1. Why silicone mold will be fewer turning models?
If the products do little more complex patterns come with a large hardness silicone mold, there will be a fewer turning molded phenomenon, because silicone excellent time will be very brittle and easily broken. Conversely, if you do build a product to do with a small hardness silicone mold, the result will also be unsatisfactory. Because silicone is too soft, it will reduce the tensile and tear strength, made out of the mold will be deformed, turning model number will be reduced. Mold itself good quality, silicone no good or bad, only suitable or unsuitable. We want to use for the product to make the hardness of the size of the silicone mold will not appear in this situation.
2. Why mold silicone mold phenomenon appears to burn?
Because unsaturated resin and resin products plus a peroxide curing agent after the case of the resin reaction will generate a lot of heat, usually resin curing time is 3 minutes, then three minutes after going to release soon, will not be able to prevent the silicone mold produce burning mode phenomenon.
3. Production methods of filling the mold and the mold silicone mold fragments?
Slice mold or sheet molding method of operation: the smoked silicone vacuum infusion method to brushing or construction. If you are a do-chip mode or slice mold has adopted brushing way, first before brushing on a layer of release agent or release agent, you want to copy the product or model brushing and brushing the silicone in the product above (note: Be sure to brush evenly) after waiting 30 minutes, the surface of the paste layer of gauze or glass fiber cloth to increase strength, then coated with a second layer of silica gel, silica gel drying, do outside the mold, the mold can be used outside plaster or resin and other materials. Operation mold filling or cast pouring: filling the mold or cast pouring, is used to smooth or relatively simple product, that the product or model you want to copy, use a plastic sheet or glass-enclosed, the smoked vacuum silicone directly into the products above, to be molded silicone dry, remove the product, mold on the shape (Note: cast pouring generally used hardness is relatively soft silicone mold to do, so stripping easier, will not damage the silicone mold inside the product) the above is the entire process of silicone mold use and operation.
4. Why silicone mold will appear in the table dry phenomenon quit?
Silicone mold belongs to condensation silicone, it is absorbed by the moisture in the air and cured silicone in the process of making, the water evaporated, while there is no transferred amount of water, this phenomenon occurs. Solution: This phenomenon does not belong to product quality issues, because there is no control of moisture, silica gel to enhance shelf life, the shelf life of these phenomena appear long, as long as the use of silicone, when the appropriate amount of 0.05% water, stir it these conditions can solve.
5. Why mold silicone rubber tension difference phenomenon?
In the process of making the mold, in order to reduce the viscosity of silica gel, making it easy to operate and large amounts of added silicone oil in the silica gel, will make silicone is very soft, not resistant, pull, tear strength is reduced, the phenomenon of tension variation, resulting in the mold is not durable, service life is short, the phenomenon such as fewer rolling over.
6. Why does mold appear to take oil condition?
Silicone rubber mold doesn’t bleed, because in the process to operate add to mixed mode oil silicone (Silicone oil and white mineral oil complex ligand ), because white mineral oil is Petrochemical Products, not oil silicone.
7. Why does the mold produce Acid and alkali resistance, aging resistance phenomenon?
In the process of making silicone rubber, we suggest customers don’t each oil silicone, if need, oil silicone add to doesn’t most more than 5%-10%. because add to too much oil silicone The bad molecular weight of silica gel make mold will produce no resistance to acid and alkali, not resistant to the aging phenomenon.
8. Why do out-of-the-mold silicone mold surface traces occur, stripes, not a smooth phenomenon?
This phenomenon is a product or a model to be replicated no grinding or polishing sake. In fact, the model of the product itself is not enough to smooth or perfect, if the product or model is to be replicated, not polished or polished, even the best silicone molds will do pretty, not smooth enough. Another case is when playing a release agent, there is no uniform brushing can also cause mold is not smooth.
