sustainability in manufacturing

The majority of businesses aspire to achieve sustainability but often lack clarity on where to begin. Many perceive adopting sustainable practices as a daunting task, believing it necessitates a complete overhaul of their production processes to make a significant impact. However, let me assure you that this is not the case.

So, where should you start your journey towards creating more sustainable product design and manufacturing processes?

To genuinely embrace sustainability, focus on making design decisions at the outset. Designing for repair, reducing material usage, refurbishment, remanufacturing, recovery, reuse, and recycling is crucial. It requires a holistic approach that considers a product’s environmental impact throughout its lifecycle.

Over 80% of a product’s environmental impact stems from design decisions made early on.

Here are three ways design changes can drive sustainability:

Sustainability in Design for Dematerialization

Dematerialization, or material usage reduction, emerges as a crucial strategy for sustainability, aiming to reduce material consumption and weight without sacrificing strength and durability. Leveraging cutting-edge technologies like Generative Design, engineers can optimize designs to use only the necessary amount of material, tailored to specific loads and constraints of each application.

Creo Simulation Live offers a seamless platform for quickly assessing how different materials or reduced material usage affect design performance, enabling adjustments earlier in the design process.

Moreover, with solutions like Creo AMX, designers leverage additive manufacturing capabilities to build structures in the most efficient direction, generating automated supports, and showcasing the potential of lattice structures.

These innovations not only allow for a material reduction but pave the way for lighter, more sustainable products that maintain the required level of performance. As we continue to prioritize dematerialization in manufacturing, we edge closer to a future where sustainability and efficiency are seamlessly integrated into every aspect of product development.

Sustainability in Design for Waste Reduction

Designing for manufacturability and minimizing material waste, such as through minimal stock allowance, ensures efficient use of resources from the outset. By leveraging die casting for near-net shape production throughout the manufacturing process, material waste is significantly reduced to maximize material utilization and minimize scrap generation.

Additionally, utilizing numerically controlled (NC) strategies optimized for fast machining and lower energy consumption, such as high-speed machining (HSM) roughing and finishing, contributes to waste reduction and energy efficiency.

Moreover, designing for ease of service and assembly extends product lifespan and reduces the demand for new products. While some parts of a product may wear faster than others, creating products for easy disassembly eliminates waste because you do not have to throw away the entire product to extend the lifespan.

Accurate documentation of assembly and disassembly instructions empowers users to maintain and repair products, minimizing waste and promoting a more sustainable approach to product lifecycle management.

Sustainability in Design for Energy Efficiency

Engineers globally actively address questions such as, “Can we reduce noise and unneeded energy consumption in design?” and “Can we make our design more thermally efficient?” to pave the way for eco-friendly innovation.

Their goal is to pinpoint areas where energy is wasted, but don’t have the most efficient tools to accomplish that task. Modal analysis and thermal analysis enable more streamlined and environmentally conscious designs. Additionally, tools like Creo Flow Analysis optimizes flow efficiency to ensure that products operate with maximum efficiency, minimizing energy requirements without sacrificing performance.

Furthermore, selecting materials that demand less energy to manufacture and recycle adds another layer of sustainability to the design process and reduces the overall environmental impact from production to end-of-life disposal. Through these proactive measures, energy-efficient product design becomes a tangible pathway towards a more sustainable future.

Attention engineers! There’s an easier way to conduct Tolerance Analysis for your CAD designs.

Transforming CAD designs into real and tangible parts is not only rewarding on a personal level but also professionally fulfilling. It combines creativity, problem-solving, and hands-on experience, all culminating in the sense of accomplishment that comes from creating something real from an abstract concept.

 

However, as you already know, physical parts deviate from the idealized representation (the design model) due to many different challenges and manufacturing constraints. Tolerance analysis involves assessing the impact of variations in dimensions, geometries, and other parameters on the final product’s performance and functionality. By utilizing Tolerance Analysis, designers ensure proper fit and alignment of the product components.

 

Improve Quality & Design Innovation

If the goal is to improve quality and design innovation, enable your engineers to perform comprehensive tolerance stack-up analysis. Traditionally this process is a massive pain i.e. repetitive trial-and-error tasks and tedious testing. This part of the design process can be frustrating and often slows down design teams. However, it doesn’t have to be this way!

 

The PTC Creo EZ Tolerance Analysis Extension is a dynamic computer-aided engineering (CAE) tool powered by leading Sigmetrix technology. This extension helps designers by creating a faster, more intuitive workflow to assess the impact of dimensional specifications on your product designs before prototypes or production.
