Lighting Technology

Lighting technology application tungsten and molybdenum components

Semiconductor lighting, also known as solid-state lighting, refers to lighting that uses solid-state light-emitting devices as light sources, including light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs). strong characteristics. Since the 1990s, semiconductor lighting technology has continued to break through, and the application field has been expanding. The technology in the field of indication and display is basically mature and widely used; the technology in special fields such as medical treatment and agriculture is in the ascendant. In recent years, the semiconductor lighting industry has developed rapidly, and foreign countries and Taiwan have strong advantages in different fields. With the acceleration of my country's industrial structure adjustment and development mode transformation process, the semiconductor lighting energy-saving industry has ushered in a new development opportunity period as an important measure for energy conservation and emission reduction.

Advantages of LED light source:

- High energy saving: energy saving and no pollution are environmental protection. DC drive, ultra-low power consumption (single tube 0.03-0.06 watts) electro-optical power conversion is close to 100%, the same lighting effect saves more than 80% energy than traditional light sources.

- Long lifespan: The LED light source is called a longevity lamp, which means a lamp that never goes out. Solid cold light source, epoxy resin encapsulation, no loose parts in the lamp body, there are no shortcomings such as easy burning, thermal deposition, light decay, etc. above.

- Multi-changeable: LED light source can use the principle of red, green and basket three primary colors, under the control of computer technology, the three colors can have 256 gray levels and can be mixed arbitrarily, which can produce 256×256×256=16777216 kinds of colors, forming different The combination of light and color is varied to achieve a variety of dynamic changing effects and various images.

- Environmental protection: better environmental protection benefits, no ultraviolet and infrared rays in the spectrum, no heat, no radiation, little glare, and recyclable waste, no pollution, no mercury, cold light source, safe to touch, typical Green lighting source.

Craftsmanship

Raw Material

Starting from raw materials, we select high-quality raw materials, which is very prominent in the stability and consistency of products. Identify different brands of raw materials and mark the batch number. And each batch of raw materials shall be sampled, inspected and archived. Ensure the traceability of each finished product and continuously improve the product quality.

Milling

The control of the milling process of Mengchang Metal products is very accurate, with several large mixers and vibration platforms to ensure that the materials in the pulverizing and mixing process can be fully stirred and evenly distributed, so as to ensure the internal organization consistency of the products.

Suppress

In the process of powder compacting, the powder is pressed by isostatic pressing equipment to make its internal structure uniform and dense. Mengchang has very perfect batch mold, and also has isostatic pressing equipment to meet the production of ultra-large batches of products.

Sinter

In powder metallurgy, after the metal powder is formed by isostatic pressing, it is heated at a temperature lower than the melting point of the main components to make the particles connect, so as to improve the performance of the products, which is called sintering. After the powder is formed, the dense body obtained by sintering is a kind of polycrystalline material. The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure, which is the core process of powder metallurgy.

Forging

The forging process can make the material obtain higher density, better mechanical properties, and play a role in strengthening the surface. Accurate control of the processing rate and forging temperature of tungsten and molybdenum materials is an important factor for the superior performance of Mengchang tungsten and molybdenum materials. A processing method of using a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size.

Rolling

The rolling process makes the metal material produce continuous plastic deformation under the pressure of the rotating roll, and obtain the required section shape and properties. With advanced tungsten and molybdenum cold and hot rolling technology and equipment, from tungsten and molybdenum metal blank to the production of tungsten and molybdenum foil, mengchang guarantees you more advanced production technology and superior metal properties.

Heat-Treat

After the forging and rolling process, the material is subjected to the heat treatment process to completely eliminate the internal structural stress of the material, give play to the material performance, and make the material easier for subsequent machining. Mengchang has dozens of vacuum furnaces and heat treatment hydrogen furnaces to meet the rapid delivery of mass production orders.

Machining

The material of Mengchanghas undergone complete heat treatment, and then processed into various customized sizes by machining equipment such as turning, milling, cutting, grinding, etc., and ensures that the internal organization of tungsten and molybdenum materials is tight, stress-free and hole-free, which can meet the needs of customers.

Quality Assurance

Quality inspection and control will be carried out from raw materialsand for each steps of the production , so as to continuously ensure the quality every product. At the same time, when finished products are delivered from the warehouse, the appearance, size and internal organization of materials are tested one by one. Therefore, the stability and consistency of products are especially prominent.
