High-pressure physical foaming technology is an advanced cable manufacturing process. Its working process is to first inject hot-melt plastic PE into the mold cavity formed by the plastic sheath around the copper wire of the cable, and then use a precise automatic control system to apply The high-pressure compressed nitrogen or carbon dioxide is injected into the molten plastic, which expands the inside of the plastic part and causes a hollow, and the gas is evenly distributed in the plastic product. When the injection process is completed and the cable is cooled, the cable will have excellent signal transmission characteristics.
SHINEEAST, with its superior gas boosting and control technology, provides manual high pressure gas injection stations and fully automatic high pressure gas injection stations necessary for high performance physical foam cable production lines with stable performance.
◎ The system can pressurize nitrogen or carbon dioxide to a maximum of 600bar;
◎ The system has the function of automatically replenishing the pressure, and it can stop automatically when the pressure reaches the set value;
◎ The system uses precision high-pressure stainless steel pressure reducing valve, which has stable high-pressure output pressure and small pressure fluctuation;
◎ The system uses compressed air as power, with safety and explosion-proof functions;
◎ The system's pressure display adopts precise instruments, and the reading is accurate and reliable;
◎ SHINEEAST's excellent gas booster pump can ensure continuous work and long life;
◎ The output pressure of the system can be adjusted according to different products;
◎ All the pipelines of the equipment are sealed in a highly reliable manner to prevent dripping and leakage, and the appearance is neat and beautiful.
