How to Fix Deformed Plastic

As you know, plastic is a highly versatile material that can be used for various purposes. However, when it is not formed correctly, it can result in a deformity. In this article, we will show you how to fix deformed plastic using a few simple methods. Read on to learn more!

Deformed plastic is often caused by incorrect molding or poor-quality plastic. If the plastic is not good quality, it is more likely to warp or deform when exposed to heat or pressure. It can be challenging to fix deformed plastic, but it is possible. Many times, you can re-mold the plastic to fix the problem. However, if the deformation is severe, you may need to replace the piece of plastic entirely.

Summary: Fixing a piece of plastic that has been deformed can be tricky, but with the right tools and a little patience, it can be done. First, use a hot air gun to soften the plastic. Then, use a knife to cut out the deformed area. Finally, use a file to smooth the area.

How to Fix Deformed Plastic

What Can Cause Deformed Plastic?

There can be many causes for deformed plastic, but some of the most common include:

Improperly Heating the Plastic During Manufacturing or Processing: If the plastic isn’t heated to the right temperature or heated for too long, it can become deformed.

  • Exposing the Plastic to Extreme Temperatures (Either Hot or Cold): If the plastic is exposed to temperatures that are too high or too low, it can cause the plastic to warp or become deformed.
  • Poor Quality Plastic: If the plastic is of poor quality, it’s more likely to become deformed over time.
  • Poor Quality Materials Used in the Manufacture of the Plastic: If the materials used to make the plastic are of poor quality, they can cause the plastic to become deformed.
  • Poorly Designed Products That Place Too Much Stress on the Plastic Parts: If a product is poorly designed, it can place too much stress on the plastic parts and cause them to become deformed.

A Detailed Guide on How to Fix Deformed Plastic

Method 1. Fix Deformed Plastic With a Heat Gun

A heat gun is a powerful tool that can be used to fix deformed plastic. It uses heat to soften the plastic, which makes it easy to reshape.

Things You’ll Need:

  • Heat gun
  • Oven mitts
  • Safety glasses
  • Flat object (like a table)
  • Deformed plastic piece

Step 1:

Prepare the Work Area

Safety is the most important consideration when using a heat gun. Make sure the work area is well-ventilated and free of flammable materials. Cover any surfaces that could be damaged by heat.

Step 2:

Put on Safety Gear

Wear oven mitts to protect your hands from the heat. Put on safety glasses to protect your eyes from flying bits of plastic.

Step 3:

Heat the Plastic

Hold the heat gun about 6 inches (15 cm) from the deformed plastic. Slowly move the gun back and forth over the surface of the plastic until it becomes soft and pliable.

Step 4:

Shape the Plastic

Once the plastic is soft, you can mold it into the desired shape. Place the plastic on a flat surface and use your hands or a tool to push it into the desired shape.

Step 5:

Allow the Plastic to Cool

Once you’ve shaped the plastic, allow it to cool completely. This will help the plastic retain its new shape.


  • A heat gun can be used to fix a wide range of plastic objects, including those deformed.
  • It is a relatively simple process that does not require much expertise.
  • The results are often excellent.


  • A heat gun can be dangerous if not used correctly.
  • It can take some practice to get the hang of using a heat gun.
  • The results may not be perfect, and the plastic may still be somewhat deformed.

Method 2. Fix Deformed Plastic With a Clothes Iron

The clothes iron can emit just the right amount of heat to fix the plastic without melting it.

Things You’ll Need:

  • Clothes iron
  • Plastic item
  • Protective cloth or paper

Step 1: Determine The Heat Setting

The type of plastic will dictate what heat setting to use on your clothes iron. Use a lower heat for softer plastics and higher heat for harder plastics. Generally, it would help if you used the lowest heat to fix the plastic.

Step 2: Place The Protective Cloth or Paper

Place the protective cloth or paper over the area of the plastic that is deformed. This will protect the surrounding area from the heat of the iron.

