孟加拉采购需求：徽章、翻领别针、挑战币、奖牌、钥匙扣、皮带扣

I'm looking for a specialized production of a unique copper coin that dates back to 1839, associated with the East India Company. The specific coin should weigh around 25 grams and feature advanced technology embedded within it. The innovation I'm interested in is that this coin could slowly melt sugar at a consistent rate, targeting a timeframe of approximately 17 to 18 minutes. It's essential that the production process adheres to high-quality standards while integrating this technology effectively into the design. I'm keen to understand the feasibility of creating such a product, as well as any potential challenges in the manufacturing process. Your expertise in this area would be invaluable, so please share your insights and provide any relevant details that could aid in moving this project forward.
