Jiasheng Service

The company's production site has a rational layout and is fully equipped. The production base covers an area of more than 10,000 square meters, the staff numbers more than 100 people, and the key technical team consists of dozens of experienced process engineers. The company continuously improves its production processes for casting, machining and compaction through its own technology optimization and collaboration with scientific institutions. The annual production capacity of the enterprise consistently reaches 11,000 tons. In accordance with the national policy of green and intelligent manufacturing, the factory has invested more than 50 million yuan in upgrading and renovating production lines, completely replacing outdated high-energy-consuming and low-precision equipment. The international high-tech automatic molding line Disa416, fully automatic molding line Benchuang 418, several energy-saving Rongtai electric furnaces, fully automatic two-position core machines, fully automatic electrostatic spraying line and other advanced equipment were put into operation. Auxiliary equipment includes an intelligent sand preparation system, a centralized PLC control system and a closed-loop dust removal and cleaning system, which provides automated control of all stages of production: from sand dosing, forming, melting and pouring, heat treatment and hardening, precision machining to electrostatic anti-corrosion coating. The introduction of intelligent lines has significantly improved dimensional accuracy, casting density and supply efficiency, while also controlling dust emissions and energy consumption at source, achieving a balance between efficient production and environmental protection. The technological level of the enterprise consistently occupies a leading position in the region.

★ A perfect certification system is a solid basis for product quality and production compliance with requirements. At the product certification level, the company's groove fittings have successfully passed the CCCF fire safety certification, and all products have passed type testing by the National Center for Quality Control of Fire Extinguishing Systems and Fire-Resistant Structures. Key indicators, including pressure resistance, seal reliability, deformation resistance, fire resistance and vibration load, fully comply with the requirements of the state standard GB5135.11, which guarantees the safety of product use. In the field of standardization, the enterprise has successfully passed the certification of ISO9001 quality management systems, ISO14001 environmental management and ISO45001 occupational health and safety systems, and received a third-level production safety enterprise certificate. All products are insured under a liability policy, which provides additional protection for the interests of partners. The company is a member of the Foundry Association of Fangzi District of Weifang City, and actively participates in discussing the development policy of the foundry industry, developing industry standards and exchanging advanced technologies.

★ The company always adheres to the social responsibility of a private enterprise. During severe floods in Henan province, the company promptly responded to the call of the local Komsomol committee and actively collected funds to help the affected areas.
