The rotational molding process is quite simple: A hollow mold is filled with powdered plastic resin. The mold begins rotating bi-axially and is transferred into an oven. The mold continues to rotate as the resin melts and coats the walls of the mold. The mold is cooled until the resin hardens into the desired shape.

Thermoforming is the process of heating a material to its forming temperature and applying force to the hot sheet to push it into cavities or over a mold so the material conforms to the shape of the mold. The forces applied are any of three different methods: mechanical assist (plugs), vacuum, and form air

Compression molding is the process of molding in which a preheated polymer is placed into an open, heated mold cavity. The mold is then closed with a top plug and compressed in order to have the material contact all areas of the mold.

Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession.

In its simplest form, the process involves pushing molten polymer through a circular or slot die. This continuous process enables the production of a consistent high quality product to extremely accurate gauge. For most thin gauge films, the film extrusion process takes the form of blown or cast extrusion

The basics of foam extrusion consist of mixing a chemical foaming agent with the polymer to be extruded. The heat generated to melt the polymer decomposes the chemical foaming agent resulting in gas being liberated. This gas is dispensed in the polymer melt and expands upon exiting the die.

Blow molding (or moulding) is a manufacturing process for forming and joining together hollow plastic parts. It is also used for forming glass bottles or other hollow shapes. ... The parison is then clamped into a mold and air is blown into it. The air pressure then pushes the plastic out to match the mold.

A pipe extrusion line consists of a number of pieces of equipment. An extruder converts the polyethylene raw material to a continuous tubular melt by extrusion through an annular die. The molten pipe then proceeds through a sizing or calibration device (which fixes its dimensions) to a cooling trough.

A work stage in which plastic raw material is melted and extruded at high pressure and temperature, forcing it into the cable's structure. Extrusion is most commonly used for wire insulation and to form the outer sheath of the cable.

Sheet extrusion is a technique for making flat plastic sheets from a variety of resins. The thinner gauges are thermoformed into packaging applications such as drink cups, deli containers, produce trays, baby wipe containers and margarine tubs.

Filaments are a type of fiber having indefinite or extreme length, such as synthetic fibers which can be made to any length; From: Identification of Textile Fibers

The polymeric coating process comprises applying a polymeric material onto a supporting substrate and coating the substrate surface. Polymeric coatings can be obtained using natural and synthetic rubber, urethane, polyvinyl chloride, acrylic, epoxy, silicone, phenolic resins or nitrocellulose, etc

Compounding consists of preparing plastic formulations by mixing and/or blending polymers and additives in a molten state to achieve the desired characteristicsThere are different critical criteria to achieve a homogenous blend of the different raw material. Dispersive and distributive mixing as well as heat are important factors.

Most common epoxy resins are produced from a reaction between epichlorohydrin (ECH) and bisphenol-A (BPA), though the latter may be replaced by other raw materials (such as aliphatic glycols, phenol and o-cresol novolacs) to produce specialty resins. The epoxy resins can be obtained in either liquid or solid states.

Depending on produced goods (boxes, caps for PET bottles, etc.) our Reports include data of grades with MFI from 6 to 120. Major volumes of injection molding grades belong to MFI 8-12.
