While reviewing the sources of search keywords on our website today, I came across this query: “What is the maximum magnetic flux density that injection-molded ferrite can achieve?”
I tried searching on Baidu and found two articles from our old website on the first page, but they didn’t actually address the visitor’s question. So today, I’ll discuss the maximum magnetic flux density that injection-molded ferrite can achieve.
The magnetic performance of injection-molded ferrites typically ranges from around 1,200 to 1,300 Gauss, depending on the specific size and specifications. A surface magnetic flux density of approximately 1,500 to 1,700 Gauss can also be achieved.
Multi-pole injection-molded ferrite ring
How high is the surface magnetic flux density of injection-molded ferrites? Here are some sample data from our company’s work for clients for your reference.
1. Radially externally magnetized 10-pole injection-molded ferrite (D40.5 × 28.5 × 26 mm), with an average peak surface magnetic flux density of 1620 GS.
2. Radially externally magnetized 4-pole, D27.80 × 24.85 × 26.5 mm: surface magnetic flux density 1450 GS.
3. Radially magnetized with internal 4-pole configuration, D40 × 31 × 12 mm: magnetic flux density 850–900 GS.
4. Radially externally magnetized injection-molded ferrite, 8-pole, D74 × 62 × 30 mm, magnetic flux density 1750 GS.
Of course, in addition to injection-molded ferrite, we also offer injection-molded neodymium magnets, which have significantly higher magnetic performance than injection-molded ferrite. If you require them, we can provide you with a quote.
