Compression molding process applicability

Microinjection Molding for Microfluidics Applications, Fig. 3 Simplified schematic of injection molding process (a) and injection compression molding process (b)... 

Through their large-part capability, the compression molding processes permit the combination of parts with the resultant assembly savings. They are also processes which offer economies of high volume. Thus, they are the processes of choice for large-part, high-volume applications. 

Preferred application areas for the pultnision process and continuous compression molding process... 

In this section, we will proceed to develop a finite element formulation for the two-dimensional Poisson s equation using a linear displacement, constant strain triangle. Poisson s equation has many applications in polymer processing, such as injection and compression mold filling, die flow, potential problems, heat transfer, etc. The general form of Poisson s equation in two-dimensions is... 

Another application of PTFE dispersions is the preparation of a variety of compositions with other materials, such as mineral fillers, other polymers in powdered form by co-coagulation. The dispersion of the other component is blended with the PTFE dispersion and the blend is then coagulated. The resulting composition can be processed by extrusion with lubricants (see processing of fine powders) or by compression molding.16... 

Compression molding—A process in which polymeric objects are formed in a mold by the application of heat and pressure. 

Melt compression molding identifies in-mold laminating and in-line molding of carriers, decorations, etc. The basic technique has been used for over a century. There has been an increased application of textile cover stock and leather substitutes both preferably with a soft touch. This type development was primarily initiated by the automotive industry with the objective to be prepared for future trends. Other industries such as furniture and packaging manufacturers use this process.
