LSR injection molding machine: innovation and application of liquid silicone molding technology

Liquid silicone injection molding technology is an important process in modern manufacturing, widely used in medical devices, electronic products, automotive parts and consumer products. As the core equipment of this technology, LSR injection molding machine has become an important tool for liquid silicone molding with its precise control system, efficient production capacity and excellent molding quality.
LSR injection molding machine is a device specially used for liquid silicone injection molding. Unlike traditional thermoplastic injection molding machines, LSR injection molding machines use liquid silicone raw materials instead of solid granular plastics. This raw material usually consists of two components (component A and component B), component A is liquid silicone, and component B is a catalyst. The two components are mixed in a precise ratio inside the injection molding machine, and then injected into the mold through the injection system for high-temperature curing.
The two components of liquid silicone are first mixed in a high-precision ratio in the injection molding machine to ensure uniform mixing. Then, the mixed silicone material is heated to a temperature suitable for injection.
The mixed liquid silicone is injected into the mold through the injection system. Due to its low viscosity, liquid silicone can quickly fill the details of the mold to ensure the accuracy and surface quality of the product.

After injection, liquid silicone quickly solidifies at high temperatures, usually between 100°C and 200°C. The cured silicone product will maintain its excellent properties such as elasticity, high temperature resistance, and corrosion resistance, and finally complete the molding.
After the curing process is completed, the mold will automatically open, and the cured silicone product will be taken out for subsequent quality inspection and packaging.
LSR injection molding machines are widely used in many industries due to their unique advantages. Here are some of the main application areas:
LSR has excellent biocompatibility and high temperature resistance and is widely used in the medical field. Common applications include medical device parts such as syringes, catheters, sealing rings, and baby pacifiers. Because liquid silicone is non-toxic, odorless, and has good antibacterial properties, it has become an important material for medical products.
Liquid silicone has excellent electrical insulation properties and high temperature resistance, so it is widely used in electronic products. Common products include sealing rings, connector protective covers, battery sealing covers, etc. for smartphones and tablets.
In the automotive industry, LSR is widely used in automotive seals, gaskets, buttons, dashboard components, etc. These components require materials with strong high temperature resistance, chemical corrosion resistance and long service life, and liquid silicone meets these requirements.
LSR injection molding machines are also used in the production of some daily consumer goods, such as kitchen supplies, toys, sports equipment, etc. The plasticity and safety of liquid silicone make it an ideal material for consumer goods manufacturing.
Liquid silicone has high transparency, so it is also used in the manufacture of optical products, especially in the manufacture of seals and gaskets for glasses and optical lenses.
LSR injection molding machines have many advantages that traditional injection molding technology cannot match during the production process:
LSR injection molding machines can ensure that the size and quality of each batch of products are stable and consistent through precise injection systems and temperature control systems. Liquid silicone can perfectly fill the details of the mold, thereby producing high-precision complex-shaped products.
The liquid silicone material used by LSR injection molding machines has low viscosity and can flow and fill the mold quickly. This not only improves production efficiency, but also reduces material waste and reduces production costs.
After liquid silicone molding, it has excellent properties such as high elasticity, heat resistance, UV resistance and chemical resistance. Therefore, LSR injection molded products can still maintain long-term stability under extreme working environments.
Liquid silicone is an environmentally friendly material that meets food grade and medical grade certification standards, is non-toxic and harmless, and is suitable for strict production requirements such as medical devices and food contact products.
Through different mixing ratios and processing techniques, LSR injection molding machines can produce silicone products with different hardness, transparency and color to meet the needs of different customers.
Although LSR injection molding machines have many advantages, they still face some challenges in the application process:
Due to the high precision requirements and complex control systems of LSR injection molding machines, their initial investment and maintenance costs are high, which may limit the application of some small enterprises.
Although LSR injection molding machines have high production efficiency, there are still certain bottlenecks in the production speed of some high-precision and complex products compared with traditional injection molding technology.
Although the material properties of liquid silicone are superior, the supply of high-quality liquid silicone materials on the market is still subject to certain restrictions, especially in some special application fields.
With the continuous advancement of technology and the expansion of market demand, the performance of LSR injection molding machines will be further improved and the production cost will gradually decrease. In particular, the increasing demand for precision and environmentally friendly products in the medical, automotive, electronics and other industries will promote the popularization and development of LSR injection molding technology.
