Compression Molding of Rubber – A Practical Handbook

“Compression Molding of Rubber – A Practical Handbook” is the second book by Van T. Walworth, building upon rubber industry technology and know-how. This book focuses specifically on the technical aspects Van considers to be fundamental principles of compression molding of rubber products.  Some of the information presented in this book will be obvious and well known to many rubber molding practitioners, while at the same time, much of the content discussed in this book will not necessarily be considered basic, or even obvious, to those skilled in compression molding technology. From Van’s point of view, compression molding has not been replaced by transfer molding or injection molding, but rather, the process of molding rubber products has been expanded from compression molding to include transfer and injection molding.  Compression molding remains the most widely used process in the world of rubber molding.  Advancements in transfer molding and the installation of thousands of injection presses are somewhat offset by the ever-increasing market demand for rubber products.  As a result, compression molding remains a vibrant, valuable, and necessary molding process in the rubber industry, and yet may also be the most widely underutilized rubber molding process.
