What are the production processes of lsr injection molding?
The molding process begins by preheating the two halves of the mold to the correct temperature before injecting them with liquid silicone rubber injected at high pressure into the mold cavity.
Once filled, the material then cools for a period of time before the mold is opened.
Heating & Injection
Finished lsr molded parts are then ejected from the cavity and collected for further processing, including trimming, post-curing, painting, or assembly into final products.
In this lsr injection molding process, the lsr material is heated to create a liquid state and then injected into a pre-shaped mold.
The injection pressure of the mold is then used to shape the part and make sure that it cools correctly. The end result is a precise, detailed replica of the original design.
LSR Molding molding offers a cost-effective way to produce highly accurate molded parts with excellent heat, electrical, and chemical resistance in large volumes.
It also provides great flexibility for creating intricate shapes and can be used with a wide range of materials.
Silicone Injection Molding Methods
The process of lsr injection molding begins with the creation of a mold, which is a tool used to shape and form the product.
This can be done using a variety of methods, such as 3D printing, machining or casting. Once the mold is ready, liquid silicone rubber is injected into it under pressure.
Which industries could leverage liquid silicone injection molding?
Silicone injection molding is used in various industries, such as automotive, medical, consumer electronics, aerospace, food processing and much more due to its high durability and chemical resistance.
Silicone components for Electronics
Silicone components for Automobile
Silicone components for medical use
