MARND manufacturing process starts early with a cyclic loop of prototyping and design optimisation, followed by preproduction samples manufacturing and test deployment. After the product performance is satisfactory to all stakeholders, relevant manufacturers are surveyed for matching capabilities and suitable ones are selected for the product supply chain. Manufacturing is then managed up until quality control is done and products are dispatched.
Review and Optimisation
Test results throughout prototyping cycle are reviewed to highlight challenges and areas for improvement. The design is then either improved through modification or is redone from scratch to provide maximum improvement.
This process is cyclic in nature, and usually require repetition of prototyping and test cycle, as well. The process can theoretically be done for an infinite number of times as improvement is always the outcome. However, practical projects require the design to be frozen once the improvement between cycles goes below a relatively low percentage.
Technical drawings are documents that highlight important controlled dimensions for main features, e.g. interface features. They are universally understood and clearly communicate product specifications, e.g. dimensions and tolerances, to manufactures regardless of their experience, language or geographic location.
These drawings are particularity important, since they are usually produced in PDF format that is easily printable by most manufacturers and does not require any specific engineering program to review. These drawings are crucial elements in the manufacturing process, since they are used as a legal document to imitate manufacturing, as a control document to manage manufacturing, and finally as qualifying document to verify manufactured parts.
The first preproduction sample is made based on technical drawings. This help verify product functionality, specifications, and aesthetics. Additional improvements required can then be fed again into a design review and optimisation loop and a new preproduction sample is produced, accordingly. These samples are very crucial. Although they are relatively expensive compared to the mass produced product, they usually save tens to hundreds of thousands of euros in production setup modifications.
Supply Chain Setup
The product is divided up into multiple set of parts based on required manufacturing processes and parts materials. Manufacturers capable of manufacturing each set are contacted from MARND’s shortlist, reasonable offers are compared and manufacturing decision is finalised.
The supply chain is monitored using online progress monitoring and on-site checks to ensure production progression. Continuous communication is maintained to ensure challenges are solved in a timely manner. Manufacturing micro processes are continuously reviewed to maintain quality production and avoid challenges at the assembly line. The assembly line setup is reviewed for improvements and quality maintenance.
Final parts and assemblies are reviewed for conformity and performance. Dimensions are checked for consistency and the products specifications are verified. For most new products non-confirming units can be a significant percentage. These are replaced by supplementary production to achieve required number of units. Product patches that pass quality control tests are packaged and shipped according to requirements.
