What are the differences between rotational-molded and injection-molded plastic trash cans?

When choosing a plastic trash can, understanding the differences between rotational-molded and injection-molded options is crucial. Rotational-molded trash cans are created by heating plastic powder in a rotating mold, resulting in a seamless, durable product with uniform wall thickness. This method is ideal for large, heavy-duty bins, as it offers superior impact resistance and weatherproofing.

In contrast, injection-molded trash cans are made by injecting molten plastic into a fixed mold under high pressure. This process allows for intricate designs and thinner walls, making the bins lighter and more affordable. However, they may lack the durability of rotational-molded counterparts, especially in harsh environments.

Key differences include:

1. Durability: Rotational-molded bins are tougher and longer-lasting.

2. Cost: Injection-molded bins are cheaper but may need frequent replacement.

3. Weight: Rotational-molded bins are heavier, while injection-molded ones are lightweight.

4. Design Flexibility: Injection molding supports complex shapes, whereas rotational molding is better for simple, robust designs.

For outdoor or industrial use, rotational-molded trash cans are the better choice, while injection-molded bins suit budget-conscious indoor needs.
