Rising Resin Costs Are Changing the Economics of Scrap

The Challenge

For years, scrap reduction has been viewed primarily as a quality initiative. Producing parts within spec has always been important, but when raw material costs were relatively stable, a few extra minutes of startup or some material scrap were often accepted as part of doing business.

Resin prices have risen in recent months, which is increasing the cost of every bit of material that enters the production line. This means every pound that becomes scrap has a greater financial impact than it did just a few years ago.

The challenge is that scrap rarely begins with a rejected product. More often, it starts with a process gradually moving away from where it should be. The product begins to use more material than intended, concentricity shifts during startup, diameter variation increases beyond normal, and surface defects appear and persist unnoticed. None of these issues is a major event on its own, but they all consume material, time, and production capacity.

By the time those problems appear during a quality check, the process has already produced additional material. The opportunity wasn’t in finding the problem, it was in finding it sooner.

That’s where continuous measurement changes the conversation

Rather than checking product periodically and hoping nothing has changed between samples, LaserLinc tools continuously monitor product characteristics throughout production, including diameter, wall thickness, concentricity, ovality, and surface quality. Instead of a series of isolated measurements, teams gain a continuous view of what the process is doing as production runs.

The value isn’t in collecting more data - it’s in recognizing when the process begins behaving differently than it did five minutes ago, thirty minutes ago, or at the beginning of the shift.

Using Process Visualization

Within the Total Vu™ HMI platform, measurement data is displayed in real time, making trends, variations, and developing process changes easier to recognize and log. Historical data and SPC tools provide additional context, helping teams determine whether a change is simply normal variation or the beginning of a larger issue that requires attention.

In some applications, the response doesn’t even need to wait for operator intervention. The AutoPilot™ positioning system automatically centers the product, typically in under a minute. Instead of repeatedly adjusting tooling and checking samples, operators can reach stable production faster and with less material consumed during startup.

Defect Detection

FlawSense™ dimensional defect detection technology addresses a different problem. Surface defects don’t become less expensive once production is complete. By continuously inspecting 100% of the product surface in real time, defects can be identified while production is still running rather than after additional material has already been produced.

How It Comes Together

None of this eliminates process variation; manufacturing doesn’t work that way. Processes change, materials vary, and production conditions evolve throughout the day. The goal is not to create a perfect process, but to recognize changes early enough that they don’t become expensive.

That’s what makes rising resin costs such an important shift for manufacturers. The financial impact of a process running slightly off target is larger today than it was a few years ago. A little more startup scrap, a little more variation, or a little more wasted material may not seem significant during a single production run. Across months of production, however, it adds up quickly.

As material costs continue to rise, manufacturing teams are paying closer attention to the gap between making a product and making a quality product more efficiently. The companies that understand their processes best will be in the strongest position to reduce waste, improve consistency, and get more value from every pound of material they purchase.
