There are a few key components of any plastic injection molding process used to create any kind of plastic part or appliance, and the creation of the actual mold in question is one of the most important. The mold lays the foundation for the entire project, allowing for a heated liquid resin to be injected into it to fill its cavities and create the desired part – and as such, its creation is vital.

At EnviroTech Custom Injection Molders, we’re happy to offer the very best plastic injection molding services in the business, creating products for industries ranging from medical devices to agriculture, automotive, mining, energy and numerous other sectors. We walk our clients through the entire process of part manufacturing, including the all-important area of mold design and creation. Here are the key factors that our experts will be considering with your help as we design the mold for any product you order from us, plus why they’re important and what you might consider in each area.

Quantity Required

As you may have expected, one of the most important considerations when it comes to mold design is the number of parts you need to be created. Higher quantities may require more complex molds with greater durability, as they will need to withstand repeated use for extended periods of time.

For lower-volume projects, simpler molds might be more appropriate. In general, the larger your production run, the more intricate and durable the mold will need to be – but it’s also important to remember that lower volumes can mean higher cost per part due to the greater expense of designing and producing a complex mold.

Part Design

The design of your desired product is another key factor when it comes to mold creation. Complex parts with intricate designs will require a more sophisticated mold, including features such as side actions, threads, and undercuts. Our team will work closely with you to ensure that every aspect of your design is accounted for in the mold, resulting in a higher quality finished product.

Another key design-related area to consider is dimensionality, or the number of dimensions in your product. The more complex and multi-dimensional your part is, the more challenging it will be for us to create a mold that captures all its features accurately.

Material Selection

The type of material used for your product also plays a significant role in mold design. Different materials have different properties, such as shrinkage rates and flow characteristics, which must be accounted for in the mold design. We’ll work with you to select the best material for your project and ensure that the mold is optimized for its specific properties.

Which material is selected will also have a direct impact on the cost and production timeline, as some materials may require additional steps or considerations in the mold creation process.

Part Size

The size of your desired product is another important factor to consider when designing a mold. Larger parts may require larger, more complex molds, while smaller parts can often be produced with simpler molds. Our team will work with you to determine the best approach for your specific part size, taking into account factors such as part geometry and material selection.

Tooling Budget

Both in terms of mold material and the potential for multiple-unit production, your tooling budget is a crucial factor to consider when designing a mold. If you have a higher tooling budget, you’ll be able to include more features and details in the mold, resulting in a higher quality finished product. However, if your budget is more limited, we can work with you to find cost-effective solutions that still result in a functional and high-quality mold.

Thermoset or Thermoplastic?

While this is technically part of the material selection section we already covered, the choice between thermoset and thermoplastic materials is important enough to warrant its own mention. Thermoset plastics are more difficult to work with but offer superior durability and dimensional stability, while thermoplastics are easier to mold but may not have the same strength or resistance to heat. Our team will help you determine which type of material is best suited for your project and design the mold accordingly.

As you can see, there are numerous important factors to consider when designing a mold for plastic injection molding.
