Benefits of Bottle Cap Printing Machine

1

Energy saving

Less Energy Consumption,Overall energy savings per cap can be as high as 45%.
Because plastic cap compression moulding machine need lower heating temperature,which means less energy consumption in both heating and cooling.

2

High specific density and less shrinkage

Equal molding pressure, lower molding temperature allows the result of a higher density. Furthermore, less heating and cooling temperature gap accomplish less shrinkage of caps.

3

Shorter cycle time

Shorter cycle time (2 seconds) and therefore higher productivity.
Due to lower extrusion temperature, caps are more quickly to be cooled down in cool plus mould.It makes shorter cycle time, thus capacity rises.

4

Easy and flexible maintenance

Independent mould make it easier to change mould, only with hand tools but not crane.

Process of Bottle Cap Printing Machine

1.Screen printing on plastic and metal caps is a technique to transfer a design with highly opaque inks on the surface of the closure using silk screens. The effect is a highly glossy impression that can be felt on touch giving a the beverage cap a stunning look.

2.Offset printing on bottle caps & closures uses 2 rollers to transfer the image on the flat cap. This is a preferred technique , as it is cost effective.

3.Inkjet digital printing is efficient for printing small quantities of plastic caps and metallic caps, generally used in promotional printing.

4.Hot stamping and heat transfer can be done on curved, convex surfaces on different shapes & sizes of In this method of decoration, a hot stamping die is made with the desired design, which is pressed against the closure with the foil sandwiched in between. With heat, pressure and contact time, the foil sticks to the cap surface giving it a luxurious metallic finish. This technology usually uses 1 color of foil at a time.

5.Kiss printing/highlighting is the transfer of colored ink to an embossed bottle cap/closure by a roller.

6.Embossing and debossing can be done on the closure caps during its molding to create nice 3D designs on the surface.

7.Pad printing makes printing of 1-6 colors possible on the caps of different sizes. The image registration is very sharp and precise , print quality is superb and the print lasts longer due to high ink deposition. Even the smallest letters can be printed very sharp. Quick changeover times make it a preferred method of printing on caps and closures.

8.Laser marking is a typical high contrast additive free laser marking application for marking QR codes, logos, specific alphanumeric codes etc on the inside or outside of the plastic closures caps and crowns used in PET bottles, aluminium screw caps of glass bottles, aluminum foil lids on food cartons, sheet steel of screw glasses and also synthetic wine corks. Laser marking ensures anti-counterfeiting and is good when each crown/ cap/ closure has to be marked with different data to produce unique codes and characters for promotions. The marking is very sharp, tamper proof, food safe, and very fast. Usually it is an inline process, where the data is fetched directly using special software . This is also called mark on the fly.
