For the production of economical and quality steel castings in foundries, an appropriate refractory coating is of utmost significance for better surface finish of casting. Different types of coatings as per the casting type and design are used in large quantities in foundries all over India. So, a micro start-up producing and supplying foundry coatings is inevitable and gives a huge scope and promise for future entrepreneurship. The Government of India has taken many initiatives to support Micro, Small, and Medium Enterprises (MSMEs), including financial aid (e.g.-CGSTME non-collateral loan -upto one crore for Micro Start-ups), market development, skill development and capacity building. But, inspite of government initiatives / policies and positive investor sentiments, a start-up in India is quite often failing due to lack of proper commercialisation planning and long-term sustainable goals. Micro level businesses are privately owned enterprises with limited workforce and revenue. They are known for their flexibility and ability to adapt to market changes. Nevertheless, they face challenges such as financial constraints, competition, limited bargaining power, regulatory complexities, and technological advancements. Notwithstanding these struggles, micro businesses contribute to the economy and local communities with their resilience, innovation, and community connections. But to achieve sustainability, a proper business plan, vision for future, Market analysis with SWOT study, Sales strategy with sales funnel forecasting, optimal PPC (Production Planning & Control) with adherence to licenses/rules of land, has to be achieved. This study aims to explore the market of foundry refractory coatings in Chhattisgarh, India, highlighting the significant impact of both the vast opportunities and vulnerable challenges in their growth.
