• Graphite sheet die-cutting processing

    Has excellent thermal conductivity. Widely used in 3C products such as NB, mobile phones, LED screens, etc; At present, our graphite raw materials have our own research and production subsidiary (Carbon Valley New Materials), which has advantages in both price and performance compared to the industry in terms of raw materials.
    Main features:
    1. Material thickness can be customized to meet the needs of different products.
    2. High temperature resistance, high strength, and stable chemical properties.
    3. Low thermal resistance, light weight, excellent thermal conductivity, and certain electromagnetic shielding effect.
    4. High thermal conductivity (good horizontal heat dissipation effect), easy to operate
    production method:
    1. Non edge wrapping process: The advantage of this process is that it is simple and cost-effective. The disadvantage is that the product is prone to delamination, powder may fall off the punching edge, and it is easy to conduct electricity.
    2. Single edge wrapping process: This process solves the problems of powder falling off and conductivity at the edges of non edge wrapping processes. The process cost ratio is slightly higher than that of non edge wrapping process, and the disadvantage is that the product is prone to delamination.
    3. Double edge wrapping process: Wrap graphite between black film and double-sided tape, which not only maintains the excellent properties of the original graphite sheet, but also prevents graphite delamination and prevents powder and conductivity from easily falling off the edge of graphite punching

  • Foam protective film die-cutting

    It has excellent dustproof, waterproof, shockproof, and flame retardant properties. Widely used in: mobile phones, appliance casings, electronic sealing gaskets, LCD window gaskets, vibration motor buffer ring gaskets, LED peripheral sealing gaskets, (speaker, camera) buffer gaskets. The main applications of PET protective film are to protect the surfaces of metal products, coated metal surfaces, plastic products, automotive products, electronic products, signage products, profiles, and other product surfaces.
    Main features:
    Protect the surface of metal products, coated metal surfaces, and plastic product tables Surface, automotive product surface, electronic product surface, label product surface, profile table Surface and other product surfaces.
    Main features:
    1. Surface hardening (HC) treatment reaches 3.5-4H, scratch resistant and wear-resistant.
    2. The silicone composite layer serves as an adhesive to prevent the formation of bubbles.
    3. The characteristic of silicone is that it can be repeatedly pasted without leaving any traces or corroding the surface.
    4. Used to protect LCD, touch screens, mobile phones, digital cameras, and PDA screens from scratches during use, achieving a screen protection effect.
    5. The composite silicone layer can effectively absorb some direct collisions and protect the display screen from damage.
    6. Ultra high transmittance optical effect with no residual adhesive after removal.

  • Precision engraving of lens covers

    Main applications:
    Protecting the shooting components of mobile phones and laptops.
    Main features:
    Mobile phone lens covers require high penetration of different spectral bands, as well as impact resistance, dust resistance, and protection of the shooting components;
    1.The printing surface is coated with AR (penetration rate of 95% to 98%) and the front is coated with AF (anti fingerprint)
    2.PMMA reinforced glass is used, with high hardness.
    3.Silk screen black, electric gold, and electric silver have good decorative properties.
    Production advantages:
    1.Class 10000 clean room.
    2.Fully automatic scanning alignment CNC milling processing is adopted, with high precision
