High frequency induction heater introductionÂ
HF induction heating equipment 15-70KW with oscillating frequency from 30 to 100KHz, these machines are our earliest models and have been used most widely now because of their simplicity and low price. the machines of this frequency are suitable for brazing, forging and heat treatment and a lot of other applications. For example: brazing of diamond blades, brazing of machining tools, heating of rod for forging, copper tube brazing , shaft quenching and stainless steel vessel annealing and so on. Â Power range of HF series induction heating equipment from 15-70KW, machines are the simplest, cheapest and most reliable types in our induction heating machines, they have been widely used in all areas of metal heating both in china and abroad.

Model explanation:
HF-XX AB:
HF-high frequency series induction heating machine
XX-- rated input power or oscillating power
AB-additional function  A: with timer function  B: split type that is with separated transformer
Advantages of timer function:
heating power, retaining power, heating time, retaining time and cooling time can be preset and adjusted, this makes it possible to control the heating curve and heating time.
it is suitable to use in the repeated heating or high speed heating of small parts.
when using in brazing, with proper timing parameters, rapid heating and retaining can be achieved to keep the temperature while the brazing material is melted and then to let the brazing
1. It can be used for a long time at 100℃ and can withstand high temperature bacteria treatment at 121℃. It has outstanding moisture-proof performance and reliable hygienic performance. It is widely used in food packaging. With excellent folding performance, it can be made into stationery clips, boxes, etc.
2. If classified according to the performance of the material, it can be divided into
Common materials, environmental protection materials, cold-resistant materials, anti-breaking materials, conductive materials and anti-static materials, etc.
3. If classified according to the effect of the product, it can be divided into
Transparent materials, color materials, gold-plated materials and flocking materials, etc.
4. Density 0.96~0.98g/cm
Anti-static materials usually use PVC, PP, PS and PET materials, of course, PE materials can also be used; conductive materials usually use PP, PS and PET materials; and flocking usually use PVC and PS materials.
Flocking (flocking) materials and products:
Flocking (flocking) material is a kind of material that has been used more in recent years. It mainly uses PVC and PS materials as the negative film, and planting various colors of fluff on the sheet. It is mainly suitable for some relatively noble, beautiful and generous products (such as cosmetics). Inner support, mobile phone inner support, foreign wine inner support, glasses case, etc.).
