Over the years the Investment Casting Foundry has developed steadily in size, sophistication and quality. Today foundries are processing hundreds of molds per day, in larger and larger parts with the tightest quality specifications in history. And so, every facet of production has been torn down and put back together in an effort to step up to those demands.

Dewax, burnout and preheat are no exception. With new quality standards such as ISO and TQM, every phase of production must be documented to assure a quality and repeatable product. Pacific Kiln has been working hard to meet this challenge with continuous furnace designs that are guaranteed to give the necessary performance and documentation that your quality specification requires.

Continuous furnaces are the only way to insure that each mold gets identical time, temperature and atmosphere treatment. As each mold progresses through the tunnel, it goes through the same program of temperature zones in the same rate of time and in the same oxygenated atmosphere. Management controls these settings and has a recording to evaluate against the quality of the part. REPEATABILITY.

There are two types of continuous furnaces normally used for processing the Investment Casting shell; The Pusher and the Car furnace.

THE PUSHER FURNACE has a hydraulic system that pushes load trays (ceramic or metal) through the furnace tunnel. There is a great variety of configurations; some burnout and preheat for pouring, some preheat only for pouring and some may want to cool the mold for inspection before reheating for pouring. The PUSHER can have as many temperature zones as desired and can be designed to process large quantities of molds per day. Mold size can be a limiting factor however, and this is where THE CONTINUOUS CAR FURNACE can pick up and be designed for any load size and weight. This system essentially incorporates all the features of the pusher but has these advantages: 1.) Can accommodate much larger load weights and sizes. 2.) Can be fully automated to reduce labor time and operator fatigue. 3.) The automated system is more operator safe. 4.) FlashFire Dewax may be incorporated to make a complete system, dewax to preheat and pour.
