Float above the rest: Replace potting with Low Pressure Overmolding!

Low Pressure Molding:
The Better Alternative for Circuit Board Potting

While traditional potting has long provided a standard solution for circuit protection, Low Pressure Molding (LPM) offers a more advanced, efficient and environmentally friendly alternative. The use of LPM significantly reduces material consumption and weight while improving the protection and design flexibility of electronic components. Find out why more and more industries are switching to this innovative technology.

Low Pressure Molding Compared
to Circuit Board Potting

Low Pressure Molding and traditional circuit board potting differ significantly in several key aspects. Low Pressure Molding offers a streamlined, environmentally friendly approach that reduces overall material use and weight, enhancing the sustainability of manufacturing processes. It provides superior protection and flexibility in design, making it an advantageous choice for modern electronic applications. These features contrast with the heavier, often more cumbersome traditional potting techniques, which may also involve more complex and less eco-friendly materials and processes.

FAQ
Low Pressure Molding and Traditional Potting

Embracing new technologies often raises questions. Wondering about the effectiveness or specific aspects of Low Pressure Molding? We’ve addressed the most common inquiries from our customers in our FAQ section to clarify any uncertainties.

How does Low Pressure Molding impact the total operational costs compared to traditional potting?

Low Pressure Molding typically reduces operational costs by lowering cycle times, using less material, and reducing waste. Additionally, the simplified process reduces labor costs and the need for post-processing steps like machining or housing installation, which further lowers overall expenses.

Can existing designs for traditional potting be easily converted to Low Pressure Molding?

While many designs can be adapted to LPM, some may require modifications to accommodate the lower pressures and temperatures used in the LPM process. Design considerations often include the integration of proper venting and the suitability of the substrate material to bond with LPM resins.

Can Low Pressure Molding provide the same level of component protection as traditional potting?

Yes, Low Pressure Molding can provide equal or superior protection against environmental factors such as moisture, dust, and impact. The materials used in LPM form a tight seal around components, which can be more effective in protecting delicate electronics compared to traditional potting.

Is the setup process for Low Pressure Molding more complex than that for traditional potting?

Although the initial setup for LPM, including mold design and machine calibration, can be more involved, the overall process becomes much more streamlined and efficient once these initial steps are completed. This contrasts with traditional potting, which often remains labor-intensive and time-consuming throughout.

How does the cost-effectiveness of Low Pressure Molding compare to traditional potting?

Initially, LPM may require a higher investment in terms of equipment and mold setup. However, the ongoing costs are generally lower due to reduced material usage, faster cycle times, and minimal labor requirements. Over time, these factors make LPM a more cost-effective solution compared to traditional potting.

What are the typical industries that are transitioning from traditional potting to Low Pressure Molding?

Industries such as automotive, consumer electronics, medical devices, and telecommunications are increasingly adopting LPM due to its superior protection, design flexibility, and environmental benefits.
