2-PIECE CAN
MANUFACTURING

Two-piece can forming using the DWI (drawn and wall ironed) method was invented in the United States in 1958. A DWI can is formed from aluminum or steel, which is drawn into a cup shape at the cupper before being "wall-ironed". This is carried out with a high speed ram and punch that pushes metal cups through a series of forming rings which stretch the side wall material and creates the domed base of the can against shaped tooling at the end of the bodymaker. After trimming to the correct side wall height, cans go through a washer before heading to the coater/printer where the external print designs are added with an overvarnish. The cans then travel though a curing oven mounted on a pin chain before an internal coating is applied for protection of the contents. After baking in another oven to cure the internal coating, the cans go through the necker where the top is narrowed and a flange is added.

DWI cans are mainly used for beer and carbonated soft drinks (CSD) and for some aerosol products. The can bottom is dome-shaped to withstand internal pressure, often with an added reform groove for additional strength. The can forming method uses the advantage of metal ductility to enable the sidewall to be just 0.1 mm thin, with the can weight being much lighter than typical 3-piece cans. DWI beverage cans come in many standard sizes of diameter and sidewall height with a variety of end/lid style options.

Sencon supports the canmaking process with line and machine control sensors, test and ispection equipment for monitoring the process, and a full range of gauges for measuring and quality control.

PRODUCT NEWS

IN SEARCH OF THE 'LOST' DIMENSIONS

Optical scanning with Sencon's Benchmark™ semi-automatic or Master Series™ fully automatic Back End Gauges now allows important 'lost' dimensions on the can to be measured.

REDUCE YOUR CARBON FOOTPRINT WITH REGULAR OVEN LOGGING

Curing ovens and dryers are a major source of energy use in can making plants. Sencon's smart oven logger can help you to keep it under control.

GAUGING MEASUREMENT CONFIDENCE

Sencon have been using GUM, an internationally recognised method for calculating and documenting all the factors which may affect the certainty of results yielded by measurement systems.

WORLDWIDE SERVICE AND SUPPORT YOU CAN TRUST
