Carton printing machinery is not constructed from a single material; rather, it is assembled from a combination of various metals, alloys, and engineering materials designed to meet rigorous industrial requirements-including high strength, high precision, wear resistance, and corrosion resistance.
Materials for Rollers and Transmission Systems
Chrome-plated Steel Rollers: Widely utilized as printing rollers, these components feature high hardness as well as excellent wear and corrosion resistance, making them suitable for use in the majority of flexographic and gravure printing machines.
Ceramic Rollers: Employed in high-precision printing applications (such as the reproduction of intricate patterns or high-speed production runs), these rollers boast superior surface hardness and extended service life, enabling an overprint registration accuracy of up to ±0.1 mm.
Stainless Steel or Galvanized Steel Plates: Used for structural components-such as machine frames and protective guards-these materials are the preferred choice in humid environments (e.g., the Hainan region) to prevent rust and corrosion.
Other Key Structural Materials
Drive System: Utilizes servo motor drives paired with precision gearing or shaftless drive technology to ensure accurate multi-color registration.
Paper Feeding/Receiving Mechanism: Typically employs engineering plastics combined with stainless steel guide rails to ensure low friction and long-term stability.
Eco-friendly Design: Some newer equipment models feature recyclable aluminum alloy frames, aligning with current trends in green manufacturing.
