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. Prototype and sample quantities, tooling and charges are confirmed for the proposed process.

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.

Sample availability, quantity, freight, tooling charges and any production-order credit are confirmed in the quotation. Include the grade, dimensions and evaluation purpose when requesting samples.

Payment method, deposit, balance and credit terms are agreed in the quotation and order confirmation. Share any purchasing requirements with the inquiry so the proposed terms can be reviewed.

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 can discuss unmagnetized supply and magnetization in the final circuit.

NdFeB usually needs corrosion protection. Select coating from humidity, chemicals, temperature, tolerances and assembly requirements, then agree validation. A coating name alone does not establish medical, marine or vacuum suitability. SmCo, ferrite and AlNiCo often need no corrosion coating, subject to the application.

Sintered magnets are brittle, so mounting holes and other features require a manufacturability review. Grinding and specialist cutting may be needed. Threads are usually provided by a housing or backplate; bonded-magnet machining depends on the formulation.

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 — with any missing operating conditions identified during the review. The Material Specifications page is a good starting point.

Published planning references are 7–15 days for standard shapes, 15–25 days for custom shapes, and 20–35 days for assemblies. Freight references are 5–7 days by air and 25–40 days by sea to US/EU ports. Confirm material availability, tooling, sample approval, order quantity, destination and transport conditions for an order-specific schedule. Buffer-stock arrangements are discussed by program.

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.
