SHENGHUI has extensive experience in the large-scale production of food-grade liquid silicone molded parts. We have long-term partnerships with many major manufacturers as well as Fortune 100 and Fortune 500 companies. With our professional technology, we can provide strong support for every link of the production process, from the initial product design stage, to part production, and finally to the value-added processing after molding.

What is Liquid Silicone Rubber (LSR)?

Liquid Silicone Rubber (LSR) is not only odorless and tasteless but also has natural anti-mold and anti-bacterial properties. It can effectively resist various pollutants, building a solid defense line for product safety. At the same time, its hydrophobicity gives it good moisture resistance, and it is very convenient to clean, providing a reliable protective barrier for food-related products.

SHENGHUI selects a large number of high-quality food-grade elastomer materials. To ensure the stable supply and quality of raw materials, we have established long-term cooperative relationships with top global material suppliers. Our experienced expert team will conduct in-depth evaluations of the project’s schedule and cost objectives, fully understand the product specifications and performance requirements, and provide customized solutions for customers.

Injection Molding Parts for Food and Beverage Products

In addition to a wide variety of liquid silicone rubber materials, SHENGHUI also offers multiple options for the large-scale production of food and beverage products:

1. Injection Molding: SHENGHUI’s liquid silicone rubber injection molding units operate fully automated and have been finely tuned. They can produce parts with high precision, excellent consistency, and high speed. The injection molding process is versatile, suitable for both product prototyping and large-scale production. The liquid silicone rubber molded parts produced have no flash and minimal gate marks. Choosing SHENGHUI’s injection molding service can help optimize product quality, accelerate product launch, and provide value-added solutions to help customers effectively control costs.
2. Two-Shot and Multi-Shot Injection Molding: For components that require different characteristics (such as rigid and flexible physical properties), the LSR two-shot or multi-shot injection molding process offers more design possibilities. We use special self-adhesive food-grade liquid silicone rubber materials that can bond firmly with thermoplastic materials without the need for primers. In the same injection molding process, the liquid silicone rubber and plastic materials are molded and bonded together to form an integrated multi-material component with excellent bonding. This advanced injection molding process not only enhances design flexibility but also reduces the number of components and eliminates the need for secondary assembly operations, thus increasing product value.

SHENGHUI’s injection molding and multi-shot injection molding solutions can not only improve product quality and save production time but also optimize the post-molding processing. For products that require value-added processing such as assembly, printing, and slitting after molding, SHENGHUI integrates these processes. We use robots to complete these operations online immediately after molding, ensuring processing accuracy, adding value to the products, and simplifying the entire production process.
