercator laboratory extruders may operate as the primary device in a laboratory line for the production of, among others: granulate, re-granulate, micro-cables, foils, polymeric fibers, as well as, fabrics manufactured by means of the melt-blown method. Apart from the described devices, the company manufactures many other innovative machines and lines both, laboratory and industrial for processing of plastic materials and rubber. More detailed product information is available from the sales consultants and technical specialists.
