Manufacturing Improvement Techniques

🔎 𝗟𝗼𝗼𝗸𝗶𝗻𝗴 𝗶𝗻𝘀𝗶𝗱𝗲 𝗮𝗻 𝗮𝗰𝘁𝘂𝗮𝗹 AMD 𝗰𝗵𝗶𝗽! 😲 Here's a bit of a Ryzen processor made on TSMC's 7-nanometer node. You can see the web of interconnects, the metal wires that connect the transistors (that bottom layer) on a chip to harness their computing power. The image was taken with a new 𝗽𝘁𝘆𝗰𝗵𝗼𝗴𝗿𝗮𝗽𝗵𝗶𝗰 𝗫-𝗿𝗮𝘆 𝗹𝗮𝗺𝗶𝗻𝗼𝗴𝗿𝗮𝗽𝗵𝘆 (𝗣𝘆𝗫𝗟) technique out of the PSI Paul Scherrer Institut, University of Southern California and ETH Zürich. The technique currently has 4 nanometer resolution and the scientists have a path to get to 1 nm resolution. The cool thing about this technology is its non-destructive imaging power to help find defects in chips. Today’s chips are so complicated that electrical tests alone can no longer pinpoint where a defect is: chipmakers use a mix of optical imaging and other methods to zero in on potential problem areas. They then image such areas with a slow but very high-resolution scanning electron microscope. Finally they might take a slice of a chip for further imaging with a transmission electron microscope (TEM). When they find the flaw, they can then go back and correct their design. But with PyXL, they have another tool to pinpoint defects without destroying the chip. ✨

RECYCLING GAME-CHANGER? CHINA SWITCHES ON FIRST FULLY AUTOMATED TEXTILE WASTE SORTING LINE: China has switched on its first fully automated textile-waste sorting line with Databeyond Technology. Using machine vision and hyperspectral imaging, it sorts post-consumer garments by fibre and blend, achieving over 90% purity for polyester, cotton and nylon and flagging elastane blends. The operator says a 15-tonne eight-hour shift that once needed more than 30 workers now runs with four, slashing labour and operating costs. The line is in operation at Zhangjiagang Shanhesheng Environmental Technology Co. Soon after commissioning, Shanhesheng says it received a 200-tonne order for high-purity post-consumer textiles from a global apparel company. A second phase will extend automated sorting to shredded garments and factory offcuts to feed both chemical and biological recyclers. Automated, blend-aware sorting tackles the sector’s key bottleneck between rising collections and the specification-grade inputs recyclers need. It also aligns with China’s push on textile circularity, which aims to expand recycling capacity, recycle roughly a quarter of textile waste, and produce millions of tonnes of recycled fibre.

CCP, PRP & OPRP….. 1. Critical Control Point (CCP) A Critical Control Point (CCP) is a specific step or stage in the food production process where control must be applied to prevent, eliminate, or reduce a significant food safety hazard to acceptable levels. Failure to control CCPs can directly compromise food safety. Key Points: • Identified through hazard analysis. • Requires frequent monitoring. • Has measurable critical limits (e.g., temperature, pH). • Corrective actions are applied if limits deviate. • Documentation verifies control. Example: Cooking chicken to 75°C to kill bacteria. 2. Prerequisite Program (PRP) Prerequisite Programs (PRPs) are basic environmental and operational conditions necessary to maintain hygienic production environments and ensure food safety. They act as the foundation for food safety management systems like HACCP. PRPs control general hazards that are not specific to a particular product or process. Key Points: • Applied across the facility. • Focus on hygiene, cleaning, pest control, and equipment maintenance. • Regular but less intensive monitoring. • Documentation of activities like cleaning schedules. Example: Scheduled equipment sanitation. 3. Operational Prerequisite Program (OPRP) Definition: Operational Prerequisite Programs (OPRPs) are specific control measures identified through hazard analysis to reduce the likelihood of food safety hazards to acceptable levels. Unlike Critical Control Points (CCPs), OPRPs are managed using action criteria rather than critical limits and require regular monitoring to ensure their effectiveness in maintaining food safety Key Points: • Targets specific hazards not covered by PRPs. • Regular monitoring with measurable criteria. • Corrective actions for deviations. • Documented implementation. Example: Metal detector to remove metal fragments. #foodsafety #ccp #prp #oprp

