Mold Engineering, 2nd Edition

Injection molds for thermoplastic molding materials and their performance are covered in detail in this book for mold designers, molding machine technicians, and design engineers. Guidelines are supplied for the design of molds, from product drawing to complete mold assembly drawing, and more.

“... directed at injection molding of thermoplastics ... the molding issues described are also relevant for other types of molding operations, including blow molding and molding of thermosets.”
