ultra-high frequency induction heating glasses flame


Induction heating is often used in the heat treatment of metal items. The most common applications are induction hardening of steel parts, induction soldering/brazing as a means of joining metal components and induction annealing to selectively soften an area of a steel part.
Induction heating can produce high power densities which allow short interaction times to reach the required temperature. This gives tight control of the heating pattern with the pattern following the applied magnetic field quite closely and allows reduced thermal distortion and damage.
This ability can be used in hardening to produce parts with varying properties. The most common hardening process is to produce a localised surface hardening of an area that needs wear-resistance, while retaining the toughness of the original structure as needed elsewhere. The depth of induction hardened patterns can be controlled through choice of induction-frequency, power-density and interaction time.
Limits to the flexibility of the process arise from the need to produce dedicated inductors for many applications. This is quite expensive and requires the marshalling of high current densities in small copper inductors, which can require specialized engineering and 'copper-fitting'.

    We need your machine with similar specs:
    -PVC tube filling & sealing machine.
    - We need price for CIF Dammam, saudi arabia.
    - All electric devices & motors should be 60Hz, & not 50Hz.
    - We need filling volume to be adjusted for 100 - 200 ml.
    - Capacity is good for 30pcs/min.
    - What is delivery time for your induction heating machine?
    - How many filling heads or nozzles in you machine?
    - Can your machine mention batch # & production date while sealing the tube?
