What are the liquid silicone molding processes?

The liquid silicone molding process mainly includes the following types:

1. Liquid Injection Molding (LIM)
Liquid injection molding is a process of solidifying liquid silicone by injecting it into a closed mold. This process is suitable for mass production of complex shaped silicone products.

characteristic:
Efficient production speed
Accurate product dimensions and details
Suitable for large-scale production

2. Compression Molding
Pressure injection molding is the process of placing liquid silicone in an open mold and solidifying it through heating and pressure. This process is suitable for small to medium batch production.
characteristic:
Simple process, suitable for products of different shapes
Low equipment cost
Slow production speed, suitable for small and medium-sized batch production

3. Transfer Molding
Transfer molding is the process of injecting liquid silicone into the mold cavity, applying pressure to fill the entire mold, and then heating and solidifying it. This process is suitable for producing products with complex shapes and multi cavity molds.

characteristic:
Suitable for complex shapes and multi cavity molds
Can reduce waste and improve material utilization
Moderate production efficiency

4. Casting
Pouring molding is the process of pouring liquid silicone directly into an open mold and solidifying it through natural curing or heating. This process is suitable for small-scale production and prototype production.
characteristic:
Simple process, suitable for prototype and small batch production
Low mold cost
Slow production speed

5. In Mold Injection Molding
In mold injection molding is the process of injecting liquid silicone into a mold and combining it with other materials (such as plastic and metal) for molding. This process is suitable for producing composite material products.
characteristic:
Can achieve the combination of different materials
Suitable for producing composite material products
High production efficiency

6. Dispensing Molding
Dropping molding is the process of solidifying liquid silicone by dropping it into a mold through a dispensing device. This process is suitable for producing small batches, complex shapes, and finely structured products.

characteristic:
Suitable for small batch production and fine structure
Can achieve high-precision material control
Slow production speed
Each liquid silicone molding process has its unique advantages and applicable scenarios. Choosing the appropriate process based on specific product requirements can effectively improve production efficiency and product quality.
