Plastic is a common material used in homes for bins, cooking utensils, and home decorations. It may seem like a difficult material to work with due to its composition, but with little filing skill, you can shape it into virtually any object. To file down hard plastic, you will need to use a hand file or metal file. Unlike woodworking files, which have widely spaced teeth, hand files have teeth that are set much closer together and run diagonally across the blade, allowing for a smoother finish. When using a file, always push it in a forward or downward motion, as pulling it backward can damage the file.

What You'll Learn
Use a hand file or metal file
A hand file or metal file can be used to file down hard plastic. This tool is commonly found in garages, engineering shops, and metalwork shops. It is used to smooth rough edges and clean up welds on metal. However, it can also be used on other materials such as plastic, timber, and acrylic.
When using a hand file on plastic, it is important to follow a rhythmic technique to shape the plastic into an attractive finished product. Hold the coarse file in your dominant hand and grip the plastic section in your non-dominant hand. Tilt the plastic toward you at a comfortable angle. Then, tilt the coarse file away from your body in an upward position.
Place the rough side of the file at the top edge of the plastic and press it down. Push the file along the edge of the plastic in an upward and outward manner, moving away from your hand and toward the opposite end of the plastic. Continue this filing motion repeatedly until you achieve a smooth surface.
It is important to note that a hand file cuts on the forward stroke or push stroke and should not be used on the backward stroke or pull stroke. The teeth on the blade of the file are designed to work in a forward direction, and pulling the file backward can bend and permanently damage the teeth. Additionally, to achieve an extremely smooth finish, you can wrap a piece of emery cloth or fine-grade sandpaper around the blade of the file and move it back and forth over the surface.

File in a forward stroke
When filing down hard plastic, it is important to remember that the file cuts on the forward stroke or push stroke and will only work properly when used in this direction. The teeth on the blade of the file are designed to work in a forward direction, and pulling the file back can bend the teeth, causing permanent damage.
To file in a forward stroke, start by clamping your plastic firmly in a vice or Workmate. If you are filing down a significant amount of material or smoothing angles or curves, use a pencil or marker to mark the points that need to be filed down. Hold the file by its handle with one hand and use the other hand to hold the tip. Place the coarse file at the end closest to your holding hand and press the rough side down onto the edge of the plastic. Push the file along the edge of the plastic in an upward and outward manner, moving away from your body. Continue to file repeatedly until you achieve a smooth surface.
It is important to note that you should only bear down on the forward stroke when using a file. On the return stroke, lift the file clear of the surface to avoid dulling the teeth. This is especially important when working with plastic, as the wrong technique can quickly block up the teeth and make the file hard to use.
To achieve an even smoother finish, you can use emery cloth or fine-grade sandpaper. Wrap the emery cloth or sandpaper around the blade of the file and push and pull it over the surface in a backward and forward motion.

Use emery cloth for a smooth finish
To file down hard plastic, you can use a hand file or emery cloth for a smooth finish. Hand files have teeth set close together, allowing for a smoother finish. However, using emery cloth with your file can help you achieve a "mirror finish".
Emery cloth is a type of woven fabric with a greyish-black abrasive coating of corundum and magnetite on one side. It is sharper and more durable than sandpaper, making it ideal for metalworking. However, it can also be used on plastic for a fine finish. The smaller grain size of emery cloth makes it harsher than sandpaper, and it is available in various grits. For a fine finish on plastic, you can use emery cloth with a grit of 120 or above.
When using a hand file on plastic, it is important to note that it only cuts on the forward stroke or push stroke and will only work properly when used in this direction. To get a smooth finish, you can wrap a piece of emery cloth around the blade of the file and push and pull it over the surface until you achieve the desired smoothness.
If you are shaping plastic, use a coarse file and tilt it away from your body in an upward position. Press the rough edge of the file along the top edge of the plastic and push it outward and downward, moving inward toward your body. Continue filing until you create a smooth surface.

File in a rhythmic manner
To file down hard plastic, you must follow a rhythmic technique to shape it into an attractive finished product. This technique involves a repetitive back-and-forth motion with the file.
First, hold the coarse file in your dominant hand and grip the plastic section in your non-dominant hand. Tilt the plastic toward you at a comfortable angle. Next, tilt the coarse file away from your body in an upward position.
Now, you can begin the rhythmic motion. Press the rough edge of the file along the top edge of the plastic and push the file along the edge of the plastic in an upward and outward manner. Continue pushing the file toward the opposite end, where your hand is placed. Once you reach the end, remove the file and replace it at the beginning of the top edge.
Then, pull the file over and downward, moving inward toward your body. Continue this rhythmic motion, filing over and over along the plastic until you create a smooth surface. Remember to always push and pull the file in the same direction, as using a back-and-forth motion can damage the file.
Additionally, if you want an even smoother finish, you can wrap emery cloth or fine-grade sandpaper around the blade of the file and repeat the rhythmic motion until you achieve the desired smoothness.

Use a coarse file
To file down hard plastic, you can use a coarse file. This is a tool with teeth set close together that run diagonally across the blade, allowing for a smooth finish. Here is a step-by-step guide on how to use a coarse file to shape hard plastic:
- Hold the coarse file in your dominant hand, and grip the plastic section in your non-dominant hand.
- Tilt the plastic towards yourself at a comfortable angle.
- Position the coarse file away from your body in an upward tilt.
- Place the coarse file at the end closest to your holding hand, and press the rough side down onto the edge of the plastic.
- Pull the file over and downward, moving it away from your hand and inward towards your body. Remember, the file only works properly in the forward stroke or push stroke direction. Avoid using it on the backward stroke to prevent damaging the teeth.
- Continue to file repeatedly, following a rhythmic technique, until you achieve a smooth surface.
- If desired, use emery cloth, wet and dry paper, or fine-grade sandpaper to further smooth the surface and create a mirror finish.
By following these steps, you can effectively use a coarse file to shape and smooth hard plastic, creating a desirable finished product.

Frequently asked questions
You can use a hand file, also known as a metal file, to file down hard plastic. Unlike woodworking files, these files have teeth set very close together, allowing for a smoother finish.
First, clamp the plastic firmly in a vice or Workmate. Then, using a rhythmic technique, hold the coarse file in your dominant hand and grip the plastic in your non-dominant hand. Tilt the plastic toward you and tilt the file upward and away from your body. Press the rough edge of the file along the top edge of the plastic and push the file along the edge of the plastic in an upward and outward manner. Remember, files cut on the forward stroke, so be sure to only use the file in this direction to avoid damaging the file.
To get a smooth finish, wrap a piece of emery cloth or fine-grade sandpaper around the blade of the file. Then, using a forward and backward motion, push and pull the cloth over the surface until you get your desired finish.
