counterfeit silicone products.So how do we judge the quality of silicone products when we buy silicone products? First, wear resistance Wear resistance is formed after the production of athletic silicone products. The surface of silicone products can resist loss. Good athletic silicone products generally have little surface friction because of external factors, do not affect the appearance of performance, text, color. However, the surface characters of inferior quality silicone products are easy to fall off. Second. Tear strength and tensile strength Athletic silicone products with high tear strength have outstanding anti destructive ability,Long life,not easily affected by external environment. Poor tearing strength of silicone products is generally manifested in the tearing process prone to cracks, thus rapidly expanding the cracking and causing damage. Third, hardness and tensile stress An important indicator of the rigidity (stiffness) of the rubber material. Hardness and elongation stress are the forces needed to produce certain deformation of silicone products.So when buying silicone products, the most important thing is to look at the wear resistance, elasticity and tear strength first. If it meets the requirements, it is a good quality silicone product. If it is not satisfied, give up, so as not to cause financial loss. Fourth. Elasticity Athletic silicone products have good elasticity because high elasticity mainly comes from the movement of molecular segments of silicone.So when buying silicone products, look at the elasticity of silicone products to judge the quality. Fifth. Fatigue resistance When the silicone product is subjected to alternating stress (or strain), the change in the structure and properties of the material is called fatigue. The fatigue damage is caused by fatigue failure as the fatigue process proceeds. camo-silicone-wristbands24-hour-silicone-wristbands styles. We make a mold and set it in the machine, the high temperature of about 200℃ will solidify rubber into the sharp of bracelet. let"s see how the mould come into being. Mold, industrial production to use injection, blow molding, extrusion, die-casting or forging and forming, smelting, stamping and other methods to get the various models and tools of the required products. In short, mold is used to make molding tools. This tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the shape of the articles by changing the physical state of the formed material. It has the title of "the mother of industry". Under the action of external force, the billet becomes a tool with specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, compaction of powder metallurgy parts, pressurebracelet bbracelet blanks for jewelry makinglanks for jewelry making casting, and plastic or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape, and the shape of the cutting edge can be used to separate the blank from the contour line (blanking). The shape of the inner cavity can be used to obtain the corresponding three-dimensional shape of the blank. The mold generally consists of two parts, the movable die and the fixed die (or punch and concave die), and the two parts can be divided into two parts. When separate parts are removed, the blank is injected into the mold cavity to form. The mold is a precision tool with complex shape, bearing the bulging force of the billet. It has high requirements for the structure strength, stiffness, surface hardness, surface roughness and machining precision. The development level of die production is one of the important symbols of the mechanical manufacturing level.
