RUBBER BONDED TO METAL & PLASTIC
Manville offers the ability to not just glue or adhere rubber to substrates, but to create a true vulcanized bond so tough and durable that the bond strength actually exceeds the strength of the rubber material. This type of bond is created with the metal or plastic parts being coated with rubber in situ in the mold during the rubber vulcanization. With this technique design engineers are able to combine rigidity, flexibility and resilience within a single finished component.
Consider a rubber to metal or rubber to plastic bonded part for:
- Achieving unique finished part properties, combining rigid and flexible elements
- Simplifying the final assembly by using one component where previously multiple parts were required
- Eliminating wear between components by replacing surfaces that previously simply butted together with surfaces that are intimately bonded together and can no longer move by slip with respect to one another
- Rigid elements (i.e. the metal or plastic inserts) must be loaded to the mold for processing and therefore must withstand high temperature and high pressure. Typical molding cycles range from minutes at 375F for small, thin parts to in excess of an hour at 300F for large, thick parts
- Tight tolerances are required of the metal or plastic inserts so that fit to the mold is consistent from piece to piece and does not impact mold closure or risk any damage to the mold
- The part design must allow for positive location and registration of metal or plastic insert to the mold. Further, upon mold closure the insert must be captured by the mold features......inserts cannot "float" within the mold
