紧固件由于有其独特的产品结构，在生产制造过程中，会遇到高温产生的顽固油脂等问题。美贝仕凭借多年的紧固件表面处理经验，在不锈钢、不锈铁等材料应用上的紧固件产品上，积累了丰富的紧固件钝化防锈和特殊的清洗经验。

Due to the unique product structure,fasteners will encounter problems such as stubborn grease generated by high temperature during the manufacturing process. With many years of experience in fastener surface treatment, KAIMENG has accumulated rich experience in fastener passivation and antirust special cleaning in stainless steel, stainless steel and other materials applied on fastener products.

针对紧固件这类产品的除油、抛光、钝化问题，大部分的厂家除油主要采取研磨方式，抛光可以用我们的MS0308-1抛光液处理后，再进行钝化处理，针对部分有缝隙、深孔的需要特别注意，抛光钝化有时候需要结合超声波使用，以达到处理掉缝隙、深孔内的残留药水以及钝化不彻底的问题。我们美贝仕凭借多年的行业经验成为铜材类紧固件表面行业的主要供应商，产品具有环保的认证报告，提供专业的工艺流程，帮助紧固件行业不断提高工艺效率。

For the oil removal, polishing, and passivation issues of fasteners, most manufacturers mainly use grinding to remove oil. Polishing can be treated with our MS0308-1 polishing solution before passivation treatment. For some products with gaps and deep holes, special attention should be paid. Polishing passivation sometimes requires the use of ultrasonic waves to remove residual solution and incomplete passivation in the gaps and deep holes. We, Meibeishi, have become the main supplier of copper fasteners in the surface industry with years of industry experience. Our products have environmental certification reports and provide professional process flow to help the fastener industry continuously improve process efficiency.
