Smarter Magnetic Mapping: A Custom Tool That Delivers Repeatability and Flexibility

At Allstar Magnetics, we don’t believe in one-size-fits-all solutions—especially when it comes to magnetic field mapping. A recent project required us to measure the magnetic fields inside long tubes with magnets—a task complicated by the distance normally needed between the probe and the part. Traditional mapping tools would have required a large setup, extra space, and significant cost.   Instead, one of our engineers developed a unique, custom mapping method. By designing a specialized fixture that allowed us to place the probe exactly where needed, we eliminated the distance barrier that usually makes this kind of measurement difficult. The result was a tool that is:
  • Repeatable – Delivers reliable measurements, time after time.
  • Flexible – Can be adapted quickly for different part configurations.
  • Efficient – Saves space and cost compared to traditional mapping systems.
Because this custom solution is both precise and replicable, it streamlines the measuring process not just for this project, but for future projects as well. This innovation is a clear example of how Allstar engineers listen, innovate, and deliver smarter tools that help our customers move faster, with more reliability, and often at a lower cost. When standard tools fall short, the right solution often starts with a technical conversation. If you’re facing a measurement or mapping challenge that doesn’t fit off-the-shelf methods, let’s talk through it together.

Why Engineers Choose Allstar: Designing with Scale in Mind

By Grant Ahn, Director, Engineering and Integration Lead
When I get asked, “Why do companies choose Allstar over anyone else?” my answer is simple: it’s because we think ahead.
 
A lot of development houses are great at designing new products. They’ll create small runs—maybe one to three prototypes—and sometimes they even build them in-house. The problem is, those prototypes are rarely designed with manufacturability in mind. What works in a one-off build often becomes difficult, costly, or even impossible to scale when it’s time for full production.

That’s where Allstar comes in.

Designing with Scale in Mind

When companies pull us into the process early—at the prototype stage—we can help ensure that the design choices being made won’t become roadblocks later. We bring both technical application expertise and real-world manufacturing knowledge to the table. That combination is what sets us apart.

Instead of only thinking about function, we also ask:

  • How easy will this be to manufacture at scale?
  • Will the chosen materials hold up in production without blowing up the budget?
  • Can we simplify the design to improve reliability and reduce cost?

These are questions every engineer needs to consider before moving past the prototype phase.

Partnering Early Pays Off

By working with Allstar at the beginning, your prototype isn’t just proof of concept—it’s a foundation for production. That means when you’re ready to move from small runs to full-scale manufacturing, your design is already optimized to be built efficiently, cost-effectively, and at volume.

Customers choose Allstar for our technical and manufacturing expertise—and stay because we operate like an extension of their development team, anticipating what it takes to turn innovation into reality, seamlessly and without surprises.

If you’re an engineer working on your next big design, don’t wait until the production phase to think about manufacturability. Bring in a partner who can help you scale smart from day one.

Redesigning for Success: How Allstar Helped an AI Robotic Company Solve a Magnet Challenge

Allstar Helped an AI Robotic Company Solve a Magnet ChallengeWhen an AI robotic company came to Allstar Magnetics, they had a clear request: replicate a magnet they already had. But once our engineers reviewed the design, it became clear that the geometry they provided wasn’t manufacturable—and even if it were, it wouldn’t work the way they needed.
 
Instead of simply duplicating a flawed design, our team sat down with the customer to better understand the real requirements. Through this partnership, we uncovered both a sourcing issue and a manufacturing issue that were preventing them from getting the solution they needed.
 
By asking the right questions and leveraging our years of expertise, Allstar was able to:
 

  • Redesign the magnet for true manufacturability
  • Solve an additional performance problem the original design wouldn’t have addressed
  • Deliver samples quickly for fast testing and feedback
  • Provide pricing that was more favorable than their original path

The result was not just a working magnet—but a better solution that met deadlines, reduced costs, and performed reliably.
 
This project illustrates what makes Allstar different: we don’t just build what’s handed to us. We partner with customers, ensuring that what they’re asking for is truly what they need—and often deliver something even better.
 
If your design isn’t working or manufacturability is an issue, Allstar can help you find the right path forward. Let’s talk about how we can turn your challenge into a smarter solution.

What happens when a surgical device fails—and how engineering brings it back to life

A leading medical device company developed a surgical tool designed for use in operating rooms. During real-world procedures, however, the device revealed a critical issue: it would intermittently fail mid-surgery. While surgeons discovered a workaround to re-engage the tool and finish the operation, it was far from ideal.

Determined to resolve the problem, the device’s lead engineer went into the operating room to observe surgeons in action. By studying how and when the failure occurred—and why the workaround was effective—the root cause was identified: the power stage had been mis-designed and required a complete redesign.

What happens when a surgical device fails—and how engineering brings it back to life 

From Prototype to Production: How Allstar Helped

The manufacturer turned to Allstar Magnetics, their magnetic solutions provider. Our team stepped in during the early development phase to help troubleshoot, prototype, and refine the redesign. Beyond solving the technical problem, we collaborated with the client to ensure the solution could be efficiently scaled into production.

By combining engineering expertise with practical manufacturing foresight, Allstar helped move the redesigned device from concept to reality—restoring reliability in the OR and protecting patient outcomes. 

Advice from Our Engineers

Many of our medical device partners bring us in early in the design process, not just after problems arise, to fully benefit from our end-to-end engineering and manufacturing expertise. That’s because Allstar looks ahead—evaluating materials, manufacturability, and cost efficiency while prototypes are still being developed.

The payoff?

  • Time savings by identifying potential design and production challenges upfront.
  • Cost efficiency by aligning prototypes with scalable manufacturing processes.
  • Peace of mind knowing a collaborative partner is invested in both design success and long-term production quality.

As one client told us: “We come to Allstar for the expertise, but we stay for the partnership.”

Smarter Solutions in Action: Custom Tooling for Adhesive Curing

At Allstar Magnetics, we know that every project brings unique challenges. Recently, a customer came to us with a requirement: cure adhesive on specialized magnets and large assemblies at a specific temperature and amount of time. Normally, this would call for a massive industrial oven—an expensive and space-consuming solution.
 
Instead of passing that cost along, our team designed and built a custom oven in-house. By combining electrical and mechanical expertise, we created a flexible system that not only handled this project but can be adapted for future needs. We collaborated with the customer on the initial design of the unit, and now Allstar is refining it further—adding a control box to regulate and modify heat for even more precision.
 
Custom Tooling for Adhesive Curing
 
The result? A solution that was faster, more cost-effective, and tailored to the customer’s needs. Just as important, this innovation adds long-term value: we now have a scalable capability to support similar projects going forward.
 
This project is a great example of how Allstar goes beyond being just a supplier—we’re a partner who listens, innovates, and finds better ways to solve problems.
 
Have a challenging project on your desk? Let’s start a conversation about how Allstar can help you achieve a smarter, more cost-effective solution.
