The landed plunger type mold must have an accurate charge of plastic, and no flash is produced. It involves preheating thermoplastic foam sheets, which is then placed into an open, heated mold cavity and then closed with a top plug and compressed so that the pliable plastic material makes contacts with all areas of the mold. The operator would try to open the clam shell mold top, and then lean the top of the mold back against the press. Compression molding is a manufacturing process in which three-dimensional shapes are created using heat and pressure. Compression molding is a thermoforming process used to produce 3-dimensional molded foam and composite parts. One significant example are automotive applications where the leading technologies are long fibre reinforced thermoplastics (LFT) and glass fiber mat reinforced thermoplastics (GMT). Determining the minimum amount of energy required to heat the material. It is an ideal process for making parts that have intricate features, require very defined part geometry, have varying wall thicknesses or need to be held to critical dimensional tolerances.

Also, it is one of the lowest cost molding methods compared with other methods such as transfer molding and injection molding; moreover it wastes relatively little material, giving it an advantage when working with expensive compounds. It is designed to be used in compression molding process with 10% or higher compression rate. The first sheet was placed- one below a core and one sheet of equal size above the core, and then the top of the mold lowered by hand or by hoist to near shut. It is also widely used to produce sandwich structures that incorporate a core material such as a honeycomb or polymer foam, although care must be taken not to use excessive pressure that might crush the core. This means that there is likely to be variable consolidation across a shaped part. The WCM process allows the use of fast cure resin systems and therefore offers … As simple as it may sound, there are plenty of considerations when compression molding. About 2% of these are mattresses, 1% are protective packaging, and 1% are plastic sheets. Three-dimensional symmetrical and asymmetrical molded parts can also be produced quickly and economically. Three types of molds used are the flash plunger-type, straight plunger-type, and the "landed" plunger-type molds. With the evolution of compression molding, next was injection transfer.