Manufacturing inefficiency is often rooted in old habits. Many manufacturers still cling to batch production — where identical items are produced in large quantities before moving to the next step. While it seems to balance workloads and minimize changeovers, the reality is different. The hidden costs of batch production: Excess WIP inventory Defects hidden in batches Wasted space Uneven workflow Longer lead times These issues lead to: Overloaded stations while others sit idle Poor responsiveness to customer demand Increased scrap and rework Higher facility and carrying costs The better way? One-Piece Flow. Products move through each process step one at a time, making changeovers quick and quality issues immediately visible. Benefits of One-Piece Flow: Faster customer responsiveness Minimal WIP inventory Immediate defect detection Optimized space and handling Easy production leveling to match takt time Real results: 50%+ labor productivity improvement 80% reduction in lead time Quality approaching Six Sigma levels Save you time Run more Kaizen initiatives Drive more revenue Stay tuned! #ContinuousImprovement #LeanManufacturing #Kaizen #IndustrialEngineering #ManufacturingExcellence #ProcessImprovement #OnePieceFlow #KaizenHQ

After spending three decades in the aerospace industry, I’ve seen firsthand how crucial it is for different sectors to learn from each other. We no longer can afford to stay stuck in our own bubbles. Take the aerospace industry, for example. They’ve been looking at how car manufacturers automate their factories to improve their own processes. And those racing teams? Their ability to prototype quickly and develop at a breakneck pace is something we can all learn from to speed up our product development. It’s all about breaking down those silos and embracing new ideas from wherever we can find them. When I was leading the Scorpion Jet program, our rapid development – less than two years to develop a new aircraft – caught the attention of a company known for razors and electric shavers. They reached out to us, intrigued by our ability to iterate so quickly, telling me "you developed a new jet faster than we can develop new razors..." They wanted to learn how we managed to streamline our processes. It was quite an unexpected and fascinating experience that underscored the value of looking beyond one’s own industry can lead to significant improvements and efficiencies, even in fields as seemingly unrelated as aerospace and consumer electronics. In today’s fast-paced world, it’s more important than ever for industries to break out of their silos and look to other sectors for fresh ideas and processes. This kind of cross-industry learning not only fosters innovation but also helps stay competitive in a rapidly changing market. For instance, the aerospace industry has been taking cues from car manufacturers to improve factory automation. And the automotive companies are adopting aerospace processes for systems engineering. Meanwhile, both sectors are picking up tips from tech giants like Apple and Google to boost their electronics and software development. And at Siemens, we partner with racing teams. Why? Because their knack for rapid prototyping and fast-paced development is something we can all learn from to speed up our product development cycles. This cross-pollination of ideas is crucial as industries evolve and integrate more advanced technologies. By exploring best practices from other industries, companies can find innovative new ways to improve their processes and products. After all, how can someone think outside the box, if they are only looking in the box? If you are interested in learning more, I suggest checking out this article by my colleagues Todd Tuthill and Nand Kochhar where they take a closer look at how cross-industry learning are key to developing advanced air mobility solutions. https://lnkd.in/dK3U6pJf

Overall Equipment Effectiveness (OEE) is a metric used to measure how well manufacturing equipment is performing. It evaluates the effectiveness of equipment based on three key factors: Availability, Performance, and Quality. 1. Availability Availability measures how often the equipment is running compared to how often it is supposed to be running. It reflects the percentage of planned production time during which the equipment was actually available for use. Losses in availability can happen due to: Failure loss: When the equipment breaks down and stops working. Setup and adjustment loss: Time spent setting up or adjusting the equipment before it can start production. Tool change loss: Time taken to change tools or other components required for production. Startup loss: The time spent getting the equipment to full production speed after being started up. 2. Performance Performance measures how quickly the equipment is running compared to its maximum speed. Even if the equipment is available and running, it may not always run at its full potential speed. Performance losses can happen due to: Minor stoppage loss: Small interruptions or pauses, such as material jams or brief maintenance activities. Speed loss: When the equipment runs slower than its optimal speed, reducing the number of units produced per unit of time. 3. Quality Quality measures how many of the products produced meet the required quality standards. The focus is on the proportion of defect-free products compared to total products made. Quality losses occur due to: Defect and rework loss: When products are made that do not meet the quality standards and need to be scrapped or reworked. Once you have calculated Availability, Performance, and Quality, you can combine them to determine the overall effectiveness of the equipment. Formula for OEE: OEE = Availability × Performance × Quality Multiply these percentages together to get the overall effectiveness of the equipment.

