Guill Tool introduces Series 824, a co-extrusion crosshead designed for irrigation tubing with an emitter tool. Manufactured from stainless steel, this new crosshead features balanced flow design with spiral technology that improves flow characteristics at all extruder speeds. Dual feed ports provide concentric compound flow, while the splits flow from one extruder to feed the inside and outside layers via a manifold assembly. Series 824 is adaptable to all popular extruders on the market currentlyRead more
Guill Tool announces a new design for its high-production rotary models, both inline and crosshead style. A 2X increase in speed, with models running to 1000 RPM depending on the application, are now available in the Guill line of patented rotating tip & die designs. By rotating the tooling in relation to the material flow, a rotary head increases the wall strength of an extrusion, thereby allowing a thinner wall with less material and the corresponding cost savings for the user. Typical applications for rotary heads include medical and multi-lumen tubing plus various high-end extrusions with interlocking layer or multiple striping requirements.Read more
Part 1 of this contribution, published in the May 2021 edition of Rubber World, investigated a real manufacturer’s process that was set to produce medical tubing. It was found (through trials at the extruder, then through simulations) that the equipment available to the manufacturer was too large for the relatively low output that was required for this project, and consequently the polymer was degrading on the screw surface. It was ultimately determined through simulation that a smaller extruder, with a screw optimized for the low rate, would work better.Read more

Performance material usage is increasing in the manufacture of tires. These materials are composed of various additives with different properties that require a high level of expertise to maintain their properties throughout the production process and to deliver the desired, consistently high level of required quality. This is just one aspect that increases complexity in the manufacturing process. Market demands for more cost-effective products are also constantly increasing. Operating costs eserve special attention because process optimization is paramount on every manufacturer՚s agenda. Specialty chemicals group Evonik Industries and plant automation supplier Zeppelin Systems are working closely together to show how the use of innovative products and processes can both improve the performance properties of tires, while making their manufacture even more economical.Read more
Troester announces the development of the latest in its evolution of co-extrusion heads with an unrivaled range of CoEx heads for up to six compounds.Read more
The main advantage of the Auma operating principle over discontinuously operating platen presses consists of constant production conditions. The Auma ensures constant temperature, pressure and residence time values to avoid product quality variations, unevenness or undesired transition marks. That is reason enough why the Auma has firmly established itself in the market in the 0.5 to 20 mm thickness range.Read more
Wickert Maschinenbau has developed an extremely compact, setup-free multifunctional gripper for the handling of multilayer stacked or chaotically deposited components with layer separation.
The system is available with two different gripper types: A group of two to six fingers picks up work pieces and lifts them out of the transport container. As soon as one layer has been completely emptied, the separation sheet is removed by three close fitting, extendable vacuum suction elements on the gripper arm. The system is then able to access the next level of components.
MTA relied on ENGEL tie-bar-less technology right from the outset. The very first ENGEL machine delivered to MTA in Italy in 1996 was a tie-bar-less model from the ES series, the forerunner of today’s victory machines. There are now nearly 60 ENGEL machines in Codogno. MTA operates other ENGEL machines in Slovakia, Morocco and Brazil. The victory is the machine model of choice in all plants. From tiny plug-in fuses, connectors, fuse holders and radiator caps to complete power distribution units, MTA covers a very wide range of electrical and electronic products for the automotive, motorcycle, commercial vehicle and off-highway verhicle industries. Set-up work is correspondingly frequent, and this is where the tie-bar-less clamping unit of the victory machines proves to offer a clear-cut efficiency advantage. The short set-up times lead to a high utilization of the machinesRead more
The injection molding machine market is growing significantly and offers opportunities for various manufacturers. The APAC region constitutes approximately 61.0% of the world’s population, and the manufacturing and processing sectors are growing rapidly in the region. The APAC is the largest injection molding machine market with China being the major market which is expected to grow significantly. The rising disposable incomes and rising standards of living in emerging economies in the APAC are the major drivers for this marketRead more
