Phenol Formaldehyde (PF). Phenol formaldehyde is known for its high strength, stiffness, hardness and its low tendency to creep. It is also known for its high toughness, and depending on its reinforcement, it will also exhibit high toughness at low temperatures. PF also has a low coefficient of thermal expansion. Phenol formaldehyde can be compression molded, transfer molded and injection-compression molded. Typical applications for phenol formaldehyde include distributor caps, pulleys, pump components, handles for irons, etc. It should not be used in direct contact with food. [Pg.31]

Injection-compression molding first injects the material into a partially opened mold, and then squeezes the material by closing the mold. Injection-compression molding is used for polymer products that require a high quality surface finish, such as compact discs and other optically demanding components because it practically eliminates tangential molecular orientation. [Pg.150]

Usually called injection-compression molding (ICM). Details are in Chapter 4. The essential difference when compared to IM lies in the manner in which the thermal contraction in the mold cavity that occurs during cooling (shrinkage) is compensated. With conventional injection... [Pg.453]

The CDs are manufactured either by injection compression molding or injection molding. Injection compression molding minimizes molded-in stress but requires longer cycle times than injection molding and produces flash. For both processes very clean room conditions, up to 1,000 times cleaner than medical molding, are essential. [Pg.782]

Injection compression molding (ICM) is, similarly to the gas injection technique and thermoplastic foam injection (TFI), particularly well-suited to making thick-walled moldings with little warping and few sink marks. However, thin-walled parts with long flow paths can also be produced efficiently by means of ICM. [Pg.192]

To form fine structures and to support the filling stage of high viscosity materials, the use of a mold with a vertical flash face for injection compression molding is useful. Figure 13 shows a mold with a molding with two surface structured cavities for the production of bipolar plates over a gap filling the mold. [Pg.317]
