The tooling line supplied by Bow Commercial Co., Ltd. includes wear-resistant precision tooling for metal packaging machines: first and second operation seaming rolls, seaming chucks, blanking punches, draw dies, and ceramic welding guide rollers.

Seaming rolls fabricated from vacuum-hardened tool steel or tungsten carbide with TiN finish
Seaming chucks machined with accurate lip profiles matching specific can diameter specifications
Blanking punches and draw dies finished with micro-lapped edges for prolonged production life
Electrode wire guide wheels and wear-resistant ceramic centering rollers for seam welding

Resistance seam welding kinematics and side-stripe curing in Bow Commercial lines

In high-output 3-piece can body production systems by Bow Commercial Co., Ltd., longitudinal seam integrity is maintained through high-frequency resistance welding utilizing copper electrode wire.

The continuous feed of flattened copper wire prevents tin buildup on electrode discs, stabilizing contact electrical resistance across the overlap margin. Microprocessor units regulate weld current parameters synchronously with blank conveyance velocity.

To prevent food discoloration and internal metal interaction, the weld zone is coated with fine polyester powder or liquid lacquer, followed by rapid induction curing in continuous tunnel ovens.

Multi-stage draw-redraw DRD processes and bottom profile formation engineering

Production of 2-piece seamless containers on DRD press lines by Bow Commercial Co., Ltd. relies on progressive shallow drawing followed by redraw operations without intentional wall thinning. A blanking and cupping die blanks disc shapes from tinplate or aluminum stock and forms a shallow cup.

The drawn preform moves into secondary redraw stations where diameter reduces while can height increases. Tungsten carbide draw rings distribute plastic strain evenly across the blank boundary.

Bottom profiling dies impart concentric expansion rings that accommodate hydraulic expansion during thermal retort food processing.

High-speed shell blanking, conversion tab riveting, and sealing compound lining

Fabrication of easy open ends EOE and peel-off membrane rings on Bow Commercial Co., Ltd. equipment demands micron-level tool precision. Multi-station conversion systems score the opening aperture to an exact residual steel thickness and secure the pull tab via solid metal stake riveting.

Residual score depths are maintained within two microns to enable smooth manual opening without premature micro-fractures during transport.

Rotary nozzles inject liquid synthetic rubber compound into the curled end perimeter, followed by multi-zone convection drying ovens that cure the hermetic sealing gasket.

Metrological double seam inspection and non-destructive optical lacquer gauging

Can hermetic seal reliability depends on precision double seam geometry formed by Bow Commercial Co., Ltd. machinery.

Dedicated optical seam projectors and laser scanning profilometers measure destructive cross-sections, verifying seam overlap percentage, body hook length, end hook length, and seam tightness ratios.

Proprietary measurement software compares dimension data with industry tolerances to detect unaligned seaming roll defects. Non-destructive optical interference film gauges measure external enamel and internal barrier lacquer thickness across moving coil strips without scratching surfaces.

Barrier film permeation evaluation using coulometric gas transmission analyzers

For flexible barrier packaging and multilayer polymer films, analytical systems by Bow Commercial Co., Ltd. deliver precision coulometric detection of gas permeation.

Prepared film samples or finished pouches are mounted into dual-chamber test cells featuring digital temperature and relative humidity regulation.

Trace oxygen molecules diffusing through the barrier membrane are swept by high-purity dry nitrogen into an electrochemical sensor, generating electric current proportional to gas volume. This provides repeatable measurement of barrier performance for sensitive food shelf life.

Tooling maintenance protocols for seaming chucks, rolls, and ceramic blank guides

Operational reliability of canning seamers and stamping presses by Bow Commercial Co., Ltd. depends on durable forming tooling. First and second operation seaming rolls are ground from powder metallurgy tool steel or micro-grain tungsten carbide, finished with titanium nitride TiN wear coatings.

Seaming chuck inserts undergo fine cylindrical grinding with mirror edge polishing to fit specific end curl radii. Routine optical profilometer inspection, ultrasonic wash cycles, and radial runout monitoring on spindle bearings eliminate metal slivers and preserve container flange integrity.
