A manufacturer of automotive chassis rubber shock absorption components in Taizhou, Zhejiang, with 18 years of industry experience, mainly produces shock absorber buffer blocks, shock absorber isolation blocks, engine mounts, etc., applicable to both new energy vehicles and fuel-powered passenger cars. As a professional manufacturer deeply engaged in the industry, the enterprise has no basic production errors, but is restricted by problems such as process bottlenecks of traditional semi-automated core production lines and insufficient fine control capability of equipment, making it difficult to meet the high-end customization requirements of leading new energy vehicle enterprises. Combining the enterprise’s actual production needs and investment plan, Haifeng Automation customized a modular upgrade solution with a single model of equipment, in line with the enterprise’s demand for focusing on core production lines and phased upgrading. Without complex overhauls, the transformation of 2 core production lines for shock absorber buffer blocks was completed in only 5 months, focusing on optimizing the precision foaming and molding processes of high-value-added buffer blocks. The precise improvement of production capacity was achieved through standardized equipment upgrading, helping the enterprise successfully enter the supply chain system of leading new energy vehicle brands.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Located in Xianju County, Taizhou, the factory covers an area of 22,000 square meters and currently operates 4 semi-automated production lines, with a total annual capacity of 8 million units for all products and sales volume of 120 million RMB in 2024. Its core products mainly include polyurethane and rubber shock absorber buffer blocks, isolation blocks, mounts, dust covers, etc., among which shock absorber buffer blocks account for 45% of the total capacity with an annual output of 3.6 million units. The products are mainly supplied to distributors in East China, secondary suppliers of joint-venture automobile enterprises, and supporting manufacturers of some new energy vehicle companies. With the continuous improvement of leading new energy vehicle enterprises’ requirements for precision consistency, performance stability and full-process traceability\u00a0of chassis components, the fine production capacity of the enterprise’s core shock absorber buffer block production lines has become a key bottleneck for access to the high-end supply chain. To control upgrading investment and reduce the costs of equipment adaptation and operation learning, the enterprise is in urgent need of an automated upgrade solution with single model and high adaptability, to break through process bottlenecks while retaining the mass production advantages of the original production lines, and avoid the capital and management pressure caused by the investment in multiple models of equipment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Insufficient Precision<\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The traditional semi-automated pouring equipment of the core production lines has limited precision in raw material proportioning, with the parameter fluctuation of manual auxiliary debugging exceeding \u00b13% and insufficient heating uniformity of the temperature control system, leading to the dimensional tolerance of shock absorber buffer blocks fluctuating at \u00b11.2mm, far failing to meet the precision requirement of \u00b10.3mm of leading new energy vehicle enterprises. Due to higher requirements for density and rebound rate, high-end customized buffer blocks have great process control difficulty with a defective rate of 5.2%. The annual loss from rework and repair of high-end orders of the core production lines alone exceeds 5 million RMB, which has become a core obstacle to entering the high-end supply chain.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Low production line operation efficiency, large losses in process connection and product switching<\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The 2 core dedicated production lines for shock absorber buffer blocks adopt semi-automated segmented operation, with each process of pouring, molding and transfer requiring manual connection. Each line needs to be equipped with 5 workers for auxiliary operations, with a daily output of only 12,000 units per line, and the time consumed by process connection accounts for 20% of the total production time. In addition, the equipment has no standardized parameter preset module, and when there is an occasional demand for switching to produce buffer blocks of different specifications, it is necessary to manually re-debug core parameters such as pouring volume and temperature control curve, taking more than 2 hours for the entire process. The production line operation rate is only 70%, and the delivery cycle of high-end customized buffer blocks is easy to exceed customer requirements in peak seasons, affecting cooperation expansion.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Affected by the insufficient precision of pouring volume of traditional equipment and raw material loss in process connection gaps, the raw material loss rate of shock absorber buffer blocks in the core production lines reaches 7.2%, with an annual raw material loss cost of more than 2.4 million RMB for the 2 lines; the energy consumption design of old equipment is extensive, with a daily power consumption of 420 kWh for a single core production line, and the energy consumption cost is higher than the industry average; the VOCs collection efficiency of the traditional foaming process is insufficient, with the emission concentration close to the national standard limit, which requires additional investment to optimize environmental protection governance, further increasing production costs.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The production data of the core production lines is scattered in semi-automated equipment of each process, without a unified digital collection system, and needs to be manually summarized and entered into the production ledger, which is prone to data lag and incomplete information. It is impossible to realize full-process traceability\u00a0from raw material batches, production parameters to finished product delivery, failing to meet the digital management requirements of leading new energy vehicle enterprises for suppliers, and encountering obstacles in high-end supplier audits many times due to insufficient traceability capability.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In view of the enterprise’s upgrade demand for core production lines and investment plan of single model and high adaptability, the 2 core production lines for shock absorber buffer blocks are uniformly equipped with Haifeng JJF-G40 polyurethane medium-high pressure foaming pouring machines, with a metering accuracy of \u00b10.5% and matched with dynamic mixing heads with a rotating speed of 8000\u00b1200 rpm. The equipment is accurately adapted to the precision foaming production needs of conventional-sized high-resilience polyurethane buffer blocks, which can accurately control raw material proportioning and pouring volume, balancing mass production efficiency and product precision consistency. At the same time, the unified configuration of single model equipment greatly reduces the costs of equipment debugging, worker operation and later maintenance.<\/p>\n

The equipment is equipped with 20-station automatic turntable molding machines, which realize seamless connection with the original production lines, and realize integrated operations of automatic mold positioning, quantitative pouring and finished product transfer, completely eliminating the efficiency loss of manual process connection; the equipment has a built-in multi-specification parameter preset module, which can store core production parameters such as pouring volume, temperature control curve and foaming time of different specifications of shock absorber buffer blocks. When there is an occasional demand for product switching, the preset parameters can be retrieved with one click, skipping the link of repeated manual debugging, quickly completing operation switching, and increasing the operation rate of core production lines to more than 95%.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
