Ningbo/Michigan, USA – Ningbo HengHua Metal Surface Treatment Technology Co., Ltd. recently received a letter of appreciation from a well-known automotive parts manufacturer in Michigan, USA, highly praising the customized polishing solutions provided by HengHua Metal. By adopting HengHua Metal's specially developed automotive parts-specific polishing materials, the US customer's production line polishing efficiency increased by 35%, and the product defect rate decreased by 40%.
This US customer is a leading global supplier of automotive braking system components, providing products to many well-known automotive brands. In early 2022, the customer faced production capacity bottlenecks, and existing polishing materials could not meet the increasing production demands. After multiple rounds of technical exchanges and sample testing, HengHua Metal's technical team tailored a complete polishing solution for them, including special sisal wheels and high-temperature polishing paste.
"HengHua Metal not only provided high-quality products, but more importantly, a complete solution," wrote the US company's production director in a letter of appreciation. "Their technical team gained a deep understanding of our production processes and offered numerous suggestions for process improvements. After implementing the new solution, our production capacity significantly increased, while product quality became more stable."
HengHua Metal established a dedicated technical service team for this project, ensuring the smooth implementation of the solution through remote technical support and regular on-site services. Following the successful implementation of the project, the US client has listed HengHua Metal as a strategic supplier and plans to promote this solution in its other factories worldwide.
"This case fully demonstrates our ability to provide customized services," said the general manager of HengHua Metal. "We don't just sell products; we solve real problems for our clients. Every industry and every client has different needs, and we need to deeply understand these differences to provide truly valuable technical solutions."
HengHua Metal has already accumulated rich application cases in multiple industries, including automotive parts, hardware tools, and high-end kitchenware. The company plans to increase the proportion of customized business from the current 30% to 50% within the next three years, providing more international clients with personalized surface treatment solutions.
