FAQ

  • Q: what is the minimum and maximum thickness of book case can be used for hot foil stamping and deep embossing and de-embossing ?

    A: It is up to the mold thickness，for car-bored paper from 80g to 2000g/m*2,and corrugated less than 5mm thickness，book case, keppa board and printing paper.

  • Q: Can we stop the machine in closed position for 2 seconds to increase contact time for better foil transfer?

    A: Yes , this requirement can achieved by setting on the PLC,the stamping and foiling time from 0.01second to 10 mins..

  • Q: How do u know the front lay positing while pasting dies on heater plate?

    A: The machines have a standard position of 7mm from the edge of the paper side to the edge of the heater plate.

  • Q: What is the thickness and material of plate where you paste the foiling stamping dies?

    A: In China we use a PET material film that we can scale into the aluminium plate which attached at the bottom of the pressing system of the stamping machine. The big aluminium plate is 6mm thickness and size 780*560mm and it is hold with screw and locked , and the hot stamping mold or dies are glowed on the surface of the plate.The special order of the dies it can vary from 1.5mm to 7mm thickness according to customer need and the dies company will， it has copper magnesium,aluminium, and copper ete. in many materials.

  • Q: What kind of the products the hot stamping foiling machine can run?

    A: It can run different types of paper like cardboard of 250gsm to 2000gsm,or corrugated paper less than 7mm thickness. The finished products for example of book cover, liquid box, cigarette box, luxuries packaging.

  • Q：What is the body part material of the machine?

    A: Changrong hot stamping machine is entirely constructed from a piece of iron called nodular graphite cast iron,in this way the central structure will be more High resistance to fatigue and impact, capable of withstanding high strength and toughness, able to endure significant external forces and shocks. Suitable for components subjected to complex stresses and heavy loads.

  • Q: How is the machine giving paper ?

    A: In the printing industry, there are many ways of giving paper. Paper feeding method for the sun wheel is passing the paper by lead edge feeder combined with servo motor and the other one is bottom suction paper feed mechanism which will cost less scratching of the paper Speed？

  • Q：How the machines work？

    A: The structure of the metal parts is very heavy which will apply more pressure; marching with heating system,it will pass the foiling paper into the paper cardboard or corrugated paper.

  • Q: Is the machine hydraulic and better in this way ?

    A: The traditional hot stamping high pressure foiling machines are normally ,mechanical ways. The hydraulic one cannot adjust the stamping position well and the time using of the machine is less because of the machine is less because of the sealing ring will easily needed to renew. With the limitation of the hydraulic way, the machine is not suitable for back and for multiples stamping.

  • Q: What is the efficiency of the machine?

    A: Our machines can run 2500 times every hour no need for taking a break at all. One worker can manage two sets of the machine at the same time, and the machines can run all day long for higher speed.

  • Q: Are the machines easy to maintain for a long period of time?

    A: Yes, this hot stamping machine which works in mechanical way is less complex with the hydraulic ones.
