Crucial Considerations When Calculating Plastic Injection Mold Costs
If you intend to calculate the cost of plastic injection molding, it helps to recognize the fact that the price stated on the quote is not the only important consideration. 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. Several parameters have a bearing on these two elements of your mold’s general costs.
Here are factors affecting the purchasing costs of an injection mold:
The Size and Design of Parts
A Beginners Guide To Molding
The creation of large components requires large molds, and ultimately higher material costs. Likewise, a complex mold design is required to cater to complex part design, which usually results in higher total costs. On the contrary, mold design requires less sophistication when the output is also less sophisticated in design, helping lower tool costs.
5 Key Takeaways on the Road to Dominating Molding
Plastic Type Selection
You may need to buy a more costly mold for use with certain types of plastics. For instance, higher tool costs are expected with material that’s unstable, corrosive, or has mineral, glass, carbon fiber, or other corrosive materials. This is also the case with plastics needing high tool temperatures. Residual maintenance expenses for the mold may be affected by these variables also.
Component Tolerance Strategy
When tight tolerance is needed for parts being output, extra machining steps will be needed. In the end, there will be higher costs for maintenance as well as manufacture.
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
Even cooling is necessary over the entire cavity impression, or in each cavity for multi-cavity equipment if you’re going for swift machine cycles. To accomplish this, excellent tooling design and superior build are necessary, both which contribute to increased tool machining costs, and maintenance costs in certain scenarios.
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. Nonetheless, take quality into account as you assess the cost of local vs. outsourced plastic injection molding. To be safe from the complications that lower-cost machines may have, it helps to reach a fair compromise as you carefully weigh cost, quality, and your exact needs.
Do you want to buy low cost injection molding? The total cost of the tool you purchase will be influenced by the variables above.
