Why is hot melt adhesive used for metal stickers not sticky enough?

nickel metal sticker 56 - Why is hot melt adhesive used for metal stickers not sticky enough?

Metal stickers are widely used in electronic products, home appliances, machinery and civilian products. The production of metal stickers is mainly based on copper, iron, aluminum, zinc alloy, titanium, stainless steel and other raw materials. Recently, customers have asked why metal stickers will fall after using hot melt adhesives? As long as you know the sticker production process, you can see if it is a hot melt adhesive problem?

  1.  Improper use of hot press

The hot-pressed label is pressed and heated on a hot-press machine through a thermally conductive copper mold. If the imbalance between the copper mold and the product results in high sides and low sides, some stickers are not evenly heated. Therefore, a verticality needs to be adjusted between the copper mold and the sticker.

  1.  The hot pressing temperature is insufficient and the hot pressing time is insufficient

The standard melting temperature of hot melt adhesive is 70-90 degrees, and the hot pressing time is selected according to the characteristics of the product. If the temperature is too high, the hot melt adhesive will evaporate and the amount of adhesive will decrease. As a result, the label cannot stick to the product surface. If the temperature is too low, the hot melt adhesive will not melt, or it will not melt completely. This problem usually manifests itself as the product falls later.

  1.  Use inferior hot melt adhesive

In order to save costs, many sticker manufacturers use inferior hot-melt glue. The reason why most metal stickers drop off is related to inferior glue. Especially with nickel plating and stainless steel stickers. Therefore, when ordering hot-pressed stickers, major businesses should choose a strong sticker manufacturer, such as Shenzhen JTT Metal Precision Co.,Ltd。
