What's Electroplating?

Electroplating is one of the most common surface treatment processes for parts, applicable to both metals and plastics. Electroplating involves placing the metal to be plated as the cathode in a solution containing the desired plating metal, with the plating metal or another inert conductor as the anode. Through electrolysis under direct current, a firmly bonded metal film is formed on the surface of the substrate.

The purpose of electroplating is to enhance the appearance of the material while imparting various physical and chemical properties to the surface, such as corrosion resistance, decorative quality, wear resistance, solderability, and electrical, magnetic, and optical properties.

Identifying the Quality of Electroplating Processes

Good Appearance

Poor Appearance

The coating is thin (3-15μm), with a specified thickness tolerance of ±10%.

Good Precision

Poor Precision

The surface coating is consistent in every corner of the product, with high precision

Good Technique

Poor Technique

The coating has good adhesion and does not peel off.

Good temperature resistance

Poor temperature resistance

The coating has good adhesion and does not peel off.

FirstMold’s electroplating supplier has been working with us for over ten years and has been tested by hundreds of our customers. You don’t have to worry about any quality issues related to electroplating. We have extensive experience in electroplating rapid prototypes, injection-molded parts, and more.

Design Considerations of Electroplated Plastic Parts

材料选择

Plastic materials should ideally be electroplating-grade ABS

Defect-Free Surface

The surface of plastic parts must be free of defects.

Avoid Sharp Edges

The surface of plastic parts should preferably not have sharp edges.

Structural Strength

The structural strength of plastic parts should be good to prevent deformation.

Blind Holes

The depth of the blind holes should not exceed half the diameter to avoid poor electroplating at the bottom

Fixation for Weak Structures

The product design should include a reliable fixing structure to correct deformation defects after plating.
