Chrome plating plastic model parts is a process that can give a premium, metal-like finish to plastic surfaces. It is often used to create a high-end look for decorative purposes, and is commonly used on car parts and household items. There are several ways to achieve this finish, including vacuum chrome plating, electroplating, and spray-on chrome. Each method has its own advantages and disadvantages in terms of cost, durability, and the level of expertise required.

What You'll Learn
Vacuum chrome plating
The process of vacuum chrome plating involves several steps to ensure a successful and even coating. Firstly, a catalytic film is applied to the surface of the plastic part. This step prepares the surface for the subsequent electro-less plating process. The part is then immersed in a final bath to remove any residual chemicals from previous treatments, ensuring a clean surface for effective plating.
The next stage involves electro-less plating, where a thin layer of copper or nickel is applied to the part without the use of an electric current. This conductive coating acts as a base for the chrome plating to adhere to. Once the electro-less coating is complete, a negative charge is applied to this metal layer.
The negatively charged part is then immersed in a tank containing positively charged chrome ions. These ions are attracted to the negatively charged copper or nickel layer and attach themselves securely, reverting to their neutral metallic state. This step ensures an even distribution of the chrome plate layer.
After removing the part from the chrome solution and allowing it to cool, a thorough inspection is conducted to ensure the quality of the chrome coating and verify that there are no discrepancies in the treated part. This process ensures that the chrome-plated plastic parts achieve the desired aesthetic and functionality.

Using chrome spray paint
Chrome spray paint is a cheap and easy option for chrome-plating plastic model parts. It can be done at home and is much more affordable than traditional chrome plating, costing only around 25% of the cost.
However, it is important to note that chrome spray paint is not real chrome. It will appear more like silver spray paint than a true chrome finish, and the base coat may show through if you are not careful. The layer it adds is thin and will quickly wear, possibly fading, peeling, or flaking.
To use chrome spray paint, you will need to apply a base coat to your plastic part. This can be done with a copper-based paint. Once the base coat is dry, you can apply the chrome spray paint. Be sure to follow the instructions on the product you have chosen and work in a well-ventilated area.
It is also important to prepare the plastic surface properly before painting. This may involve sanding or using a filler to smooth out any imperfections. You may also want to consider using a primer to help the paint adhere to the plastic.
Some people prefer to use a latex-based spray like Plasti Dip or Cardip.uk products, as these create their own 'cling' and can be removed in the future.

Copper-based conductive paint
To begin, you will need to purchase copper-based conductive paint, such as the products offered by Caswell Inc. or Surface Monkey Limited. These paints are designed specifically for chroming plastics and can be sprayed directly onto the surface without the need for a primer. The paint is water-based, non-toxic, and non-hazardous, making it safe and easy to work with.
Before applying the paint, ensure that your plastic model part is clean and free of any debris. Then, using a sprayer, brush, or roller, apply the copper-based conductive paint evenly to the surface. You may need to apply several layers to ensure complete coverage. Allow the paint to dry thoroughly, which typically takes about an hour.
Once the paint is dry, you can proceed to the next step of the chrome plating process. This typically involves dipping the painted part into a tinning solution and then plating it with an acid copper plating kit. The exact process may vary depending on the specific products and kits you are using, so be sure to refer to the manufacturer's instructions.
It is important to note that while copper-based conductive paint can provide excellent results, it may not give you a true chrome finish. For a more accurate chrome look, you may need to consider other methods such as vacuum chrome plating or using a chrome spray specifically designed for plastics. Additionally, keep in mind that chrome plating plastic parts may require multiple attempts to perfect, so patience and practice are essential.

Plastic fillers to fix defects
Chrome plating can be applied to plastic parts to give them a premium, high-end look. The process involves adding a layer of chromium to the substrate, resulting in a silver-grey, reflective, and mirror-like finish. This method can enhance the appearance of various items, from car parts to household items, giving them a metal-like surface.
When dealing with defects on plastic surfaces, it is essential to identify the type and severity of the issue. Minor scratches can be addressed by polishing the surface with mild abrasives, while deeper defects like cracks or chips may require the use of plastic fillers. These fillers can be applied to the affected areas, allowed to cure, and then sanded down to create a smooth surface. This process ensures that the original plastic part is repaired before proceeding with chrome plating.
Plastic fillers are effective in addressing surface defects, but it is crucial to ensure that the repaired areas are completely smooth and even before chrome plating. Any imperfections, no matter how small, can be magnified by the chrome plating process, resulting in an uneven finish. Therefore, taking the time to properly fill and sand the defects is essential to achieving a high-quality final product.
In some cases, more extensive repairs may be required before chrome plating. This could involve cutting open pipes on the seams and tapping back the low spots to remove dents or using micro TIG welding to fill in deep cracks or chips. While these methods can be more complex and time-consuming, they ensure that the plastic surface is flat and free of any imperfections that could be accentuated by the chrome plating.
Once the plastic fillers have been applied and the surface has been smoothed, it is important to consider the type of chrome plating that will be used. Traditional chrome plating, where the plastic part is coated in layers of nickel and copper before chrome is applied, is an option, but it tends to be more expensive and time-consuming. Alternatively, vacuum metalizing or PChrome, a spray-on chrome product, can be used for a more affordable and faster transformation.

Chrome film in stretch and non-stretch varieties
Chrome film is available in stretch and non-stretch varieties, both of which have adhesive backing. Stretch chrome can be used to wrap curved areas, while non-stretch chrome can only be applied to flat surfaces. Stretch chrome is the latest product in an exciting new line of car-wrap films offered by Alsa Corp. It retails for $5.99 per square foot. Similar to stretch chrome, FX sheeting is a peel-and-stick laminate that costs $14 per square foot. However, it does not have any stretch capabilities.
Chrome spray paint is another option for chrome-plating plastic model parts. This can be done at home and is more affordable than sending off your plastic parts for chrome plating. However, it may appear more like silver spray paint than a true chrome finish, and the base coat may show through.
