High frequency induction heater introductionÂ
HF induction heating equipment from 15-70KW with oscillating frequencies ranging from 30 to 100KHz. These machines are our earliest models and have been widely used due to their simplicity and affordability. The machines of this frequency range are suitable for applications such as brazing, forging, and heat treatment. Examples include diamond blade brazing, machining tool brazing, rod heating for forging, copper tube brazing, shaft quenching, and stainless steel vessel annealing. Power ranges from 15-70KW, making them the simplest, most affordable, and reliable options in our induction heating machines. They are extensively used across various metal heating applications both in China and abroad.

Metallic Frame TentA metallic Frame Tent has a sturdy and durable frame which is made of metal poles or tubing. Normally, the frame materials are stainless steel tubes or alloy and aluminum tubes, which can withstand wind and rain, even heavy snow, making it a reliable shelter in various weather conditions. The frame can provide the tent with structure and support, allowing it to stand upright without the need for guy ropes or stakes. This type of tent is typically larger in size and is often used for various fields such as field hospital, rescue purposes, fire fighting, military operations and disaster relief. Various sizes and colors are available for different fields of use. The metallic frame tent can provide a more comfortable and spacious shelter. The tent fabric is usually made from durable materials such as canvas, oxford, PVC fabrics or polyester, which are waterproof and UV-resistant and can withstand harsh weather conditions, ensuring that the interior remains dry and protected from the sun's harmful rays.
