In today’s increasingly refined skincare and personal care market, a lotion pump is no longer just a simple dispensing tool. It represents the smoothness and precision of fluid delivery, the comfort of user experience, and, above all, a brand's dedication to quality in every detail.
At Vepo, we understand this deeply. That’s why we adhere to a manufacturing standard that borders on the meticulous: each key component of our lotion pumps is produced with a tolerance of no more than 1 silk (0.01 mm) — equivalent to just one-seventh the diameter of a single strand of hair.
What Does “1 Silk” Mean in Precision?
In precision engineering, “1 silk” refers to an incredibly fine tolerance:
1 silk = 0.01 mm = 10 microns
A human hair is approximately 0.07 mm (70 microns) in diameter.
This means that the dimensional variance in Vepo’s key pump components is no more than 1/7 of a hair’s width.
This extraordinary level of precision enables virtually seamless part assembly, resulting in exceptional sealing performance and fluid dispensing accuracy.
Why Is “1 Silk” So Important?
In a lotion pump, the fit between components — such as the spring, valve, sealing ring, and dip tube — is critical to overall performance. The smaller the tolerance, the more consistent and reliable the pump becomes:
Leak-proof & clog-resistant: Ultra-low tolerance minimizes leaks and prevents backflow issues caused by loose fits.
Smooth & even dispensing: Each press delivers a consistent dose, with no unexpected splashes or gaps.
Superior user experience: Light pressing and gentle rebound create a pleasant, effortless feel.
Extended product lifespan: High-precision parts reduce wear, maintaining consistent performance over time.
