Essential Welding Machine Operations and Quality Inspections

In the actual operation of welding machines, although different welding machines may have slight variations, the basic principles are the same. Therefore, it is crucial to adjust each part of the welding machine according to the welding machine manual, with special attention to the following key points: (1) Sheet Metal Specifications and Dimensions, Right Angles, […]

Drying Oven Systems in Tinplate Printing: Structure, Functionality, and Optimization

Tinplate printing commonly adopts a continuous heating and drying method, with printing drying ovens typically spanning 24 to 27 meters, and coating solvent content being higher, the drying ovens are generally around 30 meters. These ovens consist mainly of the furnace body, transmission mechanism, heating device, and a heat circulation system. Furnace Body The furnace […]

Overview of Coating Equipment and Adjustment in Offset Printing

Tinplate coating equipment is mainly used for internal and external coating and, at times, can be directly attached behind a printing machine for immediate curing. Main Structure of Coating Equipment Adjustment of coating machine 1. Conveying Section: Refer to the adjustment of the printing machine conveying section. 2. Setting Rubber Roller and Coating Roller (Using […]

Overview of Coating Types in Tinplate Production: Functions and Characteristics

Tinplate coatings are broadly classified into internal coatings, external primers (base oil coatings), undercoats (white rubber coatings), and topcoats. Internal Coating: (1) Primary Purpose: Prevents the corrosion of the can wall and contamination of the contents, ensuring prolonged storage. (2) Key Characteristics: Corrosion resistance, excellent adhesion, flexibility, non-toxic, and odorless, meeting food safety standards. Must […]

Global Trends in Tinplate Development: From Production Strategies to Environmental Innovations

(1) In major tinplate-producing nations worldwide, there is a general trend of no longer establishing new tinplate production units, including those for Tin-Free Steel (TFS). However, developing countries, particularly China, are still in the process of constructing new production lines, experiencing rapid growth. TFS products offer lower production costs and contribute to the conservation of […]
