What are the common problems of rubber products

Why does the rubber mold have fewer times of turning?
Too much silicone oil is added in the process of making the mold, and the silicone oil sealing ring destroys the molecular weight of the silicone, so the mold will appear less than the number of die-turning is not durable, etc. If you make small products with complex patterns, use silicone with high hardness to open the mold, there will be liquid silicone with fewer die-turning times, because the silicone hard time will be very brittle, easy to break, on the contrary, If you build products and use silica gel with small hardness to make molds, the results will also be unsatisfactory.
Why silicone rubber mold will appear silicone products factory burning mold phenomenon.
Because unsaturated resin and resin products add peroxide curing agent, the resin reaction will produce a lot of heat, the general resin curing time is 3 minutes, so after 3 minutes to as soon as possible silicone button manufacturers release, in order to prevent the silicone mold will not produce burning mold phenomenon.
What are the skills of rubber products bonding:
1, seal silicone rubber products use white electric oil or toluene to clean the area of silicone rubber impurities that need to be affixed with double-sided tape (oil and water stains), add diluent in proportion to stir evenly for use.
2, note: silicone and rubber material is different, silicone miscellaneous parts with silicone treatment agent, rubber keys with rubber treatment agent, both rubber products can not be mixed wrong use, otherwise it will lead to double-sided adhesive degumming.
3, rubber products bonding skills: evenly apply the treatment agent on the silicone rubber parts need to back the adhesive area, after evenly spread the silicone rubber parts put rubber keys in a cool and ventilated place to be treated by natural air dry.
4, After the processor on the rubber parts is dried naturally, the double-sided tape is affixed to the area that needs to be affixed with double-sided tape on the silicone rubber parts, and the silicone parts have been tightly bonded to the double-sided tape.
