Description:
It has always been my ambition to produce a book and workshop manual on Lost Wax Casting incorporating all the knowledge I have gained in operating the process in various parts of the world for nearly 60 years. Now that I have sold my last business and retired, I have the opportunity to fulfill my ambition and to get all my experience down on paper, and give new and experienced casters alike a useful and informative guide to the process I have had the privilege to develop and work with throughout my life. I have now spent nearly a lifetime Designing and Manufacturing Jewellery using the Lost Wax Casting process, also producing Precision Investment Lost Wax Castings for Industry and… researching and writing this book about this wonderful process which has occupied nearly my whole life and in spite of my many highs and lows during that time, I still feel that I would not have missed a minute of it. I have achieved something special in my life and it brings me great pleasure now when I am able to help someone with their casting problems and I look forward to hearing from you. Firstly I would like to introduce myself, I have been producing lost wax castings for over 50 years, man and boy, in the last 10 years, I decided I did not want all my knowledge to be lost when I die, so I decided to write this book and to put in all my life s experiences good and bad, in the early days the were Dental Mechanics using Lost wax casting to produce the metal parts of teeth, plates etc. and there were a few companies supplying Chemicals (Investment), Machinery, Hand Tools, Drills, Burrs, Etc. Etc, Etc. the one I worked the mostly with was a firm called Nesor Products as their family name was Rosen , In those early days they even agreed to manufacture machines for us, as we where much more involved in quantity rather than the Dentists, as the were mostly involved in 1 offs, as each item fitted mainly one patients, as many times, to make to Plates fit properly, the Dentist got the patient to bit on a special piece of wax, so that they obtained a near perfect fit, Then once we were in production, we used many different types of Chemical Companies, Engineering Companies, and with the Investments Suppliers. THE BASIC PRINCIPLE OF LOST WAX CASTING The problem associated with the first forms of casting, was the removal of the original pattern or model, therefore the process of lost wax casting is based on the use of a disposable pattern; which will burn totally away at high temperature, in an oxidizing atmosphere. It is possible therefore to cast from any vegetable matter that, after having been encapsulated in a suitable refractory type material, is capable of being burnt away at high temperature to allow the metal that you which to cast in to be melted and poured in to take its place. In lost wax casting, the chosen vegetable material will be wax, in the beginning Bees wax was used, the wax was modeled by hand but in more modern times many different waxes have been developed, some for carving the original model, which can be cast in metal, cleaned up and used as a production model from which are rubber mould is made if you are producing Jewellery, Ornaments or Statues, but in the case of Industrial Precision Investment casting instead of making a model and then producing a rubber mould from which the wax patterns are made, the mould is produced in metal, which gives much more accurate dimensions for the finished castings. The book is split into five sections, in which I will cover a wide variety of aspects of Lost Wax Casting: 1. History of Lost Wax Casting 2. The Theory of Lost Wax Casting 3. Step by Step Picture Guide 4. Workshop Manual 5. Autobiography All of the sections are designed to give you a through picture of where the Lost Wax Casting process came from, the various ways in which the process has been used, and how it is still used today in a myriad of industries, from Dentistry, through to Jewellery Making, and even in the production
