specializing in the research, development, and manufacturing of automatic equipment for stainless steel cups and kettles.

Tube cutting precisely cuts long stainless-steel tubes into individual blanks according to the preset length of the bottle shell, providing uniform workpieces for subsequent processing.

Using specialized rolling tools, the edge of one end of the bottle body (typically the future bottle mouth) is rolled and finished to meet final design specifications.

Ultra-high-pressure water is used as the forming medium to expand tube blanks into complex profiles—such as bulged, gourd-shaped, or curved forms—according to design requirements.

It involves cutting a long, semi-finished inner-liner tube blank (e.g., after thinning) into two or more shorter liners, significantly improving material utilization and production efficiency.

This process reduces the diameter at one end of the bottle body (typically the bottle mouth) through localized compression, creating a defined stepped or tapered structure.

This step trims off excess material left from previous operations to meet final length and dimensional requirements, resulting in clean edges and a dimensionally accurate bottle body.

Processes such as spinning, rolling, and grinding are applied to form and smooth the shoulder contour of the bottle body, ensuring consistent geometry, tight tolerances, and a proper fit with the cap while improving overall appearance.

The welded base is machined, leveled, and smoothed to achieve the designed profile, dimensional accuracy, and flatness, allowing the bottle to stand stable and meet aesthetic standards.

Precisely matched threads are roll-formed on the bottle mouth/opening and the cap (or cap retainer) to ensure reliable engagement and effective, leak-proof sealing.

This step machines both the bottle mouth and the bottom/base to achieve flat, smooth surfaces perpendicular to the centerline, ensuring proper assembly and sealing performance, as well as stable standing and consistent quality.

Roll-forming is used to create a smooth, ergonomic bevel on the bottle mouth rim, removing sharp edges and improving drinking comfort.
