Certainty Manufactured: Safeguarding 6 Million Households

For LONSID, a National High-Tech Enterprise in the water purification and healthy appliance sector, the pursuit of manufacturing precision and stability has defined its development over more than three decades. Founded in 1988, the company began as a "hidden champion," supplying high-precision electronic components behind the scenes for top global brands such as Sony and Samsung, thereby forging precision and reliability into its corporate DNA. Driven by insights into the "Healthy China" trend, LONSID launched its own brand around the year 2000, transitioning from "behind the scenes" to the "forefront" and entering the smart healthy appliance market. Today, LONSID serves over 6 million households worldwide, and its strategy has evolved from "healthy drinking water" to becoming a "comprehensive health ecosystem builder." However, no matter how its strategy expands, the foundation of its brand promise—"Utmost Purity, Perfect Cleanliness, For Our Loved Ones"—remains firmly rooted in an unwavering commitment to product quality and reliability.

Why choosing WINTEC?

"Safety is the essential '1', and all other factors are the '0's that follow," states Xingyu ZHU, General Manager of LONSID, articulating the core philosophy. "The ultimate competition in health products is a contest of 'Certainty'. And this 'Certainty' must be cast starting from the very first plastic component."

It was precisely this pursuit that led LONSID to choose WINTEC as its core injection moulding equipment partner. "We sought not the cheapest, but the most 'certain'," explains Mr. Zhu. "WINTEC benefits from the technical heritage of the ENGEL Group, and the robustness, durability, and process stability demonstrated by its equipment completely align with our product character, which is built on 'reliability'. 

The value of this 'Certainty' translates directly into 'peace of mind' and 'underpinning support'. The long-term stable operation of the equipment secures the baseline for high-quality volume production, freeing the team from a constant 'firefighting' mode and allowing greater focus on product innovation and user service.

Conquering the Filter Housing Challenge: How WINTEC Achieves 'Millimetre Precision, Leakproof Reliability' with Three Precision Tools

Take the filter housing, the core pressure-bearing component of a water purifier, as an example. It must withstand an extreme pressure of 2.3 MPa and 100,000 cycles of water hammer impact, demanding absolute 'leakproof reliability'. Its safety hinges on three points: material homogeneity free of internal flaws, perfect threaded sealing surfaces, and long-term performance stability. 

WINTEC's precision engineering is precisely the key to overcoming these challenges:

1.Precision Injection and Holding Pressure Control: Ensures the melt fills the mould evenly and smoothly, eliminating shrinkage and stress concentration at the source, resulting in material free of internal flaws.

2.Exceptionally Stable Clamping Force: Guarantees the formation of threaded sealing surfaces with precise dimensions and sharp contours. This is critical for leakproof performance.

3.Precise Barrel Temperature Control: Prevents the plastic from overheating or unmelting, ensures process stability during long-term production, preventing batch-to-batch fluctuations in material performance from affecting the long-term reliability of the finished parts, so that the material properties remain consistent.

"Through our rigorous testing, the failure safety margin of the filter bottles produced by WINTEC far exceeds the national standard. This is the very embodiment of manufacturing reliability," concluded Jianyi HUANG, Manufacturing Director at LONSID. 

'Stable, Precise, Lean': Measurable Strategic Advantages, Perceivable Long-Term Value

LONSID has established a 158-item stringent quality inspection regime. "We never let the user be the 'tester'," says Mr. Huang. The effective operation of this system is entirely dependent on extreme stability in upfront manufacturing. "WINTEC safeguards a superior process stability, " Mr. Huang summarises WINTEC's advantages as Stable, Precise, Lean:

Stable: Long-term stability of process parameters is the foundation for zero variation in volume production. "Only when the equipment is stable can the process be stable; only with a stable process is there a foundation for product consistency."

Precise: Exceptional repeatability eliminates assembly and sealing risks at the root, fulfilling the promise of 'millimetre precision'.

Lean: Significantly reduces energy consumption while being 'labour-saving and worry-free', with low failure rates. "True efficiency isn't about how fast you run, but about fewer problems, less variation, and minimal rework."

It is precisely because the production process is completely controllable and predictable that LONSID sets its internal safety standards far above industry norms, confidently.

Co-creating the Future: A Fellow Partner in Digitalisation and Long-termism

Currently, WINTEC equipment forms the core pillar of the injection moulding workshop in LONSID's smart factory. LONSID defines the standard with 158 tests, but it is WINTEC's stable consistency that makes meeting this standard day after day a rational, achievable outcome.

Looking ahead, Mr. Zhu anticipates deeper collaboration: "For LONSID to maintain leadership in the broad health sector, we need a fellow partner like WINTEC—one that can run alongside us and even scout the path ahead—as a long-term partner in building Certainty."

Particularly in smart manufacturing, WINTEC injection moulding machines, serving as 'high-quality data sources' and 'stable execution terminals', provide a reliable foundation for LONSID's digital advancement.

LONSID's philosophy is 'Act without contention, benefit without harm', meaning it does not engage in low-quality competition but delves deeper into higher standards. WINTEC's value lies in 'solidifying these areas that must be stable for us'. This 'Certainty', originating from the manufacturing source, is the solid confidence that enables LONSID to serve tens of millions of households and steadfastly advance towards a broader healthy future.

This is the WINTEC promise: to provide precision, stability, and repeatability, enabling uncompromising brands to build not just products, but unshakable trust.
