Secondary Operations & Assembly
Transform your injection molded parts into finished products with our comprehensive secondary operations. From ultrasonic welding and pad printing to complex multi-component assembly, we provide complete turnkey manufacturing solutions under one roof.
Core Secondary Operations
Ultrasonic Welding
High-frequency ultrasonic vibration welding for hermetic seals, fast cycle times, and clean assembly without adhesives or fasteners.
Pad Printing
Multi-color pad printing for logos, text, and graphics on curved or irregular surfaces with excellent adhesion and durability.
Surface Finishing
Painting, coating, chrome plating, and texture application for enhanced aesthetics, durability, and functional properties.
Heat Staking
Thermal assembly method for permanently attaching inserts, components, or substrates using controlled heat and pressure.
Insert Installation
Post-molding insertion of threaded inserts, heat-set inserts, or metal components for strong mechanical connections.
Trimming & Deburring
Precision removal of flash, gates, and excess material using automated trimming equipment and manual finishing.
Surface Treatments & Finishing
Chrome Plating
Vacuum metallization for reflective, metallic finishes on automotive and consumer products.
Painting & Coating
Industrial spray painting with UV-curable or solvent-based coatings for durability and aesthetics.
Texture Application
Chemical etching or laser texturing for anti-slip surfaces, grain patterns, and matte finishes.
Polishing
Mechanical or chemical polishing for transparent parts, optical clarity, and glossy surfaces.
Insert Installation
Professional installation of threaded inserts, metal components, electronics, and other hardware into molded plastic parts. We offer multiple installation methods including heat-set, ultrasonic, press-fit, and adhesive bonding to ensure optimal performance.
