How to choose the right mold material
While producing plastic components in injection molding, the final product's quality, durability, and cost-effectiveness are influenced by the selection of the mold material. At JSJM Technology, we appreciate that choosing the right mold material in line with your project specifications is paramount. This article tries to delve into some of the factors that affect the choice of a mold material and the mold material advantages.
Defining the Scope of Your Project
Prior to exploring the details of mold materials, it is important to evaluate the requirements of the project. Factors including but not limited to, mold part configurations, quantity to be produced, the type of surface finishing, and how the molded part will be utilized are crucial when deciding on the concept. To illustrate, if a metal fashioning is needed in high amount then harder and more wear-resistant material should be used so that molds are strong enough and parts would be produced with great constant quality.
Common Mold Materials
Steel Mold Materials
Due to its remarkable toughness and wear resistance, steel is one of the most widely used materials in the manufacture of molds. Tooling steel and pre-hardened steel are two examples that afford different costs and performance. Tooling steel is appropriate for mass production between five and six thousand repetitions, while pre- hardened steel, being cheaper, is used mostly in the low-volume runs or prototype runs due to its economical cost and quicker machining time.
Aluminum Mold Materials:
Aluminum molds are light in weight and cool faster so cycle times can be reduced which in turn can yield higher outputs. Used in cases of medium volume production runs and quick reaction time is of utmost importance. However, in those cases steel molds may be the suitable option since aluminum may be damaged too quickly.
Composites:
Materials such as graphite as well as ceramic filled polymer are currently taking the market by storm due to their unique properties as well as efficiency which can aid for specialized areas where traditional metals would not be as suitable g for optimal output.
Factors That Affect the Choice of Mold Material
Design Complexity and Finishing of Products
When it comes to the surface finish and complexity of a part, the type of mold material that is to be used can be determined. Certain mold material may require sharp edges and intricate features to be maintained over time if the design is intricate or detailed. Likewise, if a design requires a polished surface, a mold material that gives a sphrical appearance might be required.
Expected Production Count
Another consideration while selecting a mold material is the expected production count, especially for bulk orders. A great deal of structural integrity is required for high volumes to ensure that usage does not lead to excessive damage because this in turn affects the quality or integrity of the parts being manufactured. On the other hand, for lower volume and prototype runs, the cost and delay in time of production are deemed more important than durability.
Expense Considerations
Last but not the least, the expense on the mold material should be accounted for. There are materials that are of better quality and are more durable but they tend to be on the pricier side because of the capital needed whereas cheaper materials prove more useful for projects that require a mold for a shorter timeframe.
Conclusion
Selecting mold material is an intricate decision with many parameters to consider. At JSJM Technology we use our knowledge in mold design and manufacturing to guide the clients through these choices easily. By defining the project scope, analyzing available mold materials, part geometries, estimated production numbers and costs an efficient mold material for the wielding will be chosen. As such, the relevant plastic components are manufactured in a manner which is both efficient and economically viable, while at the same time ensuring that they adhere to the required quality standard.
