Answer 1

Plastic bottles are made through injection molding using melted plastic, while aluminum bottles are made through extrusion using heated aluminum sheets. Plastic containers are lightweight and affordable, while aluminum bottles are lightweight, durable, and recyclable.

Step-by-step explanation:

Plastic Bottles:

Plastic bottles are made through a process called plastic molding. Here are the steps involved:

1. Raw material preparation: Plastic pellets, made from petroleum-based chemicals, are heated and melted to form a molten plastic.

2. Injection molding: The molten plastic is injected into a mold, where it takes the shape of a bottle. The mold is then cooled and the plastic solidifies.

3. Finishing touches: The bottle is removed from the mold, trimmed, and any necessary labels or caps are added.

Benefits of Plastic Containers:

• They are lightweight, making them easy to carry and transport.
• They are inexpensive to produce, making them affordable for consumers.

Aluminum Bottles:

Aluminum bottles are made through a process called extrusion. Here are the steps involved:

1. Metal preparation: Aluminum sheets are heated and rolled into coils.

2. Extrusion: The heated aluminum is forced through a die to create a cylindrical shape.

3. Welding and finishing: The cylindrical shape is cut to the desired length, welded at the seams, and any necessary labels or caps are added.

Benefits of Aluminum Bottles:

• They are lightweight and durable, making them ideal for outdoor activities.
• They are recyclable, reducing the environmental impact.

Similarities in Making Plastic and Aluminum Bottles:

• Both involve extrusion processes.

Differences in Making Plastic and Aluminum Bottles:

• Plastic bottles use plastic as the primary material, while aluminum bottles use aluminum.
• Plastic bottles are made through injection molding, while aluminum bottles are made through extrusion.
