Benefits of liquid silicone rubber coated basis materials?
Liquid silicone rubber encapsulation molding is a cost-effective and versatile process used by manufacturers in many industries and applications. From liquid silicone rubber coated molding handle to complex electronic components, the advantages of silicone rubber coated molding are as follows.

1. Save cost and time

By directly molding silicone rubber onto metal or plastic substrates, you will save the cost and time required to manually assemble complex parts. This can significantly reduce manufacturing costs and turnaround time, enabling you to bring products to market more economically.

2. Design flexibility

LSR/thermoplastic injection molding is well suited to meet the complex design requirements of the automotive and medical industries. Silicone coating molding can produce waterproof, airtight, impact resistant and vibration resistant parts.

3. Quality control

LSR/plastic injection molding process has high tolerance and strict quality control, and is suitable for any application requiring precision. SIMTEC can produce ultra molded silicone components that meet your exact specifications, including equipment that needs to be manufactured in Grade VII or VIII cleanrooms.

With the development of organic silicone rubber industry and the continuous upgrading of product technology level and process requirements, the processing and molding process of liquid silicone rubber coating has become the mainstream processing method of silicone rubber product production. If you want high quality liquid silicone rubber products, there is no defect when you choose liquid silicone rubber injection processing, so the development trend of liquid silicone rubber processing technology is paid attention to. With the maturity of the process, the raw materials for the production of liquid silicone rubber have certain limitations. Is the technology of high hardness liquid silicone rubber mature?

Generally, when the liquid silicone rubber raw material exceeds 50 degrees, the processing difficulty of the product will increase. Due to the difference between liquid silicone rubber molding and solid molding, the raw materials are in the form of water paste. When the hardness increases, mixing and preparation will be more difficult. With the increase of hardness, the tear resistance of the material will also decrease. The higher the hardness, the greater the possibility of product fracture and damage.

Many products use high hardness liquid sealing silicone. At present, liquid silicone rubber products are more commonly used in our life, and it has advantages in performance and feel. However, many silicon plants are reluctant to use liquid silicone rubber materials with high hardness, because the higher the hardness of raw materials, the slower the feeding speed in the mold, the production and processing will seriously affect the efficiency and mold loss, and it is easy to generate high interest rates for non-performing products.

At present, solid state processing technology has broken through the requirement of 90 degree hardness. As the technology matures, it is likely to break through the hardness of 100 degrees or even higher in the future. However, when the technology of using high hardness silicone rubber materials in the production process of liquid silicone rubber is not yet mature, it is necessary to ensure the fluidity and high toughness of the materials, as well as the vulcanization molding time and fluidity of raw materials without any additives and crosslinking agents. The materials are always limited to low temperature and difficult to break through. However, as far as the current market is concerned, it is believed that in the near future, high hardness liquid silicone rubber raw materials will gradually break through this limit.
