Scaling up manufacturing is no easy task. It’s not just about making a product, you have to think about how you’re going to produce high volumes and keep quality consistent, and smooth workflows.
Production scaling relies on knowing your process parameters and thoughtfully considering choices related to the efficiency of processes, equipment choices, and flexibility of designs, to enable scalable and trustworthy manufacturing.
There are many pitfalls during growth, and even the best ideas fall short when the need for a core engineering element is missed. If you have a good understanding of the main engineering considerations early on, it will provide clarity on how to face different concepts and issues in the future.
Main Engineering Principles for Scalable Manufacturing
Engineering decisions matter when you are scaling up manufacturing processes. Building products easier, using common parts and better ways of progressing in your production process can control your costs and improve innovations in quality.
Design for Manufacturability
Design for manufacturability (DFM) is about making a product less complex. The shapes, dimensions, and materials can be done in a way that best enables formulas to process and/or assembly. Reducing part counts and minimizing complex features can reduce the opportunity for error and speed up production.
Involving your manufacturing perspective in the early design process is important. They will point out features that will be difficult to realize, or slow down assembly. They will be able to offer trade-off alternatives so that more costly changes can be avoided.
Also, see how your designs match to the capabilities of your machines or suppliers. Avoid designs needing special tools (with the exception any tools that are necessary).
Standardization and Modularity
Standardization means creating common parts and processes whenever possible. This is important to help streamline your supplies and minimize costs. You spend less time designing or buying unique items for each product.
Modularity is about breaking products into smaller units or modules. These modules can then be reused in different products. It also allows your team to improve products or add features quickly without starting all over.
Benefits of standardization and modularity:
- Faster assembly: Fewer unique parts mean quicker builds.
- Lower inventory: You keep fewer parts in stock.
- Easy upgrades: Swapping modules lets you improve products without big redesigns.
Process Optimization
Process optimization is to find ways to make the routine tasks flow smoothly from one step of production to the next by workflow organizing work stations, reducing machine down time, and relieving bottlenecks.
You can use charts or software to help you analyze where your processing path is weak. You can spend time eliminating your processes or automating repetitive tasks to reduce time and save money in the long run. Tracking metrics such as cycle time, defects, etc., can be very useful as well.
There can be a cumulative effect of small ongoing improvements. Equipping your team with tools to help them identify problems and take the steps to solve them in the processes keeps efficiency and product quality.
Technology Selection and Integration
If you select technology carefully and integrate it appropriately, the production process should offer cost savings, increased speed, and lower errors. Correctly used technology can also help with marketplace changes and customer requests.
Automation and Robotics
Automation and robotics can help you improve productivity and quality across your production lines. Robots are particularly good at repetitive tasks, such as assembly, welding, and packaging, so your workers can focus on jobs that require creative problem-solving or decision-making.
Automation usually offers these key benefits:
- Higher throughput. Since robots can perform tasks at higher speeds, they allow you to produce more items in a shorter time frame.
- Fewer defects. Because robots always perform tasks the same way, you can count on quality and less waste.
- Lower labor costs. You can have robots perform the “routine” work while your workforce is responsible for complex jobs, or oversee several more lines without adding workers.
When selecting robots, consider the different types of products you manufacture and the flexibility you need. You may require robots that can be reprogrammed or retooled to do different jobs.
Digitalization and Industry 4.0 Solutions
Digitalization can provide you with the tools to connect equipment, track material flows, and capture information at each step of the production process. The data you generate during the production process can be used to identify bottlenecks, predict breakdowns, and optimize maintenance scheduling.
Some of the most common Industry 4.0 devices include:
- Sensors and IoT devices: Monitor machines in real time to spot problems before they cause downtime.
- Manufacturing Execution Systems (MES): Track where every order is, from raw material to shipped product.
- Analytics dashboards: See important trends or stats at a glance so you can act fast if something goes wrong.
Connecting machines to work is a matter of applying common protocols or standards. Good training and strong cybersecurity are investments that can help protect your data and staff.
Equipment Flexibility
Flexible equipment can allow you to produce different products or complete different jobs without the burden of long changeover times or costs. This flexibility becomes a high priority when you need to adjust your production rates in response to market demand or when you need to be able to produce more variety in response to the needs of your customers.
Getting flexible equipment:
- Use modular setups: Some machines are designed using interchangeable scalar units, which provide some reconfigurability.
- Adopt quick change tooling: You can ramp up production for a new job sooner if you are able to change parts in shorter order.
- Expect software-based controls: Updating your production routines may only inspire a software change and not necessitate a hardware replacement.
Flexible production systems (functional systems) can help you get your product to market in a timely fashion. This flexibility should push you to make better use of your investment in your equipment, which can be profiled as some level of competitive advantage when your firm or the market in which you operate needs to change at short notice.
