by Nice Rapid | Nov 27,2023 | Silicone Molding

Silicone molding has been a cornerstone in the world of manufacturing, offering the ability to create flexible and durable parts, products, and prototypes with unmatched versatility. This manufacturing technique boasts a plethora of advantages over traditional methods such as injection molding, thermoforming, and even 3D printing. In this blog, we'll explore the exciting developments and innovations in silicone molding while also delving into the wide range of industries and applications that benefit from this technology.

The Evolution of Silicone Molding

Silicone molding though not new, remains at the forefront of innovation in manufacturing. Recent years have witnessed remarkable developments, expanding its capabilities and applications. Here are some notable advancements in silicone molding:

1. Liquid Silicone Rubber (LSR) Injection Molding

Liquid Silicone Rubber (LSR) injection molding is a process that combines the best of both worlds by taking advantage of and injection molding. LSR injection molding uses liquid silicone rubber, which is injected into a heated mold under high pressure. The rubber rapidly cures within the mold to create solid, precision-engineered parts. The benefits of LSR injection molding are substantial, including:

  • High-quality, consistent production: LSR injection molding produces parts with very tight tolerances and excellent surface finish.
  • Reduced material waste: LSR is a very efficient material, and little material is wasted in the molding process.
  • Shorter production times: LSR injection molding is a very fast process, which can lead to shorter production times and faster time to market.
  • Cost savings: LSR injection molding can be a cost-effective process, especially when compared to other methods of manufacturing precision parts.
