What You'll Learn
Use hot air to soften plastic
To reshape plastic, hot air can be used to soften it. This method is commonly used in process heat, crafts, and hobbies. It is effective on materials such as tubes or plexiglass.
When using hot air to reshape plastic, a heat gun is often employed. This tool can generate extremely high temperatures, similar to a super-powered hair dryer, and can cost as little as $10-15. The high heat from the gun softens the plastic, allowing it to be manipulated into the desired shape. It is important to note that the temperature and heating time will depend on the specific type of plastic being worked on.
Once the plastic has been sufficiently heated and softened, it can be reshaped. It is important to understand that the plastic will not cool down and harden quickly. This allows for a reasonable amount of workability time, providing the opportunity to pose or mould the plastic as needed. However, if a quick cool-down is desired, the plastic can be doused with water, which will rapidly decrease the temperature and lock in the new shape.
Using cold tap water is generally recommended for cooling down softened plastic. It is sufficient to restore the plastic to a solid state, and there is no particular benefit to using ice water. The rapid decrease in temperature caused by the water helps to form new molecular bonds, locking in the reshaped structure.
Overall, using hot air to soften plastic for reshaping is an effective method, especially when combined with water cooling. It is important to be cautious when working with high temperatures and to follow the necessary safety precautions.

Dip plastic into hot water
Dipping plastic into hot water is one of the most common techniques used to reshape plastic figures. This method is often preferred over using a heat gun or hair dryer as it is more cost-effective and safer, with less risk of burning the plastic or one's self.
To begin the process, one must boil water in a large pot or crockpot. The amount of water needed will depend on the size of the plastic object being reshaped. Once the water has reached a rolling boil, the user can carefully dip the plastic figure into the hot water. It is important to hold the plastic figure with a rag or tongs to avoid burning oneself.
The plastic will need to be soaked in the hot water for at least 30 seconds to ensure the area is sufficiently heated and pliable. The figure can then be removed from the water and adjusted to the desired shape. It is worth noting that the plastic will not cool down immediately, so there will be some time to adjust the shape before it begins to harden again.
After achieving the desired shape, the plastic figure should be dipped into cool water to set the new shape in place. This step is crucial as it helps to quickly lower the temperature of the plastic, locking in the new shape. The water should be cool but not icy cold, as regular cold tap water is sufficient to harden the plastic.
Overall, the "dip and shape" method is a simple and effective way to reshape plastic figures. With some care and attention, one can easily adjust the shape of their plastic figures without the need for expensive equipment.

Use an oven to reshape large objects
To reshape large plastic objects using an oven, you will first need to ensure you have a clean and safe working area. Make sure your space is well-ventilated and keep any flammable materials away from your workspace. Open some nearby windows and turn on your oven's fan to prevent the build-up of toxic fumes.
Next, preheat your oven to around 300 °F (149 °C). This temperature will gradually melt most common plastics. Place the plastic object inside a heat-proof container, such as a cheap sheet pan or a ceramic tile, ensuring that it fits entirely inside the oven. It is important to prevent melted plastic from spilling onto the oven's surfaces, as it can be challenging to remove.
Once the oven reaches the desired temperature, place the heat-proof container with the plastic object inside and allow the plastic to melt gradually. Watch the plastic as it melts to avoid burning it. You can do this by turning on the oven light and observing through the window in the door. Remove the plastic from the oven using oven mitts once it has melted but before it starts to smoke or burn.
While the plastic is still hot, you can pour it into a mold to achieve the desired shape. You can use a pre-made heat-resistant mold or create your own, especially if you have a specific shape in mind. If you want to cut the plastic into a new shape, let it cool in the melting container before reshaping.
Always exercise caution when working with heat and prioritize your safety. Ensure you handle the hot plastic with oven mitts or tongs to avoid accidental burns.

Shred plastic into flakes for extrusion
Shredding plastic waste is an important step in the recycling process, as it prepares the plastic for reprocessing. Shredding plastic into flakes specifically is useful for applications such as compression moulding, highly reinforced composites, powder coating, and 3D printing. The process of shredding plastic into flakes for extrusion involves several key steps, each contributing to the overall quality and efficiency of the final product.
Firstly, it is essential to collect, sort, and separate plastic waste by material type. This step ensures that different plastics, which have varying properties and melting points, are not mixed together, preventing inconsistencies in the final product. Once sorted, the plastic waste must be thoroughly cleaned to remove contaminants such as stickers, tags, dust, and liquids. This cleaning process is crucial for maintaining the quality of the final product and preventing blockages in the extruder due to unmelted contaminants.
After sorting and cleaning, the plastic waste is ready for shredding. It is recommended to break large plastic items into smaller pieces before feeding them into the shredder to avoid overloading and potential malfunctions. The shredding process reduces the plastic waste into small, uniform flakes, which can then be agglomerated or pelletized. Agglomeration involves combining the plastic flakes to form larger, uniform pieces, while pelletizing creates plastic pellets of consistent size and shape through processes such as extrusion and melt filtration.
The extrusion process is a critical step in reshaping plastic flakes into the desired form. During extrusion, the plastic flakes or pellets undergo mixing, homogenization, compression, and plasticization. This involves heating the plastic material to soften it and pushing it through a die or mould to create the desired shape. Additives such as colouring pigments can also be introduced during this stage to customize the final product.
Overall, shredding plastic into flakes for extrusion requires careful sorting, cleaning, and shredding processes to ensure the final product is of high quality and free from contaminants. The extrusion phase then allows for the reshaping of the plastic flakes into a variety of forms, contributing to the sustainability and versatility of plastic recycling.

Heat plastic with a hairdryer or heat gun
Using a hairdryer or heat gun to soften plastic is a common practice, but there are some important things to keep in mind. Firstly, it's essential to know the type of plastic you're working with, as different plastics have varying melting points. Softer plastics like polyethylene require lower temperatures, around 300°F, while more robust plastics like ABS can withstand higher temperatures of up to 500°F. Always refer to the manufacturer's guidelines to avoid damaging the material.
When using a heat gun, start with a low temperature and gradually increase it until the plastic becomes pliable without burning. Basic heat guns have a few fixed heat settings, but more advanced models allow you to control the temperature with a dial. Hold the heat gun a few inches away from the plastic and move it slowly and evenly to ensure consistent heating. You can use sweeping motions to melt the entire piece of plastic evenly. Be patient and avoid applying too much direct heat too quickly, as this can cause burning or warping.
If you're using a hairdryer, you may encounter issues with quality and consistency. There can be problems with constant tearing, poor shrink, and temperature control. It's also important to note that hairdryers are not suitable for shrinking printed shrink film due to the inks in the film. For more precise and professional results, a heat gun is recommended.
Once the plastic is softened, you can reshape it as desired. If joining broken pieces, gently heat the edges and apply gentle pressure to create a strong bond. You can use a plastic welding rod of the same material for added strength. Allow the plastic to cool completely before handling, then trim any excess material or rough edges with a blade or sandpaper.