That’s where smart material selection becomes critical. Whether it’s a reactor exposed to 820°C, a hydrotreating unit vulnerable to hydrogen embrittlement, or heat exchanger tubes corroded by sulfur-laden feeds, the wrong material means higher downtime, failures, and costly shutdowns. Here’s what refinery engineers consider during selection: ✅ Corrosion resistance (aqueous, chloride, sulfur, hydrogen attack) ✅ Mechanical strength under creep & thermal stress ✅ Metallurgical stability (no phase separation or embrittlement) ✅ Codes & specs (ASME, ASTM, API, BIS, etc.) ➡️ Common choices include: ✅ Carbon Steel: Economical, used up to 427°C ✅ Low Alloy Steels (2.25Cr–1Mo, etc.): Ideal for high pressure & temp reactors ✅ Stainless Steels (304, 316, 410, etc.): Excellent corrosion resistance, cladding, trays ✅ Duplex & Special Alloys (Monel, Inconel, Hastelloy): For extreme chemical exposure ➡️ Examples by unit: CDU: Carbon steel + Cr-Mo steels for heater tubes and transfer lines VDU: 9Cr–1Mo or SS 316L for heater tubes FCCU: 2.25Cr–1Mo reactors lined with refractories HGU Reformers: HP-Mod (25Cr–35NiCb) for >900°C ➡️ Codes & specs in play ASTM A335 (P5, P9, P22) for high-temp piping, API 941 Nelson curves for HTHA, and ASME VIII Div.1 for pressure vessels drive the final call.

Understanding PID Tuning in Distributed Control Systems (DCS) In process automation, PID controllers are at the heart of maintaining stable and efficient operations. Tuning the Proportional (P), Integral (I), and Derivative (D) parameters ensures that process variables respond effectively to changes, disturbances, or setpoint adjustments. Why PID Tuning Matters in a DCS: A DCS offers centralized control over multiple process loops across a plant. Poorly tuned loops can cause oscillations, slow response, or instability, impacting quality, safety, and energy efficiency. 1. Proportional (P): This term reacts to the current error (difference between setpoint and process variable). Higher P gain increases responsiveness but too much can cause oscillations. 2. Integral (I): This addresses accumulated past errors. It eliminates steady-state error, but excessive I gain can lead to slow responses and instability due to overshooting. 3. Derivative (D): This predicts future error by observing the rate of change. It adds stability and dampens the response, especially useful in fast-changing processes. However, it's sensitive to noise and is used cautiously. Tuning Methods in DCS: Manual tuning (trial and error): Simple but time-consuming. Ziegler–Nichols or Cohen–Coon methods: Provide a systematic approach. Auto-tuning or adaptive tuning tools: Many modern DCS platforms offer built-in features to help automate this process for faster, more accurate results. Best Practices: Always start with one loop at a time. Ensure the process is stable before tuning. Use trends and historical data from the DCS to monitor performance. Retune after any major process or equipment changes. PID tuning is both a science and an art—and in a DCS environment, it’s crucial for maximizing plant performance. Investing the time to understand and optimize your loops can lead to significant improvements in reliability and productivity. #PIDControl #DistributedControlSystem #ProcessAutomation #IndustrialAutomation #ControlEngineering #AutomationEngineer #PIDTuning #ProcessControl #Instrumentation #ControlSystems #EngineeringInsights #SmartManufacturing #IndustrialEngineering #AutomationCommunity #PlantOptimization
