Triangular Lamp Shade Mold - High-Quality Injection Mold by China Suppliers and Factory

The core components of this mold (cavity and core) are made of 718 pre-hardened plastic mold steel. This steel typically has a factory hardness between 28–35 HRC, offering excellent polishing performance, wear resistance, and dimensional stability, making it ideal for manufacturing high-precision plastic products with stringent surface finish requirements. The mold base is made of 45# high-quality carbon structural steel, which, after heat treatment, exhibits excellent comprehensive mechanical properties and is commonly used in manufacturing support structures within molds.

• QWhat material is used for the mold cavity and core?

  Both the cavity and core are made from 718 pre-hardened plastic mold steel, which provides a factory hardness of 28–35 HRC, ensuring excellent surface finish, wear resistance, and long-term dimensional stability.

• QWhy is 718 steel preferred for high-precision lampshade molds?

  718 steel offers superior mirror polishing performance, making it ideal for products with strict optical quality and surface smoothness requirements. Its pre-hardened nature also eliminates distortion risks associated with post-machining heat treatment.

• QHow does the cooling system work in this mold?

  This mold uses a water-cooling system, which efficiently dissipates heat during the injection molding process. This shortens cycle times, improves production efficiency, and ensures consistent part quality across large production runs.

• QWhat ejection method is used to remove the lampshade products from the mold?

  The mold uses a combination of pin ejectors and ejector plates to ensure smooth and stable demolding. This dual-method system reduces the risk of part damage or deformation during the ejection process.

• QWhat type of gating system does this mold use?

  This mold features a hot runner system combined with a normal side gate, which helps reduce material waste, maintain melt temperature consistency, and improve the overall quality of the molded parts.

• QIs this mold suitable for mass production of automotive lighting components?

  Yes. This mold is specifically designed for mass production of automotive lighting fixtures such as triangular headlight covers. The 718 steel's excellent properties ensure it meets demanding requirements for surface finish, dimensional accuracy, and high production volume life cycles.
