The connection of profiles into o-rings currently takes place in two forms:
- by gluing joints
- by vulcanizing joints
Bonding joints
- in this production process, the required length of seal is cut according to your requirements (the joint can be either perpendicular or oblique to ensure stronger adhesive joints)
- then the profile is cleaned and, if the material requires it (eg silicone seals) a primer is applied (a substance ensuring significantly better tack of joints)
- the next step is the gluing with a second glue.
- the last production step is to check the joint by a tensile test
Vulcanized joints
- this process is much more difficult
- as with gluing the joints, the first step is to cut to the required length
- then comes the cleaning
- preparation of raw mixture for vulcanized joint
- vulcanization itself
- modification of vulcanized joint
- joint inspection and testing
The whole process takes place on special single-purpose vulcanizing presses. The great advantage of this process is the improvement of the dynamic properties of the joint and the possibility of producing o-rings from 350 mm to several meters
