[0002] Injection molds are precision tools used for the mass production of plastic parts. They are typically made of steel and include core components such as cavities, gating systems, cooling systems, and ejection mechanisms. Their working principle involves injecting molten plastic at high temperatures into the mold cavity, allowing it to cool and solidify before demolding to form the final shape. They are widely used in electronics, automotive, and home appliance industries, enabling the efficient manufacture of plastic products with complex shapes and precise dimensions.
[0003] The inner shell of a label printer has a complex structure because it needs to house the label printing components, which makes demolding difficult during the injection molding process.
