Practical Injection Molding [Hardcover]

This work focuses on the factors critical to successful injection moulding, including knowledge of plastic materials and how they melt, the importance of mould design, the role of the screw, and the correct use of the controls of an injection moulding machine. It seeks to provide operating personnel with a clear understanding of the basics of injection moulding, resulting in more efficient processing, reduced cycle times, and better part quality with fewer rejects.Plastics; additives; loaders and dryers; injection unit; clamp unit; mould; control; robotics and granulators; getting started; an overview - the cycle; the ten keys to successful moulding; thermoset moulding; safety; recognizing moulding problems. Appendices: injection moulding materials; properties of common plastics; recommended plastic drying data; useful data; velocity control on injection moulding machines; procedure for applications of bolt torque on nozzle adaptors (end caps).
