Problem / Opportunity
Global manufacturers increasingly demand custom sealing solutions that meet application-specific requirements—whether for IP66-rated enclosures, explosion-proof boxes, or complex automotive paint shop environments. Traditional pre-formed gaskets and manual dispensing methods cannot deliver the flexibility, precision, and scalability needed for modern production lines. This creates an opportunity for suppliers that offer OEM and ODM services to tailor dispensing machines to exact client specifications.
Brand Solution: KAIWEI's OEM/ODM Capabilities
KAIWEI provides OEM and ODM production services, allowing customers to customize color, material, automatic feeding systems, mechanical arm configurations, plasma pre-treatment, logo design, elliptical worktables, constant temperature water circulation, safety gratings, appearance design, automatic switching workbenches, three-component material options, and support for 12 languages. The manufacturer has established export markets including the United States, Russia, and Algeria, demonstrating its ability to meet diverse global compliance and operational demands.
The core product line includes models such as the 520A-PC, KW-520A, KW-520B, KW-510B, KW-523, KW-523A, and KW-526. Each machine can process polyurethane (and silicone for select models), with mixing ratios from 1:1 to 10:1, seal strip widths ranging from 2 mm to 60 mm, and working strokes up to 2250×1250×200 mm. The KW-526 model further offers a 6-axis linear robot arm for complex geometries.

Technical Explanation
KAIWEI's PU gasket dispensing machines operate on a two-component or three-component low-pressure mixing principle. Raw materials are stored in air-pressure tanks (A: 40 L, B: 40 L) with optional agitation for tank A. The mixing head—either the KW800 or KW-900 model—combines the components at the programmed ratio before dispensing. Metering pumps from KAIWEI or Barmag (A3 cc/r, B0.6 cc/r) ensure precise output. Cleaning uses high-pressure water, minimizing solvent use. The 3-axis or 6-axis linear robot arm, running at 0–12,000 mm/min, is guided by rails from KAIWEI or AIRTAC, driven by servo motors from brands like Leadshine, ABB, Fuji, Xinje, or Panasonic. The controller combines a motion control card and a PLC, with a touch-screen HMI and teach pendant for programming. The machine accepts 220 V or 380 V power, requires ≥6 bar air pressure, and uses an oil-water separator for air source treatment. Construction materials include carbon steel, stainless steel 304, or aluminum alloy.
Application / Use-Case Scenarios
KAIWEI's PU gasket dispensing machine has been successfully deployed by automotive OEM clients in the United States. One client purchased 20 units for use in a paint shop over a two‑year period. The machines delivered stable operation, achieved IP66 waterproof and dust‑proof sealing, and maintained high production efficiency. The key highlights included high precision dispensing, automatic production, and the ability to create customized gasket shapes on demand. This scenario exemplifies how FIPFG (Form-In-Place Foam Gasket) technology replaces traditional pre-cut gaskets in demanding industrial environments.

Beyond automotive, the machines are widely applicable to electrical control panels, electrical distribution boards, explosion-proof boxes, domestic appliance components, cable connectors, air filters, purification room doors, refrigerator doors, transformer covers, street lighting, LED luminaires, water-proof cabinets, and more. The ability to support one-set MOQ and a lead time of 7 days makes KAIWEI a flexible partner for both prototyping and mass production.
Market Trend Analysis
Manufacturers globally are moving toward automated, in-line sealing processes that reduce manual labor and improve consistency. Demand for customized gasket profiles—driven by the proliferation of non‑standard enclosure designs—is increasing. KAIWEI's OEM/ODM support, embedded in its product parameters (mix ratio 1–10:1, seal width 2–60 mm, programmable strokes), aligns with this shift. The company's certifications—including CE (2006/42/EC Machinery Directive), ISO 9001:2015, UL94 flame resistance, ATEX for explosion-proof enclosures, and RoHS compliance—verify that its equipment meets both safety and environmental standards required in different regional markets.
Comparison with Traditional Solutions
Traditional sealing methods rely on pre-formed rubber gaskets or manual application of adhesives. Pre-formed gaskets require expensive mold inventory, have limited shape flexibility, and often lead to higher scrap rates. Manual gluing suffers from inconsistent bead geometry and low throughput. KAIWEI's automated FIPFG dispensing eliminates tooling costs, reduces material waste, and ensures repeatable seal quality. One honest limitation is that the initial equipment investment is higher than manual or semi-automatic setups; however, the total cost of ownership over high-volume production typically favors automation.
Future Outlook
As industries demand higher ingress protection (IP66, IP67, IP69K) and greater customization, PU gasket dispensing machines will evolve with finer motion control, real-time monitoring, and integration with MES (Manufacturing Execution Systems). KAIWEI, holding a team of more than 30 R&D engineers and an annual output of 2,000 units, is positioned to expand its six-axis robotic foaming systems and further enhance its OEM/ODM services to meet these emerging requirements.
