licone hand bands . The criteria for judging their quality are also different .Such as the printed rubber wrist bands ,our criterion for judging the quality of printed rubber wrist bands is whether the logo is clear and the color is correct . There are other ways to judge the quality of silicone hand bands . The first criterion is whether the plastic braclets is made of pure silica gel .The high quality rubber wrist bands is made of environmental friendly pure silica gel ,it has wear resistance,no deformation, no toxicity, no smell and no side effects on the human body .If we want to know if silicone hand bands are made of pure silica gel ,we can judge the quality of it by burning rubber wrist bands . If we don"t smell the pungent odor during the combustion process, and the product after combustion is grey powder ,the quality of the rubber wrist bands is good .The second criterion is whether tsilicone allergy bracelethe color of the rubber wrist bands correct .If the color of the wristband is same as the pantone color card ,the quality of the wristband is good .The last criterion is whether the edge of the rubber wsilicone allergy braceletrist bands smooth .A high quality rubber wrist bands ,the edge of it is very smooth . twenty-one-pilots-rubber-bracelettriple-single-rubber-band-bracelet youth, 8”(202mm) for adult in circumference and 1/4”(6mm), 1/2”(12mm), 3/4”(19mm), 1”(25mm) in width. We make it all together 2mm thickness. Regarding with the circumference, it is the most important factor to choose size in our order. It is the average sizes for toddler, youth and adult. The direct way to choose size is to measure the size of your wrist before selecting. If all the above sizes do not fit you, it is available for custom size. Our mould machine is updated to make variety of sizes. Printed, debossed or embossed with color silicone bracelets is of the most popular bracelets.Printed bracelets is the one that printed with color on the surface of the bracelets via the Screen Print. It is the plain and simple style to express yourself. Debossed or embossed bracelets is the kind that engraved lettering or raised lettering to let you message stand out. Also it can be color filled or printed to become a dazzling bracelets. A custom silicone wristband with different colors, logos or lettering is good for promotion of personal or the organization. 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.
