Auto parts injection molding processing
With the penetration rate of new energy vehicles breaking through 30% today, a silent manufacturing revolution is unfolding in the depth of the automotive industry chain. Injection molding, once labeled as "traditional manufacturing," is reshaping the landscape of auto parts production at an astonishing rate of innovation. From the integrated die-casting body of Tesla Model Y to the precision plastic packaging of BYD blade batteries, injection molding and injection mold processing have quietly become the core manufacturing technology in the era of intelligent vehicles.
Material revolution: from ordinary plastics to smart composites
In the NIO ES8 smart cockpit, accessible 3D laser-textured panels are redefining automotive interior aesthetics. This composite, manufactured using microfoaming injection molding technology, achieved a texture accuracy of 0.02mm, and behind it was a major breakthrough in materials science:
1. Long glass fiber reinforced plastic: the length of glass fiber is maintained at 10-25mm, so that the impact strength is increased by 300%
2. Carbon fiber composite material: the density is reduced by 40% while the rigidity is increased by 5 times
3. Self-healing polymer material: scratch can be repaired autonomously at 60℃
4. Conductive polymer: direct injection molding of integrated circuits is possible
Basf's newly developed Ultramid® Advanced N material can maintain 0.05% dimensional stability at 170 ° C injection temperature, and completely solve the global problem of precision electronic packaging.

Two, process evolution: digital driven precision manufacturing
Entering the injection molding workshop of Xushui Intelligent Factory of Great Wall Motor, you will see a completely different production picture: 12 2500 ton injection molding machines form an intelligent production line, and 126 process parameters are transmitted in real time through the industrial Internet of things. Key technological breakthroughs here include:
1. Mold flow analysis 4.0 system: reduce the number of mold trials from the traditional 5-8 times to 1-2 times
2. Dynamic variable mold temperature technology: reduce the surface shrinkage rate from 3% to less than 0.5%
3. Gas-assisted molding optimization algorithm: save 15% of material while improving structural strength
4. Online SPC control system: CPK value is stable and maintained above 1.67
The practice data of a global TOP3 automotive electronics supplier showed that after using digital twin technology, the development cycle of new products was shortened from 120 days to 45 days, and the defective rate was reduced from 800PPM to 50PPM.

Future battlefields: miniaturization and functional integration
When the millimeter wave radar unit needs to integrate 32 precision plastic lenses, the traditional injection molding process can no longer meet the demand. Three major technology directions that the industry frontier is breaking through:
Microinjection molding:
1. The molding weight of 0.01g miniature parts
2. Mold cavity pressure exceeded 3000bar
3. Accuracy of ±3μm
Multi-material co-injection molding:
1. Soft and hard glue seamless combination technology
2. Synchronous molding of metal inserts
3. Layered injection molding of conductive/insulating materials
