Triangular Lamp Shade Mold - China Suppliers & Factory with 718 Steel Core and Water Cooling System
Product Overview
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.
Product Features
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.
Use Cases
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.

Frequently Asked Questions
-
Q What material is used for the cavity and core of this mold?
Both the cavity and core are made of 718 pre-hardened plastic mold steel, which offers a factory hardness of 28–35 HRC, excellent polishing performance, and outstanding wear resistance.
-
Q Why is 718 steel chosen for high-precision lampshade molds?
718 steel provides superior mirror polishing capability, ensuring the optical quality and surface smoothness required for lampshade products. Its pre-hardening property also prevents deformation during the mold's service life, ensuring dimensional stability.
-
Q How does the cooling system improve production efficiency?
The water-cooling system is strategically designed within the mold to rapidly dissipate heat after each injection cycle. This shortens the overall molding cycle time and significantly increases production output.
-
Q What type of ejection system does this mold use?
The mold uses a combination of pin ejectors and ejector plates. This dual system ensures smooth, stable, and reliable demolding of finished lampshade products without surface damage.
-
Q What is the gate configuration for this mold?
This mold uses a hot runner system combined with a normal side gate. The hot runner system minimizes material waste and maintains consistent melt temperature, while the side gate ensures controlled and even filling of the mold cavity.
-
Q What types of products is this mold best suited for?
This mold is ideal for mass-producing automotive lighting components (such as triangular headlight covers) and high-precision lighting equipment parts that require strict surface finish, dimensional accuracy, and a long production lifespan.
