Production Process Of Tinplate Boxes?

When Communicating With Customers, We Are Often Asked About The Production Process Of Biscuit Jars, The Shape Selection Of Tea Jars, The Role Of The Small Dots On The Lid, And Color Matching. Generally Speaking, The Production Processes Of Different Types Of Tin Boxes (Such As Biscuit Jars, Tea Jars, Etc.) Are Roughly Similar, But Some Specially Designed Tin Boxes (Such As Styles With Handles And Perspective Windows) Will Have Some Additional Process Requirements.

Production Process Of Tin Boxes

The Production Of Tin Boxes Is Mainly Divided Into Two Major Processes: Printing Process And Stamping Process. The Specific Details Are As Follows:

1. Printing Process

The Printing Process Mainly Includes Two Links: Printing And Oiling:

• Printing Method: Common Processes For Tinplate Printing Include Offset Printing, Screen Printing, Laser Printing, Spray Printing And White Printing. Among Them, Offset Printing And Screen Printing Are The Most Commonly Used Methods And Are Suitable For The Production Of Most Tin Boxes. Laser Printing And Spray Printing Are More Used For High-End Tin Boxes To Achieve More Exquisite Visual Effects.

• Oiling Treatment: After Printing, Special Transparent Oils Such As Bright Oil Or Matte Oil Are Usually Applied On Both Sides Of The Tin Box To Protect The Printed Pattern And Enhance Its Wear Resistance And Glossiness. For Food-Grade Tin Boxes, The Inner Surface Will Also Be Coated With Food-Grade Gold Oil To Prevent Direct Contact Between Food And The Tin Box To Ensure Food Safety.

2. Stamping Process

The Stamping Process Uses The Good Ductility Of Tinplate To Process It Into Tin Boxes Of Various Shapes, Such As Heart Shape, Book Shape, Etc. Through Molds. In Addition, 3d Engraving Can Be Performed On The Surface To Enhance The Three-Dimensional And Artistic Sense Of The Appearance Design. The Main Steps Of The Stamping Process Include:

• Cutting: According To The Designed Knife Edge Line, The Tinplate Is Cut Into Parts Such As The Can Cover, Can Body, And Can Bottom. This Step Requires High-Precision Operation To Ensure The Accuracy Of Subsequent Molding.

• Stamping Molding: Use A Special Mold To Stamp The Cut Iron Sheet Into Shape. Even A Simple Iron Can Requires At Least 15 Stamping Processes, Such As Flashing, Molding, Curling, Punching, Etc.

• Assembly: Assemble The Stamped Parts, Such As Riveting Or Welding The Can Body To The Can Bottom And Can Cover To Form A Complete Tin Box.

• Packaging: The Finished Product Is Packaged At The End To Ensure The Safety Of The Product During Transportation And Storage.

Answers To Common Customer Questions

• Tea Can Shape Selection: Cylindrical Tea Cans Are Suitable For Products With Large Capacity And Loose Tea Leaves, Which Are Easy To Store And Take; Rectangular Tea Cans Are More Suitable For Some Flat Or Strip Tea Leaves, And The Appearance Is More Modern.

• Small Dots On The Lid: These Small Dots Are Usually Air Holes Used To Balance The Air Pressure Inside And Outside The Can To Prevent The Can From Deforming Or Being Difficult To Open Due To Changes In Air Pressure.

• Color Selection: The Color Selection Of Biscuit Cans Should Be Determined According To Product Positioning And Target Customer Groups. For Example, Bright Colors Are Suitable For Children's Snacks, While Simple Tones Are More Suitable For High-End Products.

In Short, Whether It Is A Biscuit Can Or A Tea Can, Its Production Process Relies On Precise Printing And Stamping Technology.
