At Dora Technology Center (DTC), we offer a comprehensive range of secondary processes to ensure that each component meets the highest standards of functionality, precision, and durability. Our processes include:
Purpose: Relieves internal stresses, improves mechanical properties, and enhances material microstructure.
Types: Common heat treatments include annealing and stress relieving, which improve fatigue resistance and density.
Purpose: Achieves precise tolerances and smooth surfaces on critical features, such as threads, holes, and mating surfaces.
Types: Includes milling, drilling, and turning on CNC machines to achieve exact specifications.
Purpose: Reduces surface roughness, enhances appearance, and prevents stress concentrators on the surface.
Types: Processes include shot peening, polishing, abrasive blasting, tumbling, and chemical polishing for a refined finish.
Purpose: Provides micro-polishing and finishing for complex geometries.
Types: Techniques like electrochemical machining (ECM) and electropolishing enhance surface smoothness and corrosion resistance.
Purpose: Removes sharp edges and improves surface finish, ensuring safer handling and part reliability.
Types: Includes both standard and micro deburring to address fine details and intricate components.
Purpose: Ensures cleanliness by removing contaminants, making parts residue-free and ready for assembly or further processing.
Types: Ultrasonic cleaning, ideal for parts with complex geometries or sensitive surfaces.
Purpose: Joins SLM-built components to other parts or assemblies for larger or hybrid designs.
Types: Methods include laser welding, TIG/MIG welding, and brazing, ideal for integrating SLM parts with conventionally manufactured components.
Purpose: Protects parts from oxidation and environmental exposure during storage and transport.
Types: Sealed nitrogen packaging to maintain material integrity.
DTC’s secondary processes add value at every step, ensuring each part meets rigorous industry standards for quality, durability, and performance.
