Design Pressure Dewaxing Machine for Investment Casting

2. Robust and Long-Lasting Structural Design
   The kettle features a dual-wall construction, with the inner vessel fabricated from high-tensile 345R alloy and the outer shell from durable Q235B carbon steel. This material combination not only reinforces structural integrity but also improves thermal retention, leading to higher energy efficiency during operation.

The door system employs a geared ring mechanism complemented by dual mechanical and electronic interlock systems, offering redundant safety assurance. A built-in inflatable seal achieves reliable pressure-activated closure once the chamber is pressurized. High-strength hinges and bearing bases—fitted with an opening limiter—prevent overtravel and mechanical failure, ensuring sustained operational stability over the equipment’s lifespan.
