Dongguan LiHua Machinery Equipment Co., LTD is a high-tech private enterprise who gathered researching, designing, producing, selling, service together. The company has many products such as Robot, manipulator, welding, polishing, grinding, metal forming and non-standard automation equipments. The company had passed management certification of ISO9001. Their products had passed safety certification of CE.

The company has independent plant nearly 10000 square meters, the company had successfully provided products and service to hundreds of the well-known domestic enterprises such as Media, Galanz, Supor, ASD, Samick, Jin Jiang, Shun Fa, Shanghai electric, Sheng Yang, Yu Feng, Kang Sheng, Shun Da, Hitachi, Panasonic, Hua Lu and win the reputation.

“Touch China with quality, Touch the world with credit!” is the business idea of the company; the company always pursue the specialization and excellence, and gain the trust and support from customers by advanced technology and mature management; The company had promoted and implemented the quality management idea of “zero defective products”, and established a complete marketing and after-sales service through China.

The company sticks to the principle of “creating the first class quality, establishing the first class brand”; The company aiming on creating profits for customers, and creating value for the society. The company try the best to offer the customers with the best, the latest and the most comprehensive techniques and service.

LIHUA IGBT induction heaters adopt the latest MOSFET, IGBT power units and frequency conversion control techniques with high efficiency, low energy consumption and higher output power. With constant current and constant power control function to greatly optimize the heating process of metals, realize efficient and fast heating, and fully exert the superiority of the products. Power consumption is half of traditional electron tube high frequency induction heating equipments under the same conditions. With 100% load design, can work for continuous 24-hour a day. Infrared temperature detector can be equipped to realize the automatic control of temperature, improve heating quality and simplify manual operation. With heating-insulating-cooling three stages function setting, the heating and insulating time required can be get to accommodate to the batch and repeated heating situations. With multiple status display of overflow, over voltage, low water, phase failure and load malfunction, providing higher reliability and sustainability. Select power supply according to the power and frequency. The higher the frequency, the shallower the heating depth, and the lower the frequency, the better the diathermancy.

The principle of high frequency induction heating is that apply high frequency alernating current to a conduct that is curled to  cyclic (normally copper tube) to produce flux, then put the metal to this area to make the flux to run through it, and eddy current will be generated in the deriction of self-capturing with flux(rotary current), the induced current then generates heat under  the influence of the eddy current, so this heating method is called induction heating. hence, metal and other objects under heated can be heated without contact. at this moment, the character of the eddy current relies in that the induction heating on the object nearby the coil is outwardly strong but inwardly weak. with this principle. this heating body can be concentratedly heated where needed to achieve instantly effect, thereby the production output and work capacity are both improved.
