LSR Molding

LSR Molding

Liquid Silicone Rubber(LSR) has been in high demand since its development in these days. That's hardly surprising given its sical properties and the variety of applications it may serve. LSR is long-lasting, flexible, stable, and versatile. Customers appreciate the dependability and quality that our company consistently provides, so it's no wonder that our influence in the LSR sector is expanding as well.

Injection moulding of liquid silicone rubber is a process that involves mixing two-part Liquid Silicone Rubber material, then curing it thermally in a mold using a platinum catalyst to produce silicone rubber parts and products.

Liquid Silicone Rubber Molding is quite similar to the traditional process of plastic injection molding. However, the primary distinction between the two methods is that the conveying system for materials is cooled while the mold is heated.

CN: The Perfecting LSR Process

STEP1

Put the base-forming silicone and the platinum catalyst parts of the Liquid Silicone Rubber compounds A & B into the pumping system using the supply drums. Additionally, there is a separate container for the additives and color pigments.

STEP2

Mix the two Liquid Silicone Rubber, base-forming silicone and platinum catalyst by using the metering unit. Make sure that the two Liquid Silicone Rubber are kept at a consistent ratio of 1:1 while being transported simultaneously.

STEP3

Set up and start machine, Inject these mixed compounds into the mold cavity via nozzle and cold runner system.

STEP4

Once the silicone rubber products have undergone vulcanization and solidification, they can be removed from the mold either automatically or manually.

STEP5

The product will be post-processed and inspected.

CRITICAL ADVANTAGES OF

LSR Molding

Advantages of LSR Molding

LSR's versatility and impressive properties make it a valuable material for a wide range of applications. From everyday gadgets to cutting-edge medical devices, LSR is shaping the future in many ways.

Crystal Clear and Tough: LSR boasts exnt transparency, allowing intricate details to shine through. It's also tear-resistant, meaning it can handle wear and tear without breaking easily. It even resists turning yellow over time, keeping your products looking fresh.

Temperature Hero: This material is truly extreme temperature resistant, functioning well even in extreme temperatures ranging from -60°C to 250°C. So, whether you're dealing with icy winters or scorching summers, LSR can handle it.

Durable and Dependable: Strong, flexible, and stable, LSR offers long-lasting performance. It can even act as an insulator, preserving both electrical and thermal conductivity when needed.

Automotive Applications: In the automotive world, LSR shines due to its heat resistance, ability to compress without losing shape, and exnt resistance to chemicals. It's commonly used in sensor covers, seals, and even interior components.

Beyond Cars: LSR's chemical resistance and ability to withstand extreme temperatures make it popular in consumer electronics too. You'll find it in things like remote control buttons, cases, and even smartwatch bands. The growing popularity of wearable tech is expected to further boost the demand for LSR in this industry.

Medical Marvel: Because LSR is highly inert, biocompatible, and hypoallergenic, it's safe for use in medical devices like prosthetics and even artificial organs. However, it's important to note that it can degrade in highly acidic environments.

#FAQS

FAQ OF Liquid Silicone Rubber Molding



What is Liquid Silicone Rubber?



Liquid Silicone Rubber is an organic silicone material that is transparent, non-esistant, highly resilient and flexible once it has set. When it undergoes sulfurization, it exhibits low viscosity, quick curing, shear thinning, and a high coefficient of thermal expansion.

Liquid Silicone Rubber is a two-component material that has high transparency, strength and tear resistance. It can be processed through liquid silicone injection molding processes.

The Characteristics of LSR



Biocompatibility: After extensive experiments, it has been found that LSR is highly compatible with human tissues and fluids. In contrast to other elastomers, LSR is less prone to bacterial growth and does not cause contamination or corrosion of other materials.

Chemical Resistance: LSR can withstand water, oxidation, and certain chemical solutions like acids and bases.

Temperature Resistance: Compared to other elastomers, LSR can tolerate a variety of high/low temperature restrictions.

Mechanical Properties: The LSR material has great stretchability, strong resistance to tearing and pulling, and remarkable flexibility. Its hardness can range from 5 to 80 Shore A.

Electrical Properties: LSR has great insulation properties and is a great choice for many electrical applications. Silicone can withstand both higher and lower temperatures compared to traditional insulation.

Transparency and Pigmentation: LSR has a natural transparency that allows for the production of colorful and customizable molded products.
