Coinjection Molding A hybrid technology, also known as multimaterial injection molding, that creates composite pieces made of plastic and metal parts locked together via injection molding or extrusion. The process combines the strength of steel with the corrosion-resistant properties of plastic. Overall weight is reduced, the need for exterior paint is eliminated and assembly and labor costs are slashed due to more efficient use of machinery. 

The Lotus Effect simulates the properties of the lotus flower in nature, by microstructured hydrophobic protrusions which enable surfaces to clean themselves by water in motion. By making use of innovative technologies, the Lotus Effect can be used on many different products. For example, self-cleaning surfaces could be used for self-adhesive films, injection moulded parts or painted components in the construction industry, for facade elements or window frames, for traffic facilities such as road signs, and not to forget cars themselves. 

In 1985, a USA paint manufacturer introduced a high-pressure injection molding IMG process (HPIP). It was based on injection of the coating into a closed mold at 300-400 bars pressure, before the SMC was fiiUy polymerized. At this stage, the compound is still compressible, allowing the coating to flow between it and the mold. The technology overcomes the objections to conventional IMG and is used today worldwide (Table 5.27). 

Textiles and artificial leather for vehicle interiors, carbon look and imitation wood foils for the dashboard, paint foils in the car color for radiator masks, decor strips, and door sUls. The remaining difficulties include the class A surface quality demanded by carmakers as well as so-called color-matching (same optical impression of sheen and color adjacent to conventionally painted parts). In these fields, the back injection process competes more directly with painting processes than with laminating processes. Here as well, this technology offers excellent opportunities for greater cost efficiency in future production processes (Figs. 28 and 29). 

It is possible to perform injection moulding with very high speeds, (i.e., with common cycle times of 10-30 s). A recent process called foiled FibrePur technology (FFT), which is a plastic-foil finishing technique in RIM based on long-fibre reinforced PU which produces fully finished painted parts in a single-step process [8, 9]. 

Oxygen lancing improves the combustion efficiency of air-fuel systems and reduces atmospheric emissions. This technology injects oxygen primarily to bum off feedstock contamination (e.g. oil, paint, organics, hydrocarbons).
