HiTek Power operates an integrated quality and environmental management system that meets the requirements of
ISO 9001:2008 &
ISO 14001:2004 and is designed to support the company's quality and environmental policies.
The following management system description, although not exhaustive, gives an overview of some of the key equipment and processes used by HiTek Power Ltd.
First and foremost it is our people that make our quality management system work effectively. The flexibility, skill and dedication of our workforce is the foundation on which all else is built. A full description of our human development process is given on the following link
Working for Us.
The company’s processes have been identified, described (by easily understood flowcharts), refined and, by using various mechanisms/quality tools, continual improvement is achieved. Regular internal and third party auditing is carried out to ensure the management system is operating within required and planned parameters and the whole management system is subject to comprehensive, annual, top management review.
HiTek Power has invested in the latest design tools to help ensure quality is designed into its products from inception.
Mechanical design is carried out using Inventor Autodesk 3D modelling software which ensures tolerance fit errors are avoided. Files of parts used in the models can be electronically loaded into suppliers CNC machines without any significant human intervention, which ensures a more rapid fault-free supply of mechanical components. During the design phase of producing customer specific products, many customers find it beneficial to import the Inventor 3D model into their end system model, this way cabling and other assembly issues can be optimised in their system easily. Manufacturing drawings can also be generated directly from the 3D model, allowing for a more rapid completion of the manufacturing build information package.
Printed circuits are generated using Zuken Cadstar PCB design suite software; Cadstar PCB designs (using enabling software) can be fully imported into the inventor model ensuring full mechanical integration. Spacing matrix parameters for Cadstar are defined by the HiTek Power compliance team, resulting in PCB designs that inherently meet applicable safety standard requirements.
Design use specialist 3D voltage stress modelling software to optimise HV component/assembly designs; ensuring high voltage assemblies meet derating rules and therefore operate within acceptable stress limits necessary for long term reliability.

For design testing product reliability under vacuum arcing conditions (generally significantly more severe than arcing in air), HiTek Power has designed an arc tool that can be used to generate hard vacuum arcs between high voltage outputs and ground. If required, using the isolated electrodes within the arc tool, arcs can also be generated between outputs of differing voltages and/or polarities.

Compliance to applicable safety, EMC, medical, transportation, reliability, environmental and, where applicable, customer standards is a key part of the company's design process. A full description of this compliance process is available on the following link Regulatory Compliance.
HiTek Power uses Fourth Shift™ manufacturing management software for its MRP requirements, with customer orders and sales forecasts placed on this system being converted at the appropriate time into the necessary purchasing information for part ordering or contract call off for the timely build of the finished product.
Through detailed performance feedback and monitoring, HiTek Power works in partnership with its suppliers to maintain and improve quality and delivery performance. The HiTek Power supplier base includes a number of key Chinese suppliers who are used for volume and medium volume production of HiTek Power designed parts, assemblies and products, allowing for competitive pricing to be maintained in this key area.
Once materials are received into the company they are placed into one of the company's four Kardex computer-controlled, automated storage and retrieval carousels. Fourth Shift ™ communicates through enabling software directly with the Kardex carousels, so kitting of parts for production build is uncomplicated, fast and an error-free operation.

A cross-functional, team-based Cell manufacturing system is used for product and sub-assembly build, with quality and efficiency improvements being continuously driven through these cross-functional manufacturing cell teams. As with other process areas, cell process measures, improvement targets and communication/improvement tools are displayed and available within the team working area.
To maintain awareness and focus, brief (typically 10 minutes) daily cell team meetings are held within the cell area - this is so outstanding improvement actions and progress/completion details can be given by the tasked team function member and new opportunities for improvement discussed, with any resulting actions being allocated appropriately within the team.
A final step of the cell meeting process is where the planned daily output is discussed and any necessary actions agreed to ensure that promised customer delivery dates are met.
Testing at various levels (finished product, assemblies or components) is carried out as part of this cell manufacturing process to ensure excellent end product quality.
Comprehensive testing is carried out under controlled conditions against a fully documented and defined process, with specialised test equipment such as X-Ray tubes, e-beam equipment, light sources etc being used where end application test simulation is also required.
For some products testing at elevated temperatures is carried out as part of a final test burn-in process, this is followed by a final calibration check prior to test release.
As part of the product test process and to ensure reliability under severe operational conditions, power supply outputs are arced to ground (usually 100 arcs), with a final overnight unit operation at full output voltage/power (also elevated temperature for some products) being carried out, prior to final calibration and test release.
High accuracy of secondary test DC high voltage dividers is maintained by calibration to the company's master 180kV high voltage divider. This master divider has been constructed using precision wire wound resistors (a zero voltage coefficient and a temperature coefficient of 3ppm) contained within a liquid silicon solution; this master divider has been calibrated by NPL and latterly the Swedish National Laboratory to a high degree of accuracy (<100ppm).

Cell support processes such as encapsulation and coil winding are monitored separately with their own process measures being taken and improvement targets being set - this monitoring, measuring and improvement is the rule for all of the company's processes.
Inspection is carried out within the cell process and prior to final despatch packing, with QC supporting the continuous improvement process by analysis of the process measures for any low level trends that could be opportunities for corrective and/or preventative actions.
After final testing and inspection the finished product is packaged in a packaging system which, as part of the design process, has been specially designed to ensure safe, world-wide customer delivery.
After-sales support is provided to customers through our Service centres in the UK, USA East Coast and Japan. As an indication of product reliability, it should be noted that HiTek Power currently services and updates some products that are more than 20 years old.
Service failure data is continuously analysed for trends by QC, with any opportunities for improvement found being fed into the company’s corrective/preventative action processes.
