4. Silicone Coating:

  • Once the plastic part has been molded but is still in the mold, a layer of silicone is applied to the desired areas. This can be done using various methods, including:a. Liquid Silicone Injection: Silicone is injected into the mold over the plastic component. It fills the designated areas, adheres to the plastic, and takes the desired shape.

    b. Silicone Dip Coating: The plastic component is dipped into a bath of liquid silicone. The silicone adheres to the surface and forms a coating when cured.

    c. Compression Molding: The silicone is placed on top of the plastic part in the mold, and the mold is closed, causing the silicone to bond with the plastic.

5. Curing:

  • The silicone-coated plastic component is then cured or vulcanized. This typically involves heating the mold to a specific temperature and holding it for a certain time. The curing process helps the silicone solidify and adhere to the plastic.

6. Cooling and Ejection:

  • After curing, the mold is cooled to solidify the silicone coating. The finished silicone-coated plastic part is then ejected from the mold.

7. Quality Inspection:

  • The silicone-coated plastic components are inspected for quality, including checking for any defects, adhesion issues, or other imperfections.

Silicone-coated plastic molding is used in various industries, such as consumer electronics, medical devices, automotive components, and more. The process allows for the combination of the durability and versatility of plastic with the desirable properties of silicone, such as enhanced grip, protection, or resistance to environmental factors.

LSR Molding: The Future of Manufacturing

Liquid Silicone Rubber (LSR) is a form of silicone rubber that is liquid at room temperature and can be molded into any shape using the Liquid Silicone Rubber Injection Molding Process. In this blog, we will explore the concept, process, advantages, and application fields of LSR injection molding.

Concept of Liquid Silicone Rubber Molding:

Liquid silicone rubber is a type of silicone rubber that is liquid at room temperature and can be injection molded into a variety of shapes and sizes. LSR is made from two components, a base material and a curing agent, which are mixed and then injected into a mold to create a solid product. The main advantage of LSR molding can produce high-precision parts.

Process of LSR Injection Molding Process:

1. Mold design and creation: The first step in the process is to design the mold that will be used to create the desired shape. The mold is created using CNC machining and is made of steel or aluminum. Make sure to withstand the high temperature of the LSR molding process.

2.Material Preparation: Depending on the desired properties of the product, the liquid silicone rubber is prepared by mixing it with a catalyst and a crosslinker.

3.Machine settings: The operator sets the injection volume, temperature, pressure, injection rate, and cycle time.

4.Injection molding: The process involves the use of an injection molding machine, which consists of a barrel and a plunger. The materials are first fed into the barrel. The material supply system is chilled and the mold is heated. The mold closes in cooperation with the machine’s injector, pump, and supply. The injection mechanism pushes the materials into the mold and cavities.

5.Curing: Once the mold is filled with silicone, the temperature of the mold is increased to accelerate the crosslinking process of the silicone rubber, causing the materials to change from a liquid to a solid state.

Shedding Light on Optical Silicone

Ultra Clear Optical Silicone:

Can silicone be used as an optical material? What is Optical Silicone? Optical Silicone is a specially formulated silicone material designed to transmit light with minimal distortion. In this blog, we will introduce you to the concept, benefits, and applications of optical silicones.

What is Optical Silicone？

Optical silicone is a type of silicone material that has been formulated to have excellent optical properties. It can transmit light very well while maintaining its clarity and transparency over time. Not only does it have the advantage of traditional optical materials such as glass or thermoplastic (PC, PMMA), but it can also be used in applications where traditional optical materials cannot meet the required optical specifications.

To improve the durability and transmission of lighting products, optical silicone can be a solution.

So what’s so special about optical silicone?  Next, I will introduce you to the advantages of optically clear silicone.

Benefits of Optically clear silicone:

Optical silicone is a highly durable material. Unlike thermoplastic, which can easily scratch or break, optical silicone is highly resistant to damage. Optically clear silicone can withstand extreme temperatures ( -40℃ to 250℃), harsh chemicals ( acid, alkali), and other environmental factors that can damage it. This makes it an ideal choice for applications where the material will be exposed to harsh conditions or frequent use.

High Refractive Index and Excellent Optical Clarity:

Optical silicone has a high refractive index. It means it bends light more effectively, resulting in brighter and more efficient lighting. Optically clear silicone also has excellent light transmission and it is a very transparent material. It allows for the maximum amount of light to pass through, creating brighter and more vibrant lighting.

Color Stability:

Optical Silicone is not easy to yellow during use. As can be seen in the chart below, optical silicone has excellent color stability and is not prone to yellowing in different control experiments. Optical silicone maintains its clarity and color stability even after years of use.
