Emabond: Vapor-Proof Radon Fan Housings

Delivering Vapor-Proof Seals and Cutting Costs with Emabond Plastic Welding Technology

The Plastic Welding Challenge

A leading manufacturer of radon fan housings needed a more reliable and cost-effective method of product assembly. Their previous approach relied on bolts and custom gaskets to hold housings together. Not only did this add significant cost per unit, but it also introduced points of potential leakage in an application where “vapor-proof” performance is highly sought after. Complicating matters further, the housings had to protect expensive internal components, making reliability and serviceability just as important as cost reduction.

The Radon Fan Housings Required:

Hermetic, vapor-proof seals to meet strict industry requirements.
Strong, durable welds for long-term reliability
Precision bonding across 31–40 inches of weld line in two housing sizes
An assembly method that reduced reliance on costly gaskets and bolts.
The ability to service or reuse expensive internal components.

The Emabond Plastic Joining Solution

Emabond replaced the outdated bolted assembly with a precise, hermetic weld that eliminated the need for gaskets and screws while supporting the serviceability of expensive internal components. Using polycarbonate housings and custom Emabond profiles, the process delivered consistent strength and a reliable vapor-proof seal across weld lines of up to 40 inches. Beyond assembly cost savings, Emabond plastic welding offered a unique advantage of being selectively unwelded in Emabond equipment, allowing the manufacturer to recover and reuse expensive internal components. This not only improved cost-effectiveness but also gave the customer a sustainability advantage over other joining methods.

Tangible Benefits & Lasting Results

Vapor-Proof Certification: Emabond plastic welding enabled the manufacturer to label their product as “vapor-proof,” a critical differentiator in the radon mitigation market.
Cost Reduction: Eliminated custom gaskets and bolts, lowering per-unit assembly costs.
Durability & Reliability: Hermetic seals provided stronger, longer-lasting protection than mechanical fastening methods.
Low Scrap Rate: Consistent, repeatable welding improved production efficiency.
Component Reuse: The ability to unweld housings for the safe recovery of expensive internal components improved lifecycle cost-effectiveness.

Emabond’s Lasting Impact

By moving from gasket-and-bolt assembly to Emabond welding, this radon fan housing manufacturer gained a major competitive edge. They not only cut costs and reduced scrap but also achieved the vapor-proof performance that defines success in their industry. The ability to reliably seal, service, and reuse components has strengthened their reputation for quality while improving their bottom line.
