When you enter Songmile Packaging factory, what you’ll see is not just efficiently running equipment and neatly organized workshops—it’s an entire production system built around high quality. From automated machines that make sure things are precise, to checking quality every step of the way to catch flaws, to having enough production capacity to keep supplies steady—every part works to avoid problems like bad products and leaks. Let’s take you inside the factory to break down the hidden costs of low-quality trigger sprays, and show you why buying high-quality ones is such a smart business move.
1.Automated Production: Automated Production: The “Precision Guard” to Cut Defects from the Start.

In our main production workshop, we have four automated trigger spray production lines for each of our products, with millimeter-level precision – this is our primary way to eliminate defects. The high-precision injection molding machines we use keep the size error of trigger spray casings under 0.01mm. Compare that to old-style manual injection molding, which has a 3% error rate—automation knocks the initial defect rate right down to below 0.3% from the start.
Even more important: the gasket on the trigger sprays are put together by robot arms, and those arms control force so precisely. That totally fixes the problem of uneven force from manual assembly—you know, the thing that makes seals not work right—and that’s how we cut down on leaks.
And the automation here isn’t on its own, either. The workshop’s system watches real-time data from every machine. If an injection molding machine’s temperature changes more than ±2℃, the system shuts down right away and alerts the team. Technical staff can arrive at the site in a short time and solve the problem. so we don’t end up making big batches of bad products.

We make 80,000 trigger sprays a day with these automated lines, and they only make about 240 defective ones each day. A traditional factory they might have up to 10,000 bad ones daily. Just this one difference saves clients tens of thousands of dollars a year on reworking or throwing away bad products.
2.Full-Process Quality Control: The “Multi-Layer Filter” for Stopping Risks

“Not a single unqualified trigger spray leaves the factory”—that’s the rule for our QC team. To make that happen, we’ve built a “multi-layer quality filter” to catch risks from production all the way to delivery.
First layer: Raw material checks
All the plastic pellets and gasket we use for trigger sprays go through lab tests for heat resistance and aging. Për shembull, gasket have to sit at 80℃ for 72 hours straight—no deformation, no failure.
Second layer: In-production spot checks
Pas montimit, we randomly pick 5 trigger sprays out of every 200 for high-pressure leak tests. We put them under 1.2MPa for 30 minutes. If there’s even any liquid leak, we recheck the whole batch. This step keeps the leak rate under 0.1%—way lower than the industry average of 1%.
Third layer: 100% final inspection before shipping
Every single trigger spray gets a flow stability test and visual check before it shipping. Any trigger spray with a flow error over ±5% gets marked as defective, and we also sort out ones with scratches or burrs. Thanks to these three layers, the pass rate for trigger sprays reaching clients is 99.9%—which means way fewer end-user complaints from trigger spray issues.
3.Large-Scale Production Capacity: The “Reliable Backbone” for Steady High-Quality Supplies

When clients choose high-quality trigger sprays, they often worry: “Will the quality good, but supplies be spotty?” Our production setup is built to fix that worry.
Right now, we have multiple dedicated trigger spray lines. For standard models, daily output hits 80,000—with 300 working days a year, that’s 24 million trigger sprays annually. More than enough to handle long-term bulk orders from big clients.
For custom trigger sprays, our flexible production lines can switch parameters fast. From getting a custom order to starting production, we can finish equipment setup in 24 hours—that’s 50% faster than the industry average.
And here’s the key: we never trade quality for capacity. Every line has its own dedicated QC staff. Even during peak seasons, when lines are running at full speed, we never cut back on QC time. The standards stay the same,every trigger spray has to meet our high-quality bar.

When you walk through our factory, the automated machines, Strict quality inspection, and steady production capacity. Put them all into one thing, making sure you get high quality trigger sprays. We all know a tiny trigger spray can mess up your entire production line, hurt your end product reputation, even damage your brand. For this reason, our products are strictly tested to reduce the defective rate to the lowest level and provide high-quality products to customers.Choosing us is not just picking a good trigger spray. It’s choosing to avoid hidden risks, and making a smart business move for long term profits.
