DOPAG · INJECTION MOLDING · 03 We understand the challenge at hand Stability and reliability in continuous use Secure production processes in the case of high loads are a key requirement for your business success. Thanks to robust technology, we ensure that your production runs reliably – with even shorter setup times. The continuously growing demand for silicone products is due to the special properties of the material. For example, it can be reformed even after it has been processed. As high elasticity is needed for many products, this key distinguishing feature compared to other materials...

04 • DOPAG • INJECTION MOLDING silcomix The silcomix is a compactly designed, electrically driven piston pump, metering and mixing system. It is used for continuously processing medium to high-viscosity, silicone-based media with a mixing ratio of 100:100. Metering is carried out directly from the original containers with a size of 20 or 200 l.

DOPAG · INJECTION MOLDING · 07 Revolutionised LSR mixing unit Previously, setup work on LSR mixing units was a complicated process that took a long time. It was a job that required tools and sometimes even needed the involvement of several workers. Thanks to the new mixing unit for the silcomix LSR metering system, this has changed fundamentally. The new design is unique on the market and simplifies operation while ensuring shorter setup times and greater system availability. Maintenance time and intervals can be reduced by up to 75 per cent. The low-viscosity silicones increasingly being used...

DOPAG · INJECTION MOLDING · 09 Precise SWIPSYNC Synchronous switching of servo-electrically driven piston pumps for precise adherence to mixing ratio ensures uniform drum drainage of the A and B components. The collapse in pressure flow, and thus also volume flow, is considerably reduced through a special control of the servo drives, with the time also significantly shortened. Pressure / volume flow The servo-electrical drive enables synchronous switching of the piston metering pumps, regardless of the current position of the respective pump piston (switching point synchronisation). This prevents...

Our silcomix is used in many different industries and applications Automotive industry e.g. seals on car keys, general connector seals, valves, membranes, LED lens optics, cable harness seals Electrical engineering e.g. coatings, various seals for smartphones, watch straps, seals for ‘brown goods’ Household and kitchen e.g. baking moulds, kitchen utensils, various seals for perfume bottles Aviation and aerospace industries e.g. valves, membranes, cable harness seal

Baby care e.g. soothers and bottle teats, toys, teething rings, toothbrush handles Medical technology e.g. respirators and syringes, nose pads and temples for glasses, pumps for nose drops, surgical replacement parts (e.g. kidney repair) Sanitary technology e.g. shower heads, shower frame seals (by the yard/metre), valves (fittings)