Quality Assurance in Scalable Production
If you want to produce a product at scale and meet or exceed certification and licensing requirements, the key will be how well you monitor, validate and modify the processes that make up the value chain that results in the creation of your product. Structured systems allow you to discover problems early and ensure that output is always consistent.
Real-Time Monitoring and Data Collection
Real-time monitoring allows you to identify possible concerns before they turn into larger issues. You can gather information from automated sensors and connected items about temperature, pressure, measurement, and other essential aspects of the production process.
This information allows you to notice deviations efficiently. For instance, if you see an unexpected increase in temperature in a batch operation, you can stop processing before defects occur.
The data also gives you information for each unit, including unique identification (UID) information. UID labels help track each product through the supply chain and ensure compliance with industry regulations.
When you can, you should create real-time dashboards that allow you to view trends as they occur. This enhances the ability of your team to take action quickly, assess the reoccurring issue, and document your response for discussion in future audits or compliance reviews.
Validation Protocols
Validation protocols are step-by-step protocols that will help you validate the process as intended. You need to define acceptance criteria, which defines quality products and process requirements.
Acceptance criteria may include measurements, tolerances, and test results. Each phase of production (raw material, assembly, and finished product) should be validated and verified.
Testing should occur for both process equipment and the systems or products. As an example of testing, equipment will need regular calibrations, and software programs will need to be validated at set intervals.
Once again, the aspect of compliance is critical. A process for UID labeling will help to ensure the item can be traced and verified as tested. Regulators will check that all the validations are complete and acceptable, in documented sequences.Failure to adhere to protocols may involve legal risks or product recalls.
Continuous Improvement Strategies
Quality work does not simply stop upon achieving a goal. Continuous improvement means constantly evaluating ways to lessen mistakes and have processes work smarter (faster, safer, or cost-effectively).
Structured approaches such as Plan-Do-Check-Act or Six Sigma could be used to assess the data gained from the operations processes. You should include feedback from your operators or maintenance staff, as they often see the smaller items or issues come up before they become larger issues.
Regular review of compliance data, UID labeling records and quality trends may also indicate patterns that need to be addressed. You may update training or amend machines based on this. Ultimately, the goal is to have a stable, reliable production process that meets both quality and compliance requirements, each and every time.
Operational and Supply Chain Considerations
Production efficiency will require planned logistics of how materials move through your factory and where your supplies originate. Clear resource management, logistics, and responsible sourcing are all major factors to plan in scale-up operations.
Scalable Logistics Planning
With increase in production, the transportation of raw material to finished product on time, and consistently, becomes even more critical. You will need to map out how supplies will travel from your suppliers to your site, and how finished goods travel to your consumers.
Utilize positive and timelines, as well as real-time tracking of your supplies to avoid shorting you or causing costly delays. It is also useful to consider all available transportation modes for each route, including, but not limited to, trucks, shippers, or airfreight, and all as an example rate for cost and timing.
Essential logistics components:
- List and verify all transport modalities and routes to suppliers.
- Track all shipments, utilizing digital systems when you can.
- Schedule shipments and deliveries to mitigate bottlenecks.
To keep consistent costs, consider automating aspects of the logistics. As well, hold open options to change routes or suppliers should demand or supply change suddenly.ivery. Stay ready to adjust routes and suppliers if demand or supply changes suddenly.
Resource and Capacity Management
To scale production, you will need to balance your resources with your demand. These resources will include, but not be limited to, raw material, labor, equipment, and space.
You will need to plan for inventory to have enough supplies to supply your demand, without buying excess materials and having cash flow tied up in unsold materials. Use inventory management systems to track stocks and reorder before you completely run out.
You should focus on and monitor the following aspects:
| Resource | What to Watch For |
| Materials | Stock levels, lead times |
| Labor | Hiring, training, overtime needs |
| Equipment | Maintenance, uptime |
| Space | Storage limits, process flow |
Set clear targets for your production team and review performance often. Make sure your supply chain partners can grow with you as your orders increase.
Sustainability and Environmental Impact
Large-scale manufacturing can affect the environment in many ways, including energy Additionally, specific to large scale manufacturing is potential affect upon the environment through energy use, waste, sourcing. Choose suppliers that can commit to responsible sourcing or company practices, and identify ways in your operations to recycle or reuse when able.
You should also monitor your factory’s energy and water consumption and determine if it is wise to transition to energy efficiency machines or alternative energy sources such as renewable power.
Steps to enhance sustainability:
- Audit your supply chain for green practices.
- Limit one-time use packaging and provide recycling options.
- Train employees on how to sort waste and the reasons to.
The nature of the work, materials, parts, and being open, will help enhance the confidence in your company with your customers and keep everyone compliant.
