Because of the good demolding property, silicone mold is widely used for so many foods. Now people also use silicone molds for candy. Lately the most popular star lollipop is also made of silicone mold. Star Lollipop is a creative candy from the United States. Some people on the Internet also called it the solar system lollipop. It is a handmade lollipop. The sugar ball is made of high quality natural syrup, and in the middle of the sugar ball, there is a beautiful star pattern, which is used food-grade colors print on the glutinous rice paper. It is really very beautiful and delicious candy.

Nowadays, the application of silicone is more and more extensive. From the beginning, it was used for silicone keypad, waterproof ring, sealing ring and other mechanical and electronic products. But today, it is used in all aspects of our daily life, such as our daily utensils, ice models, etc. As well as the daily used notebook cover, mobile phone protective cover, tablet PC protective cover and other fields. It can be said that a new type of silicone product is successful or not, mainly determined by the mold. At present, the traditional remote control, telephone keypad mold development has been more mature. Some new product development, design and processing is constantly improving.

As a kind of environmentally-friendly raw material, silicone is loved by people because of its various advantages. Its suppleness and non-toxic make it can be widely used in industrial sealing and medical equipment. Especially, its operating temperature is -60℃ to 250℃, which the plastic can't compare with. The use of silicone wrap metal parts or plastic parts to form some new features can make the silicone product both soft and hard. For example, silicone-wrap-steel kitchen spatula quickly becomes a favorite because the environmental performance.

Fondant mold food-grade silicone is an addition-type silicone, also known as two-component room temperature vulcanization silicone. Silicone A, B components are fluid colloid, in which B component contains platinum catalyst or other additives. A and B components in accordance with the ratio of 1:1 mixture can be heated or room temperature vulcanization.

Thermosetting liquid silicone rubber (LSR) injection mold structure, in general, is similar with the thermoplastic structure mold, but there are many significant differences. For example, LSR compounds generally have lower viscosities and therefore have very short filling times, even at very low injection pressures. In order to avoid air entrapment, it is important to provide good venting device in the mold.

At present, the molding silicone rubber is two-component liquid silicone rubber, divided into condensation and addition. Condensation mold silicone rubber main components include: Silicone (raw rubber) of end groups and part of side groups are the pendant hydroxyl groups, fillers, crosslinking agents and vulcanization accelerator. Addition mold silicone rubber main components include: Silicone (raw rubber) of end groups and partial side groups are vinyl groups, hydrogen silicone oil (Crosslinking agent), platinum catalyst (catalyst), and white carbon black (filler).

Silicone rubber is very versatile as special mold material. Silicone rubber has excellent performance and wide range of uses than any other mold materials:
  • Silicone rubber has good simulation, strength and low shrinkage.
  • Mold making method is simple and easy, can be cured at room temperature. Silicone rubber mold has good flexibility. Convex and concave part of the casting molding can also be directly removed.
  • Silicone rubber mold can withstand repeated use. It can maintain the prototype parts and can be used for small batch production of products. Mold modification is also very convenient.
  • Mold can also add metal inserts and other parts. The finished products can also be electroplating and painting.
  • Without any release agent.
  • High temperature and all kinds of acid and alkali substances. Therefore, in all need to use the mold industry like the decorative building materials, arts and crafts, precision casting, glass and steel industry, gypsum cement products and plumbing seal, polyurethane foam adornment and so on can use silicone rubber molds.

Stir the silicone and curing agent. Mold silicone appearance is flow liquid, component A is silicone, component B is curing agent. For example: Take 100 grams of silicone, add 2 grams of curing agent, silicone and curing agent must be evenly stirred, if not, the mold will have bad curing. Silicone mold non-uniform drying and curing will shorten the service life or even result in mold scrapped.
Silica gel
Hardener
In the mold production process to add too much silicone oil, silicone oil damaged the molecular weight of silicone, so the mold will appear low durability. If the small pieces of product patterns to more complex products, with a large hardness of silicone to open mode, there will be a small number of turn the mold, because the silicone will be very brittle, easy to break.Silicone mold demolding On the contrary, if you do to build products with a small hardness of silicone mold, the results will also be unsatisfactory. Because the silica gel is too soft, its tensile strength and tear strength will be reduced, the mold will be out of deformation, so the number of turn the mold will be reduced. Mold silicone itself is very good quality, good or bad silicone is not only suitable for and not suitable. We have to use the size of the product for the hardness of silica gel to produce mold will not happen this situation.
Silicone round ice cube mold is made of food-grade silicone raw materials. It's environmentally friendly, healthy, safe and durable. Its material is soft, can make you more conveniently to remove the ice from the mold. The silicone mold has non-toxic, will not crack, and will be long-life. It really does not stimulate the skin. The usage effect of silicone mold is far higher than ordinary rubber and plastic. This product is in line with China, EU, US and other countries standards of food hygiene. Now it's sweeping the world.
