Hello, young readers! Today, we are going to discuss something quite cool — liquid silicone rubber injection molding! The curing of liquid silicone rubber has its niche where hot liquid silicone is cast into a mold and you can create pretty much anything. Think about it as if we were making jello. But instead of eating them, we are able to design and create useful things that come out just the way they look. These range from phone cases or kitchen utensils such as spatulas to even necessary medical aids can be found in your nearest 3D printing outlet that help aid people stay healthy!
We begin with liquid silicone rubber poured into a machinebuilt just for the task. Well, this box does important work! It is two-part silicone being mixed together. Similar to the SAVs this comprises of two pieces one is referred to as base and second is referred to as catalyst. The machine then blends the nuts until they are smooth — kind of like a milkshake! Then, the thick paste is poured into a form shaped of rapide. This mold is a container that has the same shape as our target object. Then they heat it to REALLY, REALLY HOT… This heat causes the silicone rubber to solidify and conform to the mold. Then we simply wait for the silicone to cool off and not be warm anymore, then pull it out of the mold. Bingo! A shiny new object freshly minted!
You may be wondering then, why liquid silicone rubber is such a great material to use when it comes to producing parts through injection molding? Reason number one, well actually a few really awesome reasons. Now, the reasons are simple first of all Liquid silicone rubber is highly flexible. This means it can be bent and shaped, which is great for products such as phone cases or multicoloured bracelets that need to flex rather than snap. The second, however is it is one of the strongest materials out there, and can be wear resistant. Liquid silicone rubber products have a long service life and are not easy to replace. It is also very easy to clean! That makes it perfect for health-related tools or kitchen utensils that consumers want to quickly make safe.
At Rega (yixing) we are always eager to explore what can we do with LSR injection molding. An awesome trick we use is called overmolding. We slush cast liquid silicone rubber over a hard plastic part, such as toy or handle. It creates a product that is the strength of plastic and also the suppleness of silicone. Isn’t that neat? However, we are looking at using two colors of liquid silicone rubber in the same mold as well. What it produces are some very interesting looking products, which in turn make them more fun and appealing!
LSR injection molding is already producing a lot of great products, but we are convinced it can do much more! The automotive industry is a prime example, as it covers everything car/vehicle related. For example, liquid silicone rubber can tolerate extremely high heat, meaning that it might work well when used to develop parts for engines or anyplace else where the temperatures are off the charts. We also believe liquid silicone rubber injection molding can help us make more sustainable products. This strength, in turn, dramatically decreases the likelihood of silicone items ending up in landfills, which is a planet Earth win!
At Rega(jiangsu)In fact, all our has always wanted to find ways to make liquid silicone rubber injection molding quicker and more efficient. We work based on machines that will function automatically one of the ways. Electronics boards are placed onto the silicone in the mold, and then an automated machine mixes the material more consistently and pours it into the mold both faster and much more evenly that a person can. This helps us save time! We also reuse the molds [+ Used with permission. →] That way rather than having a new mold for every single object we make, the same mold can be used over and over. So this saves time, and allows us to save the resources and materials needed.
