What Are the Application Differences of Laser Engraving Technology in Surface Pattern Engraving of Cups? (UV Laser Engraving Machine)

There are stories in cups, and warmth in life. Hello everyone, "Dong Dong's Cup Talk" is here.

With the global market's growing recognition and preference for laser engraving technology on cup surfaces, more and more cup products now feature laser-engraved patterns. However, cups come in a variety of materials—stainless steel, pure titanium, plastic, http://www.zhanyict.com/en/ProductsDetail-VB-10507.htmlglass, ceramics, and more—and the complexity of patterns and engraving difficulty vary significantly. Many industry peers and clients, including ourselves, still lack a thorough understanding of how to select the right laser engraving equipment to achieve optimal results.

Today, based on our factory's extensive experience with various laser engraving machines, we will provide a detailed analysis of the application differences of laser engraving technology in cup surface pattern engraving. http://www.zhanyict.com/en/ProductsDetail-VB-10507.htmlWe’ll also explore the respective advantages and disadvantages of different laser engraving equipment. Given the depth of the topic, we’ll present this information in multiple installments for easier reading.

I. Core Differences and Applicable Scenarios of the Three Major Laser Engraving Machines

2. UV (Ultraviolet) Laser Engraving Machine

Working Principle:

Utilizes a 355nm ultraviolet short-wavelength laser to achieve high-precision, http://www.zhanyict.com/en/ProductsDetail-VB-10507.htmlnon-thermal etching through a "cold processing" mechanism that directly breaks molecular bonds in the material.

Engraving Effects:

- Line precision up to 0.02mm, http://www.zhanyict.com/en/ProductsDetail-VB-10507.htmlideal for micro-text, QR codes, and high-contrast black-and-white patterns.

- No thermal deformation, ensuring clean and precise results.

Suitable Materials:

- Stainless steel plating layers: E.g., vacuum-plated thermos cups—can precisely remove the plating to reveal the metallic finish without damage.

- Glass/Ceramics: http://www.zhanyict.com/en/ProductsDetail-VB-10507.htmlCreates a matte effect through surface micro-explosion, avoiding the cracking risks associated with traditional engraving.

- Certain high-temperature-resistant plastics (e.g., PBT).

Pros and Cons:

- Pros:

- Ultra-high precision.

- Cold processing prevents thermal damage.

- Compatible with multiple composite materials.

- Cons:

- Higher equipment cost (~3x that of CO₂ lasers).

- Low efficiency for deep metal engraving.

Case Study:

A premium thermos cup brand needed to engrave a gold logo on a vacuum-plated surface. http://www.zhanyict.com/en/ProductsDetail-VB-10507.htmlThe UV laser precisely removed the plating layer without damaging the underlying stainless steel, achieving a 99% yield rate.
