Oil dispensing in perfection
Oil dispensing in perfection: DOPAG has developed the lubriLine product family for metering applications in the automotive industry. It meets all specific requirements for highly automated greasing and oiling.
High repetition rates, short cycles and narrowly defined tolerances for the applied quantities determine the metering processes in the automotive industry. Thus, a precise and reliable metering is indispensable. Therefore, DOPAG has developed the lubriLine especially for the application of lubricants in the automotive industry.
Modular structured drum pumps
The next generation drum pumps P80 and P200 form the basis of the lubriLine system concept. DOPAG has designed them especially for grease applications by adopting double-acting ball valve pumps or chop check piston pumps. They deliver greases and oils up to NLGI class 3 from the original containers without any problems. Furthermore, the installed follower plate has the function to fill the pump continuously and neatly with the material to be delivered by applying an optimum surface pressure. The sealing of the plate towards the atmosphere prevents the intake of air and the formation of bubbles in the grease. The elevators are available in two basic configurations, P80 and P200. The modular structure of the drum pumps enables an individual configuration and optimum layout for each application.
The right valve for each application
The basic configuration of the metering system, consisting of pump, material pressure regulator and dispensing valve or metering valve, can be complemented with other components such as a control unit or a volume counter. Furthermore, the DOPAG lubriLine offers the most suitable valve for each application. DOPAG needle metering valves or chamber metering valves provide a reliable solution for contact greasing in case of applications with short cycle times and the need of an exactly reproducible quantity. The DOPAG high-speed valve allows for a contactless material application over a distance of up to 120mm. It can also be used efficiently for hard-to-reach places.
For the contactless greasing, DOPAG has complemented the product family with a shot valve as well as a spray valve. Within a very short time, the shot valve can apply an extremely high number of shots – up to 200 cycles per second – using the least amount of material possible. Thanks to various extensions and attachments, the two new valve types can cover various application angles without any problem – they are best suited for the greasing of hard-to-reach spaces such as components with undercuts.
Hard-to-reach places, various inclination angles or high shot rates – oil dispensing is an easy task with the components of the DOPAG lubriLine. Due to the high-precision and reproducible metering application, the DOPAG metering systems meet the high manufacturing standards of the automotive industry.

DOPAG presents new LSR pump technology at Fakuma trade fair 2017
Products from liquid silicone rubber (LSR) are being used in different industries: from automotive production to household appliances and medical technology. The highest degree of safety and maximum reliability are crucial factors - not only when using silicone products but in the production of silicone products. This was a decisive factor for DOPAG when developing the new LSR pump silcomix.
Live application at Fakuma trade fair 2017
DOPAG will introduce the innovative LSR technology for the first time at the Fakuma trade fair 2017, the leading international trade fair for plastics processing in Friedrichshafen, Germany. From 17 to 21 October, the new silcomix LSR-pump will be on display at the DOPAG booth. The application is realized by DOPAG together with the injection molding machine manufacturer Wittmann Battenfeld as well as the material manufacturer Wacker Chemie and the mold manufacturer EMDE. Visitors could view the processing of LSR materials with the new LSR pump live in an application. DOPAG experts are available for questions and advice. Another live production of LSR products with the new silcomix can also be visited at the booth of the injection molding machine manufacturer KraussMaffei. They show how reliable the DOPAG LSR pump operates in the production chain.
The new silcomix type PE200/20 offers reliable production in all areas thanks to a wide range of applications. The silcomix processes virtually all of the LSR materials available on the market – whether they are of extremely low, medium or high viscosity - continuously and with high precision. The silcomix LSR-pump comes equipped with a new mixing system as well as innovative SWIPSYNC technology. This way, the liquid plastic may be delivered in an optimum manner in order to obtain high-quality end products.
The newly developed mixing system allows the user simple, intuitive, and fast handling with extended functions thanks to its compact design. An integrated 'Snuff-Back' function closes the valve opposite to the flow direction. The outflow rate is thus carefully controlled. In addition, the temperature of the new mixing unit may continuously be controlled while tool less maintenance intervals offer increased comfort. Thanks to the modular structure, the mixing unit may be accurately adapted to many different applications.
The precise compliance with the mixing ratio of A-component and B-component is utilised by the new SWIPSYNC technology. Here, the servo-electrical drives allow for the synchronous changeover between the piston metering pumps. This is done independently of the current position of the related pump piston and prevents the mixing ratio from shifting due to different changeover positions. The volume flows are automatically adjusted while the drums are drained evenly; material residues in the drum lie below one percent. At the same time, a special control of the servo drives significantly reduces the drop of the pressure and allows the volume to flow while also cutting down on the time required. Within the predefined tolerances, the mixing ratio remains constant during the injection molding process - no matter whether small or larger shot quantities are discharged.
Further outstanding features of the new silcomix: The extremely compact structure ensures a minimum footprint of less than 14 square feet. A drum roll-in device and preinstalled process interfaces to the automatic injection molding machine offer high user friendliness and ease of operation. In addition, automatic de-aeration functions for follower plates and pumps as well as step-by-step instructions on the touch display enable significantly reduced setup times.
DOPAG has been successfully operating in the key segment LSR for more than 25 years. With more than 800 systems sold, DOPAG belongs to the worldwide leading providers of high-quality technology for the production of LSR products. The success is based on a long-term partnership with renowned companies and project partners from a wide range of global industries. With the new silcomix PE 200/20, DOPAG is successfully expanding its position in the fast-growing LSR market and offers its customers worldwide the best conditions for ensuring their business success.
