With rising material costs and labor expenses, manufacturers are looking to reduce spending wherever possible. That extends to their investment in rotational molding. If you’re a manufacturer, you may be wondering how to lower your rotational molding cost. Or, if you have an idea, you might be exploring ways to lower your initial investment. That’s why we’ve put together this guide. Here, we’re exploring factors that impact rotational molding cost and showing you how to manage them.
Material Costs
As mentioned above, materials are a big expense for manufacturers. In the rotomolding space, costs will depend on the type of plastic resin you choose to use. Standard resins will be more affordable, while specialty resins will be more expensive. These specialty resins will usually have some characteristics like increased durability or chemical resistance. Additionally, additives like UV stabilizers, flame retardants, anti-static agents, and colorants can increase costs.
Other outside factors may also contribute to increased material costs. Global supply chain disruptions and fluctuating market demands influence these expenses. Additionally, if your manufacturing partner uses materials inefficiently, this will quickly increase costs.
So, how do you manage these costs? Ask your manufacturer if they can negotiate bulk purchasing agreements with suppliers, as this can keep pricing stable. Additionally, ask about material testing and process optimization. This can help reduce excess resin use. And, incorporating recycled materials can lower overall expenses.
Mold Costs
While rotational molds are less expensive than some other processes, they still represent a significant upfront investment. Mold material and complexity are the biggest factors that impact costs. Aluminum will be a more affordable material option, but it lacks the durability of steel. On the other hand, steel molds will be more expensive. But, they are more durable and better suited for long production runs. Simpler mold designs will be more affordable, whereas more intricate molds require more time and resources to produce.
How do you manage mold costs? If you have a lower-volume production, aluminum molds will be more cost-effective. And, working with an experienced manufacturer with extensive engineering expertise can help you optimize mold design.
Energy Consumption
Finally, energy consumption is a major factor in rotational molding costs. Inefficient energy use can lead to higher operating expenses. This might include energy used to heat the molds, maintain temperature control, and cool systems.
One way to reduce energy costs is to partner with a manufacturer that uses advanced molding technology, like the Leonardo SMART Molding Machine. This system has been shown to reduce energy consumption by 35%. Want to learn more? Read our in-depth blog here.
