Injection molding machines is one of the most effective ways to mold rubber. With injection molding, the rubber is heated until it becomes a paste and then the rubber is forced into a mold where it to harden. Rubber pieces produced this way are strong and unlikely to lose their shape. Compression molding is a very common style of rubber molding where a mold is placed in or near a cavity. Plates are then utilized to force the elastomer to fill the cavity. The elastomer is then vulcanized and removed.
When you have a mix between compression and injection molding this is known as transfer molding. In this process the user will place a large piece of into a pit. A machine then presses the rubber into the mold, where the rubber conforms to the shape of the mold.
Almost every industry utilize some style of molded rubber products. Manufacturing operations involving machinery often must contend with issues of vibration caused by moving parts. In order to protect workers, other machinery and the vibrating equipment itself, machinery that creates vibration is often secured using rubber washers or bushings that absorb vibration and prevent excessive movement, these parts are produced by rubber molders.
Another popular rubber molded product is a rubber grommet. Rubber grommets are used in industrial, commercial and consumer contexts. A rubber grommet is a rubber shape that fits around a hole in a surface, the grommet can protect wires or other hardware that passes through the hole.
Most rubber molders are equipped to do custom rubber molding jobs. Custom rubber molders can create a design and manufacture it on the spot. Customized designs are better for certain companies that require unique designs for their needs and new products. When using custom rubber molders, the run time of the process is reduced. Customers will save both time and money for large volume rubber runs by finding the right custom rubber molder.
The latest rubber molder machines have a variety of automation capabilities that reduce the cost of custom molding even lower. Using a material like a liquid silicone rubber creates precise, tight tolerance parts. It is possible to create products with a variety of finishes and textures when using rubber molding. There is almost no end to the type of products you can have produced affordably using custom rubber molders.
