The importance of manufacturing process's quality management and final product's quality inspection is self-evident. Quality management of manufacturing process can help manufacturer to reduce scrap rate, thus enhance qualified rate and efficiency. Quality inspection of final products will ensure customers have stable and reliable products. Quality inspection of final products is mainly including dimension, appearance, magnetic performance, and coating performance. Besides relevant professional testing equipment, automatic inspection has become a trend due to its high reliability and cost advantages.

Manufacturing Process

Sintered Neodymium magnet is prepared by the raw materials being melted under vacuum or inert gas atmosphere in an induction melting furnace and processed in the strip caster and thus cooled to form alloy strip. The strips are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in particle size. The powder is subsequently compacted in an aligning field and sintered into dense bodies. The blanks are then machined to the specific shapes, surface treated and magnetized.

FAQ

Can magnets be exported	Sure. Now we can independently approve licenses, and the delivery time has been increased by five times
Do your magnets support customization?	Yes. We can customize material, size, magnetic strength, plating and special-shaped structure to meet personalized needs.
How to choose different material magnets?	- Neodymium iron boron: Strongest magnetic force, suitable for precision equipment; - Ferrite: Cost-effective, suitable for home appliances and toys; - Samarium cobalt: High temperature resistant, suitable for industrial high-temperature scenarios; - Alnico: Good stability, suitable for instruments.
What is the function of magnet plating? Which has good corrosion resistance?	Plating is used for rust and corrosion prevention. Corrosion resistance order: Electrophoresis > Nickel-copper-nickel plating > Zinc plating > Color zinc plating, which can be selected as needed
Is there a minimum order quantity (MOQ) for bulk purchases? What is the lead time?	MOQ for standard products is 1000 pieces, MOQ for customized products is 5000 pieces (negotiable); Lead time for standard products is 7-15 days, and for customized products is 15-20 days.
