Why We Chose Metal Tank
Architecture

In portable butane-powered tools, the gas tank is not merely a container
— it is a structural and thermal component of the entire system.

Polymer tanks lower cost but introduce risks: material aging, thermal-cycle fatigue,

and dimensional changes under heat.
A metal tank avoids these weaknesses by delivering stable rigidity and thermal consistency

throughout the product’s life.

Metal construction maintains dimensional stability under internal pressure and prolonged use, offering higher integrity than polymer-based designs.

Higher thermal mass ensures stable heat transfer and reduces thermal fluctuation during extended operation.

Engineered to resist aging, thermal cycling, and demanding environments — prioritizing durability over short-term cost savings.

We selected a full-metal design to ensure structural stability, thermal consistency, and long-term reliability.

This design decision reflects our engineering priority: long-term reliability over short-term cost reduction.
