Bending a plastic number plate can be done in several ways. One method is to use a heat gun to make the plate supple and then bend it by hand. Another approach is to use a hairdryer to heat the middle of the plate and gently bend it over your knee. Some people also suggest using boiling water and a shallow dish to heat the plate, being careful to only heat the middle and leave the ends untouched to avoid injury. It is important to note that bending a number plate may invalidate it, as severe bends can cause permanent marks and alterations to the plate's shape.

What You'll Learn
Using a heat gun
Bending a plastic number plate using a heat gun is a straightforward process. It is an affordable, versatile, and easy method for reshaping plastic. Here is a step-by-step guide:
Preparation:
Firstly, ensure you have all the necessary materials. You will need a heat gun, safety goggles, heat-resistant gloves, and a piece of plastic that you want to bend. It is important to choose a heat-resistant and pliable plastic, such as polycarbonate or acrylic. Additionally, you may require various nozzles for the heat gun, which can help direct heat to specific areas. Before you begin, make sure your work area is well-ventilated and free of any flammable materials.
Heating the Plastic:
Once you have gathered your materials and prepared your workspace, you can start heating the plastic. Put on your safety goggles and gloves, and then plug in your heat gun. Set the heat gun to a low temperature initially, and gradually increase it until the plastic becomes pliable. A temperature range of 200 to 500 degrees Fahrenheit is common for softening most plastics. Hold the heat gun about 2 to 4 inches away from the plastic and move it back and forth to distribute heat evenly. Avoid concentrating heat in one spot for too long, as this may cause warping or bubbling.
Bending the Plastic:
Periodically check the flexibility of the plastic by gently attempting to bend it. Once it is pliable, carefully bend it into the desired shape using your hands or a tool. You can continue to use the heat gun to reheat any areas that cool down and become less flexible. Be cautious not to overheat the plastic, as it may melt or deform.
Cooling and Final Steps:
After achieving the desired shape, allow the plastic to cool completely before handling it further. This ensures that the plastic retains its new shape and prevents unwanted deformation. Once cooled, you can drill holes or attach adhesive pads, nylon nuts and bolts, or screws to fix the number plate in place.

Bending by hand
Bending a plastic number plate by hand can be done in a few different ways. One method is to use a heat gun to warm up the plate before slowly bending it down. This can be done with the plate held in a vice between two pieces of wood, or by holding it over your knee. The plate should be held firmly in place as it cools to set it in the desired shape.
Another method is to use a hairdryer to heat the plate, which can then be gently bent. This method is less likely to damage the plate with excess heat. It is important to be careful and gentle when applying heat to the plate, to avoid melting or otherwise damaging it.
A third option is to use boiling water. By submerging the plate in a shallow dish of boiling water, it can be softened and made pliable enough to bend by hand.
It is worth noting that bending a number plate by hand may not always be effective or long-lasting. Some number plates may spring back to their original shape, and bending by hand may not produce a precise or permanent curve. To retain the desired shape, some users suggest taping the plate in place, or using adhesive pads or sticky foam pads to hold it in place.
In addition, it is important to consider the legality of modifying a number plate. While bending a plastic number plate is not explicitly illegal, it may be worth checking local regulations to ensure that any modifications are compliant.

Using boiling water
Bending a plastic number plate with boiling water is possible, but it requires careful execution to avoid damaging the plate. Here is a step-by-step guide:
First, it is important to understand that applying heat is the key factor in bending plastic. Boiling water is one method, but other heat sources such as a hairdryer, oven, or heat gun can also be used. When using boiling water, it is crucial to use caution and not overheat the plastic, as it can stress whiten and eventually break if overheated.
To begin the process, bring a pot of water to a boil on the stove. Ensure that you have a safe and accessible work area set up, with all the necessary tools within reach. This includes the boiling water, a pair of pliers or tongs, and a flat work surface. It is also recommended to have a bowl of cold water nearby to help set the shape of the plastic once it has been bent.
Next, using the pliers or tongs, carefully remove the plastic number plate from the boiling water. Take caution to avoid splashing or scalding yourself with the hot water. Once the plate is out of the water, you can begin the bending process. Use your hands or a flat surface to gently bend the plate to the desired angle. It is important to work slowly and carefully to avoid creasing or damaging the plastic.
After achieving the desired shape, immediately place the bent section of the number plate into the bowl of cold water. This will help to set the shape and prevent the plastic from returning to its original form. Hold it in place until it has cooled completely. If you are satisfied with the bend, you can attach the number plate to your vehicle using adhesive pads, nylon nuts and bolts, or other suitable methods.
It is worth noting that bending a plastic number plate may not always yield perfect results. Some people prefer to use aluminium or metal plates, as they are easier to bend and can be stuck on without the need for drilling or screws. Additionally, the use of a heat gun or hairdryer might be a more convenient option, as it allows for more precise control over the heat application.

Drilling and screwing
If you decide to use screws, you'll need to drill holes in your number plate. To avoid cracking your new plates, you should follow these steps:
- First, you need to mark the drilling points on your new number plate. You can use your old number plate as a template to mark the positions of the screw holes. If your old number plate is not suitable, you can use a large piece of paper as a template instead.
- Next, apply a small piece of masking tape on top of your drilling marks. This will help stop the drill from slipping and wandering when you start to drill.
- Now you're ready to start drilling. Place your number plate on a piece of scrap wood and carefully drill each hole through the plate in one go.
- Once you've drilled your holes, remove the masking tape from the plate. If there are any burrs or lumps, take them off. This will help your screws fit flush with the plate's surface.
- Finally, you can attach your number plate to your vehicle using screws. Position the plate in the correct location by partially attaching screws to both holes. Now carefully tighten up your fixings, ensuring you don't over-tighten them.
When drilling and screwing your number plate, it's important to note that you should only use screws if the screw holes are at the ends or top of the plate. Do not drill holes into or near the lettering as this will damage the characters. Additionally, make sure that the screws and screw covers do not interfere with the readability of your plate or alter any of the characters.

Taping into shape
To begin, the number plate should be fixed into the desired shape by taping it securely. This may involve taping the plate to the car itself, or to a separate surface that can hold the desired shape of the plate. It is important that the plate is held firmly in the desired shape, without any gaps or spaces behind it.
Once the taping is complete, the number plate should be left for a period of time to allow the plastic to retain the new shape. In some cases, this may only take a few hours, but it is recommended to leave it for a longer period, such as a week or more, to ensure the shape holds.
After the allotted time has passed, the tape can be carefully removed, and the number plate should retain its new shape. It is important to note that this method may not work for all types of plastic number plates, especially those made from acrylic, as they may crack or break if bent too severely.
Additionally, when taping the number plate into shape, it is crucial to ensure that the surfaces are clean and free of dirt, grease, or grime. This will help ensure that the tape adheres properly and securely. It is also recommended to avoid bending the plate at the points where it is fixed with adhesive or tape, as this can cause delamination and moisture issues.
