China Suppliers Factory for Injection Mold of Triangular Lamp Shade - Durable 718 Steel Design
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.
High-precision forming
◎ 718 steel has excellent mirror polishing performance, which can ensure the smoothness and optical quality of the lampshade surface.
High durability
◎ The pre-hardening properties of 718 steel prevent deformation during heat treatment and improve the long-term stability of the mold.
High-efficiency cooling
◎ The water-cooling system design helps to shorten the injection molding cycle and improve production efficiency.
Reliable demolding
◎ The combination of pin ejectors and ejector plates ensures smooth and stable demolding of lampshade products.
This mold is particularly suitable for the mass production of automotive lighting fixtures (such as triangular headlight covers) or high-precision lighting equipment. The excellent properties of 718 steel enable it to meet the manufacturing requirements of plastic parts with high demands for surface finish, dimensional accuracy, and mass production life.
