Co-injection molding is one technology of interest for those designing hydraulic systems for o!-highway use. This allows two polymers to be combined in a single operation to create multiple functions in onecomponent. A good example is an elastomeric material that acts as a seal and a scraper combined with a stronger thermoplastic material that acts as a bushing or guide ring. This component would be anideal molded rod end in a hydraulic cylinder used in the excavator bucket of an o!-highway vehicle, for instance.
Reducing Risk with Geometric Transition Extrusion
By Dan Sanchez, Product Manager at Trelleborg Healthcare & Medical
In an effort to design smaller, more intricate and complicated medical devices without running afoul of increasingly stringent national and international regulations, many designers are looking to geometric transition extrusions manufactured of high consistency rubber (HCR) silicone. This process reduces total cost of ownership for the original equipment manufacturer while improving part quality and greatly enhancing the types of devices being sought by healthcare medproviders.

THE TRANSITION FROM METAL to composite is one of the most recent significant changes in manufacturing.
The former material is isotropic, exhibiting uniform stretching and bending behavior in all directions. By contrast,composites are anisotropic. They stretch, bend and break differently in different directions, based on how the fibers are woven together and how the laminates are bonded. This fundamental difference throws many traditional simulation protocols and practices into chaos.

Seals used in offshore rig tensioner cylinders must meet the same rigorous lifecycles as the cylinders themselves. Because offshore environments are harsh and installation and maintenance can be difficult, tensioner cylinders must have a 20-year life. That was why, more than 20 years ago, Trelleborg Sealing Solutions conducted research, determining that its seals could last this necessary lifecycle.
Trelleborg's 2K technology enhances options for medical device manufacturers

When it comes to the safety and efficiency of medical devices, lives could literally be on the line.
Whether it's a wearable pump for insulin or implantable delivery devices, proper dose regulation and biocompatibility are crucial.
Trelleborg Sealing Solutions has developed a unique engineered seal– specifically for use within Central Tire Inflation systems. Turcon® Roto L is the first ever active seal, engineered to only provide sealing when required. Eliminating friction and torque, this extends the seal life of axle systems and can significantly reduce fuel consumption for vehicle operators.
Modern machinery, equipment and motors fitted with hydraulic cylinders are becoming more powerful, which means that the hydraulic systems therein are increasingly subject to higher operating pressures and temperatures.

The chemical compatibility of a seal with the fluids in a system is critical to obtaining a reliable, long-lasting seal. Here are some considerations for choosing the right material for a given chemical sealing application.
New developments in sealing technology require the use of advanced design techniques, and a complete solution requires pre-processing, solution and post-processing for effective nonlinear Finite Element Analysis.
Finite Element Analysis (FEA) software is used to create computer-generated models of materials or design components. These are then subjected virtually to mechanical, thermal or other stresses so that engineers can predict material and product performance.
The Research and Markets Institute (researchandmarkets.com) projects the global household appliances industry to reach an estimated value of US$ 324.2 billion by 2019. Amongst the major drivers are growing affluence of the middle-class population in emerging markets, higher disposable incomes, and more per capita spent on lifestyle products in increasingly urbanized environments.
With global engineering and production facilities, state of-the-art cleanrooms and advanced automated processes, Trelleborg Sealing Solutions already offers its medical device, biotech and pharmaceutical customers specialized custom molded solutions that enhance their product offerings.
As the world attempts to reduce its dependence on fossil fuels, biofuels are now a reality. Brazil and the U.S. were early adopters of this alternative fuel for transportation but now its use is expanding in Europe, with Germany, France and Spain leading the way.
Perfluoroelastomer (FFKM) elastomers offer exceptional thermal stability, outstanding long-term compression set and almost universal chemical compatibility – delivering long life in the most aggressive of media, including hydrocarbon and aqueous media, common within oilfield applications.
