Ajutor

This outstanding reference presents an up-to-date account of investigations during the last 10 years in the area of injection and compression molding of polymers.Injection and Compression Molding Fundamentals considers simulation andexperimentation of flow dynamics in the cavity and delivery system . . . discussesrheology and viscoelastic modeling … clarifies fiber orientation … delineates residualstresses and processing-property relationships in molded parts … and details computeraideddesign and manufacture of the mold.In addition, the book highlights specific features and problems related to the molding ofthermoplastics, rubbers, and thermosets … and reveals the current status of the sciencebasedtechnology related to injection and compression molding.The most detailed and authoritative reference of its type, Injection and Compression Molding Fundamentals is an invaluable resource for plastics, mechanical, andchemical engineers; colloid, oil, and color chemists; polymer engineers and scientists;mold designers and manufacturers; rheologists; and materials scientists. The book willalso be of value for use in graduate-level courses in plastics, mechanical, chemical, andpolymer engineering, and in short courses and seminars offered by professional societies.
