Frequently Asked Questions

For standard shapes and grades, MOQ is typically a few hundred pieces — often less. For custom shapes requiring new tooling, the practical minimum is usually 1,000–5,000 pieces depending on size. Prototypes and samples are always possible without MOQ.

Standard quotes are typically prepared within a few business days of receiving your drawing. Quotes requiring engineering review (assemblies, unusual grades, special testing) take longer — always with a clear explanation of any recommendation we make.

Yes for standard catalog shapes — you pay only shipping. Custom prototypes are charged at a modest tooling and setup fee that we credit back on your first production order in most cases.

First orders: T/T with 30% deposit and 70% before shipment, or full L/C at sight for larger contracts. Established customers move to net terms negotiated per program. We also accept trade assurance platforms for buyer protection.

A drawing with dimensions and tolerances, material/grade (or the application and we'll recommend), magnetization direction, coating, quantity, and target price if you have one. PDF or STEP files both work. The more context you give, the sharper the quote.

Standard ground tolerance is ±0.05 mm; precision grinding reaches ±0.02 mm on functional faces. Bonded (pressed) magnets hold ±0.05–0.1 mm as-pressed with no grinding. As-sintered faces are ±0.1 mm or looser — put tight tolerances only where they matter and save cost.

Yes — we magnetize to any standard pattern (axial, diametral, radial, multipole) before packing. Charged magnets ship under IATA-compliant packaging with the required documentation. If your process prefers uncharged magnets for safer handling, we ship them magnetized-never and you magnetize in-circuit.

Yes. NdFeB contains iron and will rust in humid air without protection. Ni-Cu-Ni covers most applications; epoxy for outdoor/marine; Parylene for medical; phosphate for vacuum applications. SmCo, ferrite, and AlNiCo generally need no coating.

Sintered NdFeB, SmCo, and ferrite cannot be drilled or tapped — they're ground only. We create mounting features with steel backplates, housings, or adhesives. Bonded NdFeB is machinable and can be drilled. Our design guide explains the options in detail.

Send us the application: the force or flux you need, the temperature range, the environment, and the space you have. Our engineers will recommend the grade with proper demagnetization margin — usually within one email exchange. The Material Specifications page is a good starting point.

Standard shapes: 7–15 days. Custom shapes: 15–25 days including tooling. Assemblies: 20–35 days depending on complexity. Air freight 5–7 days door to door; sea freight 25–40 days to US/EU ports. We hold buffer stock for repeating programs on request.

Standard: material certificate of conformance and dimensional inspection report. On request: flux measurements per sampling plan, BH-curve data, salt-spray reports, RoHS/REACH declarations, and PPAP-style documentation for automotive and regulated programs.

We export to 15+ countries, with the United States, Europe, and Russia as primary markets. All export documentation (commercial invoice, packing list, CO, MSDS for charged magnets) is prepared by our in-house trade team.

Yes — we sign NDAs routinely and keep customer drawings segregated. Exclusive tooling agreements are available so your custom shapes are never offered to another buyer.
