In today’s competitive manufacturing environment, businesses across various industries—especially food, healthcare, and consumer products—are seeking precision-engineered, high-quality materials. Liquid Silicone Rubber (LSR) is a top choice for these industries due to its versatile properties and ability to meet stringent regulatory standards. When it comes to food-grade silicone products, LSR offers distinct advantages, making it ideal for use in applications where safety, hygiene, and durability are paramount.
At Colosilicone, we specialize in the design and manufacture of liquid injection molding food grade silicone products. From raw materials to mass production, our team ensures each product is crafted to the highest standards. Our one-stop service approach, coupled with custom service capabilities, allows us to deliver tailor-made solutions that meet the specific needs of our clients.
What is Liquid Injection Molding for Food Grade Silicone Products?
Liquid injection molding (LIM) is a high-precision, efficient manufacturing process used to produce food-grade silicone products. This method involves injecting liquid silicone rubber into a mold cavity under controlled temperature and pressure. It is ideal for producing intricate, thin-walled components and offers significant advantages in terms of precision, cost-effectiveness, and scalability. The result is a product with excellent durability, flexibility, and resistance to temperature extremes, making it perfect for applications such as kitchen tools, baby products, and medical devices.
At Colosilicone, we specialize in liquid injection molding for food-grade silicone, ensuring that each product is manufactured according to strict industry standards such as FDA and LFGB certifications. This enables us to offer products that are safe for direct food contact, non-toxic, odorless, and environmentally friendly.
Machines Used for Liquid Injection Molding of Food Grade Silicone Products
The production of liquid injection molded food grade silicone products requires highly specialized equipment. At Colosilicone, we utilize a range of advanced machines, including vertical liquid injection molding machines (50T-160T) and horizontal liquid silicone injection molding machines. These machines are chosen based on the specific requirements of the product, ensuring that we can handle a wide variety of sizes and designs.
Choosing the right equipment is crucial for achieving optimal results. The tonnage of the machine—such as 50T, 85T, 100T, or 160T—depends on the size and complexity of the product. With our state-of-the-art machinery, we can accommodate different customer needs and produce high-precision food-grade silicone components efficiently and consistently.

Quality Control and Testing for Food Grade Silicone Products
At Colosilicone, quality is at the core of everything we do. Our dedicated quality control team ensures that every product meets or exceeds industry standards. We operate a 100,000-class cleanroom facility, and all raw materials are strictly controlled according to food-grade standards.
After production, each product undergoes rigorous testing, including VOC volatile content tests, LFGB tests, and FDA compliance testing. This thorough testing process ensures that our food-grade silicone products are safe for consumer use and free from harmful chemicals. Only after passing these tests are the products shipped to our customers.
Applications of Liquid Injection Molding Food Grade Silicone Products
Liquid injection molded food grade silicone products have a wide range of applications, including:
- Kitchen Tools: Silicone molds for kitchen products such as spatulas, baking mats, and cooking utensils are popular due to their non-stick properties and high heat resistance.
- Baby Products: Silicone nipples, pacifiers, and teething rings are commonly produced using liquid injection molding, offering safety and comfort for infants.
- Medical Devices: From gaskets to seals, medical-grade silicone components manufactured through LIM are used in various medical devices, providing flexibility, durability, and safety.
- Consumer Goods: Silicone seals and valves for household items such as water dispensers, food storage containers, and baby bottles are produced using LIM, ensuring long-lasting performance.
