Liquid Injection Moulding (LIM) is a process in which two components of silicone rubber are processed into a semi-finished product or end product. Both components are fed into the liquid injection-moulding machine in a 1-to-1 ratio by a pump system. Both components are then mixed within the system of pipes, together with a colorant or other additive if desired.
This mixture is permanently cooled throughout the process, after which the desired amount of material is injected into a heated mould via a (controlled) cold-channel system. This can be a single instance, prototyping, and/or small batch sizes, or multiple instances.
In addition, it is possible to manually create a few samples with a simple test mould. The 3D printing of samples is also an option.
The versatility of LIM is a result of the material properties of LSR. Silicone can maintain a high degree of heat and flame resistance, tensile strength, flexibility, hardness, and compression set. Depending on the chemical composition, these materials can also serve as insulators or conductors. LIM makes it possible to manufacture very advanced products and components!
