All the following treatment will be used in prototype service, such as cnc machining, 3d printing, vacuum casting
1. Sandblasting: Dual Assurance for Texture and Protection
Sandblasting is a surface treatment process that uses compressed air to propel abrasive materials (such as quartz sand, aluminum oxide, or silicon carbide) at high speed onto the prototype surface. Through the impact and grinding action of the abrasives, it achieves uniform processing without direct contact. This method effectively treats complex curves or irregular structures, making it a widely used technique in the custom rapid prototyping industry to enhance surface texture and provide basic protection.
2. Spray Painting: Personalized Customization of Color and Texture
Spray painting involves atomizing pre-mixed paint through a spray gun to evenly coat the prototype surface, followed by drying and curing to form a finished layer. As one of the most widely applied surface treatment processes in custom rapid prototyping, spray painting allows flexible adjustment of color, gloss, and coating thickness, meeting diverse industry needs for personalized product aesthetics.
3. Screen Printing: Accurately Reproducing the Details of Logos and Patterns
Screen printing is a process that transfers ink through the mesh of a screen onto the prototype surface to form graphics or text. Its key advantage lies in the precise reproduction of complex patterns, text, and logos, with strong ink adhesion. This method serves as an essential process in custom rapid prototyping for information communication and detailed decoration.
4. Laser Engraving: Non-Contact, High-Precision Micro-Processing
Laser engraving utilizes a high-energy laser beam to burn or etch the surface, creating fine patterns or textures. Characterized by non-contact processing, extreme precision, and high controllability, it is a premium process in the custom rapid prototyping industry for handling intricate graphics and personalized markings.
5. Electroplating: Imparting Metallic Finishes and High-End Performance
Electroplating is a process that uses electrolysis to deposit a layer of metal or alloy (such as chromium, nickel, gold, silver, copper, or zinc) onto the prototype surface. It excels in giving non-metallic prototypes (e.g., plastic or resin) a metallic appearance or enhancing properties like corrosion resistance and conductivity in metal prototypes. This makes electroplating a key process for achieving high-end aesthetics and functional performance in custom rapid prototyping.
6. Powder Coating: A Practical Process for Thick Coatings and Strong Protection
Powder coating involves applying powdered paint to the prototype surface via electrostatic adsorption, followed by high-temperature curing to form a durable layer. Known for its thick coating, strong adhesion, and excellent corrosion resistance, this process is a preferred choice in custom rapid prototyping for applications emphasizing protection and long-term durability.
