乐思化学塑胶镀工艺介绍 塑料镀应用领域 汽车 卫浴 电子 铝工业 海洋工业 器具、首饰业等 ABS和ABS/PC塑胶镀之优点 与金属材质比重量更轻，成本更低 形状设计可更趋于多样化和复杂化，且容易生产 无需机械处理如抛光或打磨等 可上镀多种金属镀层，获得想要的金属质感 粗化质量控制测试(粘合力) 控制粗化的温度、时间和化学浓度决定活性点的化学特性。粗化过少或过多都会影响粘合力。 在特殊的ABS或PC/ABS测试板上进行预镀处理，然后电镀50?的光亮酸铜用于粘合力测试。 良好的粘合力范围在5 – 12 lbs/inch之间，这取决于所使用的树脂和铸模条件。 乐思化学: 塑胶电镀界的领跑者 摘要 乐思是POP工业领域领跑者 是众多汽车POP电镀厂的合作伙伴 被OEM认可的产品和工艺 来自全球的技术支持 Questions?

Mechanical pre-treatment as used by metals as subtrates, like grinding and polishing is not necessary. Also parts with complex shapes can be produced on an easy way and at low costs. Especially for the automotive industry, low weight of plated plastic parts compared with metalic parts is very important. Other fields are sanitary and kitchen fittings, domestic articles, mobile phones, furniture fittings and a lot of more. The application of POP is getting wider and wider. The highest standard is required by automotive industries. Household appliances, plumbing , bathroom fittings are the most popular applications. Personal care like cosmetics and perfumes are being widely used. Plating on plastics are complicated and can generally be divided into 2 parts – pretreatment and electrolytic. Pretreatment starts from etching and then ends at electroless nickel. The first step is injection moulding. This is very critical to the performance of plating system. The design of the parts – whether you have round corner, easy to rack points, number of contact points, good temperature control, good flow of plastic resins all counts. ABS which is acryle nitrile butadiene styrene is the most popular plateable plastic. The next one is ABS and Polycarbonate mix blends. PC may range from 45% to 85%. These are widely used in Automotive industry to give strength, engineering performance. After electroless nickel are the e
