DESIGN FOR MANUFACTURE
MASS PRODUCTION
Once the prototyping and testing process is complete, the final product is ready for transition into mass production. By thoroughly testing and refining the product during the previous stages, companies can confidently move on to large-scale manufacturing without any major setbacks or delays. By utilising various prototyping methods and conducting extensive testing, companies can ensure a smooth transition from concept to production, resulting in successful mass-produced products. So, the process of integrating design into production is an iterative and collaborative one, ensuring that the end product meets all the essential quality, performance and regulatory requirements while still ultimately exceeding customer expectations.
This level of attention to detail is what sets successful companies apart from their competitors, making prototyping and testing an essential aspect of any product development process. This approach also allows for continual improvement, ensuring that products stay relevant and competitive in today’s constantly evolving market.
SUPPLIER SOURCING
A critical aspect of design for manufacture is selecting the right suppliers for your product. This involves evaluating potential suppliers based on factors such as cost, quality, and delivery time. It is important to establish a good relationship with your suppliers, as they will play a crucial role in the success of your product.
DETAIL DESIGN DEVELOPMENT
This involves refining the product design to ensure efficient and effective production. It’s the stage where considerations such as material selection, manufacturing processes, and assembly methods come into play. The detailed design and development phase translates a high-level concept design into a detailed plan for volume manufacture. During this phase, specifications are checked, subassemblies are defined, and parts are checked and assembled. Individual parts are finalised, technical calculations are made, and conformity with standards is ensured. Support documents are prepared and reviewed. The goal is to create a design that meets functional and aesthetic requirements while being easy to manufacture.
3D PRODUCTION DATA
In addition to 2D drawings, the production process also requires 3D data. This includes CAD files that allow for the creation of moulds, tooling and other necessary components. This data is crucial in accurately representing the design and ensuring consistency between different parts of the product. It is also used for quality control during production. Manufacturers use specialised software to read the 3D data and produce a physical product based on this information.
2D ENGINEERING DRAWINGS
2D engineering drawings are technical documents that provide detailed information about the product design and individual component parts. The main purpose of is to serve as component control drawings. The vast majority of physical parts specifications are normally contained within 3D CAD data files. These 2D drawings focus in on the critical dimensions, tolerances, and other specifications that are necessary for controlling production. They serve as a universal communication tool between designers, toolmakers and manufacturers, ensuring that everyone is on the same page when it comes to producing acceptable parts that will achieve an agreed quality of product.
QUOTATION PACKAGES AND BILL OF MATERIALS
Quotation packages provide detailed information about a product’s design and specifications, allowing manufacturers to accurately quote the cost of production. This includes 2D drawings, 3D production data, and the BOM. These packages are crucial for obtaining competitive pricing from different manufacturers and selecting the most suitable one for your product.
The BOM is a comprehensive list of all the components, subassemblies, and materials needed to manufacture a product. It includes not only the item names but also their part numbers, quantities, and descriptions. The BOM is essential for tracking the different parts during the production process and ensuring that all necessary components are available. It also helps to identify potential cost-saving opportunities by analysing the materials used in the product.
STANDARD OPERATING PROCEDURES
SOPs provide detailed instructions on how to perform specific tasks within the manufacturing process. They ensure consistency and quality in production by outlining the necessary steps, materials, and equipment needed for each task. SOPs are continually reviewed and updated to improve efficiency and reduce errors in the production process.
PRODUCTION SUPPORT
Design for manufacture also involves providing support during the production phase. This may include troubleshooting issues, clarifying design specifications, or making adjustments to ensure successful production. Production support is crucial in maintaining a good relationship with manufacturers and ensuring that your product meets the necessary quality standards without compromising the products performance, features and customer benefits.
INITIAL TOOLING TRIALS AND PARTS APPROVAL
Before mass production can begin, initial tooling trials and parts approval are necessary. This involves testing the tools and equipment used in production, as well as producing a small batch of parts to ensure they meet the required specifications. Any issues or adjustments needed are addressed at this stage to avoid potential problems during mass production.
Design for manufacture encompasses various stages and elements, all working together to create a high-quality product at an efficient cost. By considering these factors during the design process, manufacturers can produce products that not only meet functional and aesthetic requirements but are also easily and cost-effectively produced.
