Liquid Silicone Rubber Molding Process

Injection molding of liquid silicone rubber lsr is a process to produce pliable durable parts in high volume.

Liquid silicone rubber molding process.

Liquid silicone rubber is a high purity platinum cured silicone with low compression set great stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts where high quality is a must. Liquid silicone rubber molding our liquid silicone rubber molding process produces custom prototypes and end use production parts in 15 days or less. Depending on the cross section of the molded component the cure cycle for lim can take from 30 seconds up to 2 minutes with an average cure time of 35 to 50 seconds. Also known as lsr silicone molding liquid silicone rubber this is a liquid injection molding process where a high viscosity liquid comes in two parts part a and part b is loaded into the molding machine.

Here are the primary steps involved in the liquid silicone rubber injection molding process. Liquid silicone rubber injection molding is a thermoset process that cools the material delivery system while heating the mold tool to cure silicone material into parts. Due to the thermosetting nature of the material liquid silicone injection molding requires special treatment such as intensive distributive mixing while. The molder can program and customize the automated injection molding machine and have.

Liquid silicone rubber is widely used in tod. The uncured liquid silicone starts in two containers compound a and compound b which connects to the pumping system. Injection molding of liquid silicone rubber lsr is a process used to produce pliable durable parts in high volumes. An injector a metering unit a supply drum a mixer a nozzle and a mold clamp among others.

Unlike the standard reaction injection molding process which relies on pressurized impingement mixing liquid injection molding uses a mechanical mixing process that focuses mainly on liquid silicone rubber lsr and similar elastomeric materials. The silicone rubber injection molding process. Liquid injection molding lim is an industrial fabrication process that molds materials into a broad range of components and products. The process of liquid injection molding lim of liquid silicone rubber has a cost advantage over compression molding of gum based silicone which is due to the cure cycle.

We use aluminum molds that offer cost efficient tooling and accelerated manufacturing cycles and stock various grades and durometers of lsr materials. The machine mixes the two parts just before it is injected into the mold cavity where a chemical reaction causes it to cure very quickly.
