I'm looking to get a detailed quotation for specialized inert gas/vacuum melt granulation furnaces capable of processing precious and common metals. Specifically, I need two models that come with 30kW induction capabilities. My focus is on granulating materials like gold, silver, copper, and tin, so I'd appreciate information on specifications, performance metrics, and any unique features that could enhance the granulation process. Additionally, please include details about pricing, delivery timelines, and any servicing options or warranties available for these furnaces. It would be great if you could share any insights on energy efficiency and operational costs as well. I'm keen to evaluate how these solutions could fit into my production needs, so comprehensive info would be valuable.
