Design for Manufacturing and Assembly (DFMA)
Optimize Designs and Reduce Production Costs
We integrate Design for Manufacturing and Assembly (DFMA) from the start of a project, optimizing designs to streamline production, reduce complexity, and cut costs. By addressing challenges early, we improve efficiency, shorten lead times, and deliver precise, cost-effective products to market.
Early Integration &
Collaboration for DFMA Success
Implementing DFMA from the conceptual phase, while fostering close collaboration between designers, manufacturers, and suppliers, is key to ensuring cost-effective, scalable production. By involving the manufacturing team early in the design cycle, we identify potential production challenges such as material limitations, tooling complexities, assembly difficulties, and supply chain constraints before they arise. Cross-functional design reviews further ensure alignment, enabling us to simplify part geometries, optimize materials, and reduce assembly complexity. This integrated approach minimizes costly revisions, cuts down lead times, and delivers high-quality products ready for the market.
Key Benefits:
-
Reduced Part Count: Simplifying assembly and lowering manufacturing complexity.
-
Standardized Materials: Leveraging widely available, high-performance materials for cost efficiency and supply chain resilience.
-
Minimized Manufacturing Steps: Reducing processing steps for faster, more efficient production.
-
Cross-Functional Design Reviews & Continuous Feedback: Aligns all teams on design and manufacturing while driving ongoing improvements throughout development.
Balancing Costs
Without Sacrificing Quality
Caztek’s DFMA strategy is engineered to minimize production costs while maintaining high-quality standards. By streamlining manufacturing and assembly processes, we reduce material waste, optimize tooling, and ensure efficient assembly. This results in fewer defects, faster production cycles, and lower long-term operational costs, all while delivering reliable, durable products.
Key Cost-Reduction and Quality Strategies:
-
Flexible Tooling: Designed to adapt and minimize the need for costly post-production changes.
-
Waste Minimization: Eliminating unnecessary materials and steps.
-
Fewer Defects: Reducing part complexity to lower the risk of assembly errors.
-
Standardized Processes: Ensuring consistency across all manufacturing stages for high-quality output.
Case Study
DFMA in Action - Inspire
Many handheld injection-molded medical devices, such as our work for Inspire, are prime examples of our DFMA approach. Working closely with the toolmaker, we addressed common injection molding issues like knit lines and sink marks, optimizing surface finishes, and hiding gating to achieve a seamless, high-quality appearance. This collaborative process improved the product's manufacturability and enhanced its aesthetic appeal.
Key Collaborative Achievements:
-
Knit Line Minimization: We optimized molten material flow to reduce knit lines, which occur when two flow fronts meet during the injection molding process.
-
Eliminating Sink Marks: By refining the tooling design and part geometry, we minimized sink marks in thicker areas of the product, ensuring a smooth and consistent surface.
-
Surface Finish Optimization: Collaborating with the toolmaker allowed us to optimize surface finishes, achieving an aesthetically superior product that was easy to manufacture.
