Difference Between LSR Injection Molding And Compression Molding

Difference Between LSR Injection Molding And Compression Molding

As a professional LSR injection molding manufacturer, Better would like to share the difference between LSR injection molding and Compression molding. There are four four aspects in their differences. We will give your more detailed explanation. First we gonna know what are Liquid injection molding and compression molding:

▼ Liquid Injection Molding

Liquid injection molding, LIM in short, uses liquid silicone rubber (LSR) or similar elastomeric material to manufacture wide ranges of products to demonstrate excellent durability and flexibility. Seals and sealing membranes, electrical and electronic components, such as connectors and cables, medical and sterile devices, kitchen goods, infant care products and other products are produced by LIM.

Due to its use of LSR, liquid injection molding relies on a more streamlined and consistent mechanical mixing process rather than a labor-intensive one (such as is used in compression molding). The closed-loop process employs a pump and mixing unit to mix and dispense the liquid material into a molding press. Once the curing stage is complete, the press opens and ejects the finished component, allowing it to be manually or robotically removed. Liquid injection molding is one of the most cost-effective and versatile manufacturing methods currently available. It is applied towards any industry or market, including: Aerospace and aviation, Automotive, Electronics, Food and beverage, Medical and dental, and etc..

▼ Compression Molding

Compression molding involves placing a thermosetting resin into a heated mold cavity and applying pressure to force it down and compress it in the mold. Material temperature and pressure levels are regulated throughout the process from dispensing to curing to facilitate precise part production.

Compression molding is highly flexible and versatile. It is suitable for producing parts of various sizes, thicknesses and complexities and addresses certain manufacturing challenges such as production operations requiring exotic materials, difficult-to-manage inserts or unique part shapes.

While compression molding is suitable for high-volume production, liquid injection molding offers faster processing with greater repeatability and consistency, requiring little labor. Compression molding offers faster production changeover times, cheaper tooling in some cases, lower upfront material costs and greater production flexibility.
