I'm proposed a way I'd synthesize plastic...polyethylene to shape into a pipe

PROBLEM: not sure how or what I would use to make a mold or best method to produce a PIPE

not sure what a mold should look like to produce a hollow object like a pipe. OR what material I can use around the house to make a good mold.

I saw silicon but I don't think they have silicon in the shape of a pipe...

HELP!!

Thanks

note: I need to find a mold that can be used at home..not industrial scale

b/c presumably I'm a "poor college student" according to the HWK Q that asks us to create this pipe in the first place.

To synthesize plastic polyethylene and shape it into a pipe, you will first need to gather the necessary materials and tools. Here is a step-by-step guide explaining how you can create a mold and produce a pipe:

1. Materials Needed:
- Polyethylene plastic pellets or resin.
- A pipe-shaped object to serve as a model or template.
- High-temperature resistant silicone or another suitable mold-making material.
- A container or box to hold the mold material.
- Release agent (such as petroleum jelly or mold release spray) to prevent sticking.

2. Creating the Mold:
- Take the pipe-shaped object and securely attach it to the bottom of the container or box. Make sure it is centered and in the desired position.
- Prepare the mold-making material according to the manufacturer's instructions. If using silicone, mix the two components thoroughly.
- Pour the mixed mold-making material over the pipe-shaped object in the container. Make sure to cover it completely and smoothly to capture all details.
- Allow the mold-making material to cure fully as per the manufacturer's instructions. This may take several hours or more depending on the specific product.

3. Removing the Mold:
- Once the mold has fully cured, gently remove it from the container or box.
- Carefully detach the pipe-shaped object from the mold. You can use a releasing agent to help with the separation.

4. Preparing for Plastic Synthesis:
- Now that you have the mold, clean it thoroughly to ensure there is no residue or release agent left, which could affect the quality of the final plastic pipe.

5. Synthesizing the Plastic:
- Follow the proper instructions for melting and processing the polyethylene plastic. Generally, this involves heating the plastic pellets or resin to their melting point in a suitable melting apparatus (such as a melting pot or extruder).
- Once the plastic is melted, carefully pour it into the mold. Be cautious not to overflow or leave air bubbles.

6. Cooling and Finalizing:
- Allow the plastic to fully cool and solidify. The cooling process may take several hours or overnight, depending on the thickness of the pipe.

7. Removing the Pipe:
- Once the plastic has completely solidified, gently remove the pipe from the mold by carefully flexing or demolding it. If necessary, use a release agent or light tapping to help with the demolding process.

It's important to note that creating a high-quality pipe requires precise temperature control during the plastic synthesis process and proper mold design to ensure uniform thickness and structural integrity. It may be helpful to research specific techniques for extrusion or injection molding to enhance your understanding of the process.

Additionally, if you don't have access to suitable mold-making materials or equipment at home, you may need to consider other alternatives such as purchasing a pre-made pipe mold or exploring local resources like maker spaces or fabrication shops that offer mold-making services.
