    Injection blow molding is one of the main processes used in the blow molding industry. And although you may find information on this topic in general books on blow molding, the coverage is skimpy and lacking in details. None of them supply the sharply focused, essential information you will find in Samuel Belcher’s Practical Guide to Injection Blow Molding. Taking a straightforward approach, the book explores the entire industry from conception, design, costing, tooling, and machinery, to troubleshooting, testing, and daily production.

    The author, a highly knowledgeable industry insider, and a member of “The Plastics Hall of Fame,” discusses the history of the industry, as well as the ins and outs and dos and don’ts of its daily workings, reinforcing the information in the text with pictures, charts, and figures. He instructs in product and tooling design and material and machine selection, explaining the advantages and the disadvantages and elaborating on efficiencies that can be realized. The book also details basic costing procedures considering resin costs, machine costs, tooling, labor, energy, floor space, overhead, and sales and administration.
