Dear Partners, Customers and Friends,

Greetings!

In accordance with China’s Qingming Festival holiday arrangement and the actual operation of the company, Guangzhou SIENOX Technology Co., Ltd. will be closed from April 4 to April 6, 2025 (Friday to Sunday), for a total of 3 working days. We will resume normal work on April 7 (Monday). During the holiday, production, sales and customer service will be adjusted accordingly. Details are as follows:

I. Holiday Production Arrangement

To minimize the impact of the holiday on order delivery, we have made careful arrangements. On April 3, the company will complete quality inspection and outbound delivery of the last batch of equipment before the holiday. For customers with signed contracts, we will communicate in advance to confirm the specific delivery time. Meanwhile, on-site staff will be arranged at the production base during the holiday for routine equipment maintenance and safety inspection to ensure rapid resumption of production after the holiday.

II. After-sales Service Support

We will not neglect customer support even during the holiday. From April 4 to 6, the after-sales hotline 020-87548184 will remain available 24 hours a day. Please feel free to contact your dedicated account manager for emergencies. In addition, our official website will continuously update solutions to frequently asked questions. You may also leave messages online for consultation, and we will reply within 24 hours.

III. Business Consultation Channels

If you have inquiries about equipment procurement or technical parameters during the holiday, please reach us through the following channels:

- Visit SIENOX official website (www.sienox.com) and consult via online customer service.

- Call 18925129293 directly; our professionals will serve you.

Inherit Craftsmanship, Build a Solid Foundation of Quality

Qingming Festival is not only a traditional festival for remembering ancestors, but also an important occasion carrying cultural heritage and craftsman spirit. Since its establishment, SIENOX has taken "Strive for Perfection and Pursue Excellence" as the core corporate value, which coincides with the inheritance spirit embodied by Qingming Festival.

Our planetary mixing and defoaming machines adopt precision manufacturing technology paired with intelligent control systems to realize uniform dispersion and efficient defoaming of materials under vacuum conditions. During product R&D, every component goes through 12 strict inspection procedures, and each equipment undergoes a 72-hour full-load operation test before delivery. These efforts demonstrate our persistent pursuit of quality and our deep appreciation for customer trust.

Grateful for the Journey, Hand in Hand for a Shared Future

Looking back, SIENOX has stood out in the fiercely competitive market thanks to the support and trust of every partner. In the future, we will continue to increase investment in R&D, continuously optimize product performance, and provide smarter and more efficient solutions for new energy, electronics, medical and other industries.

As the Qingming holiday approaches, all staff at SIENOX wish you:

- Respect and filial piety when remembering ancestors.

- Relax and embrace the beauty of nature during spring outings.

Smooth work, happy families and fulfilling life.

Kind Reminder

Order processing and logistics delivery may be concentrated after the holiday. We recommend planning your demands in advance so we can serve you in a timely manner. Please contact your account manager beforehand if you need the green channel for urgent orders.

Thank you again for your understanding and support!
