The Italian association for plastics processors, Unionplast, has been collecting figures for many years with the aim of devising a feasible recovery and recycling system for end-of-life plastic products, and has carried out a market survey specifically regarding PVC pipes and pipe-fittings. This article provides details of the association s findings. UNIONPLAST... 

The Society of the Plastics Industry, Inc. is a trade association of over 2,000 members representing all segments of the plastics industry in the United States. SPI members include plastics processors, raw material suppliers, machinery manufacturers, mold makers and other industry-related groups and individuals. Founded in 1937, SPI serves as the voice of the plastics industry. 

Handbook for Plastics Processors, by J. A. Brydson, Heineman Newnes, Oxford, 1990 (in association with the Plastics and Rubber Institute). An excellent introduction with many detailed diagrams of equipment, a survey of major plastics materials and a brief section on the principles of product design. 

For the plastics processor, the application of coatings to the surface of molded parts adds cost, the uncertainties of adding liquids and the associated wet chemistry, and an additional operation that increases capital investment and broadens the quality control requirements.

The Web Watch directory, an online search engine of plastics industry-relevant websites, allows users to select from approximately sixty descriptions of companies or organizations (such as associations, blow molders, extrusion machinery suppliers, compounders, consultants, and so on). When searching for a certain type of processor, users can filter further by choosing the type of end market served (such as injection molders and medical). The search-results pages provide links directly to the sites that match your search parameters. Inclusion in and use of the Web Watch directory is free. 

Ejector locations. Ejection devices for plastic parts can range from screwdrivers used to pry parts out of a hand mold to mechanized stripper plates and elaborate mechanisms which also retract collapsible cores. All of them share one common characteristic they exert pressure on a newly formed part. That pressure can distort the part to the point of disturbing its function or appearance if it occurs while the part is still too soft to withstand it. Therefore, the processor must delay ejection until the moldment can endure it. The more ejectors there are, the more ejection surface there is to distribute that pressure and the sooner the part can be removed from the mold, thereby shortening the molding cycle. However, ejectors cost money and leave marks on the surface of the moldment. Therefore, there is a mold cost associated with a faster molding cycle. (Differences between bidders on a project are often based on variations in cooling and ejection systems.) Additional ejectors leave more marks on the surface and their number and location may be limited by functional and appearance concerns.
