Simple plastic injection molds can cost anywhere between $3,000 and $6,000. The price for a large, more complex high-production, multi-cavity mold can cost upwards of $25,000 – $50,000 or more.
Although easy to state, there are a lot of details that go into the cost of injection molding. Here are some things to consider:
How Injection Molding Cost are Estimated?
The cost of plastic injection molding can differ based upon many factors:
- Size of the injection mold
- Complexity of the plastic part to be molded
- The mold type (if it’s going to be used for prototype parts, production, or longer production runs)
- Number of identical injection mold cavities (or a family mold with several cavities for related parts)
Additionally, the type of metal used to make a mold can affect cost. Aluminum is cheaper than steel, however, aluminum cannot be modified or repaired as easily as steel molds and in most cases aluminum molds cannot be repaired or modified at all. Steel molds are sometimes slightly more expensive, but they can last for longer production runs, can be easily modified/welded and reworked for changes in design or for repairs. This is why ICOMold uses prehardened-steel for our injection molding. By using steel, we save our customers time and money.
Types of Plastic and Effect on Cost
When it comes to the cost of injection molded plastic parts, the type of plastic resins also comes into play. Depending on what the part is designed to do, you may choose a plastic material that is less costly or very inexpensive. Some of the plastics characteristics that can affect cost are:
- High Impact
- High Gloss
- High Flow
- Fire Retardant
- High Heat
- Low Temperature
- UV Resistance
- Food Grade
Comparing Injection Molding Prices
A smart business owner will look to source several injection molding quotes from companies and manufacturers. Each mold manufacture may use a different approach so it’s important to know the details behind the quote. Although one may be cheaper, they be providing less than what you need. More expensive quotes may actually add in services you actually don’t need. So in the end, it all comes down to know the exact details of the project you need and finding a vendor that will provide with the level of service and quality product you are looking for. At ICOMold, we offer an online quote system for getting quotes for your custom plastic injection molding, CNC machining, or urethane casting project as quickly and easily as possible. There’s no software to download – just upload your CAD model to the online portal and select your options like part quantity, material and finish. It’s the world’s only 30-second injection molding quote system.
How to Lower Your Injection Molding Project Costs
There are several things you can do to help control and lower your costs when it comes to injection molding. Some of the more common items are:
Reduce unnecessary product features
- If budget is a concern, then keep your product features to a minimum. Too many features and functionality can increase costs significantly.
Eliminate cosmetic finishes and appearances
- Although they make the product look nice, certain design features may not be worth the extra costs.
Re-evaluate product part sizes
- If the part is big, so may be the price
- Depending on the product paying the price for overmolding may be worth it in the end
Injection Molding Costs Will Vary By Project
As mentioned previously, the small, simple, single cavity injection mold can cost as little as a couple thousand dollars. But a large, more complex high-production, multi-cavity mold can cost upwards of $25,000–$50,000 or more. Neither of these extremes is typical, of course, since the injection molds mentioned here are either very small and simple or very large and/or complex.
The typical injection mold can cost between $4,500 and $16,000.
