Dear friends,this is YJC Polymer,embarking on a journey to demystify the realm of molded silicone keypads – because, let’s face it, who doesn’t secretly want to be a keypad connoisseur? Get ready to dive into the intriguing universe where every press is a tactile symphony. Welcome to the blog where we unravel the secrets behind “Gaining Insight into the Materials Employed in Molded Silicone Keypads.” It’s not just about buttons; it’s about the tactile magic beneath our fingertips. The following is the brief introduction.
Understanding the composition of your molded silicone keypads is a crucial aspect of our client education process. We aim to provide you with a comprehensive understanding of your product’s materials to enhance your grasp of its functionality.
Our silicone injection molding process, known as Liquid Injection Molding (LIM), is a fascinating procedure with key highlights:
- Liquid injection molding relies on liquid silicone rubber (LSR) and various elastomeric materials to create durable and flexible products.
- The range of products includes membranes, seals, electrical connectors, kitchen goods, and medical products.
- LIM employs a mechanical mixing process, ensuring a high level of consistency, surpassing labor-intensive methods like compression molding.
- The LIM process incorporates a variety of materials, encompassing fibers, silicones, acrylics, and additives.
Silicone rubber stands out as an optimal material for molding keypads:
We prioritize the use of premium materials in crafting our molded silicone keypads, with a focus on the distinct advantages offered by silicone. Its low viscosity ensures seamless flow into hot molds at low pressures, tailored to the mold’s thickness and production cycle requirements. Factors like the parting line and vent track depth are meticulously considered for optimal fill before the silicone cures.
In LSR molding, the unique property of silicone rubber to shrink when cool is strategically factored into mold planning. This allows for precise control over the final product’s finish, offering options for a clean, matte appearance or a polished, glossy texture.
Our closed-loop system utilizes specialized machines, ensuring precise mixing and measurement of liquid silicone rubber (LSR). This approach minimizes contamination risk and enhances product precision and repeatability, crucial elements in the manufacturing process.
Advantages of Opting for Liquid Silicone Rubber：
We prefer utilizing Liquid Silicone Rubber for its exceptional ability to efficiently fill molds and undergo rapid curing compared to gum stock or high-consistency silicone rubber (HCR).
LSR excels in intricate mold designs, leading to shorter cycle times and enhanced heat resistance. The curing takes place within the mold, minimizing waste and eliminating the need for post-molding trimming. The choice of materials in molded silicone keypads offers numerous advantages, underscoring the importance of LSR in achieving optimal results.
