Automatic PU Dispensing Machine for Custom Lapel Pins

This automatic doming machine, often referred to as a PU Dispensing Machine or an auto glue dispenser, is a specialized piece of equipment engineered for high-precision application of polyurethane (PU) resin. It is the core tool for creating the iconic, glossy dome effect on custom lapel pins, badges, and similar metal accessories. By automating the critical dispensing process, this pu dispenser accurately fills the recessed cavities of metal pins with liquid resin, which then cures into a durable, protective, and visually appealing finish.

Primary Application:
The machine is essential in manufacturing custom lapel pins, challenge coins, keychains, and emblem badges. These products are typically made from metal alloys (such as iron, zinc alloy, or brass), and the Automatic Doming Machine completes them by adding a perfect layer of colored or clear PU resin.

Key Advantages:

• Unmatched Precision & Consistency: As a high-accuracy Auto Glue Dispenser, it guarantees uniform resin filling—eliminating bubbles, voids, or uneven edges—even for the most intricate and delicate pin designs.

• Dramatically Increased Productivity: This PU Dispensing Machine automates the entire dispensing cycle, vastly outperforming manual methods in speed and reliability, making it ideal for both custom batches and mass production.

• Optimal Material Utilization: The precise volumetric control of the PU Dispenser significantly reduces material waste, ensuring cost-effective operation.

• Superior Product Quality: It produces a smooth, scratch-resistant, and waterproof dome that enhances the pin's aesthetics and longevity, which is the hallmark of a professional Automatic Doming Machine.

• Simple and Versatile Operation: User-friendly controls allow quick adjustments for different pin sizes and resin types, solidifying its role as a flexible and indispensable Auto Glue Dispenser in any badge manufacturing workshop.
