Recently, Shanghai Junyi Filter Equipment Co., Ltd. (Shanghai Junyi Filter Equipment Co., Ltd.) successfully completed the production of the Romanian fastener factory order (contract number: JY20251204GL, order number: 1609#) with its deep adaptability to corrosive conditions and professional customized production capabilities. This customer-customized XAS2/380 type manual oil cylinder filter press was specifically designed for the recovery of the plating solution in the bolt plating process, precisely meeting the filtering requirements for highly corrosive media, with strict material selection, standardized configuration, and efficient production process demonstrating Junyi’s professional level in industrial filter equipment customization and export services.
Condition-based: Precisely solving the problem of filtering corrosive media
The Romanian customer has been deeply engaged in the manufacturing of fasteners, and in their bolt plating process, they need to perform solid-liquid separation on the zinc chloride (ZnCl₂) and ammonium chloride (NH₄Cl) plating solution, recover the useful liquid and remove iron impurities (content 2-3g/L). The customer clearly stated the core requirements: First, it needs to be adapted to the strong corrosive environment with a pH value of 1-3 for the plating solution, and all components in contact with the liquid must have corrosion resistance; second, the equipment needs to meet the intermittent operation requirements of “once a week, 3m³ per batch”, and be adapted to the existing production process of the factory using a manual operation mode; third, the outflow mode is a dark flow to ensure a clean and leak-free filtration process.
After receiving the requirements, the Junyi technical team quickly conducted condition analysis and solution： For the strong corrosiveness of the plating solution， “all liquid-contact components are made of PP material” was set as the core design principle； combined with the customer’s manual operation requirements， a combination configuration of “manual feeding + manual pull plate + manual oil cylinder” was determined to reduce operation complexity and maintenance costs； for the processing capacity of 3m³ per batch， the filter plate size and quantity were optimized to ensure precise matching of filtration efficiency and processing requirements. The technical team transformed the customer’s requirements into detailed production technical documents， clearly specifying the materials and specifications of key components such as the frame， filter plate， pump body， and pipeline， and after confirmation by the customer， the production preparation was quickly initiated.
Precision customization： Full-dimensional quality control， ensuring adaptability to conditions
To ensure the stable operation of the equipment in the corrosive environment， Junyi implemented a full-process quality control in the production， strictly following customized standards from material selection to component assembly：
• Material precise matching： The frame is made of 316 stainless steel， balancing structural strength and basic corrosion resistance； all core components in contact with the plating solution are made of PP material – including QBK-25 type PP pneumatic diaphragm pump， PP conveying pipeline， 50mm thick PP material intermediate filter plate (7 pieces)， and PP-750AB type filter cloth (7+1 set)， starting from the source to prevent corrosion loss and extend the equipment’s service life；
• Configuration precise implementation： In accordance with the “box-type 380 type – dark flow” design requirements， complete the equipment structure assembly， the manual oil cylinder provides stable pressure， the manual pull plate is designed to adapt to the customer’s intermittent operation habits， 7 intermediate filter plates and 2 head and tail plates are precisely connected to ensure no leakage in the dark flow filtration， meeting the industrial production cleanliness requirements；
• Details strictly verified： After each equipment assembly， multiple rounds of tests were conducted for sealing performance， operation flexibility， and component compatibility， focusing on verifying the adhesion of PP pipelines and equipment interfaces， and the flatness of filter cloth installation， to ensure the reliability of the equipment operation in the corrosive medium environment， and all indicators met the standards before entering the production preparation stage.
Service guarantee： Efficient production， ensuring smooth export delivery
To ensure the equipment is delivered on time， Junyi established a special order follow-up mechanism to ensure the efficient progress of the order：
• Quick production response: After receiving an order, the production department prioritizes the allocation of raw materials and production resources, and proceeds with production strictly in accordance with the configuration list specified by the customer. The complete production and assembly of the complete machine and accessories (including the full set of filter cloth) are completed within the stipulated period, ensuring that the production progress precisely matches the delivery schedule;
• Professional export guarantee: Considering the transportation requirements for equipment exports, special wooden boxes are used for packaging, and the vulnerable parts of the equipment are reinforced and protected to effectively prevent damage from collisions during transportation; At the same time, the technical documents, installation instructions and other supporting materials for the equipment are sorted out to facilitate subsequent installation and commissioning by the customer;
• Full transparency communication: Sales representatives provide real-time updates on production progress, inventory status and logistics arrangements to the customers. In response to questions raised by the customers regarding export packaging, delivery time and other matters, professional answers are provided immediately, allowing the customers to fully grasp the order status and alleviate concerns about delivery.
As a professional manufacturer specializing in custom industrial filtration equipment, Shanghai Yuanyi has always focused on the special working conditions requirements of different industries. With the core advantages of “precise material matching, customized configuration, and efficient and reliable delivery”, it has won wide recognition from domestic and foreign customers. The successful inventory preparation of this Romanian order not only demonstrates the company’s deep understanding of the filtration scenarios for corrosive media, but also highlights Yuanyi’s mature capabilities in customizing export equipment and providing cross-border delivery services. In the future, Yuanyi will continue to focus on specific working conditions, optimize customized solutions, provide more targeted and reliable filtration equipment and services for global customers, and continuously expand the international cooperation map.
