Trivalent Chromium Plating for Plastic Parts
Today, industrial parts manufacturers can make their products more competitive in the marketplace by using a variety of surface treatments. This capability enables designers of some plastic components to alter or modify specific exterior qualities, such as electrical conductivity, texture, color, and more. Frequently, companies choose to apply several surface treatments during the finishing stage in order to produce plastic parts meeting specific objectives. Trivalent chromium plating has become a widely-used surface treatment in some industries.

Application Domain for Trivalent Chromium Plating for Plastic Parts
As the world health agencies and the European Union are paying more attention to the implementation of environmental protection policy and trivalent chromium itself belongs to a greener process.
a.Highly suitable for applications in the automotive, sanitary, consumer and electronic goods industries
b.Suitable for plastic-based applications such ABS, ABS+PC and so on.
Nowadays,trivalent chromium electroplating has gained widespread acceptance as a way to apply a lustrous chrome finish to plasticcomponents. More and more car manufacturers are tending to use such process alternative to traditional chromium.
Trivalent chromium plating on automotive plastics is mainly used in the manufacturing of auto parts.Please see the following details;
1)Exterior trim parts: Automobile exterior trim parts such as door handles, rearview mirror housings, front grilles, etc. usually need to have good display performance and durability. Through trivalent chromium plating, a thin film with metallic luster and corrosion resistance can be formed on the plastic surface to improve the texture and durability of exterior parts.
2)Interior parts: Automotive interior parts such as instrument panels, central control panels, door panel trims, etc. also require good appearance and wear resistance. Trivalent chromium plating can form a delicate and smooth metallic texture on the surface of interior parts, improving the quality and luxury of the overall interior.
3)Chassis and mechanical components: Automobile chassis and mechanical components such as sensors, switches, connectors, etc. usually require good corrosion resistance and conductive properties. Trivalent chromium plating can form a metallic protective layer on the plastic surface to improve the durability and stability of the chassis and mechanical components.
In general, trivalent chromium plating for automotive plastics is mainly used to provide the metallic appearance, texture, corrosion resistance and durability of plastic products. It can also improve the mechanical properties and electrical conductivity of plastic products to meet the automotive industry's requirements for high quality and high performance. Demand for performance plastic accessories.

What Inspires Us
Why we develop the trivalent chromium process over plastic
Market-driven challenge
The interest in sustainable surface finishing is growing due to regulations such as RoHS, ELV, WEEE or REACH, as well as increased environmental, health and safety awareness. However, the demand for surfaces with a Cr(VI)-like appearance and excellent corrosion protection is coming from all industries where decorative applications are required.
Our solution
Our trivalent chromium processes for decorative applications are a sustainable alternative to hexavalent chromium plating. Our advanced automatic product line fulfills the highest design requirements for customers and offers a broad range of different shades. They also offer excellent corrosion protection.

Typically, trivalent chromium electroplating solutions rely upon either chloride or sulfate-based electrolytes. The process of trivalent chromium electroplating usually requires several steps between chemical treatment and electroplating process. Variations exist in production technologies.Usually,our production line must first thoroughly clean a work piece to remove debris and grease. Depending upon the composition of the part,we'll apply one or more pretreatments. For instance,we first electroplate parts with nickel prior to applying decorative chromium plating.
Trivalent plating produces at least five percent fewer rejects than hexavalent plating. You'll save money on scrap metal and can plate more parts in the trivalent bath, which will increase production. Trivalent plating also boasts: Fewer toxic fumes than hexavalent plating.
