Finding a domestic company when sourcing magnet and motor parts is not as easy as you might think. Since most of them are Chinese OEMs or lack specification information, it is easy for the person in charge to feel tired even before making an inquiry. Then I found out about a company called Hellomag, and after looking at their sites one by one, I even made inquiries directly.
Hellomag, what kind of company are you?
Hellomag is a B2B company specializing in magnets and motors located in Bucheon-si, Gyeonggi-do.
CEO Park Deok-gyu's CEO message introduces the slogan "Small but powerful, technology that connects the world" , and we handle a variety of magnet products such as Nd Sintered, Nd Bonded, Nd Injection, SmCo, and Ferrite.
is not a company that simply sells products, but its strengths include understanding the entire process from raw material supply to sintering, injection, magnetization, and quality control, and proposing customized solutions for customers.
Can I actually check the specifications on the site?
When looking for a B2B magnet company, the most disappointing part is product information. In most cases, there is only a “Please contact us” notice and the actual specifications are often not disclosed.
Hellomag was able to find key performance information in relatively detailed detail on the product page.
For example, on the product page of NdFeB Injection Magnet , the Br (residual flux density), Hcj (coercivity), and BHmax (maximum energy) values for each grade are disclosed in table form.. A total of 8 grades are provided from
NI-210L to NI-280L,
- Operating temperature: 80~120℃
- You can also check information such as Nylon12 based material
- insert molding possible
.
SmCo (samarium cobalt magnet) also has a detailed product composition.
- SmCo5 (1:5 series)
- Sm2Co17 (2:17 series)
, maximum operating temperature Products that support 350℃ and temperature coefficients (αBr, βHcj) are disclosed, providing enough information to enable primary review in the aerospace, military, and high-temperature motor fields.
Is it possible to request customization?
At the bottom of each product page, custom grade production tailored to customer requirements is possible. For , instructions are displayed in both Korean and English. The
motor business introduction page also emphasizes , an approach that simultaneously optimizes the magnet design and motor design, so it appears to be a structure that enables development collaboration rather than simple parts supply. When I contacted
directly through online inquiry, the response speed was relatively fast.
We were able to receive a response that specifications could be discussed for small quantity inquiries, and as instructed on the site, we confirmed that both mass production and small quantity development are possible.
Contact information and contact information
- Phone: 010-8990-0603
- Email: parkdockyu@hellomag.co.kr
- Operating hours: 09:00 ~ 18:00
- Online inquiry: Use the inquiry form on the Hellomag homepage
Personally, what impressed me was the operating hours notice.
"Adventure knows no red days."
Although it was a short sentence, it was an element that allowed you to feel the atmosphere in which the company treats its customers.
Which business is Hellomag suitable for?
Hellomag is suitable for:
- Electric vehicle drive motor
- Industrial robot
- BLDC and Servo motor
- Aerospace/high temperature environment parts
- Sensor
- Speaker
- Home appliances
- Industrial magnet applications
Especially for purchasers who want to compare product specifications first and then consult, or research and development teams who need to develop customized magnets rather than standard products. I felt like this was a company worth consulting with.
Overall Review
When looking for domestic magnet companies, there are many cases where there is a lack of data or limited product information. Hellomag's first review stage was quite convenient in that detailed specifications for each product can be found on its website, and it even supports customization and small-volume consultations.
