Since 1983, JJS has been manufacturing complex electro-mechanical products on behalf of its customers. Our skill sets have continued to evolve. We feel that the full breadth of our precision mechanical assembly capabilities (often referred to as "mechatronics") is unique in our marketplace.
We offer customers integrated contract manufacturing services for highly complex products. Before, these products were often seen as those that could not be outsourced.
We produce many complex mechanical assemblies, which often feature a similar number of parts to a PCB assembly. These products demand high levels of skill, precision, accuracy and consistency. There is considerable in-house experience producing mechanical assemblies. They have such a high level of moving parts that we refer to them as "machines" rather than "products".
The awareness of critical engineering tolerances and the use of mechanical tools and gauges is key when producing moving mechanical assemblies of this complexity. Our skills-base also extends to testing mechanical and pneumatic assemblies. Following rigorous approval processes, our supply chain partners for custom parts - such as plastics, machined and fabricated metalwork, etc. - are monitored for quality and delivery performance. Tight control of the material supply chain ensures that, as with electronic parts, the availability of high-quality mechanical parts is maintained for timely production.
Interactive electronic documentation, dual-language work instructions and robust variant management controls are just some of the lean principles driving our quality-controlled production lines.
We have considerable experience of establishing "lean lines", to produce complex mechanical assemblies. These assemblies can be resourced by between two and 10 operators, depending on live customer demand. We operate 24-hour replenishment through a line-side KanBan-based pull system, which is supported by bar-code tracking to provide real-time operational information.
Many of the assemblies produced by JJS Manufacturing need wire and cable interconnection between boards and sub-assemblies. This can be via cable forms or point-to-point wiring.
As part of our electro-mechanical assembly service, we are often called on to produce machines that require critical cable routing, so that the moving parts may function. We also undertake electrical wiring of switch and instrument panels, as well as sophisticated control cabinets. These are all essential requirements for many of our customers. This activity reflects the same standards of accuracy and consistency as our PCB and mechanical assembly work.
Control software upload, verification and execution is carried out within the scope of JJS's robust revision control system. JJS Manufacturing can provide historical records of hardware and software revisions for specific products and end users on request.
