On the industrial stage of double belt continuous presses, endless steel belts constantly endure the triple challenge of high pressure, high friction, and high precision. The chrome plating process acts like a tailor-made “performance armor” for this critical component, using advanced surface modification techniques to tackle the many difficulties posed by complex working conditions — becoming the invisible guardian of stable equipment operation.
Four core values: from durability to process Compatibility
Wear Resistance and Extended Lifespan — Built to Withstand Extreme Demands:
The hard chrome layer forms a robust defense line with its exceptionally high hardness. Under continuous pressure reaching tens of megapascals and high-speed cyclic motion, it effectively resists wear caused by friction between the steel belt, mold, and materials. It minimizes surface scratches and fatigue damage, significantly extending the replacement cycle of the belt and ensuring long-lasting durability during high-intensity operations.
Corrosion Protection — Shielding Against Environmental Threats:
When exposed to air, the chrome layer naturally forms a dense Cr₂O₃ passivation film, acting like a protective coat for the steel belt. This ultra-thin film effectively isolates the belt surface from water, oxygen, oil residue, coolant, and other corrosive agents. It prevents rust and degradation of the steel belt, and more importantly, avoids flaking of oxide layers that could contaminate processed materials — helping maintain a clean production environment and consistent product quality.
Demolding Efficiency — Enhancing Process Flow:
The chrome-plated steel belt features a mirror-like smooth surface with extremely low material adhesion. When handling resin-impregnated composites such as carbon paper and other specialty materials, it significantly reduces sticking and demolding resistance. This is especially beneficial for continuous forming processes, preventing interlayer damage caused by poor release — ensuring a smoother, more efficient production flow.
Thermal Stability — Engineered for Heat-Intensive Operations:
During continuous press operation, localized high temperatures can pose performance risks. The chrome-plated layer maintains stable physical and chemical properties at temperatures below 400 °C, allowing it to handle thermal fluctuations caused by friction or external heating. This effectively prevents performance degradation due to thermal expansion or oxidation, ensuring reliable operation under demanding thermal conditions.
This seemingly thin chrome-plated layer, with its unique physical and chemical properties, has become a “core upgrade” for double belt continuous presses facing complex operating conditions. It not only enhances equipment stability and process precision, but also extends component lifespan — significantly reducing long-term operating costs. Truly, it stands as a classic example of industrial surface treatment technology applied in high-end manufacturing.
It is worth mentioning that MINGKE has successfully developed chrome-plated steel belts, and while deeply cultivating technological innovation, it has always kept in mind its corporate social responsibility and is committed to making positive contributions to the upgrading and development of high-end equipment manufacturing industry.
