How Much Does an Injection Mold Cost?
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.
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
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 $60,000–$100,000 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.
