High Functionality, Reduced Downtime

In the Iron and Steel industry, there are pronounced demands on people, materials and technology. TaiWan MKC Sealing Technologies provides compact sealing systems that seal reliably – even in extremely harsh conditions – to meet these challenges, as well as high operating life requirements, including temperature, stroke, speed, pressure, friction, duty cycle, radial force and lubricants.

Our seals contribute to:

• Better output – benefitting both quantity and quality
• Lower costs
• Less downtime
• Improved performance through longer maintenance cycles

• Industrial Machine Tools, Seals for Injection Molding Machines and Presses

  Keeping Time With the Machine

  Strong forces with moderate movements, extremely variable forward and return stroke speeds, extremely short strokes at a high number of cycles, in some cases under a continual load or with fast load changes – the operating conditions for seals in hydraulic cylinders for industrial presses and injection molding machines are diverse and always challenging. This requires technical excellence. The highest level of reliability is in demand. So are stick-slip-free performance and low operating costs.

• Patented Pressure Relief

  One ingenious solution from TaiWan MKC Sealing Technologies is the patented pressure-relief function. Rapid forward strokes in combination with slow return strokes can build up considerable pressure in the cylinder and lead to a failure of the sealing system due to extrusion. In these cases, a small borehole in the primary seal facilitates the return flow of fluid into the working chamber. This creates a pressure balance – small borehole, great effect!

• Maximum Efficiency From the Best Possible Combination

  Rod Seals from TaiWan MKC Sealing Technologies are used in state-of-the-art sealing systems for cylinders of all kinds. They are specially adapted to the respective conditions of use and tasks while meeting customers’ high expectations for maximum reliability, service life and functionality. State-of-the-art hydraulic rod sealing systems generally consist of several individual seals (see example in Fig. 1). The so-called primary seal faces the cylinder’s working space and reliably seals against the high operating pressure within the cylinder.

  The secondary Rod Seal fitted behind it takes over the main sealing function. It is above all designed to reduce the residual oil film on the rod to a minimum during its extension. Seals constructed of polyurethane are preferably used for this task. With their defined sealing lip, they ensure the finely tuned wiping of the medium, guaranteeing the leak tightness of the cylinder toward the exterior.
