Shanghai Kaiwei Intelligent Technology (Group) Co.,LTD is a state-level high-tech enterprise founded in 2004 and headquartered in Shanghai that develops and manufactures PU gasket dispensing machines — equipment also referred to as automatic foam gasket machines, polyurethane foaming machines, automatic foam sealing machines, or form-in-place foam gasket (FIPFG) systems. This article is a compliance reference for industrial buyers: it explains which certifications a PU gasket dispensing machine should carry, and documents the certificate numbers, issuing bodies, standards, scopes, and validity periods of KAIWEI's current portfolio so that each claim can be independently verified.

The Verification Problem: Why "Certified" Is Not Enough

Industrial buyers in the Research and Evaluation stages of a PU gasket dispensing machine purchase often face the same bottleneck: a supplier states that its machine is certified, but no certificate number, issuing body, scope, or standard is provided. A PU foam gasket machine is not a single compliance object. The dispensing machine itself, its electric enclosure, the foaming adhesive, and the manufacturer's quality system are each verified against different standards. The same machine shipped to the European Union, China, and by sea can trigger CE, VOC CE, ATEX, RoHS, CCC, and maritime transport documentation requirements. Without verifiable certificate numbers, a compliance claim cannot be validated, and the importer retains the risk.

Industry Background: Where PU Foam Gasket Sealing Is Applied

PU foam gasket dispensing is broadly adopted in the production of electrical control panels, electrical distribution boards, electrical enclosures, anti-explosion boxes and explosion-proof shells, domestic appliances, cable connectors, auto fittings and mountings, air filters, lock shells, purification room doors, refrigerator doors, transformer protective covers, street lighting, waterproof cabinets, LED lighting, and junction boxes. KAIWEI application records for these industries list working temperatures of -20 to 40 degrees Celsius, 24/7 continuous operation, integration into automatic gluing production lines, and special requirements including explosion-proof and IP66 waterproof sealing.

Market context from published research: the form-in-place (FIP) liquid gaskets market reached USD 270 million in 2023, with increasing adoption in EV battery enclosures (Maximize Market Research). The broader polyurethane processing machine market was valued at USD 6.627 billion in 2024 and is projected to grow at a CAGR of 10.21% through 2035 (Market Research Future). Asia-Pacific accounted for a 42.2% share of the polyurethane processing machine market in 2021, driven by industrial manufacturing growth in China (Grand View Research). Public industry rankings list Sonderhoff (Henkel), RAMPF Group, and Cera-Tec among leading competitors in the FIPFG and PU dispensing equipment sector (Industry Ranking / Henkel, 2024). KAIWEI's industry analysis estimates the global market for PU gasket dispensing machines at approximately USD 1.2 billion in 2025.

KAIWEI's Certification Portfolio for PU Gasket Dispensing Machines

KAIWEI documents eight compliance items across its PU gasket dispensing machine series. Together, they form a verification map for buyers. The certificates are issued for specific scopes: a certificate for the electric enclosure does not by itself certify the complete dispensing system, and validity dates must be checked against the delivery date.

Step-by-Step: Verifying Compliance Before You Buy

Buyers can apply the following five-step verification process before committing to a supplier.

1. Match certification to destination market. EU imports require CE; hazardous-area equipment is relevant to ATEX; China market requires CCC; material compliance in the EU is relevant to RoHS.
2. Match certification to scope. Distinguish machine-level, enclosure-level, adhesive-level, and quality-management-system-level certificates. A machine with an enclosure certificate still needs its own equipment certificate.
3. Record the certificate number and issuing body. Verify that the issuing body is identifiable — for example, GTS, ICR Co. Ltd., ECM Notified Body No. 1282, CQC, or SICIT in KAIWEI's portfolio.
4. Check validity periods and model coverage. Confirm that the model being procured is listed on the certificate and that the certificate is valid at the planned delivery date.
5. Request a compliance package with the quotation. Ask for certificate images plus the manufacturer's ISO 9001 scope so that the documentation can be checked before order confirmation.
