What is Meter-Mix?
In the world of bonding, filling, and encapsulating the term “meter-mix” refers to the process and the hardware required to accurately manage, blend, and dispense multi-part fluids in an automated fashion. Most often in electronics and industrial dispensing, meter-mix dispensing is based upon processing a 2-part adhesive that is supplied as a base component plus a hardener component which when mixed in the proper volume and ratio cause a chemical chain reaction that initiates the curing process of the mixture. The reaction time can be as little as a few minutes up to hours or even days before achieving its final cured state. Once a 2-part adhesive is mixed, the end user should be aware of the specified “pot life” as this is the duration of time where the mixture can be used before the viscosity (or thickness of the liquid) increases beyond its useable state. In automated dispensing, once a mixture changes viscosity by even as little as 5-10%, this can have a negative effect on the consistency and repeatability of the process. Careful planning needs to take place to properly specify the correct metering and dispensing equipment.

Meter-Mix Applications
A 2-component adhesive formulation may be chosen over a 1 part adhesive due to performance benefits such as short cure times, enhanced durability, or improved adhesion. One of the most widely used applications of meter mix equipment is in the potting process where an enclosure with a circuit board is filled to a certain level to protect the electronics from moisture, dust, foreign objects, etc… A potting process can be applied to protect small electronic sensors used in the medical or automotive industry, or used to fill larger devices such as motor controller housings, LED video board assemblies, or electric batteries. A potting process can be a simple benchtop configuration where an operator may position a housing underneath a nozzle then step on a foot pedal to initiate the dispense into a single location for given amount of time or preset volume. In this case the viscosity of the potting material is low enough to freely flow into all required areas.

More intricate 2-component dispensing applications may require a multi-axis robot to drive a nozzle along a preprogrammed path to apply very small beads or deposits of adhesive to bond a mobile electronics assembly, or apply varying amounts of thermal gap filler materials with high accuracy to an automotive engine control module. Other precision applications may include staking of components to a circuit board or dispensing an encapsulant over exposed wire bonds. In these applications, the automation must be taken into consideration in order to apply medium to high viscosity adhesives at the proper flow rate and pattern in order to implement a successful process in production.

Product description: 
The two-component Mixing and Dispensing System accurately meters, mixes and dispenses two-component materials like potting compounds, encapsulants, casting materials and adhesives. The two components are precisely metered using gear pump technology, programmable from a simple control panel. The mix ratio, dispensing rate and dispensed quantity can be set-up quite accurately, providing consistent, error-free metering, mixing and dispensing. The control panel is menu-driven and password protected.
Our machine is designed with a unique modular approach, for simple configuration and maintenance. Each machine is built to match your material and process, with appropriate material reservoir sizes and dispensing hose lengths. Reservoir options include agitation, heating and drying (the latter for moisture sensitive materials like polyurethanes).
Material is fed from the two integrated gravity-fed reservoirs through the gear pumps where it is accurately metered, through flexible hoses to a dispensing head. Industry standard static mixing nozzles/ dynamic mixing  are used for homogeneous mixing. The mixture is free of air bubbles.
This metering, mixing and dispensing system is configured for standalone operation, triggered by a fingertip switch or foot pedal. It can also be configured to work with automation for consistently dispensed amounts and accurate placement.
The  Metering, Mixing and Dispensing System is able to process a number of materials including silicones, polyurethanes and epoxies.
