LED industry year-end inventory: some are not just routines

In 2016, a lot of things happened in the LED industry: from March to March next year, four rounds of price surges, raw materials, chips, packaging and downstream lighting, all of which were affected; Osram's lighting business was acquired from Mulinsen, and Lumileds was sold to Apollo. Its funds, etc., horizontally and vertically cross-border overseas, LED industry various large and small acquisitions one after another; from Guoxing Optoelectronics Tang Qionglan resigned as deputy general manager, Foshan Lighting Deputy General Manager Mr. Jie Qing resigned, Lei Lining resigned from Hongli Optoelectronics General Manager In October, the chairman and vice chairman of the company will resign, the independent directors and supervisors of Lianjian Optoelectronics will leave, and Shao Jiaping will transfer to Osram from the general manager and technical director of Career China. The changes are similar to the two years of the year. However, we are still willing to talk about it, not blindly pursuing hotspots, not sorrowful and full of sorrows, not telling the old feelings about the past, just want to track the trajectory of this arrow and shuttle, look for the clues and context of LED development, think about the future of lighting Direction of development. The deep integration of the value chain is still the main theme. Forgive the small series of old tune, no new ideas and integration. However, it is undeniable that integration has already become the new normal of lighting enterprise development in the past two years. Integration is supreme, big integration and big win, small integration and small win, unconformity must be lost. At present, it is the era of comprehensive resource integration. Whoever takes the lead, who is the winner, while these sounds are endless, the lighting companies have already acted (see the table below). From the above table, we can easily see that in 2016, LED industry mergers and acquisitions showed several characteristics: 1. Acquisitions changed into luxury purchases; 2. Overseas acquisitions increased, and many were blocked; 3. Cross-border mergers and acquisitions increased, the main areas were sports and education. , VR, drones, medical and health fields, etc.

Injection Machine Screw And Barrel

The Injection Machine Screw and Barrel are essential components of the injection molding machine. The screw, often referred to as the auger, is a rotating element that functions to transport, plasticize, and compress the material (typically plastic) before injecting it into the mold. The barrel, on the other hand, is a static tube that houses the screw and serves as the chamber where the Plastic Material is heated and melted before being propelled forward by the screw.

Advantages:

  1. Precision and Efficiency:

    • The screw's design and rotation speed can be precisely controlled to achieve desired plasticization and mixing of the material. This ensures a consistent and uniform flow of molten plastic into the mold.
    • The barrel's internal surface is usually polished to minimize friction and heat loss, thereby improving thermal efficiency and material flow.

  2. Material Versatility:

    • Injection machine screws and barrels can be tailored to suit a wide range of plastic materials, from thermoplastics to thermosets. The screw geometry and compression ratio can be adjusted to optimize material flow and plasticity.

  3. Durability and Longevity:

    • Materials like 38CrMoALA, commonly used in screw and barrel construction, offer excellent strength and wear resistance. Proper nitriding and tempering processes further enhance their hardness, durability, and corrosion resistance.
    • Surface treatments like chromium-plating and nitriding also increase the lifespan of the screw and barrel by reducing wear and abrasion.

  4. Energy Efficiency:

    • The optimized design of the screw and barrel helps minimize energy consumption and heat loss. This not only reduces production costs but also contributes to a greener and more sustainable manufacturing process.

  5. Maintenance Convenience:

    • The modular design of modern injection machine screws and barrels allows for easy disassembly and reassembly for maintenance or replacement purposes. This reduces downtime and ensures continuous operation of the injection molding machine.
