GBSA - Molded Rubber
All applications are not created equal. The different sizes, shapes, tolerances and uses will not only determine the design of the molded rubber parts, but also which materials will be best suited for the job. That’s why our engineers carefully analyze the properties and dynamics of the intended use of the part to ensure our molded rubber parts optimize your operations. Our expertise in a wide variety of elastomers and thermoplastic materials ensures that we deliver greater flexibility and fast turnaround times for a variety of applications including automotive, industrial, electronic, medical, mechanical and household items.
Molded Rubber Parts Seal Types
GBSA molded rubber parts are available in every conceivable configuration to fit your exact application. We have the ability to mold in odd shapes and exotic materials or colors.
We can supply either short or long runs and tooling costs are surprisingly low. Our deliveries are among the fastest in the industry for custom parts, going from concept to delivery in as little as 4 weeks. Our selection of materials is vast to allow our parts to give you the optimum performance in your particular application.
In addition to manufacturing custom molded rubber parts according to your requirements, we can also assist you with rubber to metal bonding. There are many uses for rubber to metal bonded parts – most commonly associated with isolating vibration or noise during manufacturing processes or in end user equipment. Some examples of parts that bond rubber and metal are oil seals, vibration dampeners, slingers, spacers and washers.
Rubber to metal bonding is a process that adheres rubber to metal parts in order to create a product that has an air-tight and water tight seal. The bonded metal gives the part strength and stiffness so it can withstand high pressure. The bonded rubber provides the metal with elasticity and damping properties. There are a wide variety of applications this process can be used for.
Injection molding is a manufacturing process where raw, uncured rubber is forced into a heated mold using a rotating screw. The material is formed and cured under the heat and pressure, then removed to cool as a custom shape.
Compression MoldingCompression molding is done by taking a pre-measured amount of raw rubber material and is placed into a heated open lower mold cavity. The top cavity is then forced closed, causing the raw material to flow through the shape of the mold. After curing, the shapes can be removed.
Transfer MoldingTransfer molding is where raw rubber material is measured and inserted into a pot. The pot is pre-heated and plunger forces the material into mold cavities through a funnel, or sprue. The mold is heated to cure the raw material. After curing, shapes can be removed.
Rubber ExtrusionRubber extrusion is a process where material is pushed or drawn through a die of the desired cross-section. The two main advantages of this process over the manufacturing processes are its ability to create complex cross-sections and long lengths. It also forms finished parts with an excellent surface finish.
