Heat Shrink Tubing

Answer. A uses an oven; B uses an industrial hotblower;C uses boling waer, After a lot ofexperiments, we found thatthe heatshrinkable tube producecbyour company shrinks quickly and can save energy for customers. lt is recommended to choose the oven (there are two ypes of sealed hermostat andtunnel oven). The temperature can be set at 120*c~150'c, and the shrink time of large quantities of casings together is about 3~5 minutes; use industriahot air blower The barrel shrinkage time is aeneraly more than 3 seconds, and the hot blower can exceed 200'c athioh temperalures. The blower mouthmust be more than 2cm away from the sleeve to avoid scorching the sleeve: The shrinkage method used in bolling water is mainly because somecustomers'products cannot be soaked in wate* to avoid customers Products are oxidized, such as wires for LCD appliances.A/B two heat shrinkagemethods. For longer sleeves, atention must be paid to the exhaust of the sleeve.it is bestto shrink from one end to the otherto avoid bubbling after theair seal shrinks.

Answer: The heat-shrinkable product should be kept away from direct sunlight or the ambient temperature exceeds 60'c during storage andtransportation. When the ambient temperature exceeds 60'c, the heat-shrinkable product may partially shrink

Answer; The plug gauge (or mandrel is commonly used, Putthe plug gauge into thetube, There is no gap around itvisually. The mandrel should be easyto putin and outofthe tube.The outer diameler ofthe plug gauge is the inner diameler ofthe casing.The inner diameler value ofthe heatshrinkable ubis usually only kept one digit after the decimal point (in mm), and it is also usefu for proiection only equipment detection.An empirical formula formeasuring he inner diameter of a larger specification casing:inner diameter s folded diameter + 157 (where, folded diameter refers to the width ofthecasing when it is compressed in half

Answer: The professional and accurate method uses wall thickness gauges or proiectors to check, which can avoid human error. Heat shrinkage itselhas a certain deqree offlexibility, lt is generally used to usea vernier caliners to measure, but the measurement process needs to be mastered and theweight ofthe method itwill obviously affect the test results. in the heat shrinkable tube wall thickness industry,the average wall thickness is calculated(average wall thickness = (highest point value + lowest point value)/2, and the concentricity rate of its wallthickness is 270%, concentric Rate=lowestDointyalue/hiahest point valuex100%)

Answer: The formula for calculating the shrinkage rate in the axial direction (length direction) ofthe casing: shrinkage rate = length before fulhcontractedlength)before shrinkagex100%.
