Food grade liquid silicone rubber provides high strength and stress resistance to manufacture kitchen and household products, such as baking trays, bottle dispensers. It is also used for gasket and seal in industrial cooking appliances. There is no doubt that food-grade liquid silicone rubber encourage high quality and durability in bakeware and consumer goods to the widest world-wide market.
Miwo specializes in various volume of food-grade LSR for major manufacturers and international enterprises. With our 20 years experience and professional engineering team, we can assist with every aspect of LSR production, from mold development to final packaging.
What is Liquid Silicone Rubber(LSR)?
LSR is an elastomer with high temperature resistance, flexibility and non-stick nature. In addition, it is odorless, tasteless, bacteria and mold resistant, and hydrophobic. This make it an excellent choice for any products in contact with food.
Miwo normally apply Dow Corning and Topco silicone materials to produce wide food grade elastomers. Therefore, following careful reviews of your specific budget and product requirements, we can recommend the most suitable food-grade material for your unique demands.
LSR Molding Parts
Regardless of a wide range of different LSR grades and properties, Miwo also provides flexible design options to satisfy various LSR parts requirements.
- LSR injection molding: LSR injection molding is able to fabricate high precise parts in high speed and consistency. This process can scale easily from low-volume prototypes to high-volume production. Furthermore, all final parts are automotive controlled to be flash-free with minimal gate indications. We can optimize your production schedule to market with budget saving.
- LSR over-molding: LSR over-molding provides additional design flexibility for complex food-grade LSR production. We apply LSR over-mold onto plastic or metal substrate, this technology is ideal for adding silicone grips on kitchen utensils. Furthermore, it creates virtual unbreakable bonds with time and cost saving, eliminates any additional assembly stage.
Miwo has LSR molding capability to reduce steps from production to market. Furthermore, we also provide in-line assembly, design consulting, packaging and shipping assistance. For more information about our silicone capability, contact our marketing office today.
Benefit of Food Grade Liquid Silicone Rubber
Miwo can produce a wide range of LSR products with specific characteristics for food and beverage application. Comparing with other materials, food-grade LSR provides a number of advantages.
Durability
Food-grade LSR parts are flame retardant, corrosion resistant and rugged reliability. These products can withstand daily demands of kitchen or manufacturing facility. In addition, they are also exceptionally pure with low compression set, and absorb vibrations easily.
Process Flexibility
LSR parts can be manufactured by both conventional and 2-shot injection molding. This offers greater design flexibility and more potential manufacturing applications.
Heat and Cold Resistance
Extreme high and low temperature resistance is critical for food and beverage applications. Food grade LSR can maintain its properties in both extreme heat and cold conditions, never melt or become brittle. Comparing to other materials, it is more reliable equipment and more durable products, this is important advantages for any products.
Bacteria and Chemical Resistance
Food-grade LSR is chemical inert, it can resist bacteria and mold growth. This will assist risk management in supply chain with HACCP compliance.
FDA Compliance
Liquid silicone rubber application is the best way to comply with FDA regulations. In addition, Miwo is able to manufacture products compliant with FDA regulation CFR 177.2600. Such as baking molds, food trays and other kitchen products.
Common Applications of Food Grade LSR
Food-grade silicone is highly versatile, it is the most suitable choice for products in home kitchen and industrial manufacturing plants. FDA-approved food grade silicone is available for any application with supreme chemical and bacterial resistance requirements. Common products made of food-grade LSR including:
- Baking molds, ice cube trays, or other kitchen products with requirement to withstand freezing temperatures or hot ovens. LSR trays or molds won’t become brittle once exposed to cold. Furthermore, It has more durability than conventional plastic products.
- Rubber spatulas or grips for knives, whisks, spoons and other utensils. LSR is perfect for kitchen utensils, it is easily over-molded onto plastic or metal substrates. Therefore, manufacturers can produce complex products with less labor and cost.
- O-ring, gaskets, other seals parts exposed to food. These products range from home solutions to industrial equipment for food and beverage manufacturing, processing, transportation, and preparation. Therefore, LSR is an economical choice with easy sterilization, low creep and compression set, it even applied in heavy-duty applications.
As an advanced LSR manufacturing company, Miwo can find innovative solutions for various challenges. Contact our office directly for your next food grade LSR products.
Food Grade Injection Molding in Miwo
The first step of LSR designing is mold development, it is a complex process with precision machining equipment and careful considerations. There are some key questions we should discuss when developing a mold:
- How are the parts used? Does it work alone or in combination with other components?
- What is part’s working conditions? Are there any specific characteristics are required?
- What are the cosmetic performance requirements? Is the part intended for consumer or industrial application?
- What is the regulation requirement? Is the part FDA approval?
- What is the part size? What is the weight and load requirement?
The diversity of LSR parts make each mold development unique. Meanwhile, this is the most expensive step to bring a new item to market. Once cooperate with Miwo, our engineering team will go over your option in detail, in order to ensure this process is as quickly as possible.
