Rubber Metal Bonding
One of our many specialties at Cramer’s Precision Manufacturing is using our precision cnc machining equipment for bonding rubber to metal. It’s a complicated and precise process that our experienced staff has mastered into an art form with the use of cnc precision machining equipment. The decades of experience at our high quality machine shop has perfected our process and our top of the line high precision machining equipment produces the very best precision machine parts. There are several steps to the process including cleaning the metal, applying the adhesive and molding them together.
The first step of the rubber bonding process with the use of precision cnc machining equipment is prepping the metal to have the adhesive placed over it. Whether its metal inserts set to be entirely encapsulated in rubber or precision machine parts set to only be partially covered in rubber, the surface has to be clean. There can be no oils, dust or residue on the metal surface. The presence of these particles will harm the bonding process by creating a barrier between the adhesive and the metal. The metal will be sent through a degreasing system for optimum cleaning.
Once the surface is free of particles and residues the adhesive can be applied. The heat activated adhesive is applied in a manner much like spray painting. The inserts or precision machine parts that are set to be covered in rubber are then set into a mold. Specialized magnets are placed strategically throughout the mold in order to hold it in place. The products set to be completely enclosed in rubber often have chalet pins in the mold in order to hold the insert in place. The rubber is then poured into the mold and set to dry. The adhesive is heat activated and the high temperature of the rubber will begin the bonding process between the rubber and metal. This process is made possible with our highly efficient precision cnc machining equipment.
Rubber to Metal Bonding Products
Rubber to metal bonded products are most frequently seen in automobiles, computer equipment, industrial parts, and in electrical equipment. In automobiles rubber bonded metal parts are used to decrease sound. Metal on metal brushing and buffering creates noise and erodes the precision machine parts. Encasing these metal pieces in rubber greatly reduces sound and protects the precision machine parts from erosion and break down. Often hoses, mounts, seals, and instrument panels will feature bonded rubber to metal parts. These are seen in everyday cars and trucks but especially in heavy industrial equipment. The jobs of industrial equipment require a lot of force and therefore can create just as much noise. Having rubber encased metal parts is vital to noise reduction.
Rubber bonded to metal isn’t just great at reducing noise, it is often used to protect from electrical current. In transformers, computer parts and cable connectors electricity is being routed from one place to another, from a source to a destination in need of power. Metal is a conductor of electricity and many parts of the transformers or cable boxes need to be encapsulated in rubber so as not to avoid conducting electricity to the wrong areas.
