en.Wedoany.com Reported - Daxie Petrochemical recently successfully achieved the first industrial production of polypropylene injection molding grade HP500N and fiber grade Y26, with all product indicators meeting design standards and achieving compliance upon initial production. The company also seized the opportune market peak to achieve full production and full sales, yielding significant results in new product development and profitability.
This grade transition broke the industry norm of generating substantial transition materials during trial production of similar units. Prior to the trial, the technical team conducted full-process simulation exercises for core parameters such as temperature, pressure, and melt flow rate during the grade switch, transforming traditional segmented debugging into gradient-based precise temperature and pressure control. During the transition, the team tracked material property changes in real time, completed parameter matching in advance, ultimately reducing transition material generation by 70%, significantly lowering trial production losses and improving the yield of qualified products. Additionally, the production department conducted thorough technical briefings and implemented meticulous operations throughout the process, ensuring stable and controllable production, with product particle size and uniformity indicators exceeding internal control standards.
The successful launch of the new products benefited from the efficient collaboration between Daxie Petrochemical and CNOOC Sales. The two parties closely aligned with downstream market demands for injection molding packaging and textile fibers, optimizing product performance: HP500N offers superior rigidity-toughness balance, suitable for large injection-molded products; Y26 exhibits excellent fiber uniformity, with spinnability meeting the requirements for high-end nonwoven fabric production. In terms of production-sales coordination, the production side prepared equipment conditions and completed process debugging in advance; the sales team continuously tracked market dynamics, accurately anticipated the polypropylene price uptrend in May, secured downstream customers early, and completed all sales at price peaks, maximizing the profitability of the new products.
