Metering Technology Hilger u. Kern / Dopag Group

There are a number of reasons why fibre-re­ni forced plastics are used increasingly in many There are three different manufacturing processes areas of industry, amongst which are: involved in the production of fibre-reinforced plastics • Its high strength coupled with low weight • RTM – Resin Transfer Moulding • Its ease of processing complex parts in small • RIM – Reaction Injection Moulding numbers • When the usual production technique is not economically justified or even not technically possible Such parts are used in many industries, including automotive and their subcontractors, aerospace,...

The compomix is a solvent free gear metering and mixing system. The range includes four types of systems • compomix 103 D • compomix 103 M • compomix 603 • compomix 603 V The compomix is used to handle low to medium viscosity multi component media such as polyurethane, epoxy or other resins for the production of fibre-reinforced plastics. Material pressure vessels are used to supply the material into the asynchronous motor driven gear pumps. Each gear pump is protected against over pressure and dry running as standard. A metering computer is used to control and monitor the system. A particular...

Equipment Standard • Control cabinet and material pressure vessels, • Static dynamic mixing system, with optional mounted onto a movable chassis • Gear metering pumps with over pressure protection with compomix 603 V, the gear metering pumps are mounted below the material level to feed under vacuum • Asynchronous motors • Metering computer MR15 with specific software for mould-filling speeds and mould pressure profiles (ramp operation when filling) • Monitoring and regulation of the mixing ratio and the flow rate through volume counters • Communication with external peripheral devices, for example...

Operating data The operating data of the metering system is The software used with the metering computers displayed on an 8” touch screen, other optional MR15 / MR30 has been developed specifically to meet the high requirements which are necessary The real time data is saved periodically (adjustable from 1 to 60 second) in a CSV format. The data can be loaded onto a USB stick via a USB port on the touch panel. The analysis can be made with an Office tool such as MS Excel. • Display and calculation of the flow rate and the mixing ratio • Display and regulation of the injection pressure, temperature,...

In addition, the compomix software has three timed stages. further special functions unique for the application The volumetric flow profile is based on internal mould pressure monitoring, so should pressure in • Metering with parameterised volume profile the mould reach the maximum allowed, the flow • Constant pressure regulated metering rate will be reduced automatically. • Follow-up pressure function The mixing ratio is regulated on the compomix. Constant pressure regulated metering During filling, pressure inside the mould increases. This pressure can influence the mixing ratio which therefore...
