The precision molding technology of liquid silicone rubber (LSR) is popularized, and daily silicone rubber is moving towards the era of "high precision+high efficiency"

With the continuous improvement of precision, performance, and appearance requirements for daily necessities silicone rubber products in fields such as consumer electronics, mother and baby, and smart home, liquid silicone rubber (LSR) precision molding technology has been widely popularized in the daily necessities industry, completely changing the dilemma of "low precision, low efficiency, and low yield" in traditional molding processes, and promoting the intelligent era of "high precision+high efficiency" in daily necessities silicone rubber manufacturing.

LSR technology has three core advantages: firstly, it has extremely high molding accuracy. By combining liquid injection molding with multi cavity precision molds, it can achieve a dimensional tolerance control of ± 0.03mm and a stable flatness within ± 0.05mm. It is perfectly suitable for daily necessities such as baby pacifiers, smart wristbands, household appliance seals, and precision buttons that require strict size and consistency; The second is a significant improvement in production efficiency. Automated production lines can achieve a closed-loop process of raw material mixing, injection, vulcanization, and demolding, with a molding cycle that is more than 40% shorter than traditional mold compression. The daily production capacity of a single equipment can be increased by three times, while reducing manual dependence and production losses; Thirdly, the product performance is superior. LSR products have no seams, smooth surfaces, no burrs, high and low temperature resistance (-60 ℃~250 ℃), aging resistance, and tear resistance, which are 20%~30% higher than traditional solid silicone rubber. They also have excellent biocompatibility and food safety, suitable for high-end needs of mother and baby, kitchen, and medical grade daily necessities.

At present, LSR technology has been widely used in all categories of silicone rubber daily necessities: in the maternal and child field, LSR made pacifiers, dental gums, and pacifiers have a soft touch, no odor, and are easy to clean. They can also achieve anti bloating and anti choking functions through precise structural design; In the kitchen field, LSR baking molds, scrapers, and sealing gaskets are high temperature resistant, non stick, easy to demold, and have a 50% longer service life than traditional silicone products; In the field of home furnishings, LSR smart buttons, waterproof rings, and anti slip pads are suitable for precision assembly and long-term stable operation of smart home products; In the field of decompression toys, the kneading and decompression balls made of LSR have excellent rebound performance, delicate hand feel, and can achieve complex shapes and multi-color integrated molding.

Industry data shows that the LSR penetration rate in the global daily necessities silicone rubber field has reached 45% by 2026, an increase of 20 percentage points from 2023. The domestic LSR daily necessities silicone rubber market has exceeded 8 billion yuan, with a compound annual growth rate of over 25%. With the deep integration of AI process control, digital twin, in mold sensing and other technologies with LSR molding, the yield rate has increased from the traditional 82% to over 96%, and production costs have been further reduced. In the future, LSR technology will expand towards functional directions such as self bonding, foaming, conductivity, and antibacterial, promoting the upgrading of daily silicone rubber from "basic sealing and flexible components" to "functional integration and intelligent interaction". At the same time, it will drive the coordinated development of precision molds, automation equipment, testing instruments and other supporting industries, and build a more complete intelligent manufacturing ecosystem for daily silicone rubber.
