Company Profile


Why Choose Us


KAHOOLI provides full service from design, prototyping, pre-production run to volume production. Our engineers have combined more than 20 years of experience in designing and manufacturing magnetic components from medical to military applications. Inductors, chokes, coils, and transformers are designed with laminations, tape would cores, amorphous cores, nanocrystalline cores, ferrite cores, iron powder cores, MPP cores, sendust or high flux cores in all shapes and sizes.


Inductors, chokes and transformers are done at our facility in Shenzhen.Volume productions are done at our ISO 9001 manufacturing facility in Gaozhou and Dongguan to reduce cost.With prototyping and pre-production done in Shenzhen,we can offer our customer the fastest delivery where lead times are critical.Typical delivery from design to pre-production ranges from 3 days to 2 weeks.For volume production manufactured in the Gaozhou, delivery time can be significantly reduced at a higher cost.For high volume production, our prices are one of the most competitive in the market place.Our prices are factory direct with very low overhead allowing us to the savings to our customers.For volume productions, we will beat our competitors' prices.Most of our business come from referrals from our satisfied customers.


Our team of experts can help you with your entire coil winding, inductor, choke, coil and transformer design needs. We will wind anything per your requirements. We have the capabilities to verify your designs, test your ideas and concepts, as well as build your magnetic products to your specifications. We welcome your samples and will manufacture according to your sample configurations to match performance and specifications.


We have over 6,000 different types of raw materials and wires to select from when making a coil, choke, inductor,transformer. We have both manual equipment and sophisticated winding machines to handle any job, large or small.Our operators are specially selected and trained for winding delicate and extremely thin wires on miniature cores.We also have operators who have been specially trained to manually wind heavy gauge wires.Some of our equipment are custom designed to test specific parameters such as flux density, permeability of materials, B-H curves, DC bias, etc. We can varnish, vacuum impregnate, and encapsulate your entire winding jobs.We use soft epoxy materials to ensure that the stress on the cores is minimized to maintain its inductance, Q, and losses.
