JNDC is your design for manufacture partner to increase product quality, reduce risk and cost ensuring products are optimised to meet your Manufacturing needs.

Who we are

JNDC’s core skill set is “Design for Manufacture.”  Quite simply the designs we engineer are aligned to the most fit for purpose manufacturing process, in the material that performs to the products specification.  Time, quality and cost are the three key elements to consider throughout the design for manufacture stage.  A detailed plan and product specification are a critical entry gateway to ensure these three key elements are fully understood.  

Our history


For over 10 years JNDC has been working with its customers to design, develop and produce products ready for the market.  We started our consultancy working for major aerospace companies, assisting in designing products to optimise the assembly of aircraft structures.  Over time our design skills were recognised outside the aerospace industry, so we expanded our offering into other industries, taking all of our aerospace design for manufacture knowledge across into a wider field. 

As we migrated into other industries we discovered JNDC has a unique offering off applying specialist design for manufacture skills into virtually any industry.  We have worked on projects from aircraft seats to medical devices, from folding bikes to mobile phone cases. 

In the last few years we have found a very large demand for our skills and experience in business to business and retail products. All of our projects follow very simple stages resulting in a final product that is truly aligned to our customers needs.

How we work: new product development


Planning is the first of four stages that produces clearly defined progressive stages throughout the project.  Before we jump into the engineering detail, we take a step back and undertake a design & project review which allows JNDC and our customer to investigate and plan the project in detail to ensure the final product meets the specification. By defining a detailed specification JNDC is then able to move forward onto the following stage of initial development.

Specification Development

We work with our customers to develop a fully defined product specification.  

Project Planning

Based on our experience of managing design for manufacture projects, we work up a detaild project plan, identifying and mitigating rick throughout the project.

Project Costing

The product specification and project plan are combined and reviewed to detail the costs from initial design through to production. 


Stage 2: Initial Development

The initial development process typically utilises our skills in Computer Aided Design, creating three dimensional models to communicate with our customers allowing them to see how the product will look and operate.  Our expert materials, prototyping, testing and engineering knowledge allow us to prototype and test the product before going into the next stage of detailed design for manufacture. 


Initial Design

From hand sketches through to CAD modelling, we develop the design based on the output of the planning stage.


Utilizing a vast range of prototyping processes, we convert our initial designs into a physical prototype, enabling our for the customers, for the first time to see their physical product.

Testing & Review

Initial testing of the prototype is critical at this early stage to ensure the initial design meets the product specification. At low cost, changes to the prototype can be made, confirming the design meets the secification.


Stage 3: Detailed design for manufacture

JNDC’s core skill set is “Design for Manufacture.”  Quite simply the designs we engineer are aligned to the most fit for purpose manufacturing process, in materials that perform to the products specification.  Time, quality and cost are the three key elements to consider throughout this design for manufacture stage.  


Engineering design for manufacture

We use the latest state of the art computer aided design tools to develop 3D models of all parts, components and assemblies allowing us to check the design before final preproduction prototyping.

Pre production prototyping

Our skills and experience in pre production prototyping enables us to create advanced prototypes, mimicking the final product, without the need for production tooling and processes.

Final testing and certification

Final testing of the pre production prototype ensures the product preforms to specification before going into production, significantly reducing the risk of needing to make changes to final production parts.


Stage 4: Manufacturing & Production

JNDC has managed the manufacture of its designs in the United Kingdom, Europe and China.  Being on the factory floors observing the tooling and parts being produced has promoted a specilist understanding of the subtleties in design that are required to deliver a product that is truly aligned to a manufacturing process, on time, to quality, at the target unit price.


Part manufacture

JNDC manage our suppliers and manufacturers to ensure parts are made on time, to the correct quality and cost. 


We work with the manufacturers to design and create an assembly line with all the necessary quality checks being undertaken through the assembly process, resulting in consistent products being produced to specification.

Ongoing Production

With production samples signed off, we continue to work with the manufactures during ongoing production runs to optimise the manufacturing and assembly process.

How we work: existing product relife

Some of JNDC's customers already have a product in manufacture with a specific need to adjust the design or manufacturing process to resolve issues.  From the start of the project our customers are usually experiencing a problem with either lead time for the product, in service quality issues, or, the cost of the product being produced is not meeting the needs of our customers business. 

JNDC’s approach is to first step back, undertake a design & project review  to unpeel the layers of information to determine the root cause of the “issue”.  With the root cause identified JNDC workswith the customer to ensure the product in manufacture will meet all of the detailed specifications of time quality and cost.

We follow a very similar methodical process to the "New product development" working progressivly through the project yeilding a product that has been revived and refreshed.
