Explosives / Pyrotechnics

Gunpowder (black powder), smokeless powder, solid rocket propellants consist of mixtures of powdered binders, carbon / charcoal, sulfur, nitrates, reactive metal powders (titanium, aluminum) and/or an oxygen source (chlorates). Presses are used to form these materials into a more easily handled pellet or cylindrical form or to a specific density to control combustion.

Ferrites / Magnets

Metallic or ceramic (ferrite) magnetic powders are often compacted or formed using tableting presses. Ferrites are oxide compounds of iron or other metallic elements that exhibit magnetism due to alignment of spin dipoles of shielded electrons.

Fibrous Materials / Textiles

Compacting equipment for fibrous materials like cotton / cloth, synthetic / plastic, or cellulose fibers. Balers are typically used to palletize these types of materials.

Food Processing

Equipment for compacting solid and liquid-solid mixtures of food products such as cocoa, salt, grain, milk, dried potatoes, apples, sugar, spices, vegetables, or other foods.

Hazardous Solid Waste

Balers or other compacting equipment to process metal, paper, or other scrap materials or waste into a more compact and easy to handle form.

Laboratory / Analytical

Equipment for laboratory applications such as process parameter studies, material development or for preparation of analytical samples.

Mining / Ores / Minerals

Compactors for ores and minerals for subsequent transport, granulation or extraction processing.

Nuclear Fuel

Nuclear fuel uranium dioxide is typically formed into cylindrical pellets that are loaded into zirconium tubes. Tableting or powder compacting presses are used for simple flat shaped parts like pellets. Hot or cold isostatic presses are used to produce more complex shapes or increase final density.

Pharmaceutical / Sanitary

Equipment for pharmaceuticals or other sanitary applications. Tableting presses are commonly used to produce pills or tablets. The equipment is constructed of an easily sterilized material and is designed specifically for hygienic purposes such as medical, pharmaceutical, or food processing applications. Usually the equipment is certified by a national or international organization (USDA, FDA, etc.), but this is not required.

Polymers / Plastics

Equipment for forming compacts from polymers that cannot be melted such as polytetrafluoroethylene (e.g., PTFE, Teflon^®).

Powdered Metals

Equipment for the compacting of alloyed or blended elemental metal powders. Tableting or powder compacting presses are used for simple flat or multilevel shaped parts like gears or cams. Hot or cold isostatic presses are used to produce more complex shapes or increase final density. Powder rolling or roll compacting equipment is used to produce continuous sheets of metals for filter applications or with multiple composition layers.

Pulp and Paper

Equipment for compaction or pelletizing cellulose feeds, pulp or paper resins for production of paper, paperboard, particle board and other paper products.

Refractories

Refractories are metals or inorganic materials (bonded aluminum oxide, silicon carbide) with adequate strength at elevated temperatures. Refractories typically have high melting points, modulus, hardness and abrasiveness materials making a powder fabrication route an attractive choice. Tableting or powder compacting presses are used for simple flat shaped parts like ceramic washers. Hot or cold isostatic presses are used to produce more complex shapes like ceramic tubes or to increase final density.

Rubber

Balers are often used to palletize rubber, elastomeric materials, or scrap tires.

Saw Dust / Biomass

Equipment for compacting woodchips, sawdust, or waste into pellets or other forms for reuse.

	Your choices are...
	Briquetter		Briquetters compact a fine, powdered material into briquettes or chunks in order to improve handling, transportation, scrap disposal, storage or secondary processing. Briquetters often consist of a roller compactor with a serrated roller or a smooth roller combined with a granulator / chopper. Briquetters that form discrete cylindrical compacts are also available. Some briquetters are used for fluid extraction and recovery.
	Cold Isostatic Press		Isostatic presses utilize a chamber to compact the powder or material placed in a sealed tool, bag or other container. Cold isostatic presses (CIP) use an oil-water mixture pressurized up to 100,000 psi. Flexible rubber or plastic tooling and steel mandrels are used in CIPing. CIP applications include refractory nozzles, blocks, and crucibles; cemented carbides, isotropic graphite, ceramic insulators, tubes for special chemical applications, ferrites, metal filters, preforms, and plastic tubes and rods.
	Hot Isostatic Press		Hot isostatic presses (HIP) use an argon atmosphere or other gas mixtures heated up to 3000º F and pressurized up to 100,000 psi. Evacuated steel or metal cans or a sintered surface are used to contain and maintain a seal during HIPing. HIPs are used for densifying high performance ceramics, ferrites and cemented carbides, net-shape forming of nickel-based superalloys and titanium powders, compacting of high-speed tool steel, diffusion bonding of similar and dissimilar materials, and eliminating voids in aerospace castings or creep damaged blades.
	Pellet Mill		Pellet mills compress or extrude particles or fibrous materials into a cavity or die to form uniform cylindrical pellets. Compacted pellets are also formed using briquetters or tableting presses. Extruding pelletizers generate discrete and uniformly sized particles from a melt or a polymer (reclaimed scrap, post consumer or virgin plastic), liquid-solid pastes with a binder or other meltable materials. The melt or paste is extruded through a die with multiple orifices. The pellet is sheared off or chopped after cooling / drying. Several types of pelletizers are available such as hot face, air, and cold cutting and underwater.
	Roller Compactor		Roller compactors use smooth rollers to compact a ceramic or metal powder into a sheet or strip for filter applications, or for clad / bimetal production.
	Rotary / Multi-station Tableting Press		Punch and die presses with multiple stations or punches for compacting pharmaceuticals into tablets or metal powders into simple flat or multilevel shaped parts like gears, cams, or fittings. Rotary types have a series of stations or tool sets (dies and punches) arranged in a ring in a rotary turret. As the turret rotates, a series of cams and press rolls control filling, pressing and ejection. Pharmaceutical tablet and high volume metal part production facilities often use high-speed automatic rotary presses.
	Single Station Press		Presses consisting of a single station or tool set (die and punch set) in a die table. Single action opposed ram press use a die with both upper and lower punches. Anvil type presses have only a die and single lower punch. Single station compacting presses are available in several types basic types such as cam, toggle / knuckle and eccentric / crank presses with varying capabilities such as single action, double action, floating die, movable platen, opposed ram, screw, impact, hot pressing, coining or sizing.
	Other		Any unlisted, proprietary, or specialized tableting or powder press.
