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, pressure 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. y popular among sports players. Let us see several kinds sports bracelet. Glow in dark silicone wristband is popular for night event. But it is also good for night walk or run. A glow in dark silicone wristband can glow green or blue afrrubber band bracelets picturesubber band bracelets picturester absorbing strong light energy. The glow will fade gradually in about 3h and will recover absorbing light again. UV silicone bracelet is a good choice for out door activities or sports like Climbing, rock climbing, cliff descent, kayaking, diving, sailing and so on. A UV silicone bracelet can transfer it’s color darker under sunshine when absorbing UV light. It transfer to purple or blue normally which indicating the strength of the UV index. Wearing it on the wrist is a good way to avoid long time staying under strong sunshine. A mosquito repellent silicone bracelet is very useful to protect ourselves from the mosquito outdoor. It is made from high quality silicone together with lemongrass, lavender, clove and other natural plant oils. And the natural plant oils is the reason why it is mosquito resisting. Usually sport player has bigger size of wrist than most of us. So we have to choose the right size. There are 6”(150mm) for toddler, 7”(180mm) for youth, 8”(202mm) for adult and extra large of 210mm, 250mm in circumference and 1/4”(6mm), 1/2”(12mm), 3/4”(19mm), 1”(25mm) in width. We make it all together 2mm thickness.
