Frequently Asked Questions (FAQ)
Q1: How do I choose the right magnet manufacturer in the UK?
Start by identifying your application needs—whether it's industrial automation, filtration, medical devices, or display systems. Look for manufacturers that specialize in your sector and offer certifications like ISO 9001 or industry-specific standards (e.g., HACCP for food safety). Also consider technical support, design capabilities, and lead times.
Q2: What certifications should I look for in a magnet supplier?
For industrial use, ISO 9001 (quality management) and ISO 14001 (environmental management) are baseline certifications. Additional ones to look for include RoHS, REACH, and CE compliance. Suppliers like MainRich, Bunting, and Eclipse all hold these credentials.
Q3: What’s the benefit of working with an international supplier like MainRich with UK operations?
You get the cost advantages of global manufacturing with the local responsiveness of a UK-based supplier. MainRich, for example, offers engineering consultation, fast sampling, and local logistics to streamline timelines and reduce communication barriers.
Q4: Can I request custom magnet designs or prototypes?
Yes. Most top-tier manufacturers—including MainRich Magnets, Goudsmit UK, and Magnosphere—support full custom design services, from CAD modeling to magnetization testing. These services are ideal for motors, robotics, or specialized fixtures.
Q5: What’s the minimum order quantity (MOQ) for industrial magnets?
It varies. Some companies offer low MOQs for prototyping or R&D projects (e.g., Polarity Magnets, Magnet Store), while others specialize in bulk or OEM-scale supply. MainRich offers both low-MOQ testing options and scalable volume production.
