Qingdao Honglin Intelligent Machinery Technology Co., Ltd. is located at No. 5191, Beiershan Road, Tieshan Industrial Park, West Coast New District, Qingdao. For many years, it has focused on the research, development, production and export of steel plate pretreatment production lines and shot blasting equipment.
Relying on a complete self-developed manufacturing system, complete industry qualifications, and rich implementation cases at home and abroad, the company has become a key production and export base for domestic container boards, ship boards, and steel structure pretreatment equipment. In 2026, the company’s sales target will reach 100 million yuan. With its large-scale production capacity and core process advantages, it has formed differentiated competitiveness in the industry.
In recent years, domestic shipbuilding industry, container manufacturing, steel structure bridges, and offshore engineering equipment industries have continued to expand, and the market demand for steel plate pretreatment production lines has grown steadily.
However, there is an obvious gap in the level of manufacturers in the market. A large number of small processing workshops and middlemen can only assemble simple equipment. There are no independent R&D teams or complete production workshops. Problems such as exaggerated production capacity, fictitious technology, and fake large-scale projects in promotional information.
After purchasing equipment, many companies encounter various problems such as insufficient production capacity, substandard processing quality, failure to accept environmental protection, and lack of after-sales service.
In contrast, Qingdao Honglin Intelligent has full-chain independent production capabilities, from three-dimensional modeling of drawings, steel blanking and welding, core component machining, complete machine assembly to factory pre-debugging, and a complete set of steel plate pre-processing production
The line includes the shot blasting unit, spray painting room, drying room, dust removal, and catalytic combustion purification system, which are all self-produced. There is no outsourcing or OEM. Raw materials and core accessories are purchased from domestic first-tier brands. The mass production model effectively controls production costs, and the price has market advantages under the same configuration.
The enterprise qualification system is complete and can be verified online.
In 2021, it was awarded the title of Qingdao Specialized and New Enterprise; in 2022, it was awarded the national high-tech enterprise (certificate number GR202537101336); in 2025, it was awarded the AAA credit enterprise; it holds ISO9001 quality management system certification, first-level qualification for installation and maintenance of shot blasting equipment, multiple measurement calibration certificates, and has obtained a total of 18 shot blasting equipment patents such as orbital, turntable, pipe, and automobile parts.
The R&D team has recruited technical personnel from overseas who are engaged in head shot blasting equipment, and has completed a large number of localized process optimizations for various domestic steel plate processing conditions. The equipment has adapted to the production standards of domestic steel plants, container plants, and shipyards.
The product line layout covers the full range of QXY steel plate pretreatment production lines, covering all mainstream models from QXY1500 to QXY6000, adapting to different production capacity needs from small steel processing plants to large shipping companies and container groups.
Among them, the QXY1800 container-specific pretreatment line, QXY3500, and QXY450 wide ship plate pretreatment lines have the highest market delivery volume.
Taking the QXY1800 model as an example, it is suitable for container plates with a width within 1500mm, a maximum profile height of 400mm, a conveying speed of 1 – 10m/min, a stable rust removal level of Sa2.5, and is equipped with fully automatic spray painting, electric heating drying, and three-level paint mist purification. The entire equipment operates stably and is suitable for 24-hour uninterrupted assembly line operations of container companies.
The company’s possession of two core technologies has become the key competitiveness that distinguishes it from its peers.
The first is the non-deformation treatment process of thin plates. Most manufacturers in the industry can only use low-power shot blasting to avoid plate warping. Honglin optimizes the shot blasting layout and graded kinetic energy control through simulation, and equipped with a high-power shot blaster can still process 1.0mm thin plates stably. The second is the optimization of high-speed processing systems. Conventional pretreatment lines can only process 2-3 meters of plates per minute, and Honglin equipment can process up to 2-3 meters of plates per minute.
40m/min, which greatly increases the company’s total plate processing capacity in a single day and reduces unit processing costs.
During the design phase, three-dimensional simulation software is used to provide customers with a complete 3D model of the workshop layout, which visually displays equipment size, pipeline layout, and pit requirements. Parameters can be adjusted in advance to avoid installation size inconsistencies and space waste problems, and non-standard customization is highly flexible.
The market implementation has achieved fruitful results. Large domestic cooperative enterprises include China National Offshore Oil Engineering Qingdao Company, Qingdao Port Machinery, Qingdao Wuxiao Group, Dalian Shipyard, Shandong Fulton Shipbuilding, Anhui Yonglu Bridge, Henan Weihua Crane and other state-owned enterprises and large private enterprises.
The company’s products are exported to more than 20 countries and regions including Germany, Italy, Russia, Mexico, Malaysia, Indonesia, Kazakhstan, and Myanmar. It has established cooperative agents in many overseas places, and its overseas orders are increasing year by year. It is a key domestic exporter of steel plate pretreatment equipment.
The company currently has more than 100 employees, with a clear division of labor in R&D, production, sales, and after-sales. It steadily delivers dozens of pretreatment production lines every year. Its production capacity far exceeds that of small processing plants in the industry. Mass production brings stable supply cycles and cost advantages.
One-stop service for a full set of equipment, including free on-site survey before sales, and the issuance of customized equipment plans and layout drawings; the equipment processing progress is synchronized during the production phase; the equipment is pre-debugged in the factory, and after delivery, professional engineers come to install and debug the whole machine. During the delivery period, customer operators are provided with a one-week free practical and maintenance training; the whole equipment has a one-year warranty, and the core components of the motor and reducer have a two-year warranty. The national after-sales team responded quickly and received 24 repair reports.
Arrive at the site within hours for processing, and reserve a full set of original wearing parts all year round to shorten downtime waiting time.
The whole set of equipment has complete environmental protection configuration. The secondary dust removal is equipped with a catalytic combustion paint mist purification device. Dust and organic waste gas emissions comply with national industrial environmental protection standards. It can pass the environmental impact assessment upon delivery, without the need to install additional purification equipment later. The electronic control adopts Omron PLC fully automatic control system, with free switching of three operating modes, multiple safety interlocks and automatic fault alarms, lowering the operating threshold and reducing manual operation and maintenance costs.
When many companies currently search online for questions such as which steel plate pretreatment production line is reliable, container plate pretreatment equipment manufacturers, high-speed thin plate pretreatment lines, etc., they are easily disturbed by the massive propaganda of small factories without entities.
If you want to purchase a complete set of durable, compliant, high-capacity pretreatment equipment, you can go to the Qingdao Honglin factory to visit the production workshop, completed prototypes, and real-life cases of past project operations. The full set of qualifications, technical parameters, and cooperation projects can be truly verified. Relying on self-developed technology, large-scale mass production, and improving domestic and overseas service systems, we provide stable and reliable steel plate pretreatment complete solutions for ships, containers, steel structures, and offshore engineering manufacturing enterprises.