Step 3: Iron The Deformed Area

Gently press the iron onto the protective cloth or paper. Hold it in place until the plastic appears to melt and takes on its original shape again. Remember to use caution as too much heat can cause further damage to the plastic.

Melt and Takes on Its Original Shape

Step 4: Let The Plastic Cool

Once the plastic has cooled, it should retain its new shape. If it is still deformed, repeat steps 2-4 until the desired result is achieved.

Deformed plastic can be a frustrating problem to deal with. But, with a bit of patience and the right tools, it can be fixed relatively easily. Use these steps to fix your deformed plastic and get it looking good as new.

  • Fixes deformed plastic without melting it
  • Easy to do at home
  • Can be done with household items
  • May require multiple attempts
  • Can damage the surrounding area if not careful

Method 3. Fix Deformed Plastic With Boiling Water

Boiling water can help to fix your deformed plastic items. Boiling water will make the plastic more flexible and malleable, allowing you to reshape it back into its original form.

Things You’ll Need:

  • Large pot
  • Boiling water
  • Deformed plastic item

Step 1: Prepare Yourself and Your Workspace

Wear protective clothing, including gloves and goggles. Boiling water can cause burns, so it is essential to take precautions.

Clear your workspace of any flammable materials.

Step 2: Boil the Water

Fill the pot with water and place it on the stove. Turn the stove to high and wait for the water to come to a boil.

Step 3: Submerge the Deformed Plastic Item

Once the water is boiling, carefully lower the deformed plastic item into the pot. Allow it to sit in the boiling water for a few minutes.

Step 4: Remove the Plastic Item From The Water

After a few minutes, use a pair of tongs to remove the plastic item from the water.

Step 5: Reshape the Plastic Item

Reshape the Plastic

While the plastic is still hot and malleable, reshape it into its original form. Once you have finished, set the item aside to cool and harden.

  • Boiling water will make the plastic more flexible and malleable.
  • You can reshape the plastic back into its original form.
  • Boiling water can cause burns, so it is essential to take precautions.
  • The plastic will become hot, so you will need to handle it carefully.

Frequently Asked Questions

Can You Reshape Plastic With Boiling Water?

This is definitely a fascinating question that has generated a lot of interest over the years. The short answer is that there is no clear scientific evidence to support the claim that boiling water can reshape plastic. However, this claim has been widely circulated online for years and there seems to be a lot of people who believe that it can actually work.

There are a few possible explanations for why boiling water may be able to reshape plastic. One theory suggests that the heat from the boiling water may be able to cause the plastic to break down into smaller pieces. Another theory suggests that the boiling water may be able to cause the plastic to melt. However, there is no evidence to support either of these claims.

So, while there is no clear evidence that boiling water can reshape plastic, it’s definitely an interesting claim and one that has generated a lot of interest online. If you’re interested in learning more about this topic, I recommend checking out some of the online discussions and research projects that have been conducted on this topic.

What Happens if You Boil Plastic?

If you boil plastic, it will become brittle and break apart. This is not good for the environment, as it will release harmful chemicals into the air. Additionally, boiling plastic will also leach plasticizers (detergents) into the water, which can be harmful to aquatic life.

At What Temperature Does Plastic Become Malleable?

Plastic becomes malleable at temperatures between 190 and 235 degrees Fahrenheit. This is due to the fact that plastic consists of a hydrocarbon backbone (containing carbon, hydrogen, and oxygen atoms) connected to an aliphatic sidechain (containing 20 or more carbon atoms). The heat causes the hydrocarbon backbone to melt and flow into the aliphatic sidechain, forming a flexible material called plastic.

Will a Hot Glue Gun Melt Plastic?

Here’s the answer – a hot glue gun will not melt plastic, but it may cause some minor burns if it comes into contact with the skin. Always use caution when using any hot glue gun, and make sure to hold it at a safe distance from your skin.


The plastic deformity is a common problem, but it can often be fixed with the right tools and techniques. So if your plastic is deformed, don’t despair – try some of these methods and see which one works best for you. With a little effort, you can have your plastic looking good as new in no time. We hope you have learned how to fix deformed plastic.
