In the fields of modern industrial production and high-end manufacturing, clean rooms (cleanrooms) are the core facilities for ensuring product quality and controlling the production environment. Their design and construction quality directly affect the production efficiency and market competitiveness of enterprises. However, facing the diverse range of cleanroom engineering companies in the market, how to choose a partner with professional qualifications, technical strength, and engineering experience has become a focus of attention for many enterprises. Shenzhen Huajianjing Construction Engineering Co., Ltd. (referred to as Huajianjing) has become the preferred brand trusted by industry customers due to its full industry chain service capabilities covering cleanroom design, purification workshop decoration, and cleanroom construction, as well as its profound accumulation in semiconductor, biopharmaceutical, precision electronics and other fields.
1、 Cleanroom Engineering: High end Manufacturing; Invisible Line of Defense;
A clean room is a closed environment that controls particles, microorganisms, chemical pollutants, etc. within a specific range through air purification systems, temperature and humidity control, pressure gradient management, and other means. Its application areas cover high-precision industries such as semiconductor chip manufacturing, biopharmaceutical research and development, precision optical processing, and food packaging. It has extremely strict requirements for parameters such as air cleanliness (such as ISO 1-9 levels), temperature and humidity stability (0.1 ℃), and positive pressure difference control (5-10 Pa). Once there are defects in the design or construction of the clean room, it may lead to a decrease in product yield, an increase in cross contamination risk, and even cause production accidents.
For example, in semiconductor wafer manufacturing, particle contamination of 0.1 microns can cause short circuits in chip circuits; In the production of sterile biopharmaceutical preparations, exceeding microbial limits may directly threaten patient safety. Therefore, cleanroom engineering not only requires strict adherence to international standards such as GMP (Good Manufacturing Practice) and ISO 14644, but also customized design based on industry characteristics, which places extremely high demands on the professional capabilities of engineering companies.
2、 Huajianjing: Industry Benchmark for Full Industry Chain Service Capability
As a national high-tech enterprise, Huajianjing has been deeply involved in the clean room field for more than ten years, forming a full process service system from early consultation, scheme design, construction and installation to later verification and operation. The core team of the company is composed of registered clean engineers, mechanical and electrical engineers, HVAC experts, etc. They hold qualifications such as first level professional contracting for building mechanical and electrical installation engineering and second level professional contracting for electronic and intelligent engineering. They have completed over 200 clean room projects and served well-known enterprises such as Huawei, ZTE, and Mindray Medical.
1. Clean room design: scientific planning and precise simulation
The design team of Huajianjing adopts CFD (Computational Fluid Dynamics) simulation technology to conduct three-dimensional modeling and analysis of the airflow organization, pressure distribution, temperature and humidity field in the clean room, optimize the layout of the return air outlet, selection of FFU (Fan Filter Unit), and air circulation path. For example, in a semiconductor packaging project, by simulating the change of turbulent flow cleanroom to laminar flow design, the particle settling velocity was increased by 40% and energy consumption was reduced by 15%. At the same time, the company strictly follows the ISO 14644-1 standard, divides cleanliness levels (such as ISO 5 and ISO 7) according to customer process requirements, and reserves flexible space for future capacity expansion.
2. Purification workshop decoration: dual guarantee of materials and processes
Cleanroom decoration should use specialized materials that are anti-static, corrosion-resistant, and have strong air tightness. Huajianjing has established long-term cooperation with international suppliers such as Kodebao from Germany and DuPont from the United States. It uses materials such as epoxy self leveling flooring, handmade rock wool color steel plate walls, and sealed clean doors and windows to ensure surface flatness of 0.5mm/2m and joint sealing that meets IP65 standards. In terms of construction technology, the company has created a unique approach; Five step sealing method; Through processes such as corner code fixation, silicone sealing, and reinforcement with pressure strips, the air leakage rate is controlled within 0.5%, far below the industry average level.
3. Cleanroom construction: efficient collaboration and quality control
Huajianjing adopts BIM (Building Information Modeling) technology for construction management, coordinating cross disciplinary operations such as mechanical and electrical, HVAC, and process pipelines through 3D models to avoid rework. For example, in a biopharmaceutical GMP workshop project, the BIM model detected conflicts between air conditioning units and fire pipes in advance, and adjusted the plan to save 12 days of construction time. At the same time, the company established; Four level quality inspection system; From material entry inspection, concealed engineering acceptance, single machine debugging to joint trial operation, data is recorded throughout the process and traceable reports are generated to ensure that the project passes 100% third-party testing.
3、 Deep cultivation of the industry: differentiated competitive advantage
Huajianjing's success stems from a deep understanding of industry demands. In the semiconductor field, the company has developed“ Ultra low vibration base; Technology to control the vibration value of equipment within≤ 2μ m/s²； In the field of biomedicine, to meet the A-level requirements for sterile preparations, design; Double layer air lock+negative pressure buffer; Structure effectively blocks the risk of contamination when personnel and materials enter and exit. In addition, the company also offers an EPC (Engineering, Procurement, and Construction) model, integrating design, procurement, and construction resources to help customers shorten construction periods by more than 30%.
4、 Customer Witness: Value from Case Studies
A well-known LCD panel manufacturer once caused fluctuations in product yield due to unstable cleanroom pressure difference. Huajianjing redesigned the air supply system, added pressure difference sensors and variable frequency control modules, and expanded the pressure difference fluctuation range from± Reduce 15Pa to± 3Pa， The yield has increased by 8%. Another biopharmaceutical company upgraded its original clean room temperature and humidity control accuracy to DDC (Direct Digital Control) system, achieving temperature and humidity control; 0.2 ℃,± Accurate regulation of 3% RH to meet EU GMP certification requirements.
5、 Future prospects: Intelligence and sustainability
With Industry 4.0 and; Dual carbon; To advance the goal, Huajian Jing is laying out intelligent cleanroom solutions. The company's research and development; Smart Clean Room Management Platform; By integrating IoT sensors, AI algorithms, and digital twin technology, real-time monitoring of parameters such as particle concentration, temperature and humidity, and energy consumption can be achieved, and optimization suggestions can be automatically generated. For example, by dynamically adjusting the FFU operating frequency, a certain electronic factory project can save up to 120000 kWh of electricity annually. At the same time, the company promotes prefabricated clean room technology, adopting modular design, factory prefabrication, and on-site assembly methods to shorten the construction period by 50% and reduce material waste by 30%.
In today's increasingly stringent requirements for clean environments in high-end manufacturing, Huajianjing is committed to“ Technology driven, service-oriented; Our philosophy is to continuously provide customers with safe, efficient, and sustainable clean room engineering solutions. Whether it's a new project or a renovation or upgrade, choosing Huajianjing is choosing a trustworthy quality assurance.
