We produce high quality castings for the auto industry using ‘sandcasting’. Foundry sand is an engineered material made of silica sand, binder, water, reducing agent & cushioning agent. It must withstand very high temp; extreme thermal shock & outgassing. The organic matter burns to form ‘sooty’ contaminants, thus after every cycle ~10% of the sand is replaced with new sand. Our new microwave heating technology aims to minimise the waste sand sent to landfill by burning off ‘soot’ at high temp. Our new idea is to develop this into a continuous process so that foundry sand can be cleaned more efficiently. This new technology would enable us to re-use most of our sand continuously, saving up to 80% in costs. It could reduce casting defects & scrap by 25%, reduce our carbon footprint, improve our competitiveness and in turn increase our sales. We would aim to license a systems manufacturer to build microwave furnaces for sale into the foundry industry in the UK, EU and possibly globally.

我们使用“砂型铸造”为汽车行业生产高质量铸件。铸造用砂是由硅砂、粘结剂、水、还原剂和缓冲剂制成的工程材料。它必须承受非常高的温度;极端的热冲击和放气。有机物燃烧后形成“不洁”污染物，因此在每次循环后，约10%的砂被新砂取代。我们的新微波加热技术旨在通过在高温下燃烧“烟灰”来最大限度地减少送往垃圾填埋场的废砂。我们的新想法是将其发展为一个连续的过程，以便更有效地清洁铸造砂。这项新技术将使我们能够不断重复使用大部分沙子，节省高达80%的成本。它可以减少25%的铸造缺陷和废料，减少我们的碳足迹，提高我们的竞争力，从而增加我们的销售额。我们的目标是授权一家系统制造商在英国、欧盟甚至全球的铸造行业建造销售微波炉。
