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 essential to include the buying price as well as lasting expenses that will be incurred once you’ve started using the tool and keep occurring over the mold’s entire life. Many different factors are responsible for these two components of your mold’s total costs.
These are the variables that can determine the quoted price of an injection mold:
The Size and Design of Parts
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 contrary, mold design requires less sophistication when the output is also less sophisticated in design, helping lower tool costs.
Plastic Type Selection
You may need to buy a more costly mold for use with certain types of plastics. For example, plastic that’s volatile, corrosive or has abrasive components like mineral, glass, or carbon fiber may lead to higher tool costs. This also holds in case of materials requiring high mold temperatures. Such factors could also affect long-term maintenance costs of the tool.
Component Tolerance Strategy
When tight tolerance is needed for parts being output, extra machining steps will be needed. The costs of maintenance on top of manufacture will consequently increase.
If you’re buying your mold for high-volume projects (in terms of hours as opposed to number of parts), the tool has to be of high quality to offer reliable service, which certainly will increase its cost. Likewise, expect higher costs of manufacture for a tool with a higher number of cavities.
Cycle Time Needs
In case quick machine cycles are required, the whole cavity impression, as well as every cavity in multi-cavity machines, requires uniform cooling. 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 cost and quality you can get in your plastic injection mold depends on where it’s manufactured. 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 steer clear of the issues associated with some lower-cost molds, you should strike a fair balance when it comes to careful consideration cost, quality, and your particular requirements prior to making the ultimate choice.
