Material Handling Applications with Metapor® Porous Materials



STUDIO CITY, CALIFORNIA: June 27, 2002: PORTEC - North America, a division of NEST Technologies, Inc., announced today new METAPOR porous materials for applications related to material handling. These applications include vacuum clamping tables and chucks, air-cushion devices, and powder fluidization systems.

Since its initial introduction in 1996, METAPOR micro-porous materials have gained popularity in the plastics industry mainly for production of air-permeable tooling for thermoforming processes. METAPOR is now widely used to make molds for production of rigid plastic packaging as well as components for automotive interiors, equipment enclosures, and other industrial areas that use vacuum formed plastic parts.

Over the years engineers from numerous industrial fields have also been applying METAPOR products to situations requiring even clamping forces using vacuum as well as even cushion forces using air pressure. The ever increasing number of these applications and specific customer requirements have led to this introduction of METAPOR porous metals and ceramics for a wide range of material handling applications.

All METAPOR porous materials are based on the proprietary formulation of metal or ceramic powders and epoxy binders. Using a patented manufacturing process the material is produced in plate form having a range of standard sizes. Unique nature of
METAPOR make it highly machinable without affecting its air-permeability, and multiple pieces are often joined together to create large porous structures.

At this time the most common material handling application for METAPOR is vacuum clamping. In the electronics industry METAPOR based systems are used for accurately holding down printed circuit boards, semi-conductor wafers, liquid crystal displays, and other delicate components. General machining and manufacturing industries use METAPOR to build flat and 3-D vacuum chucks in order to clamp parts for machining, trimming, assembly, and numerous types of other processes. In the medical industry, vacuum systems utilizing METAPOR are used for handling films, tubing, and other delicate materials.

METAPOR is also used to create air bearings and air cushion systems. Film converting industry uses METAPOR to create frictionless rolls. METAPOR air cushions are present in numerous packaging and automation lines for improvement of product handling. In the pharmaceutical, chemical, and food processing industries METAPOR is being utilized for powder transport and fluidization applications. When air flows through METAPOR
structures it fluidizes the powder materials enabling easy powder transport for packaging, controlled feeding, and dispensing.

The following METAPOR porous products are now available for material handling applications:

METAPOR BF 100 AL (aluminum based, micro-porous product)

This product offers fine surface finish, good mechanical properties, and temperature resistance of up to 230 degrees F. For vacuum clamping, this material can create a build-up of internal pressure allowing for adequate clamping of delicate components even though the complete holding surface may not be covered.

METAPOR BF 210 AL (aluminum based, heat resistant product)

This product has similar properties to METAPOR BF 100 AL, however, it can be used in high heat environments reaching temperatures of up to 460 degrees F.

METAPOR MC 100 AL (aluminum based, highly porous product)

This product offers 8 times higher air throughput than METAPOR BF 100 AL. This material is often used for construction of 3-D and flat vacuum chucks for machining, trimming, and assembly processes.

METAPOR CE 100 WHITE (ceramic based product)

This product is applicable for humid or wet environments as well as for clean rooms and other special applications.

METAPOR INOX 100 FE (stainless steel based product)

This product offers higher hardness and better abrasion resistance than other METAPOR products.
