Standard Requirements for “LED Frame Mold” Processing

As the market evolves and demand increases, product requirements are becoming more stringent. The variety of mold components and manufacturers producing them is also expanding. Whether these mold components meet market needs is a question we must all do. So, what are the standard requirements for “LED Frame mold” processing?

1. Cold and Hot Fatigue Resistance of Components

Some molds operate under repeated heating and cooling conditions during their working process. This causes tensile and compressive stress on the cavity surface, leading to surface cracks and peeling, increasing friction, hindering plastic deformation, and reducing dimensional accuracy, ultimately resulting in mold failure. Cold and hot fatigue is one of the main failure modes of hot work molds, and these precision mold components should have high resistance to cold and hot fatigue.

2. Strength and Toughness of Components

The working conditions of precision mold components are often very harsh, with some components frequently subjected to large impact loads, leading to brittle fractures. To prevent sudden brittle fracture of mold parts during operation, the mold must have high strength and toughness. The toughness of the mold primarily depends on the carbon content, grain size, and structure of the material.

3. High-Temperature Performance of Components

When the working temperature of the mold is high, the hardness and strength decrease, leading to early wear or plastic deformation and failure of the mold. Therefore, the mold material should have high tempering resistance to ensure that the mold maintains high hardness and strength at working temperature.

4. Corrosion Resistance of Components

Some molds, such as plastic molds, are exposed to chlorine, fluorine, and other elements in plastics during operation. When heated, they decompose to release highly corrosive gases like HCI and HF, which corrode the cavity surface of the mold, increasing its surface roughness and accelerating wear and failure.

5. Fatigue Fracture Performance of Components

During the working process of precision mold components, cyclic stress over long periods often leads to fatigue fractures. These fractures can occur as low-energy multiple impact fatigue fractures, tensile fatigue fractures, contact fatigue fractures, and bending fatigue fractures. The fatigue fracture performance of the mold mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.
