Design and Development Our team of R & D engineers have acquired great experience in the design, development and technical analysis of all types of transformer, sensors, mutual inductors and power modules. We can design, test and ship initial samples within one week after customer design confirmation.

Mechanical and electrical development team
All the main machines and equipment in our production facility were designed and built by our own R & D team. We have so far 10 automatic core winding machines and 200 Annular coil winding machines for different sizes of toroidal transformers. Our capacity is more than enough to meet customers various requirements.

Iron core production equipment
‧Silicon steel slitting : Slitting velocity = 30 Tons per day
‧Core winding : We can produce the cores with heights from 8mm up to 110mm, and with outer diameters from 20mm up to 450mm using automatic high-speed precision twin-axle core winding machines.
For an example of our production speed – we can produce an 80mm diameter iron core in just 30 seconds.
‧Core stress-relief annealing : Our cores are heat treated in Bell-shaped covered furnaces, thus increasing production efficiency and quality.
‧Resin-soak hardening : Our core winding techniques produce an excellent base for high electrical insulation. A resin-soak hardening process fills any gaps between core windings, thus producing an even high electrical insulation plus additional mechanical strength.

Coil winding equipment
With more than 200 coil winding and forming machines we can produce inductors and transformers with diameters from 20mm up to 450mm. We are able to provide different structures such as Multi-filar winding, Lap winding and Attach-Detach winding.

Testing Equipment
Along with our 50 winding counter machines and a wide range of additional testing equipments, our highly trained laboratory technicians perform: humidity tests, pressure tests, temperature-rise tests and ageing treatment tests.

Production capacity
Our current production capacity is 500,000 pieces per month. Our production planning department needs only 60 days to increase this level by 30%, and we currently plan to increase our future capacity to 1.5 million pieces per month to satisfy our customers increasing demand.

Dinkle is ISO 9001 accredited and we have constructed a comprehensive management system that controls all aspects of our operations.
All of our materials and components are approved to international standards and are supplied by accredited manufacturers.
All of our products are tested and approved by UL and VDE and our processes are strictly controlled so that these approvals are maintained.

Goods-in materials inspection
All incoming raw materials and components supplied to us are thoroughly tested against our strict specified requirements.

Based on customer specification requirements, UL and VDE accreditation has been attained and our QA test laboratory performs specific test procedures to check that we maintain the necessary high standards to keep the accreditation.

The feature of Toroidal Transformer ‧High Efficiency : Can be up to 50% smaller in height and weight compared to E-I transformers. ‧Energy Saving : The reduced material required for Toroidal transformers results in less production time and thus less energy usage. ‧Light : The Toroid is the optimum design form and thus reduces material usage and therefore the required weight of the transformer. ‧Small : Up to 40% smaller than E-I transformers, thus allowing customers to produce smaller equipment designs. ‧Variable Dimension : The flexiblity of the core dimension design accommodates with various size of product installment space. ‧Ease of Mounting : Various mounting methods to suit all application requirements. ‧Low noise : Toroidal core construction reduces air gap possibilities and thus acoustic hum. ‧Low Magnetic Flux Leakage : Produces less leakage compared to E-I and R-Core tramsformers.
