Welcome to Transmart industrial limited, one of the leading magnetic core manufacturers in China.
We are a group company located in Foshan, China, with two manufacturing plants, the magnetic core & transformer production plants covers more than 70,000Sqare meters. We specialized in a broad range of tape wound cores in amorphous metal materials, nanocrystalline alloys, silicon steel core, and mu-metal Nickel alloys, for a wide variety of applications including solar inverters, new energy vehicles, instrument transformers, current sensors, common mode chokes, power supplies transformers. Our main products including soft magnetic materials and toroidal transformers. We also manufacture high-performance components using our high-quality cores made in-house.
One of the key factors to the success of TRANSMART is focusing on basic raw materials research and development. Our ability to tailor the composition and specific heat treatments according to our know-how enables us to design alloys with unique properties for specific customer needs.
Transmart is one of the few companies worldwide that have mastered the rapid solidification process where alloys are being produced as a thin strip to its final thickness of typically 16 to 30 μm.
We tightly control all aspects of our processes. We do our own slitting. we are controlling our products from beginning to end with quality in mind.
The alloy ribbons of large coils are cut to the required sizes using specially developed precision coil slitting machines.
The small cores are wound into toroidal with fully automatic winding machines, while the big cores are wound by semi-automatic winding machines. There are 70 fully automatic winding stations and 30 semi-automatic winding machines at Transmart, with a capacity of winding 100K units per day.
The heat treatment or annealing process represents the cornerstone of the know-how acquired by Transmart. It is the key process that defines the properties of the final core. Some cores need magnetic field heat treatment in order to achieve the values designed. The annealing temperature is 500- 600 °C and the cycle time is longer than 10 hours. Throughout the process, fully automated oven controllers provide real-time monitoring of temperature, atmosphere, and cycle time.
One of the main products at Transmart is tape wound cut cores including C-cores, E-cores, gap cores, split cores, and customized cut cores. Both our plants have 60 high-precision cutting machines, with a capacity of 500,000 pieces per month, being one of the largest cut core manufacturers in China.
Following the annealing process, the cores are being encapsulated or coated to provide optimum protection against mechanic stress. Custom designed fully encapsulation lines shorten the manufacturing time. Cores can be encapsulated in the plastic case, metal case, and insulation materials.
At TRANSMART, every core we manufacture is made to our customer’s exact specification, our engineering system generates customized designs according to electrical, mechanical, and operating requirements. We are certified according to ISO9001, 14001 45001, and IATF16949. We built a state-of-the-art manufacturing facility for automotive products. Our commitment to quality can be seen at each stage of design and manufacturing. The fully automatic production ensures high-quality consistency and transparency.
