Recently, the technical team led by Liu Yuelin from Zhuozhou Purist Electrical Equipment Co., Ltd. (hereinafter referred to as “Purist”) has successfully tackled a long-standing UV curing incomplete problem that has plagued a major label machine manufacturer in Zhejiang for more than two years. This technological breakthrough not only demonstrates Purist’s profound professional accumulation of nearly two decades in the light source industry, but also wins high customer trust through value-added services beyond product supply, setting a benchmark for technology empowering customers in the industry.
As a senior enterprise with self-owned lamp factories and nearly 20 years of dedicated experience in R&D and production of UV lamps, Purist always adheres to high-quality positioning. Its core UV lamp brand Xupray adopts high-purity GE214A quartz material from the United States and imported halide fillers. Featuring low hydroxyl content and high light transmittance, the lamps ensure stable UV curing performance, and every product is manufactured in strict accordance with stringent production standards. With stable and reliable product performance and a sound market reputation, Xupray UV lamps are sold worldwide, serving as a core partner for many well-known domestic and foreign equipment manufacturers and building extensive industry influence for Purist. The Zhejiang-based label machine manufacturer involved in this cooperation has established a stable partnership with Purist via the Xupray brand since 2022.
However, after completing product upgrading in 2024, the customer frequently encountered the problem of incomplete UV curing, which became a major bottleneck hindering production. In the UV curing industry, such problems are often misjudged as issues with formula or light source quality. The customer initially suspected quality defects in Xupray UV lamps and switched to UV lamp products from multiple suppliers, yet the curing problem persisted. During this period, the two parties held multiple after-sales meetings. Through repeated verification including parameter checking, usage scenario restoration and production condition simulation, the Purist team fully confirmed that Xupray UV lamps completely meet industry standards and customized customer requirements with no quality issues whatsoever. Nevertheless, the unresolved production problem led to a sharp drop in production efficiency, a surge in rework costs, and potential risks to the customer’s market reputation and client trust.
To completely resolve the customer’s difficulties, on the eve of the 2026 New Year’s Day, Liu Yuelin, chief technical engineer of Purist, personally led a team carrying precision testing equipment and company electrical engineers to the customer’s production site in Zhejiang. Boasting 34 years of experience in the light source industry, Chief Engineer Liu Yuelin has in-depth attainments in the field. She has always adhered to the professional philosophy of “combining scientific wavelength matching with chemical kinetics” — a sharp contrast to the extensive solution of “brute-force light irradiation” adopted by some industry peers. This scientific philosophy has long been deeply integrated into Purist’s technology R&D and service system.
During the three-day on-site service, Liu Yuelin’s team devoted themselves entirely to problem diagnosis. Breaking the mindset of attributing faults to single product issues, the team built a full-dimensional inspection system from the perspective of UV curing system coordination. The inspection covered core indicators such as light source output intensity and spectral matching degree, as well as key links including the adaptability of supporting solutions, optical transmission performance, electrical system stability and photochemical reaction efficiency. During the day, the team worked in the roaring production workshop, monitoring real-time production data and conducting repeated tests under various working conditions. At night, they worked overtime until midnight to systematically organize and deeply analyze massive collected data, accurately identify variable factors, optimize and adjust solutions, and resumed on-site verification early the next morning. Their rigorous, efficient and pragmatic professionalism fully reflected Purist’s outstanding technical service literacy and deeply impressed the customer’s team.
After multiple rounds of systematic inspection and precise verification, Liu Yuelin’s team finally pinpointed the core cause of the problem: rather than a single-link failure, it was systemic imbalance caused by multiple overlapping factors. The main issues included unreasonable heat dissipation design of the lamp box, defective light-gathering structure of the lampshade, and poor adaptability between some core internal equipment structures and UV curing processes. These flaws directly led to excessive effective UV energy transmission loss and insufficient spectral matching accuracy, resulting in unsatisfactory curing effects. Targeting these key problems, Liu Yuelin’s team provided the customer with a detailed equipment structure optimization plan. Meanwhile, they adjusted the design parameters of Xupray UV lamps in accordance with the customer’s production rhythm and product characteristics, forming an integrated solution combining “equipment structure optimization and light source adaptation adjustment”. It is worth noting that equipment rectification is a systematic project requiring gradual implementation. The customer will conduct a comprehensive verification of the solution effect after completing all rectification work.
The accurate problem diagnosis and professional customized solution won high recognition and full trust from the customer. The customer spoke highly of the professional technical strength of Purist’s team and even required other cooperative manufacturers to provide technical services in accordance with Purist’s diagnostic standards — yet no other supplier could deliver the same level of professionalism. After returning to the company, Liu Yuelin’s team held another online meeting with the customer to fully summarize the diagnosis process, data support and solutions, supplemented and improved follow-up optimization suggestions, and reached in-depth consensus on the phased rectification schedule and effect verification process. Purist also made a solemn commitment to continuously follow up on the customer’s equipment improvement progress, fully cooperate with subsequent effect verification and parameter fine-tuning, and completely eliminate the curing problem.
“As a team dedicated to light source solution research, we solve light source problems through scientific wavelength matching and chemical kinetics, rather than simple brute-force light irradiation.” This statement from Chief Engineer Liu Yuelin accurately interprets Purist’s core technology philosophy. From a commercial perspective, the customer only purchases Xupray UV lamp products from Purist, and Purist would be fully compliant as long as the products meet quality standards, with no obligation to invest substantial manpower and material resources to solve the customer’s equipment design problems. However, adhering to the corporate tenet of “customer-oriented, value co-creation”, Purist takes the initiative to expand service boundaries relying on Chief Engineer Liu Yuelin’s 34 years of industry experience and the team’s professional technical strength, providing value-added services beyond product supply. This not only helps the customer identify the root cause of the long-standing problem, but also assists the customer in avoiding potential economic losses, upgrading product quality, and improving the core competitiveness of its equipment business after the completion of rectification. It is a vivid practice of Purist, as a technology-oriented enterprise, empowering customers to enhance value through technology.
Purist has long focused on the light source industry, taking high-quality Xupray UV lamps as the foundation, professional technology as the support, and value-added services as the bond to achieve win-win development with global customers. The successful resolution of the customer’s two-year curing problem once again verifies Purist’s solid technical strength in the UV light source field, and highlights its corporate positioning of “not only providing high-quality light source products, but also specializing in professional light source solutions”. In the future, Purist will continue to delve into the light source industry. Leveraging its strong technical team and rich industry experience, the company will provide more customers with high-quality UV light source products and customized professional services under the Xupray brand, empower high-quality development for customers, and continue to write a new chapter of “Technology Empowerment · Value Co-creation” in the industry.
