After the injection molded plastic is manufactured, further post-processing measures will be taken to improve the appearance, performance and practicality of the injection molded parts.
What are the post-processing methods for plastic parts? The following process types are supported by Universe Plastic Factory for post-processing of injection molded plastics:
Plastic trimming
1. Manual edge trimming
Use a knife, scissors or sandpaper to manually remove excess edge structure or burrs.
2. Mechanical trimming
Use special equipment to remove excess structures or burrs, such as deburring machines, grinders and other mechanical equipment.
Plastic surface processing
1. Grinding and polishing
Use sandpaper, polishing machine and other tools to grind and polish the plastic surface to improve the surface finish and aesthetics.
2. Spraying
Improve appearance and provide protection by spraying or coating.
3. Electroplating
Covering the plastic surface with a metal layer, such as chrome plating, nickel plating, etc.
4. Hot stamping
Use heat and pressure to transfer the metal foil pattern to the plastic surface.
5. Printing
such as screen printing, pad printing, etc., suitable for printing patterns or text on plastic surfaces.
6. Laser engraving
Use laser to engrave patterns or text on plastic surfaces.
Plastic structural processing
1. Ultrasonic welding
Use high-frequency vibration to connect two plastic parts together.
2. Vibration friction welding
Heat is generated through vibration friction to connect plastic parts.
3. Hot plate welding
Use a heating plate to melt plastic parts and then connect them.
4. Watering and bonding
Use special glue to bond two or more plastic parts together.
5. Other connections
Use designed screws, buckles, etc. to assemble different plastic parts and other material parts.
6. Other processing
drilling, tapping, insert installation
Inspection and testing
No matter what kind of plastic post-processing method has been carried out, the quality inspection and functional testing of the injection molded parts need to be carried out again to ensure that they meet the design and use requirements.
Summarize
Through the above post-processing techniques, injection molded plastic parts can reach higher quality standards and meet various usage needs.
