Custom Magnets and Assemblies


HangSeng Magnetech specializes in custom magnet, magnetic assemblies and customised magnetic solutions production with quick and accurate turnaround. We can driving cost improvements through design.

We are the perfect partner for innovative businesses looking to maximise performance, improve design and reduce costs. We have the expertise to tackle the most challenging of magnetic applications, working with clients to understand their project then design develop and produce a value adding solution.

Having the full package of services in-house gives us full control over costs and planning thereby ensuring we deliver projects on time and within budget.

Manufacturing capacity: HangSeng Magnetech can produce custom magnets and assemblies in large volumes and retain inventory for just in time delivery, as well as small one-off projects.

Lead time: Normal lead time for custom magnets and magnetic assemblies is 5-6 Weeks. Normal lead time for custom plastic or metal assemblies is 6-7 Weeks.

We do more than just magnets: HangSeng Magnetech can also produce plastic or metal parts with embedded magnets. Save time, money, and frustration by producing the entire product with one supplier. HangSeng Magnetech can also offer retail packaging.
