Domestic electronic scale is Chartrick's flagship product line. Driven by corporate strategy, intensive research and development programme was carried out in past few years. After lengthy and persistent effort, Chartrick has been able to command relevant core technology and suppress prime cost effectively. Key upstream components, such as sensor, injection parts and chips bonding, are all done in-house. Other manufacturing services, like electronic circuit design, product design, plastic injection, PCB component assembly, tooling, stamping, spray painting, silkscreen printing and product assembly, are also self-sufficed.
