:: News from GPD Global

2-Part Mixing is now Volumetric Dispensing!

GPD Global, a manufacturer of precision fluid dispensing systems for high-volume 24/7, low-volume/high-mix, and R&D production, offers uniquely designed 2-part mixing pump to accurately mix and dispense two-part components while eliminating entrapped air.

Functions and Features - Volumetric 2-part mixing pump

The continuous volumetric 2-part mixing pump (2K or Bi Component or Two-Component Mixing) is based on volumetric Progressive Cavity Displacement (PCD) technology. This volumetric two-component mixer moves parts A+B fluid through a static mixer at an adjustable mix ratio. The two-components are uniformly mixed in the disposable static mixer - the only part wetted by both fluids. Static mixers are available in different sizes, lengths, and number of mixing elements - depending on the mixing requirements of the fluid. Unlike piston based mixing systems, recharge is not required.
The volumetric drive system is available in highly polished alloy or ceramic for abrasive fluids. The pumps are driven electrically for dispense rates up to 4.5 cc/min depending on configuration. The mix ratio is adjustable by controlling the speed of the individual pumps. This allows for a customized ratio; for example, a ratio of 1.2:1. Large ratios, up to 20:1, are also attainable.

Applications of the Volumetric 2-part mixing pump

The Volumetric 2-part mixing pump with its PCD technology enhances applications requiring two-component mixing by handling a wide range of fluids and being able to adjust the mix ratios to suit your needs. Below are some applications and materials that may be used with the pumps for metering or transferring:

  • Adhesives and sealants with or without spherical fillers
  • Encapsulant and potting fluids
  • Gasketing, dot, or bead applications
  • Suitable for two-component adhesive systems based on: epoxy resin (EP), polyurethane (PU), silicone (Si), methyl methacrylate (MMA), urethanes, UVs, sealants, etc.

Integration of the Volumetric 2-part mixing pump

PCD 2-Part mixing pump can be easily integrated into tabletop robots or fully automated platforms. The programmable controller allows you to calibrate the dispensing volume from each pump for accurate mix ratios. Interfacing to the controller requires a simple 24 V signal to initiate dispensing. More details about 2-Part Mixing Pump Integration.

Programmable Controller

The controller allows you to program the mix ratio of the pump and make final adjustments to the mix ratio, as well as calibrate the pump for appropriate volumetric dispensing. Time, volume, and on/off modes can be set to suit your dispensing needs. Up to 10 programs can be saved to the controller for selection.
Integration is simple - the controller easily interfaces with any robot via a 24 V external signal.
A reverse or suck back operation can be programmed to prevent dripping.
Refer to 2-Part Mixing Pump data sheet for more details about Programmable Controller.

:: International Expansion - Materion Boosts Target Productions

Materion has increased its global capacity for manufacturing planar and rotary targets to strengthen our commitment to customers in the large area glass coating industry. The new capabilities are a result of the March 2017 acquisition of the Heraeus target materials business in Hanau, Germany. In addition, Materion has just opened an expanded facility in Albuquerque, New Mexico.  This location will consolidate Materion operations with Heraeus’ large area glass target manufacturing from its previous site in Arizona to better serve the growing North American market.

Meanwhile in Germany, the groundbreaking for the construction of a new state-of-the art facility in Alzenau is a major step toward Materion’s goal of meeting the need for precious and non-precious target materials for the architectural and automotive glass, photovoltaic, display and semiconductor markets in Europe, Asia and the United States.

Grand Opening – Expansion in Albuqerque
A ribbon-cutting ceremony initiated the opening of Materion Advanced Materials new facility in Albuquerque, NM on June 14. The expansion involved consolidating Materion’s existing operations with that of Heraeus’ large area glass target manufacturing adding 25% capacity to the site and expanded capabilities such as rotatable target manufacturing. The Albuquerque site complete with new equipment will be manufacturing a new suite of large area glass target materials, particularly silver and other metals, compounds and alloys.

Global Milestone – Construction in Alzenau
A groundbreaking ceremony June 27 celebrated the future home of Materion Advanced Materials Germany GmbH in Alzenau. The 10,000 square meter building will provide a larger production area for increased capacity and state-of-the-art equipment for optimization of material flow. The timeline calls for the new facility to be ready for occupancy by December of this year.

The location in Europe expands Materion’s global presence. While construction proceeds, Materion is serving existing and new customers from the existing operations in Hanau, Germany.

More Capacity, Enhanced Technologies, Bright Future
With the expansion in Albuquerque and new construction in Alzenau, Materion is positioned to offer customers the broadest selection of precious and non-precious target materials globally. With access to the latest technology and R&D experts, we continue to offer quality products that provide superior performance.

Expansion On Target
The Materion name may not be familiar yet to some in the European marketplace, but customers of the former Heraeus target business group can rely on the same high quality products to which they are accustomed.  As the transition progresses, we will be provide updates on the construction and other plans that impact our customers.

:: Master Bond Two Component, Thermally Conductive Epoxy Resists High Temperatures

Formulated for bonding and sealing applications, Master Bond EP46HT-1AO is widely used in the aerospace, electronic and specialty OEM industries. Unlike most conventional two component epoxies, EP46HT-1AO cures with the addition of heat, which allows it to have a working life exceeding 24 hours. It has a forgiving 100 to 30 mix ratio by weight and bonds well to metals, composites, glass, ceramics and many plastics.

EP46HT-1AO combines thermal conductivity and electrical insulation properties. This dimensionally stable system provides a tensile strength over 7,500 psi, a compressive strength of 26,000 psi and a tensile lap shear strength greater than 1,500 psi at room temperature. EP46HT-1AO also withstands a variety of chemicals including oils, water, acids, bases and solvents.

This unique compound is serviceable over the temperature range of -73°C to +288°C (-100°F to +550°F) and offers a glass transition temperature of 215°C. It should be noted that EP46HT-1AO is relatively exothermic and should not be cured in sections greater than 20-30 thousandths of an inch thick and a bondline thickness is typically 2-7 thousandths of an inch.

This epoxy is available in ½ pint, pint, quart, gallon and 5 gallon container kits. Part A of this system is tan in color and Part B is moderately dark brown. EP46HT-1AO has a 6 month shelf life at ambient temperatures in original, unopened containers.

Master Bond Thermally Stable Adhesives
Master Bond EP46HT-1AO is thermally conductive and electrically insulative for bonding and sealing applications. This high strength, two component epoxy withstands temperatures up to +550°F.
