6 FAQs about [Lithium battery injection molding principle]
Why do EV battery systems need injection molding?
Processing EV battery system parts by injection molding also results in predictable shrinkage values during the molding procedure to ensure the right mold dimensions. Amorphous resins have clear advantages in that they experience minimal changes over a wide temperature range, and post-shrinkage is negligible.
What is the production process of lithium battery?
The production process of lithium battery includes: batching, coating, filming (cutting, roll pressing), auxiliary material processing, core processing, spot welding and edge sealing, liquid injection, forming, air extraction, and volumetric inspection. 1.
Why is molten polymer injected into a mold cavity?
When a molten polymer is injected into a mold cavity in injection molding, a skin layer forms on top of the mold surface. The formation of such a layer may induce incomplete cavity filling, i.e., the so-called ‘short shot’. In this sense, solidification of molten polymer in the cavity needs to be minimized to prevent the short shot phenomenon.
What happens when polymer is injected in a mold?
When the polymer is injected in the cavity, the thickness of the cavity is larger than that of the final molded part. After the resin injection, compression is applied to the mold to decrease the cavity thickness. Consequently, the injected polymer melt is squeezed until the mold cavity is fully filled [ 17 ].
How does ICM add compression to the molding process?
ICM adds compression to the molding processes as illustrated in Fig. 1. When the polymer is injected in the cavity, the thickness of the cavity is larger than that of the final molded part. After the resin injection, compression is applied to the mold to decrease the cavity thickness.
What is injection compression molding (ICM)?
Injection compression molding (ICM) can act as a solution to resolve the issues mentioned above [ , , , , ]. ICM adds compression to the molding processes as illustrated in Fig. 1. When the polymer is injected in the cavity, the thickness of the cavity is larger than that of the final molded part.
