Ditch the Metal: Why Plastic Is the Upgrade You Didn’t Know You Needed

Still clinging to metal parts? It might be time for a breakup. With today’s advanced plastics—and super efficient processes like rotational molding and thermoforming—switching from metal to plastic isn’t just smart, it’s kind of a no-brainer.

At Redline Plastics, we help companies make the switch every day, and here’s why they never look back:

The Perks of Going Plastic

1. Lightweight = Less Work
Plastic parts are way lighter than metal. Easier to handle, cheaper to ship, and perfect for moving equipment or gear.
According to MIT, replacing metal with plastic in automotive applications can reduce weight by up to 50%, improving fuel efficiency and emissions.

2. Big Savings
Plastic often costs less to make, mold, and move. Fewer parts, less labor, less waste.
The American Chemistry Council reports significant cost savings in manufacturing due to plastic’s processability and lower production costs.

4. Zero Rust, Zero Fuss
No corrosion. No coating. Just durable, weatherproof parts that last.
NACE International, the corrosion society, lists corrosion resistance as a key benefit of plastics in harsh environments.

6. Built-In Style
Colors? Textures? Branding? Done right in the mold. No painting needed.
According to Plastics Industry Association, in-mold decorating cuts secondary costs and enhances durability.

⚙️ When It Makes Sense

  • Use rotomolding for big, hollow, or durable parts—like tanks, bins, or enclosures. Or we can get innovative and use rotomolding and our CNC cutting process to create all kinds of panels, shrouds or other custom parts.

  • Use thermoforming for sleek panels, trays, covers, and more! We specialize in heavy gauge vacuum forming material thicker than .060”

Bottom line?

Plastic parts can be lighter, cheaper, better looking, and just as tough. Let’s talk about converting your current product—you might love the results.
