Product design & development, tooling, manufacturing, component assembly & testing
Miniature wound coil components and assemblies are utilised by clients across a huge range of sectors, both in the UK and internationally, from household goods manufacturing to the oil and gas sector.
Integrated into production lines, forming part of larger assemblies and powering cutting-edge innovation, precision electro-magnetic wound coil components, transfomers and solenoids are essential to the smooth operation of commercial businesses, utilities supply and the development of exciting new technologies.
Experienced product design has supported the development of reliable wound coil miniature components for our client organisations which are capable of scalable production entirely in-house by OF Bell.
Complex miniature components and assemblies include a wound solenoid coil used in carpet weaving, supporting the accurate reproduction of patterns through weaving machinery sensors which identify the threads required to create the end product.
Other wound coil components and assemblies include self-supporting coils created using self-bonding wire to hold their shape, used in sensor assemblies to analyse strength in suspension cables, prototype wound coil components featuring multiple windings to be used as pipeline sensors in the oil and gas sector, and miniature wound coil components assembled by OF Bell in plastic casings and utilised globally as oil and gas pipeline pigging sensors.
Each wound coil component has been engineered by our team, manufacturing processes developed to support ongoing production every month including bespoke tooling for injection moulding of casings and bobbins, and assembly and testing undertaken by dedicated, and highly skilled, technicians to deliver reliable, consistent and functional components which go straight into operation.
OF Bell’s in-house tooling, injection moulding, electrical assembly and testing facilities deliver miniature wound coil components efficiently through a seamless manufacturing process that’s quality-assured throughout.
Specialist equipment, tailored to the commercial production of complex miniature wound coil components, includes coil winding facilities that support 3000 turns of 0.025mm wires per component, produced in volumes of around 1000 per month and wound onto plastic moulded bobbins created in-house with a shot weight of 0.3g.
Wound coils are individually tested for resistance and voltage before assembly into casings. Overmoulding seals each unit before full testing of complete sensors prior to dispatch. Testing certificates are supplied with each sensor to ensure traceability and for our clients’ reassurance that components are ready to get to work.
Excellent production capacity, quality-monitored in-house processes and years’ of electrical engineering expertise support OF Bell’s consistent delivery of complete, fully-tested miniature wound coil components each week to client locations in the UK and worldwide, including the USA and Canada.
