Triangular Lamp Shade Mold - High-Quality Injection Mold from 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.
-
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.

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 strong dimensional stability for high-precision plastic parts.
-
Why is 718 steel chosen for this lampshade mold?
718 steel is selected for its superior mirror polishing capability, wear resistance, and pre-hardening properties. These characteristics ensure high surface quality of the finished lampshade and long-term dimensional stability of the mold without deformation during heat treatment.
-
How does the cooling system work in this mold?
The mold uses a water-cooling system that efficiently dissipates heat during the injection molding process. This design significantly shortens the molding cycle and improves overall production efficiency.
-
What type of ejection system does the mold use?
The mold employs a combined ejection system consisting of pin ejectors and ejector plates. This combination ensures smooth and reliable demolding of lampshade products without surface damage.
-
What products is this mold best suited for?
This mold is ideally suited for the mass production of automotive lighting fixtures such as triangular headlight covers and high-precision lighting equipment, where surface finish, dimensional accuracy, and long production life are critical requirements.
-
What gate system is used and how many cavities does the mold have?
The mold features a hot runner system combined with a normal side gate for efficient plastic flow and reduced waste. It has 2 cavities — one for the right-side part and one for the left-side part — enabling simultaneous production of both components.
