Closed Mold Technology

Overview

Closed mold technology refers to composite manufacturing processes in which reinforcement materials are enclosed in a sealed mold cavity and resin is introduced under controlled pressure or vacuum. This approach produces parts with tight dimensional control, excellent surface quality, and repeatable mechanical properties compared to open mold methods.

2C Infusion Resin
The Eldo-Mix metering system range for the processing of unfilled vacuum infusion resins combine highly accurate metering pumps with extremely fast control engineering. The Eldo-Mix vacuum infusion resin system has a mix ratio monitoring and regulating control package to insure continuous and accurate metering ration accuracy of less than 1% deviation and the output rate during production can be modified in 2% steps

3C Glue Resins
The ELDO-MIX Glue Resin series metering \ mixing and dispensing system was designed to process the extremely high viscosity resins required to bond two composite components together

2C Gel Coat
The ELDO-MIX gel coat systems have been especiallydeveloped for processing highly thixotropic materials onto the untreated surfaces of rotor blades. By the use of gearmetering pumps\ which are also suitable for abrasive fillersand magnetically coupled axial piston pumps for the Bcomponent; output rates of up to 5 l/min can be achieved. The material supply of the mobile system is carried out frommaterial pressure vessels that are installed on the chassis. Not only can materials with viscosities up to the flow limit beapplied with this gel coat system, but also the mixing ratiosare adjustable within a wide range.
