Crucial Considerations When Calculating Plastic Injection Mold Costs
If you wish to calculate the cost of plastic injection molding, it’s essential to keep in mind that a lot more than just the price mentioned on the quote matters. It’s important to consider the purchase price along with residual costs that will take effect after you’ve started using the mold and continue to occur throughout the life of the tool. Numerous variables account for the two aspects of your tool’s overall costs.
These are the variables that can determine the quoted price of an injection mold:
Part Size and Design
Large molds are needed to create larger parts, leading to greater material costs. In the same vein, an elaborate part design calls for an elaborate tool design, which basically keeps the costs higher. On the other hand, parts with simple design requirements go with less complexity in design of the mold, leading to a lower price for the tool.
Plastic Type Selection
Use of some types of plastics may require the purchase of a more expensive mold. For example, material that’s volatile, corrosive, or features abrasive substances such as mineral, glass, or carbon fiber may increase mold costs. This also holds in case of materials requiring high mold temperatures. Additionally, maintenance costs for the mold may be affected by the parameters in the long run.
Component Tolerance Strategy
If tight tolerance is required for parts being produced, there’s the need for additional mold manufacturing steps. In the end, there will be higher costs for maintenance as well as manufacture.
In case you’re acquiring it for high-throughput projects (in the sense of hours, rather than number of components), you’ll require an excellent quality mold to deliver consistent service, which results in higher costs, certainly. A mold with a higher number of cavities is also linked to higher manufacturing costs.
Cycle Time Preferences
When fast tool cycles are preferred, there’s need for consistent cooling throughout the entire cavity impression, or in each cavity in the case of multi-cavity molds. For this to work, superior tooling and high precision configuration are important, both of which play a role in increased mold construction costs as well as maintenance costs in particular cases.
Country of Manufacture
The country where your plastic injection mold was made can determine the costs and quality you may expect. For example, cost of injection molding China may be lower compared with other markets. While you look into the cost of local against overseas plastic injection molding, prioritize quality, though. To avoid problems that may come with some cheaper molds, you need to balance well considerations such as costs, quality, and your specific needs before making a final decision.
