Frequently Asked Questions

Q1)   What is hot foil stamping?
Ans.   Hot foil stamping is transfer printing process in which the coating on the stamping foil is transferred to the part. A stamping die with the desired design is mounted on the machine and with a combination of temperature, pressure and time the coating from the foil is transferred.
Q2)   What is heat transfer process?
Ans.   Heat transfer is a reverse printing process in which by the application of heat, pressure and time, preprinted image is transfer from heat transfer foil to the articles.
Q3)   On which material hot foil stamping / Heat transfer can be done?
Ans.   It is suitable for verity of substrates like plastics (PET, PP, HDPE…), Paper, Leather, textile, coated wood, coated glass and other similar materials.
Q4)   How to select machine for hot foil stamping application?
Ans.  

Step 1: select industry (from application column) to which your product belong
Step 2: find you product in the applications products photos scrolling top on the page
Step 3: the machine/s displaying on that particular page is suitable for you article

Q5)   How to achieve good hot foil stamping?
Ans.  

The 3 parameters that determine the stamping quality are TEMPERATURE OF THE STAMPING DIE, STAMPING TIME and STAMPING FORCE APPLIED PER UNIT AREA.

Foil of different grades are available for different substrates. The suitable foil can be selected from the foil manufacturer’s technical brochures.

Any change in any of the parameters will affect the quality of the transfer.

TEMPERATURE is require to activate the release coating and the adhesive coating on the carrier film and bond the metalized layer to the part.

PRESSURE is the force required per unit of the area to achieve the bonding.
STAMPING TIME is required to achieve the bonding of the image with the substrate.

Q6)   What is stamping foil?
Ans.  

The stamping foils are available in plain metalized colors.

The foil has 4 layers: the first layer is the carrier film made of Polyester or other plastic material, the second layer is a release coating, the third layer is the metalizing / pigment coating and the bottom layer is the adhesive coating.
