Our Clare HAL 103 safety tester handles tests up to 6KV AC and DC and ground bonding currents up to 40A. We also use an environmental chamber for temperature and humidity testing. All our test equipment is calibrated annually, ensuring accuracy and reliability.

Flexible Production, Meeting Your Demands

From small-scale prototypes to production runs of 50 to 5000 units per month, we provide a reliable and scalable service to meet your changing needs.

Expanding Our Capabilities to Serve You Better

Recent investments in new machinery and the acquisition of Spring Europe's winding division mean we can now offer a comprehensive range of winding services, particularly for ferrite and small toroidal cores, all tailored to your specific requirements.

Capabilities and capacity

We aim to expand our ferrite manufacturing capacity over the coming years, with the intention of becoming a significant UK manufacturer in this area.

Our capabilities include, but are not limited to, the following:

RM ferrite cores

From RM6 upwards. We can also provide winding with inter-layer insulation for high voltage transformers and twisted multifilar winding to reduce skin effects.

E cores

We can wind all types of E-core, including: ETD,EFD, EE, EF, supplied assembled with any core of your choosing, gapped or ungapped, or supply them to you for self-assembly.
 
E cores can be supplied unvarnished or varnish dipped.

Toroidal inductors, common mode chokes and transformers

Using our pull winders, we can manufacture these to your requirements.

Sizes from 3mm to 50mm internal diameters. Core material types: Iron dust, Ferrite or any particular material to your specification.

Specialist potted audio transformers

Using nickel cores.

Winding services for actuators and customer-supplied bobbins

We can accommodate your specific winding needs.
