A major polycarbonate market is the production of compact discs, DVDs, and Blu-ray discs. [13] These discs are produced by injection-molding polycarbonate into a mold cavity that has on one side a metal stamper containing a negative image of the disc data, while the other mold side is a mirrored surface.
Polymer solution casting technology can be deployed utilizing a host of different polymer materials depending on the application and design inputs, including those used in Class I, II and III medical devices, [2] and for the preparation of polymer electrolytes.

A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Melt blowing process Melt blowing is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. The randomly deposited fibers form a nonwoven sheet product applicable for filtration, sorbents, apparels and drug delivery systems.
Figure 1: Comparative Costs and Production Volumes For Processing of Plastics. The economics of plastics processing is determined by the type of process.Plastics can be processed with the following methods: machining, compression molding, transfer molding, injection molding, extrusion, rotational molding, blow molding, thermoforming, casting, forging, and foam molding.
The trend towards thin wall molding continues to increase in many plastic industries as plastic material and energy costs continue to rise and delivery lead times are squeezed. [2] The following industries make use of thin wall molding: food packaging ( e.g. food containers and lids) [3] automotive (e.g. both structural and non-structural car ...
When combining the activities with the concepts of the product structure model it will result in a process-data diagram. This diagram displays the steps which need to be taken within the process of product structure modeling together with the deliverables, at the right side, which are outcomes of these activities.
