orfilled styles. We make a mould and set it in the machine, the high temperature of about 200℃ will solidify rubber into the sharp of wristband. let"s see how the mould come into being. Mould, 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, mould 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 mould 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 cankinds of rubber band bracelets be used to obtain the corresponding three-dimensional shape of the blank. The mould 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 mould 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. The most important factors of mold material are thermal strength and thermal stability. Materials uskinds of rubber band braceletsed for common materials: working temperature, forming materials, mold materials. make-your-own-silicone-bracelet-kitcoloured-wristbands-for-events r wristbands and so on . Each type of bracelet has its own characteristics . Such as the glow in the dark silicone wristbands can shine in the dark when it absorb enough light , the UV silicone wristband will change its own color when it absorb ultraviolet rays . Due to different production processes , There are also differences in the quality of rubber band bracelets . Is there any good way to distinguish the quality of rubber bracelet ? Of course , just like the traditional Chinese medicine treatment in China . We can also use four methods to judge the quality of silicone bracelets: look, smell, ask and touch . 1.Look ( Appearance of rubber band bracelets ) Check if there are any dirty things inside the silicone bracelet , such as some color deviation , printing errors , whether the diameter of the bracelet is regular , whether the edge of the bracelet has surplus colloid . Generally, the edges and surfaces of high quality silicone hand rings are very smooth . 2.Smell ( The odor of rubber band bracelets ) Silicone bracelets are generally odorless. During the test, we can use fire to burn silica gel bracelets, high quality silica gel bracelets the residue after combustion is powder . The inferior silica gel bracelet has a bad smell after burning . 3.Ask ( Raw materials for rubber band bracelets ) We can ask the supplier whether silicone bracelet are made of pure silica gel . 4.Touch ( Touch the surface of silicone wristband ) The surface of high quality rubber band bracelets is very smooth and it"s very elastic . The silicone bracelets usually be made by mould 4pcs output together. We have to separate them into one single piece by hand with a knife in the past. But now the edge cutting machine come into being. First put the 4 wristband to measure with the positioning system then after a few second the edge cut exactly by the machine. The wristbands come out evenly. A mosquito repellent rubber bracelet is very useful to protect ourself from the mosquito. Do you know what the mosquito repellent rubber bracelet consist of ? A mosquito repellent bracelet is made from high quality silicone together with lemongrass, lavender, clove and other natural plant oils. And the nutural plant oils is the reason why it is mosquito resisting. A mosuito repellent rubber bracelet is comfortable to wear on the wrist or leg as its good air permeability . It is designed as non contacting type of the controling module so safe for adult and kids.
