1. Why does the silicon rubber mold have less times of mold turning?

In the process of mold making, too much silicone oil is added, which destroys the molecular weight of silica gel, so the mold will appear less times of mold turning and not durable. If you do small products with more complex patterns, with a large hardness of silica gel to open the mold, there will be fewer times of mold turning phenomenon, because the silica gel will be very brittle, easy to break. On the contrary, if you build products and use small hardness of silica gel to do the mold, the result will also be unsatisfactory. Because silica gel is too soft, its tensile and tearing strength will be reduced, and the mold will be deformed, so the number of mold turns will be reduced. Mold silica gel itself is very good quality, silica gel is not good or bad, only suitable and not suitable. This situation will not occur if the mold is made of silica gel suitable for the hardness of the product.

2. Why does the silicon rubber mold burn?

Because unsaturated resin and resin products with 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 demoulding as soon as possible, to prevent the silicone mold will not produce burning phenomenon.

3. Why does the mold silicone rubber appear dry in the surface?

Mold silica gel is a condensation type silica gel, which is cured by absorbing moisture in the air. In the process of making silica gel, the water is dried, and there is no appropriate amount of water, and there will be a phenomenon of dry surface and dry surface. Solution: This phenomenon does not belong to the product quality problem, but because there is no control of water, improve the storage period of silica gel, shelf life will appear some phenomenon, as long as the use of silica gel, add 0.05% water, stirring evenly can solve some of the situation.

4. Why does the mold silicon rubber have poor tensile force?

Because the customer in the process of making mould, in order to reduce the viscosity of silica gel, the silica gel easy to operate and large amounts of added silicone oil in the silica gel, this will make silicone is very soft, not resistant, pull, tear strength is reduced, the phenomenon of tension variation, resulting in the mould is not durable, service life is short, the phenomenon such as fewer rolling over.

5. Why does the silicone rubber of the mold appear to bubble oil?

Mold silica gel itself is not bubbling oil, bubbling oil is because the compound silicone oil (silicone oil and white mineral oil complex ligand) is added in the process of operation, because white mineral oil is a petrochemical product, not silicon oil.

6. Why does the mold produce the phenomenon of acid and alkali resistance and aging resistance?

Liquid silica gel in the process of making silica gel mold, it is recommended that customers do not add any silicone oil, if necessary, the amount of silicone oil should not exceed 5% ~ 10%. Because the addition amount of silicone oil is too much, the molecular weight of silica gel will be destroyed, so the mold made will produce the phenomenon of acid and alkali resistance and aging resistance.
