Rigorously tested rare earth magnetic assemblies customized for automotive, heavy industrial automation, and machinery applications across Romania.
As the primary industrial, economic, and technological engine of Romania, the greater Bucharest-Ilfov metro region is experiencing unprecedented modernization. From high-tech automotive component production and electric vehicle (EV) powertrain R&D around Mioveni and Pitesti to modern logistics centers along the A1/A3 corridors, the demand for precision magnetic assemblies has expanded significantly.
Zhejiang Laysun Magnetics Ltd. serves as a direct manufacturer and global supply chain partner, delivering custom-engineered rare earth Neodymium-Iron-Boron (NdFeB) magnetic assemblies directly to manufacturing enterprise clients operating in Bucharest and surrounding industrial hubs.
Information Gain Insight: Raw magnets often fail in industrial operations due to brittleness, flux leakage, and poor corrosion resistance. Engineered magnetic assemblies solve this by encapsulating sintered NdFeB inside precision steel housings, boosting holding force by up to 500% while offering superior mechanical protection.
Established in 1999, Zhejiang Laysun Magnetics Ltd. operates state-of-the-art rare earth production facilities focused on custom magnetic circuit engineering.
We utilize ANSYS and Maxwell 2D/3D simulation software to optimize magnetic circuit flux density, ensuring maximum holding power and zero unwanted electromagnetic interference for Bucharest automotive and aerospace systems.
By substituting heavy rare earth elements (Dysprosium Dy / Terbium Tb) into grain boundaries, our high-coercivity NdFeB grades (SH, UH, EH, AH) withstand operating temperatures up to 230°C without demagnetization.
Offering Ni-Cu-Ni, Black Epoxy, Thermoplastic Rubber (TPV/TPR), PTFE, and Passivation coatings capable of enduring 96 to 500+ hours of continuous salt spray testing (ASTM B117 standards).
Selecting the appropriate magnet assembly for heavy industrial or precision automated applications in Bucharest requires an in-depth understanding of magnetic physics, thermal constraints, mechanical force vectors, and localized environmental factors.
Unlike raw sintered NdFeB blocks, magnet assemblies utilize ferromagnetic flux-shunts (such as mild steel pots, back-plates, or stainless steel casings) to redirect and concentrate magnetic field lines. This dynamic dramatically increases magnetic flux density ($B$) at the active working contact face while insulating non-functional surfaces.
When sourcing custom magnet assemblies for South-Eastern European climates and industrial plant environments, thermal stability is critical. Standard N35-N55 grades degrade under high ambient temperatures, leading to irreversible magnetic loss.

At Zhejiang Laysun Magnetics, quality is not just a slogan; it is embedded in our ISO 9001, ISO 14001, and IATF 16949 certified production system. Every production lot destined for Bucharest undergoes rigorous non-destructive and destructive testing prior to export clearance.
Get expert answers regarding technical custom engineering, minimum order quantities, and delivery schedules to Bucharest.
Standard prototypes are engineered and dispatched via express air freight within 7–10 days. Full-scale production batch orders sent via sea freight to the Port of Constanța usually arrive within 25–35 days total lead time including customs processing.
Pot magnets enclose the fragile NdFeB block inside a steel casing. This steel casing shunts the internal magnetic flux to concentrate maximum force onto a single active surface, offering significantly stronger holding force while preventing brittle cracking or chipping.
Yes. We manufacture custom rubber-coated pot magnets with external studs, internal female threads, threaded necks, or countersunk central bores according to your exact ISO/DIN technical drawing specifications.
Absolute compliance is guaranteed. All materials, adhesives, metallic coatings (Ni-Cu-Ni), and rubber protective boots comply 100% with EU REACH SVHC regulations and RoHS directives for heavy metal restrictions.
