Production bottlenecks—points where work slows or stops altogether—can cost companies thousands of dollars in lost productivity, delayed orders, and strained workforce morale. While lean process improvements and workforce training can help, many manufacturers are turning to custom machine design and integrated automation solutions to eliminate bottlenecks at their source.
Keep reading to explore how custom machine design tackles bottlenecks, why off-the-shelf solutions often fall short, and how engineering can transform processes.
What Causes Production Bottlenecks?
A bottleneck is any stage in production that limits the overall capacity of the system. Common causes include:
- Manual steps that can’t keep up with automated processes
- Mismatched cycle times between workstations
- Complex quality checks that slow throughput
- Equipment that isn’t optimized for unique part geometries or workflows
Often, bottlenecks aren’t the result of one glaring problem. Rather, they emerge from a combination of workflow inefficiencies, poorly aligned machinery, and human limitations.
Why Custom Machine Design Works Better Than Off-the-Shelf
Out-of-the-box machinery and automation kits are relatively inexpensive and quick to deploy. But they’re inherently generic—they’re built to serve broad use cases, not the nuanced needs of your specific production line.
Here’s where custom machine design shines:
- Tailored to the actual process: Designers build machines that fit your line like a glove. This minimizes unnecessary movement, handling, and time lost.
- Optimized cycle times: Engineers can align the pace of each workstation so that no single step slows the whole line.
- Smarter automation: Custom controls, sensors, and PLC systems ensure decisions and movements happen when needed with minimal intervention.
- Human-centric design: Intelligent design considers operator comfort and safety—reducing fatigue and errors that can compound production delays.
How Machine Design Engineering Targets Bottlenecks
When manufacturers partner with a custom machine builder, they’re really investing in a deep engineering process. Strong machine design engineering involves:
1. Thorough Workflow Assessment
Engineering teams start by observing the real production environment—not just reviewing blueprints or hearing descriptions. They map out where product waits, where workers pile up tasks, and where machines idle. This on-the-ground study uncovers hidden delays and inefficiencies that might otherwise remain invisible.
2. Root Cause Identification
Not all slowdowns are obvious. Some stem from seemingly minor issues like inconsistent part presentation, variability in component sizes, or outdated tooling. Using engineering analysis, designers trace bottlenecks back to their root and determine whether they result from mechanical, electrical, or workflow mismatches.
3. Iterative Design and Simulation
Rather than building and hoping for the best, engineers model proposed machines using CAD/SolidWorks tools. These simulations can predict cycle times, spatial conflicts, and even operator interactions before a physical prototype is built. This reduces trial-and-error on the shop floor.
4. PLC and Control System Integration
Modern custom machines rely on sophisticated software controls to coordinate motion, sensing, and safety. Programmable Logic Controllers (PLCs) and HMIs allow seamless communication between machines and humans. Proper control design ensures that one slow signal doesn’t hold up an entire system.
5. Rigorous Testing Before Deployment
A robust custom machine builder conducts Factory Acceptance Tests (FAT) and Supplier Acceptance Tests (SAT) to ensure the machine performs as expected. This minimizes surprises on installation day and reduces downtime during commissioning.
Examples of Bottleneck-Eliminating Custom Machines
Every industry faces unique production challenges, but some recurring themes emerge:
- Automated assembly cells that synchronize multiple tasks previously done in sequence
- Vision inspection systems that identify defects at speed without sacrificing throughput
- Servo-driven press machines that replace manual or semi-automated presses with precise, repeatable cycles
- Robotic pick-and-place systems that maintain high throughput with minimal errors
By designing each of these custom systems around your part geometry, cycle timing, and material handling, you eliminate the choke points that often plague mixed-model or high-volume lines.
