In the field of model machining and display component manufacturing, acrylic (PMMA) is a preferred material due to its high transparency, excellent machinability, and aesthetic appearance. Within the CNC model manufacturing workflow, acrylic not only allows for precise cutting but can also be dyed to achieve a variety of visual effects. Below is a brief overview of the complete process from CNC milling to dyeing:
1. Material Preparation
High-quality clear acrylic sheets are selected and cut according to design requirements. To ensure optimal machining and dyeing results, the surface must be clean and scratch-free.
2. CNC Milling
The acrylic is precisely machined using a CNC milling machine for shaping, engraving, or drilling. To avoid melting or burr formation, appropriate cutting tools for acrylic should be used, with optimized parameters such as high spindle speed and low feed rate.
3. Surface Finishing (If Required)
After machining, the acrylic surface can be polished to enhance clarity and dye uniformity, especially for visual or display applications. Polishing methods include mechanical polishing or manual finishing.
4. Dyeing Process
Unlike traditional high-temperature dyeing methods, cold dyeing processes are performed at room temperature, effectively preventing material deformation and dimensional deviation, perfectly preserving every detail of your precision machining.
This technique achieves uniform and thorough color penetration with rich, long-lasting hues, and can be applied to high-end custom projects such as optical model, display fixtures, and luxury product showcases.
5. Drying and Quality Check
After dyeing, the acrylic parts are air-dried or gently dried with heat. A final quality check ensures that the color is even and the appearance meets expectations. Additional dyeing or touch-up may be done if necessary.
