Extrusion Molding
Extrusion molding is a type of thermoplastic molding process in which plastic is pressed through a die orifice to create a desired shape. During the process, a plastic material, such as a compound or a polymer, is melted and forced through an opening in a die. The shape of the extrudate, or extrusion, which is the shape of the product, is usually determined by the shape of the die. The extrusion molding process can be used to produce a wide array of items, such as pipes, tubing, rods, wire and profiles.
Injection Molding
Injection molding is a type of manufacturing process in which parts or products are created by forcing molten plastic material into a mold cavity. During the injection molding process, a plastic material is heated, injected into a mold and cooled, and then released from the mold. The material is then shipped to a finished parts plant, where it is trimmed, cleaned, assembled and packaged as necessary. Injection molding is used to produce a variety of parts, including containers, electrical components, automotive components and consumer products.
compression molding
Compression molding is a process used to fabricate parts from thermoplastic and thermoset materials. During the process, a pre-shaped die or form is clamped between two halves of a heated mold. Under high pressure, the material flows into the cavities of the mold and takes on the shape of the die. The material is then cooled, removed from the mold and trimmed to produce a finished part. Compression molding is typically used to produce large parts to tight tolerances and with a highly uniform finish.
Blow Molding
Blow molding is a manufacturing process in which hollow plastic parts are formed by forming molten plastic around a mold cavity. During the process, molten plastic is injected into a closed mold, where it forms around a core and the shape of the mold cavity. The plastic is then cooled, released from the mold and trimmed to produce the finished part. Blow molding is commonly used to produce bottles, containers and other hollow shapes.
Vacuum Forming
Vacuum forming is a process in which plastic sheets are heated, stretched and forced onto a mold to form a part or product. During the process, a sheet of plastic is heated, stretched and forced onto a mold with vacuum pressure. The sheet is then cooled, released from the mold and trimmed to produce the finished part. Vacuum forming is used to produce parts for a variety of industries, including medical, automotive, aerospace and consumer products.
Rotational Molding
Rotational molding is a process used to fabricate parts from thermoplastics and thermoset materials. During the process, a pre-shaped die or form is placed into a heated mold and rotated along two or more axes. As the die rotates, the material is melted and forced into the mold, where it takes on the shape of the die. The material is then cooled, released from the mold and trimmed to produce the finished part. Rotational molding is used to produce a variety of parts, including tanks, containers and automotive components.
