A less common water-resistant zipper is similar in construction to a standard toothed zipper, but includes a molded plastic ridge seal similar to the mating surfaces on a ziploc bag.
32.
The problem, you see, is that while there are four separate mating surfaces involved _ top, end, bottom and shoulder _ not one of them involves mating two glue surfaces.
33.
During the cyclic load several factor also contribute to microcrack generation such as frictional sliding of the mating surface, progressive wear, residual stresses at grain boundaries, stress due to shear.
34.
Both of these processes form the bonds with a hard faced bonding tool that makes direct contact to deform the gold wires against the gold mating surfaces ( Figure 2 ).
35.
The gold alloys'slight malleability facilitates the creation of a superior molar mating surface with other teeth and produces results that are generally more satisfactory than those produced by the creation of porcelain crowns.
36.
From the engine / trans mating surface to the cross member mount bolt is, and engine / trans surface to output shaft housing mating surface is overall, with the tail shaft housing typically measuring.

38.
The best fits are generally attained by selecting slightly oversized parts ( or altering stock parts to form an interference fit ) and then lapping the mating surfaces to attain the desired fit ( clearance ).
39.
Factors such as hardness, phosphorus content, the presence of corrosive liqiuids or gases, the temperature, the nature of the mating surface, the degree of lubrication and the characteristics of the substrate are critical to optimum performance.
40.
Frequently, these seals are the source of noise due to movement of the door against the car body and the resulting friction between the EPDM rubber and the mating surface ( painted sheet metal or glass ).
