Common challenges and solutions

Uniform Results

The challenge

The silicone industry often faces challenges in achieving a high degree of homogeneity in silicone mixing processes due to inconsistencies from hand mixing, or bladed mixing. The varying viscosities and properties of silicone materials can make it difficult to uniformly disperse additives, fillers, and components. Inconsistent mixing can lead to product variations and performance failures.

The solution

FlackTek™ addresses the challenge of achieving homogeneous mixing by utilizing advanced bladeless mixing equipment and a dual asymmetric centrifuge. This innovative and non-invasive approach ensures rapid and thorough homogenization of silicone mixes. FlackTek™'s technology efficiently disperses additives, fillers, and components, resulting in a highly consistent and uniform mixture. This enhances product quality and performance in the silicone industry.

Air Entrapment

The challenge

The presence of air bubbles and voids in silicone mixes can lead to several issues such as inconsistent curing, compromised product integrity, and decreased performance. Traditional mixing methods often struggle to effectively eliminate air bubbles and voids, resulting in suboptimal silicone products.

The solution

To eliminate air bubbles and voids, FlackTek™ naturally degasses as it mixes, but also provides an option to incorporate vacuum mixing capabilities into its mixing. The vacuum feature effectively removes trapped air, ensuring a more reliable curing process and consistent quality of silicone products. By eliminating the presence of air bubbles and voids, FlackTek™ helps to produce high-quality, bubble-free silicone mixes.

Time Consuming

The challenge

Silicone mixing is often time-consuming and inefficient. Traditional methods can be labor-intensive, requiring extensive manual effort and lengthy mixing times,  both of which lead to varying results. This inefficiency hampers production throughput and overall manufacturing quality and productivity.

The solution

FlackTek™'s innovative bladeless mixing technology significantly reduces mixing time, but the reliability is just as much a time-saver as the actual speed the machine operates at. This time efficiency optimizes production processes and improves overall manufacturing productivity for silicone materials, can help speed up testing and R&D, and no-cleanup-required means you can move from one batch to the next in record time.

Frequently asked questions

Does FlackTek™ provide anything to improve the transfer process for silicone and difficult-to-transfer materials?

Products like the SpeedDispenser™ and SpeedDisk™, are specifically designed to streamline materials transfer. The SpeedDispenser™ allows direct mixing and dispensing, eliminating the need for separate equipment and minimizing material handling steps. The SpeedDisk™ enables efficient transfer from a cup to a syringe with minimal material loss, ideal for silicone and other challenging-to-transfer materials.

Is cleanup required after using FlackTek™ products for silicone mixing?

FlackTek™ products are designed to minimize cleanup efforts. The recommended mixing vessel is a cup with lid, which after use can be thrown away. With the SpeedDispenser™, you can mix directly in the dispensing unit, reducing the need for additional containers and minimizing cleanup. The SpeedDisk™ enables efficient transfer with minimal material loss, reducing the need for extensive cleanup procedures.

Do I have to remove bubbles and voids from silicone after mixing?

No - FlackTek™ addresses the issue of air bubbles and voids during the natural process of FlackTek-ing. Additionally, the optional vacuum mixing capabilities facilitate the absolute removal of air bubbles and voids. This results in a reliable curing process, ensuring consistent and high-quality silicone products.
