Difficulties in electroplating this part

The part is 3D printed, resulting in a rough surface that cannot be polished. Due to the lower density of metal 3D printed parts and the presence of porosity, residual stress, and warping, even with polishing, it is impossible to achieve the same level of smoothness as CNC machined parts. Therefore, achieving a mirror-like effect on this part is not feasible. The maximum improvement in surface smoothness can be achieved through copper-nickel-chromium electroplating.

This part is an appearance component, so the requirements for the post-plating appearance are quite high. There should be no color difference between the inner and outer surfaces. Therefore, when using the rack plating method, it is important to ensure that the part is hung sideways instead of the traditional concave surface facing inward to ensure consistent color between the inner and outer surfaces.

Vacuum Deposition

（PVD）Vacuum deposition (PVD) Physical Vapour Deposition

Introduction to Vacuum Electroplating(PVD) Process

The vapor phase deposition method can be divided into physical vapor deposition (PVD), chemical vapor deposition, and discharge polymerization. Today, we will mainly introduce the physical vapor deposition method, commonly conducted in a vacuum environment, referred to as vacuum coating technology.

Characteristics of the PVD vacuum electroplating process

Vacuum coating, PVD electroplating, and characteristics of vacuum coating

PVD vacuum coating technology can create a metallic luster, with a uniform and durable surface appearance. It maintains a good appearance under various air and direct sunlight conditions. The colors are rich, bright, and economical, and reduce the time and cost required for cleaning and polishing. It is environmentally friendly with no chemical toxicity risks and has a wide range of biocompatibility.

Characteristics of PVD vacuum coating layer

PVD vacuum coating exhibits excellent adhesion. It can withstand more than 90 degrees of bending without cracking or peeling (PVD coatings have high adhesion and durability). Other technologies, including electroplating and spraying, cannot compare to their performance. It can etch any imaginable design pattern and can be used for interior decoration or in outdoor applications with oxidation and corrosion resistance.

Resistance of PVD coating

PVD vacuum coating layers have corrosion resistance, chemical stability, and acid resistance. They exhibit excellent characteristics such as oxidation resistance, non-fading, retaining gloss, and leaving no traces in conventional indoor or outdoor environments. They remain undamaged under normal use, do not fade, and are easy to remove paint and ink. They maintain their gloss, resistance to oxidation, non-fading, non-peeling, and non-cracking even in intense sunlight, high-salt wetlands, and urban environments. PVD vacuum coatings offer a wide range of colors, smooth and delicate surfaces with a metallic luster that never fades. The coating remains unchanged and stable in harsh environments such as strong sunlight and humidity. It is highly wear-resistant, scratch-resistant, and not easily scratched. It can be applied to a wide range of materials and has strong adhesion to the substrate.

Environmentally friendly process

PVD high-vacuum ion plating technology is truly friendly to human beings and the ecological environment. It is increasingly applied in modern industrial manufacturing purposes.
