In 2017, we achieved the best sales performance of Litong in the first half of the year in history: the super Hercules series products have been maintained for a long time, the 7K / 16C products of plastic hoses for crude oil exploration have been certified by API, and the newly developed Teflon with high, medium and low voltage will be the standard plastic hoses. Translated into Chinese as "King House", the name is "the head of plastic hose". Litong phase III project was put into use in 2019. The Xifa composite plastic building of Litong liquid intelligent industrial base has long been completed. The annual production capacity of gk190e is 10000 tons. The automatic intelligent production line of plastic compound was successfully completed and put into operation. Many rubber hoses will have high temperature in the whole process of application. If the plastic particles are placed for a long time, the temperature will rise. Therefore, Litong continued to improve and reduce the mutual matching amount of vulcanization accelerators. Many discussions were also made at the matching level. Various anti coking agents were tried. For most of the plastic particles to be refined, first, the mixed plastic mixture was placed in the hot kneader for pre molding. After it was determined that the plastic mixture was not ignited, the new mixture was added to the mixed rubber. In the 17 year development trend, Xinxiang Litong hydraulic press has continuously made independent innovation, obtained 14 patented inventions, 17 design patents and 9 provincial and ministerial scientific research achievements. China's CNAs verification laboratory selects imported high-grade products to develop weapons and equipment. It is known as a high-tech enterprise in Henan Province and has won many awards. It will completely reach the industries of high-end equipment, crude oil petrochemical industry, steel metallurgy industry, urban rail transit, electric power and energy, chemical plant, pharmaceutical industry and so on. Founded in 2003, the company has developed into a well-known enterprise with an output of 300 million RMB in a short period of more than ten years. It has introduced 10 excellent steel wire winding and packaging machines from Mayer, France, more than 20 excellent steel wire rubber hose weaving machines, Korean winding and packaging machines and other excellent production equipment. At the same time, the company can independently develop and manufacture high-speed weaving machines to ensure the controllability of independent production and manufacturing. Among the international top product categories, professional production equipment and test equipment are introduced to move towards high-grade and make unremitting independent innovation. Litong hydraulic press has always paid attention to fine carving at the level of manufacturing technology, especially the method of calcining waste heat recovery and treatment. Whether it is calcining waste heat recovery heat treatment, or waste heat recovery aging treatment and other casting processes, Litong professional technicians are familiar with the whole process, and the whole process is not easy to solve problems. According to different production processes and product requirements, rigorous production processes are selected in different links to obtain the structure and reflection required by everyone.
