Jamindo LSR Injection Molding Process

To maintain our position as a leading provider of liquid silicone rubber injection molding services and a business partner you can trust, Jamindo offers various services, including design support, pre-production prototypes, and pilot runs, as well as high precision, large-scale LSR parts and component production.

Step 1: Preparation of the mixture

Depending on the required qualities of the finished product, LSR typically comprises two components: pigment and additives (such as fillers). The mixture’s pieces are homogenized in this step and can be integrated with the temperature stabilization system for improved silicone temperature control (ambient temperature or silicone preheating).

Step 2: Mold Clamping

Silicone injection can be performed in a vacuum or under atmospheric pressure. The injection pressure used for the product being created and the silicone’s qualities, such as viscosity, affect the injection time. A clamping device closes the mold in the subsequent stage.

Step 3: Mold Curing

The curing stage is a critical step in processing silicone rubber, where the material transforms from a liquid to a solid state. Temperature and pressure increase inside the mold can be observed as a result of the exothermic effect of a curing reaction and high thermal expansion of silicone.

Шаг 4: Впрыск пластика

Once the pellets have been liquefied, the plastic will be infused into the form at a high weight. This can be where the magic happens, and your parts will begin to require shape.

Шаг 5: Охлаждение

Silicone rubber injection molding is the final step in the silicone rubber production process. It involves a series of steps, including moulding, demolding, cooling and final cooling in ambient circumstances.

Шаг 6: Выброс

Once the portion has cooled and solidified, it’ll be prepared to be catapulted from the form. Our machines are prepared with ejector pins that will thrust the portion out of the shape.

Our LSR Injection Molding Capabilities

Single-shot molding

Only one LSR material is used for injection molding items in this molding process.

2-Shot Injection Molding
Multi-shot molding

LSR is integrated with two or more polymers or a polymer plus substrate for more complicated components.
