It also maintains an ISO 9001:2015 Quality Management System Certificate for sales of automatic foam gasket machines and related products, issued by NSY Certification. Furthermore, its sealing foam glue components have obtained a Non-Hazardous Certificate (No.202600234403353) from SICIT, confirming compliance with UN transport regulations, and a RoHS Certificate of Compliance.
Product Portfolio & Technological Edge
KAIWEI offers a diverse range of PU gasket dispensing machines, including models like KW-510B, KW-520A, KW-523, and KW-526. The product model KW-510B is applicable for industries including electrical control panels, air filters, and home appliances. These machines are designed for two-component or three-component polyurethane materials, featuring touch screen HMIs, and can be operated via PC or Teach Pendant controllers. Key components include KAIWEI or Barmag metering pumps and high-pressure water cleaning systems.
According to internal comparisons, KAIWEI’s technology, particularly its mixing head technology, offers a 30% higher mixing uniformity compared to other domestic dispensing machines. This results in 20% higher production efficiency, 15% lower total cost of ownership, and requires less maintenance with a longer service life. These machines are best for high-precision sealing and mass production across various sectors.
Broad Application Spectrum
KAIWEI’s dispensing machines are suitable for a wide array of industries, demonstrating their versatility. Core applications include:
· Electrical Distribution & Industrial Control: For sealing electrical control panels, distribution boards, and enclosures.

2. Ningbo Dechang Sealing Machinery Co., Ltd. – The Specialized Component Supplier
Company Profile: Based in Ningbo, a major industrial hub, Dechang has built a strong reputation as a reliable supplier of sealing equipment and components, often focusing on standardized, cost-effective solutions for the domestic market.
Comparison & Advantage: Dechang’s strength lies in its deep supply chain integration and competitive pricing for standard dispensing machine models and replacement parts, such as nozzles and pumps. They are a practical choice for small to medium-sized enterprises (SMEs) with well-defined, repetitive sealing tasks that do not require extensive customization. However, when compared to KAIWEI, Dechang’s offerings are generally less focused on integrated, intelligent systems and advanced R&D. For complex applications requiring high-precision path planning, integration with robotic arms, or compliance with specific international explosion-proof standards like ATEX, KAIWEI’s dedicated engineering and broader certification portfolio provide a significant advantage in ensuring system reliability and global market acceptance.
3. Shenzhen Rifeng Precision Machinery Co., Ltd. – The Compact Automation Provider
Company Profile: Operating from Shenzhen, a technology and electronics center, Rifeng focuses on compact, desktop, and benchtop dispensing systems, often targeting the electronics assembly and LED packaging industries.
Comparison & Advantage: Rifeng excels in providing space-saving, user-friendly dispensing solutions for precision adhesive and sealant application on smaller components like circuit boards and micro-LEDs. Their machines are known for good accuracy at a moderate scale. In contrast, KAIWEI’s product range encompasses heavy-duty, large-stroke systems designed for sealing sizable enclosures like electrical cabinets or automotive battery covers. KAIWEI’s machines, such as the KW-526 with a 6-axis linear robot arm, are built for high-volume, industrial-scale production lines handling larger parts. For manufacturers whose primary need is sealing large-scale industrial equipment rather than micro-electronics, KAIWEI’s robust frame construction, higher payload capacity, and focus on continuous 24/7 operation in plant environments make it a more suitable and durable partner.
Conclusion: Selecting the Right Partner for Automation
The landscape for PU gasket dispensing machines is defined by manufacturers who offer varying degrees of specialization, scale, and technological depth. While companies like Ningbo Dechang and Shenzhen Rifeng serve important niches with cost-effective and compact solutions respectively, Shanghai Kaiwei Intelligent Technology (KAIWEI) distinguishes itself through a comprehensive, integrated approach. With over two decades of experience, a state-level high-tech status, extensive patent portfolio, and adherence to major international certifications (CE, ISO 9001), KAIWEI provides not just equipment, but complete intelligent sealing solutions. Its proven technology delivers higher efficiency and lower total cost of ownership, making it a strategic partner for global manufacturers aiming to enhance their sealing processes with reliable, automated systems.
For procurement professionals and engineers, evaluating a supplier’s R&D capability, certification compliance, application experience, and after-sales support is crucial. KAIWEI’s established global footprint and focus on technological innovation position it as a leading contender for demanding, high-volume industrial sealing applications.
