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.
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 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 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 compactors use smooth rollers to compact a ceramic or metal powder into a sheet or strip for filter applications, or for clad / bimetal production.
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.
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.
Any unlisted, proprietary, or specialized tableting or powder press.

Equipment suitable for high hardness materials such as abrasives, ceramics, ferrites / magnetic materials, or refractories. 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.
Hot isostatic presses are commonly used to eliminate internal porosity in as-cast components as well as creep induced porosity in jet engine blades or other aerospace components.
Carbide parts and cutting tools are typically fabricated with compacting equipment. The pressing and sintering process maintains a fine crystal size that improves wear resistance and toughness. Simple carbides or cutting tool shapes are processed with tableting or powder compacting presses. Hot or cold isostatic presses are used to produce more complex shapes or to increase final density.
Compaction of powders to provide electronic or semiconductor materials that cannot be formed through a conventional fusion process. Also includes the compaction of electronic or semiconductor materials in a preform shape for subsequent processing.
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.
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.
Compacting equipment for fibrous materials like cotton / cloth, synthetic / plastic, or cellulose fibers. Balers are typically used to palletize these types of materials.
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.
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.
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.
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.
Equipment for compaction or pelletizing cellulose feeds, pulp or paper resins for production of paper, paperboard, particle board and other paper products.
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.
