How do dimensions and structure affect filling performance and durability?

Small tin cans may look simple, yet millimeters decide stability, spray quality, と保存期間. Key structural factors:

コンテナの寸法 直径 + height → stacking strength Volume capacity + fill weight → pressure balance Neck finish → accurate mounting cup crimping
本体構造 Aluminum or tinplate with internal coating resists chemical attack. External lacquer shields against humidity and abrasion. Domed top and concave bottom absorb internal stress during pressure filling or cold filling.
Can body thickness Too thin risks deformation under hydrocarbon or carbon dioxide propellants. Too thick raises cost and reduces line efficiency.

When dimensions align with product concentrate loading and under-the-cup filling, deformation drops and labeling runs smoothly.

What should buyers confirm about valve systems and pressure testing before bulk orders?

A faulty valve turns a stable formula into a warehouse hazard. Careful validation protects both brand and users. Before approval, 確認する:

Valve components alignment: アクチュエータ, 幹, ガスケット, 春, and dip tube seated correctly in the mounting cup.
Compatibility with propellants during IATA 配送.
Verified leakage testing to protect internal coating integrity.
Documented burst pressure results that exceed transport limits.

要するに: 材料 (鋼鉄, アルミニウム, ブリキ), 構造 (welded side seam or seamless), and valve precision must perform as one system. カスタマイズ ensures that when these elements are tested together, small tin cans deliver controlled spray, 安定した圧力, and dependable shelf life.
