At least to some degree, asking what plastic injection molds cost is a lot like asking “How much is a car?”. Will your mold be a Pinto or a Porsche?
The determining factors in the cost of your mold are a combination of the part size, complexity, material, and anticipated quantities. For instance, if you wanted 1,000 washers per year, we would recommend a single cavity mold, meaning it makes one washer per machine cycle. In that case the mold would probably be $1,000-2,000.
On the other hand, if you are going to need 100,000 xbox controllers every month, we would build a 12 cavity hardened “family” mold which made four Fronts, four Backs, and four Button Trees every cycle, and you’d better have $60-$80,000 or more to invest.
Of course these examples are extreme, but it illustrates the range of costs to anticipate. Your particular part will most likely fall somewhere in between that, and the molds that Rex Plastics builds average around $12,000.
Material selection is another consideration in determining what plastic injection molds cost. If your product requires a fiberglass filled material for instance, it will most likely need a mold made from hardened tool steel due to the wear those materials cause when being injected under high pressure.
If you have a target price established for your parts, it will be helpful to let your mold builder know that, because they can design the mold with that in mind, and plan for the right number of cavities to achieve that price. The more cavities (or parts made per cycle), the less expensive the parts will be, also allowing for higher output.
While you don’t need to know every detail about the types of molds available, it’s always a good idea to come prepared. Supplying the basics to your mold builder will help them build the best tool for your project. It’s also recommended that you find a mold maker who also has production capabilities. The company running the production won’t want to build an inadequate mold because they know they have to use it!
Whatever your project requires, one thing Rex Plastics won’t do is suggest you invest in a Ferrari when all you need is a Fiat!From Website
