CNC Machining
A subtractive manufacturing process that employs computerized controls and machine tools to remove layers of material from a stock piece. Used for metal parts, custom components, and prototyping.
Rotational Molding
A manufacturing technique whereby a heated hollow mold is filled with a charge or shot weight of material, then slowly rotated to spread the material and form a hollow part. Ideal for making large, hollow products like tanks, bins, and recreational equipment.
Sintering
A process that fuses particles together by heating them below their melting point to create a solid structure. Frequently used in producing complex shapes in metals or ceramics that are difficult to form with other methods.
3D Printing (Additive Manufacturing)
An additive process that creates objects by laying down successive layers of material. Used for prototyping, customized products, and complex shapes that are hard to make with other methods.
Laminating
A process of creating a composite material by layering different materials and bonding them together. Used in the production of kitchen countertops, plywood, and laminated safety glass.
Blow Molding
A manufacturing process by which hollow plastic parts are formed. It is used predominantly for making products like bottles, fuel tanks, and containers.
Die Casting
A metal casting process that forces molten metal under high pressure into a mold cavity. Typically used for creating high-volume parts like automotive components, hardware, and appliances.
Injection Molding
A manufacturing process for producing parts by injecting molten material into a mold. Used for making plastic products like toys, automotive parts, and consumer electronics.
Sheet Metal Fabrication
A manufacturing process that involves cutting, bending and assembling sheet metal to create various products. Used for producing enclosures, brackets, and automotive body parts.
Lost-wax Casting
An ancient process that creates a metal duplicate of a wax model by melting away the wax and replacing it with metal. It is primarily used for jewelry and small precision parts with intricate details.
Extrusion
A process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Commonly used for making aluminum frames, plastic pipes, and wiring.
Stamping
A metalworking process that uses a press to shape metal by deforming it with a die. Commonly used to produce large quantities of identically shaped parts, like panels for car bodies and appliances.
Forging
A manufacturing process involving the shaping of metal using localized compressive forces. Forging is often used for creating parts that are stronger than those made by casting or machining, such as components for automotive, aerospace, and hardware tools.
Sand Casting
A metal casting process that uses sand as the mold material. It’s one of the oldest casting methods and is used for making large metal parts, like automotive engine blocks and machine tool bases.
Powder Metallurgy
A process of manufacturing metal parts by compacting fine powders and then heating them to create a solid piece. Used for producing gears, bearings, and other components requiring precise machining and material properties.
