Engineering, from idea to production

We develop physical and IoT products end-to-end — and stay with you all the way into stable manufacturing.

Product engineering and IoT R&D in China – CAD and prototype development

Turnkey product development in China

LeWorks provides turnkey R&D services for companies that want to develop reliable, manufacturable products — without building a large in-house engineering organization.

Our engineering team works closely with supply chain, toolmakers, and our own factory to ensure that what is designed can actually be manufactured — at scale and at target cost.

  • Product definition and technical specification
  • Mechanical, electronic, and firmware development
  • Rapid prototyping and testing
  • Certifications, compliance, and testing preparation
  • Patent and IP support
  • Design for Manufacturing (DFM)
  • Tooling, molds, and supplier coordination
  • Manufacturing ramp-up and ongoing engineering support

From idea to stable manufacturing

  1. Concept & specification
    Define requirements, constraints, and success criteria together with the customer.
  2. R&D & prototyping
    Build and test prototypes in our Shenzhen R&D lab, iterating quickly.
  3. Certification & IP
    Support certification planning, testing, documentation, and patent processes.
  4. DFM & supply chain
    Engineers work directly with suppliers, toolmakers, and mold factories — often on site.
  5. Production transfer
    Move the product to our assembly factory with engineering oversight.
  6. Manufacturing support
    Engineers remain involved to resolve issues, optimize cost, and improve quality.

Deep experience in IoT and connected products

We specialize in hardware and IoT product development in China, combining R&D, supply chain, and manufacturing under one team.

Our team has developed more than 20 connected products across consumer, industrial, and infrastructure use cases.

  • Mechanical design for electromechanical products
  • Electronics design and component optimization
  • Firmware architecture and development
  • Integration with cloud and mobile apps (via trusted partners)
  • Cost reduction and China-specific component sourcing

While IoT is our core strength, we also support simpler mechanical or electronic products when needed.

How we work with customers

Every customer is different. We adapt how we work depending on your team, experience, and goals.

  • Full project ownership — We act as your R&D department, with you as product owner.
  • Embedded engineering — Our engineers join your existing team to cover specific areas.
  • Consulting & DFM support — Engineers work directly with suppliers, toolmakers, and mold factories — often on site — enabling effective DFM engineering in China. This local presence is critical for hardware product development in China, where design decisions are tightly linked to supplier capabilities.

Projects are run in an agile structure with clear plans, weekly update meetings, written progress reports, and regular prototype deliveries.

Local where it matters

Prototypes are typically developed in our R&D lab in Shenzhen. When products move toward production, engineering work shifts closer to suppliers and our assembly factory in Changzhou .

Being local allows us to solve problems faster, negotiate better terms, and make informed technical trade-offs that are difficult to manage remotely.

When LeWorks is the right partner

  • You are developing a new physical or IoT product
  • You lack in-house manufacturing or DFM experience
  • You are moving production to China
  • You want one team responsible from R&D through production
  • You need engineers who can work hands-on with factories and suppliers
