From Bottleneck to Breakthrough: How One Packaging Manufacturer Cut Cycle Time by 18% with the M8SII Series

 A mid-size packaging manufacturer running high-cavity cap molds had hit a wall. Cycle times had crept up over two years of production, and the aging toggle press behind it could not keep pace with rising order volumes. Something had to change, or the plant would need to add a second shift just to hit the same annual output.

The team switched to Daoben's M8SII Series injection molding machine. Within the first full production run, cycle time dropped by 18 percent, without any changes to the mold or the resin. The full breakdown of specs, settings, and before-and-after production data is available in the M8SII Series molding machine case study.

The Problem: A Machine That Couldn't Keep Up

The plant's original press was rated for the job on paper. But real production told a different story. Injection response lagged behind the process window the mold needed, so operators kept extending hold time just to get consistent parts. That extra hold time added seconds to every single shot, and across three shifts, those seconds turned into real lost output.

Clamp response was also inconsistent shot to shot. So quality checks had to run tighter than they should have, which slowed the line even further.

The Switch: Why the M8SII Series Fit

The M8SII Series was built for exactly this kind of high-repetition, high-cavity production. Faster injection response meant the process no longer needed extended hold time to compensate for a sluggish machine. Clamp force stayed consistent shot after shot, so quality checks could tighten their sampling without slowing the line.

The machine also matched the plant's existing mold without requiring a retrofit. That mattered, because a mold change would have added weeks of downtime and thousands in tooling costs before any cycle time benefit even showed up.

The Result: 18% Faster Cycles, Same Mold, Same Material

With no changes to the mold, resin, or part design, cycle time fell 18 percent. That translated directly into more parts per shift without adding labor or extending hours. Scrap rates also held steady, which confirmed the faster cycle wasn't coming at the cost of part quality.

For a plant running near capacity, that kind of gain is the difference between adding a shift and simply running the equipment already on the floor more efficiently.

What This Means for Other High-Cavity Producers

Cycle time bottlenecks are rarely about the mold alone. Often, the machine underneath it is the real limiting factor, especially on presses that were sized correctly years ago but have since been pushed past their comfortable operating range by rising volume demands.

Daoben builds injection molding machines from 30 to 4,000 tons, so producers facing a similar bottleneck can move up to a faster, more capable platform without starting a mold program from scratch. More on the full manufacturing range is available on the China molding machine manufacturer page.
