You have a product idea. You know plastic molding can bring it to life. But one question keeps coming up: Can I actually afford this?
The truth is, plastic molding costs vary a lot. A mold can run anywhere from $1,000 to over $100,000. That range confuses many first-time buyers. But once you understand what drives the price, budgeting gets much easier.
This guide breaks down plastic molding costs in plain terms. You’ll learn exactly what affects price and how to plan your budget. We’ll cover the main cost factors. We’ll explain when molding makes financial sense. And we’ll share ways to keep your project affordable.
Plastic molding costs depend on your project. For small runs, it can seem expensive. That’s because mold creation costs more upfront. But for large runs, the cost per part drops fast. It often falls to just cents each.
Main cost factors include:
For high-volume production, plastic molding is one of the most cost-effective methods available.
The upfront mold cost surprises most first-time buyers. Tooling is a big investment before a single part gets made. That sticker shock is real. But it tells only part of the story.
Here’s what many people miss: you pay for the mold once. Then it makes thousands of parts. The cost spreads across every piece produced. A $10,000 mold making 10,000 parts adds just $1 to each unit.
Compare that to 3D printing. There’s no tooling fee. But each part costs the same whether you make one or one thousand. At low volumes, 3D printing wins. At high volumes, molding pulls ahead fast.
We see this often at Freeform Polymers. A client gets their first quote and pauses at the tooling line. Then they see the per-part price at volume. The math clicks. Plastic molding rewards scale like few other methods can.
Understanding where your money goes helps you plan better. Four main factors shape your final price.
Mold and Tooling Costs
This is the biggest line item. Simple aluminum molds start around $1,000 to $3,000. Complex steel molds with multiple cavities can exceed $100,000. The mold’s material, size, and detail level all affect price. According to Protolabs, one of the easiest ways to reduce per-piece cost is by increasing part quantity, since tooling costs amortize over more parts.
If you need a custom mold built to your specs, our plastic injection mold making team can help design and manufacture tooling tailored to your production needs.
Material Costs
The plastic you choose matters. Commodity plastics like polypropylene and polyethylene cost less per pound. Engineering plastics like nylon cost more. High-performance plastics like PEEK can run $60 to $80 per pound or higher. Your part’s function determines which material fits best.
Machine and Production Costs
Press size, cycle time, and labor rates add up. Larger parts need bigger machines. Longer cycle times mean more run time. These factors set the hourly production cost.
Secondary Operations
Some parts need extra work after molding. Assembly, surface finishing, or pad printing adds to the final price. Plan for these if your design requires them.
| Cost Factor | Typical Range |
| Mold/Tooling | $1,000 – $100,000+ |
| Material (commodity) | $1 – $5 per pound |
| Material (engineering) | $5 – $25 per pound |
| Material (high-performance) | $60+ per pound |
| Production | $50 – $200 per hour |
| Secondary Ops | Varies by service |
Volume is the key question. The more parts you need, the more molding makes sense.
Here’s a simple way to think about it:
The breakeven point for simple molds typically falls between 500 and 1,000 parts. After that, each additional part costs very little to produce.
We worked with a client making 5,000 phone case parts. Their 3D printed prototypes cost about $8 each. After switching to injection molding, their per-unit cost dropped to $0.45. The mold paid for itself within the first production run.
You have more control over price than you might think. Small choices add up to big savings.
One example sticks with us. A client came to our North Logan shop with a part design that needed a complex mold. Our team suggested a small radius change on one corner. That single tweak saved them $3,000 in tooling costs. The part worked just as well.
Getting a solid quote starts with good preparation. The more details you share, the more accurate your pricing will be.

Questions to ask your molder:
When comparing quotes, look beyond the bottom line. The cheapest mold isn’t always the best value. A well-built tool lasts longer and runs faster. That saves money over thousands of cycles.
