Misconceptions in the selection of induction heating equipment Misconception 1: Only focus on power, not frequency. When heating standard parts, fasteners, etc., if the diameter of the heated workpiece is greater than Φ 20mm, intermediate frequency equipment should be selected. At this time, using high-frequency machine tools can cause "burning flow" on the outside of the workpiece and "black heart" (commonly known as "incomplete burning") inside, which not only greatly reduces equipment efficiency, but also shortens the life of the mold, and even causes mold damage, unknowingly increasing costs Misconception 2: Only focus on output, not on input. Neglecting device efficiency and power consumption factors, only realizing after repurchasing the device that it is an "electric tiger", resulting in an awkward situation where it can be bought but cannot be used. For example, there are also 80 machines, but one has an input power of 80KVA and the other has an output power of 80KW However, the efficiency of the equipment varies greatly, and although it can also meet heating requirements, the high power consumption has caused users to complain endlessly. The device with an output of 80KW has an input power of up to 120KVA Misconception 3: Only focus on the model, not the power. For example, mixing the single-phase input current of the device with an input power of 120 KVA, collectively referred to as 120 machines, only found that the actual power after repurchase was only 80 KVA, which clearly had the upper hand, but actually suffered losses in secret.

The Ningbo International Automotive Parts and Aftermarket Exhibition is the only export-oriented automotive parts and aftermarket trade exhibition in China. CAPAFIER leverages the trillion dollar Ningbo automotive industry cluster, port, and foreign trade advantages to create a professional service platform for display, exchange, cooperation, and trade, dedicated to helping industry manufacturers expand their domestic and international markets.   The previous exhibition was successfully held from August 16th to 18th, 2023. As the first large-scale exhibition in East China in the autumn of 2023, Ningbo Auto Parts Exhibition has received unprecedented attention from the industry. 1182 high-quality automotive parts manufacturing enterprises from 18 provinces, municipalities, and autonomous regions across the country participated in this exhibition, showcasing over 10000 products from the automotive industry supply chain and after-sales market. The exhibition site was crowded with people, with a total of 26192 visitors in three days, including 379 overseas buyers. Multiple conferences and forums were held simultaneously on hot topics such as automotive new energy and lightweighting, cross-border sales, overseas markets, and digital brand globalization, and the exhibition achieved complete success.   Ningbo Dedao Electronics Co., Ltd. specializes in manufacturing induction heating equipment, quenching machines, heating systems, heating coils, induction brazing equipment, induction forging equipment, induction melting systems and other heat treatment equipment and metal heat treatment services.

  Hardenability of steel After quenching, the structure of steel undergoes martensitic transformation from the surface, with the highest content of martensite in the surface layer, accounting for 97-99%. The deeper the volume of martensite, the less it decreases until it completely disappears. We will increase the martensite content from the surface to 50% As a statistical standard, this area is counted as the hardened layer of steel; The thickness and depth of the hardened layer are used as evaluation indicators for heat treatment performance, known as hardenability. The thickness of the hardened layer of steel indicates its good hardenability; The shallow hardening layer of steel indicates poor hardenability. Therefore, hardenability essentially refers to the ability of steel to harden in cross-section. Ningbo Dedao Electronics Co., Ltd. specializes in manufacturing induction heating equipment, quenching machines, heating systems, heating coils, induction brazing equipment,Our high-frequency quenching machines are engineered to precisely control this hardening depth, ensuring consistent and superior results for your critical components induction forging equipment, induction melting systems and other heat treatment equipment and metal heat treatment services.

Selection Guide for Induction Heating Equipment Choosing the right induction heating equipment is critical to achieving consistent results and maximizing efficiency in your operations Heating type Scope of application Frequency selection Power supply selection   Heat transfer of workpiece Cold heading and hot rolling of fasteners, standard parts, auto parts, hardware tools, rigging, fried dough Fried Dough Twists drills, etc Principle: The larger the diameter of the workpiece, the lower the frequency. For example: above Φ 20, intermediate frequency (1-20KHZ) Φ 5-20, high frequency (20-100KHZ) below Φ 5, ultra-high frequency (100-500KHZ) Choose the appropriate power based on production efficiency. The higher the power, the faster the speed. Please consult the company's technical personnel for specific details   heat treatment Shaft, gear, sprocket, machine tool guide rail accessories, wire annealing, hydraulic accessories, automotive parts, cutting tools and pliers, stainless steel pot annealing, etc Principle: The shallower the required hardening layer for the workpiece, the higher the frequency should be. For example: below 1mm, ultra-high frequency 100-500KHZ; 1-2.5mm, ultrasonic frequency 20-100KHZ; Above 2.5mm, intermediate frequency 1-20KHZ. Considering the shape of the workpiece, quenching method, quenching hardness, requirements for the hardened layer, and materials, please consult the company's technical personnel for specific details.   Brazing Composite welding of different materials, such as drill bits, turning tools, reamers, milling cutters, drill bits, and stainless steel pot bottoms Principle: The larger the welding volume, the lower the frequency. Tools with a volume less than 30 * 30 * 30 can use high frequency; If it is greater than 30 * 30 * 30, use intermediate frequency. This depends on the specific shape, material, solder, and other conditions of the workpiece.   smelt   Precious metals such as gold, silver, copper, lead, etc Medium frequency, small capacity optional high frequency This depends on the furnace and production efficiency.   other Heating film coating for aluminum-plastic pipes, steel plastic pipes, cables, and wires; Aluminum foil sealing is used in the food, beverage, and pharmaceutical industries. According to specific circumstances This depends on production speed, materials, and temperature.   Special functions and supporting equipment Such as dual frequency equipment, multi load matching type (dual head, multi tap), automatic control type, one to two, bridge type oil pipe bending, constant power and constant current, and soft connection sensors.
