Rubber joint development up to now this stage is quite perfect and mature; especially on the production process of change makes the use of rubber joint surface is broader.
Early rubber joint production technology belongs to hard mold production, generally is the pieces of semi-finished products of rubber joint part of the sphere of together, and then high temperature circumstances make fusion, the production process is the main defect under pressure is small, short service life, because the interface is overmuch, inadequate high-temperature fusion, will lead to leakage of pipeline.
Now rubber joint production process based on module is given priority to, it is through the wrap has good semi-finished products for high temperature vulcanization rubber joint, the whole process can make a sphere parts can fully combine, colloid distribution more uniform, because it is the overall sulfide, so there is no interface problems too much, the new production technology promotion, makes the rubber joint bearing pressure increase is originally epidural two to three times, a considerable effect, long service life, simple and convenient to operate, greatly improves the production efficiency and product quality of rubber joint.
Consumers in the actual buying rubber joint how to distinguish which is a module which is a hard mode, the most simple and direct way is to see if the lining is smooth, because hard mold rubber joint is a patchwork of multiple parts, will strip joint between after molding, but not with the module of, because it is the overall vulcanization molding, smooth wall is give a person with aesthetic feeling.
