Jiaozuo Coal (Group) Hejing Technique Co., Ltd

Most suppliers of silicon ingots come from regions with strong semiconductor manufacturing ties, like China's Jiangxi or Hebei provinces, where infrastructure and expertise are well-developed. Jiaozuo Coal (Group) Hejing Technique Co., Ltd. is based in Jiaozuo, a city historically known for coal, not high-tech materials — which makes their entry into silicon ingot production unusual. This shift suggests a possible diversification strategy, but the lack of verified work email, phone, or documents raises concerns about legitimacy and operational transparency. Being in business since 2008 shows they’ve operated for nearly two decades, which could indicate stability, but without verification, buyers must exercise caution. Buyers should request additional proof, such as a factory photo or product test report, before committing to any order.
