Epoxy doming machine in Chinese often refers to a dispensing machine, a specialized device used to create raised, transparent, high-gloss 3D effects on the surfaces of flat items such as labels, stickers, and badges. This process involves precisely dispensing liquid resin (such as UV resin or two-component polyurethane) and using curing technology (UV irradiation or chemical reaction) to shape it, thereby enhancing visual appeal, durability, and tactile feel.
Based on the current market situation, dispensing machines are mainly divided into the following categories, suitable for different scales of production needs:
Manual dispensing machines: Operation relies entirely on manual labor, resulting in the lowest cost, simple structure, and ease of carrying and maintenance. Suitable for small-batch production, prototyping, personal hobbies, or small studios. However, its disadvantages include low production efficiency, poor resin consistency, and a high degree of operator skill required.
Semi-automatic dispensing machines: Combining manual workpiece placement with automatic resin dispensing, achieving a balance between cost and performance. Compared to manual models, it offers better consistency, higher production speed, and repeatability, making it an ideal upgrade option for small and medium-sized enterprises or custom sticker shops. However, manual workpiece positioning is still required. Limited scalability.
Fully automatic dispensing machine: Designed for high-volume production, it automates the entire dispensing cycle, including resin metering, dispensing, tray movement, and suction cup retraction, requiring minimal human intervention. These machines offer high production speed, high precision, and excellent consistency, making them the preferred choice for large-scale factory production. However, they have high initial investment costs, require a large floor space, and need trained operators for maintenance.
Digital dispensing machine: Represents the highest level of automation and intelligence, integrating digital programming, data recording, and real-time performance analysis. It supports one-button operation, parameter storage, and precise control, enabling optimal workflow. Process and quality assurance. Suitable for companies with extremely high requirements for production efficiency, accuracy, and data traceability, but expensive and highly dependent on a technical team.
When choosing a dispensing machine, production scale, budget constraints, and quality requirements must be comprehensively considered. Manual models are the entry-level choice, semi-automatic models are suitable for growing businesses, while fully automatic and digital models offer superior efficiency and reliability for large manufacturing enterprises.
Technically, the dispensing machine must be compatible with the resin materials used (such as UV-curing resins or two-component polyurethane), and key specifications such as worktable size, power source, and equipment weight should be considered to ensure smooth integration into existing production processes.
