The silicone folding cup is a kind of folding cup that is easy to carry, hygienic to use, and has a double wall. Screw threads connect the two adjacent sections of the outer wall, and the two adjacent sections of the inner wall are in a conical fit and can move up and down. The inner wall is unfolded up and down through the rotation of the outer wall thread to achieve cup-shaped folding and stretching kinetic energy.
Silicone folding cups are made of environmentally friendly, non-toxic, and safe food-grade silicone. The most used silicone kitchenware in our daily life is: silicone cups, silicone forks, silicone shovels, silicone tableware, silicone bowls, silicone insulation pads, silicone insulation gloves, silicone pacifiers, etc., food-grade silicone is an inorganic polymer colloid material condensed from silicic acid, the main component is mSio2nH2O. Except for alkali and hydrofluoric acid, which do not react with any acid and alkali in two special cases, the chemical stability is good. Commonly used in silicone baby pacifiers, feeding bottles, and other products with high safety requirements. Heat resistance can reach 230 degrees.
Many people have asked before whether silicone products will react to high temperatures and emit some chemical raw materials? The answer is: it can be put into boiling water of 100 degrees, there will be no scalding, chemical disintegration, high and low-temperature resistance between -40 and 230 degrees, and there will be no problems because room temperature vulcanized silicone rubber and meteorological silica have With a certain toughness and strength, high-temperature baking will not cause deformation, toughness failure and other phenomena. Unlike plastic, silica gel does not contain BPA (bisphenol A), which is a food-grade environmentally friendly product. Filling boiling water is a trivial matter. Because food-grade silica gel material has a variety of unique properties, in addition to high-temperature resistance, it can also fully adapt to low-temperature environments and climates. For stability, the main component of silica gel material is carbon dioxide. Silicon, silicone resin, and silica, except for the catalyst (vulcanizing agent) added by the silicone product manufacturer, will not conflict with any substances, and the catalyst odor can be removed by secondary fluidization high-temperature baking.
The difficulty of making silicone folding cups is to fold the interval points, and other shapes other than arcs are difficult to achieve the folding effect. The drawings mainly depend on the wall thickness of the folding position. Generally, the wall thickness of the folding part needs to be as small as The thickness that can be bent back and forth can achieve a gradual gradient size. Usually, the wall thickness of the folding position is between 0.5-1mm. The folding position can be determined according to the size of the silicone water cup. Finally, the folding effect is achieved by the strength of the folded part.
Making molds also requires certain skills. When opening the mold, the upper and lower mold clamping interfaces should be in the smallest position. The slope of the product should be judged according to the taper size of the mold, and the minimum should be achieved to achieve the folding effect. The more common The problem is that the inside of the silicone folding cup is easily affected by the wall thickness of the folding part, so its internal folding point must be made into a structure that slopes from top to bottom or from bottom to top so that there will be no extrusion expansion during folding.
In the process of silicone processing, the folding silicone water cup also has a certain impact on the hardness of the product and the quality of the variable material. If the material with lower hardness is used, the subsequent estimation of the folding strength is not enough, resulting in the automatic rebound, and the use of high hardness may cause folding. If the strength increases, it is not easy to fold. Secondly, the material of the product is affected. The high-tensile silicone rubber material is necessary raw material. Otherwise, the long-term pressing and pressing may cause the product to deform and the folding effect will deteriorate.
