Heat shrinking process of heat shrinkable sleeve

Release time:2019-12-02 Number of hits:973

【Abstract】: No matter the heat shrinkable sleeve is used as the lead wire marking or the special motor lead wire is used as the insulation and sealing protection material, only the heat shrinking process is scientific and reasonable, which can ensure the reliable, practical and stable heat shrinkage of the heat shrinkable sleeve. The following is the heat shrinking process of the heat shrinkable sleeve and its precautions.

No matter the heat shrinkable sleeve is used as lead wire marking or the special motor lead wire is used as insulation and sealing protection material, only the heat shrinkable process is scientific and reasonable, which can ensure the heat shrinkable sleeve is reliable, practical and stable. The following is the heat shrinking process of the heat shrinkable sleeve and its precautions.

Heat shrinking process of heat shrinkable sleeve: radial dimension design and heat shrink burst: the heat shrinkable sleeve will shrink by more than 50% in the radial direction after heating. Fixed on the quilt carrier, its radial dimension must be selected appropriately. If the radial size is too large, the heat shrinkable sleeve is not shrunk in place and cannot be fixed firmly; if the radial size is too small, the strong shrinkage force during heat shrinking and motor baking may easily lead to bursting.

Heat shrinking process of heat shrinkable sleeve: Baking tools and baking efficiency: Hair dryer, heating tank, lighter, oven and other tools can be used for heat shrinkage of heat shrinkable sleeve. In actual operation, the heat-shrinkable sleeve is baked with a blast electric heat gun equipped with a mobile power supply, which is the most efficient and most convenient to use.

Heat shrinkage process of heat shrinkable sleeve: heat shrinkage position and virtual shrinkage, insufficient shrinkage: the heat shrinkable sleeve used as lead wire identification has two requirements for the heat shrinkage position: one is to be close to the cold-pressed terminal, and the second is to be close to the cold-pressed terminal. The position of shrinking and fixing on the three (or six or nine) lead wires should be basically flush. If the shrinkage is caused by heat shrinking (the bottom part below), after the heat-curing process of dipping the paint, the fixed position of the heat-shrinkable sleeve before shrinking may be uneven, and the slight deviation of the shrinking position will affect the visual effect, and in severe cases, it will affect the Marking effect or even falling off. The heat-shrinkable sleeve of the insulating sealing protection material for special motors, the virtual shrinkage also affects the protection of the connecting end or the cold-pressed end of the lead wire and cable. In addition, it is best to inspect the material when it enters the factory to avoid the phenomenon of insufficient shrinkage of the heat shrinkable sleeve (it will not shrink when it reaches a certain temperature or heats up again).

Heat-shrinking process of heat-shrinkable sleeve: Impregnation paint adhesion and protection: Since many motor manufacturers use epoxy-type impregnating paint to impregnate and bake motors, in order to prevent the heat-shrinkable sleeve from sticking together during baking and affecting the use, it will be properly used before dipping. method to hold the heat-shrinkable cable in place. The inner press-fit motor uses a concave baffle to prevent the heat shrinkable sleeve from sticking.

Heat shrinking process of heat shrinkable sleeve: dirt and protection: processes such as dipping paint, junction box wiring, etc. may stain the heat shrinkable sleeve logo, so when using shrinkable heat shrinkable sleeve, corresponding protective measures should be taken and strengthened examine.
