What is industrial hot stamping? What is the difference between hot stamping and heat transfer? While both fall under the “hot stamping” field, there are differences to the process and type of material that can be used.
When you think of hot stamping, you often think of screen printing t-shirts. Industrial Hot Stamping Equipment is different. The process still utilizes heat, pressure and precision timing to transfer color from a foil to an object, but the process is heavy duty with an industrial grade hydraulic or pneumatic press.
A silicone or metal die, machined to match the desired image, is used to bond the adhesive coat of the foil to the surface of the object that is to be decorated. This machinery can be used on flat or contoured parts and is ideal for single color transfers.
Materials used in industrial hot stamping are: Plastics, Wood, Paper or Vinyl. Metal, brick, glass, painted surfaces or textiles are typically not used with this process (unless integrated with a special coating) and mostly utilize heat transfer equipment.
Industrial Heat Transfer Equipment is similar to Hot Stamping Equipment and is applied in almost the same manner i.e. it utilizes heat, pressure and precision timing to decorate an object. However, in this type of decorating, the film carrier is printed with a multicolored image that is transferred. Proper indexing of the transfer is necessary to ensure correct placement of the image on the object.
This type of machinery can be used on flat or contoured parts and is ideal for single step multicolor transfers. It can also be utilized on Metal, Plastics, Rubber, Glass and Textiles.
The textiles in industrial heat transfer do not typically utilize screen printing. These items are usually logoed apparel for small logoes (up to 2″ x 3″), tagless tags, shoe liners or sock liners.
