  3. Cornstarch:
    • Dusting the mold with cornstarch can help prevent sticking. Make sure to tap out any excess to avoid altering the texture of your product.
  4. Chill the Mold:
    • Before using the mold, you can try placing it in the refrigerator or freezer for a short period. This can help solidify the fats used in greasing and reduce the chances of sticking.
  5. Non-Stick Cooking Sprays with Flour:
    • Some cooking sprays are specifically designed for baking and include flour in their formulation. These can provide an effective non-stick coating.
  6. Use a Release Agent:
    • There are commercial mold release agents available that are designed to prevent sticking. These are commonly used in industries like baking and casting.
  7. Silicone Mold Conditioner:
    • Some companies produce silicone mold conditioners or release agents that are designed specifically for silicone molds. These can be applied before each use.

    • Lyasilicone silicone molding

Injection molding of liquid silicone rubber (LSR)

liquid injection molding process

Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.

Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is required. Due to the thermosetting nature of the material, liquid silicone injection molding requires special treatment, such as intensive distributive mixing, while maintaining the material at a low temperature before it is pushed into the heated cavity and vulcanized.

Chemically, silicone rubber is a family of thermoset elastomers that have a backbone of alternating silicon and oxygen atoms and methyl or vinyl side groups. Silicone rubbers constitute about 30% of the silicone family, making them the largest group of that family. Silicone rubbers maintain their mechanical properties over a wide range of temperatures and the presence of methyl-groups in silicone rubbers makes these materials extremely hydrophobic, making them suitable for electrical surface insulations.[1]

Typical applications for liquid silicone rubber are products that require high precision such as seals, sealing membranes, electric connectors, multi-pin connectors, infant products where smooth surfaces are desired, such as bottle nipples, medical applications as well as kitchen goods such as baking pans, spatulas, etc. Often, silicone rubber is overmolded onto other parts made of different plastics. For example, a silicone button face might be overmolded onto a Nylon 6,6 housing.

In order for the liquid injection molding process to fully occur, several mechanical components must be in place. Typically, a molding machine requires a metered pumping device in conjunction with an injection unit—a dynamic or static mixer is attached. An integrated system can aid in precision and process efficiency. The critical components of a liquid injection molding machine include

Injectors. An injecting device is responsible for pressurizing the liquid silicone to aid in the injection of the material into the pumping section of the machine. Pressure and injection rate can be adjusted at the operator’s discretion.
