In the automotive industry, headlights have evolved from lighting components to important safety and design components. In Yantai, Shandong and Taizhou, Jiangsu, Tianming Precision, a company with nearly 50 years of experience in the automotive lighting industry, is working together with long-term partner WINTEC to tackle manufacturing challenges.
The optical components of car lights have strict manufacturing requirements, such as light guide strips, which require high quality inspection by the host factorySegmented electrical inspectionThe optical lumen value of each segment is required to be above 5000, and the uniformity requirement is extremely high, resulting in a tight shipping cycle. There are not many injection molding factories that can stably undertake such orders.
Tianming is one of them.
From bicycle taillights to smart headlights: a leap forward
Three generations of industrial upgrading
The story of Tianming began in the 1970s, with its founder Yu producing reflective taillights for the "Phoenix" and "Forever" national bicycles. In that era, "durability" and "functionality" were the highest standards, and thus the primitive belief in stability and precision was engraved into the corporate DNA. At the turn of the century, with the development of China's automobile industry, Tianming shifted its focus from the second generation leader Wei Dong to precision injection molding of car lights, focusing on high difficulty categories such as transparent, thick walled, and reflective, which are widely recognized in the industry. In 2021, the third generation manager, Shan Shan, promoted the production of a new factory in Taizhou, Jiangsu, serving top suppliers such as Xingyu Automotive Lights, with terminal coverage of brands such as BMW, Audi, NIO, and Ideal.
As the customer hierarchy increases, manufacturing challenges also increase. The injection molding workshop of the new factory in Taizhou is equipped with a 130 ton e-win systemelectric motorMore than 20 WINTEC injection molding machines, including a 1050 ton T-win hydraulic two plate machine for producing thick walled light guides for headlights/taillights.
Why choose WINTEC
The optical components of car lights are a difficult field in precision injection molding, especially for light guide strips and thick walled parts, which face three major engineering challenges:
Challenge one, optical uniformity - the requirements for precision and stability are quantified by "segmented electrical inspection".Each section of the light guide should have a lumen of over 5000.
Challenge 2, Internal Stress Control - The pressure holding window of thick walled components needs to be precisely controlled, otherwise hidden defects may occur.
Thirdly, weight consistency.The weight deviation of each module needs to be extremely small to ensure the stability of the entire batch of optical data.
These three challenges place high demands on the long-term stability and consistency of the equipment.
Device selection logic with 'configuration priority'
In 2014, ENGEL Changzhou factory launched the WINTEC brand. As a loyal customer of ENGEL, Weidong and Shanshan went for inspection, focusing on equipment configuration, manufacturing process, and quality standards. According to Shan Shan's recollection, "We conducted a comprehensive examination of the machine's performance and parameters, and confirmed that it was at ENGEL level. ”
Tianming subsequently purchased the first WINTEC equipment in Shandong Province and gradually increased its purchases. Years of use have verified its process stability, repeatability, and low failure rate. When the new factory in Taizhou was built in 2021, WINTEC was once again introduced in bulk as its main equipment in the injection molding workshop.
IQ weight control: effectively controlling weight fluctuations
Tianming believes that high-quality production is the result of systematic engineering, rather than being determined by a single device. Therefore, in addition to purchasing injection molding machines, Tianming also attaches great importance to supporting training, processes, software, and other aspects.
The iQ weight control intelligent weight control module plays a key role in meeting the precision requirements of optical components. It can monitor key parameters in real-time and automatically adjust them during the production process, compensating for environmental humidityraw materialWeight fluctuations caused by factors such as batches and temperature differences. General Manager Teng Bin introduced, "After enabling this module, the final yield rate can reach over 98%, and each segment of the segmented electrical inspection meets the standard of over 5000. This is an important reason why customers trust Tianming
Tianming's Equipment Perspective:
Pay attention to the long-term total cost of ownership (TCO) of the equipment
As Wei Dong pointed out, "Profit must be 'made' from production. Quality must be high to qualify for entry, but prices must be low, delivery must be fast, and long-term stability must be maintained. Profit can only come from refined production management
Shan Shan added, "Time is measured in seconds, weight is measured in grams, and profit is measured in cents." Tianming has always practiced the concept of "purchasing equipment not only depends on configuration, but also on long-term holding costs. The price of a single machine is only one aspect, and yield, energy consumption, failure rate, data integration, and training need to be taken into account. Insufficient stability leads to customer loss, waste loss, delivery delay... These hidden costs are often higher. Good equipment ultimately leads to a stable increase in yield rate by two points, and profits naturally arise
The data from Tianming Taizhou Factory shows that the yield rate of transparent thick walled parts is stable at over 98%, and the optical and electrical inspection sections meet the standards; Long term performance of energy consumption is good; WINTEC equipment has almost zero failures and significantly improved OEE; The data interface can be stably integrated with Tianming's self-developed MES.
For Tianming, WINTEC is not only a supplier, but also a partner. According to Shanshan.
Compound interest for three generations
Constructing competitive barriers through the use of Weidong's technical expertise; Used by Shan Shan's generationDetail view, data view, and pattern viewThe management system will further enhance quality and business depth.
WINTEC's position in this system is the result of ENGEL's more than 80 years of technological accumulation, the ability of iQ weight control to stabilize weight in fluctuations, and the confidence that every product on the Taizhou new factory production line can withstand customer testing.
From Tianming's story, we can see that in the upgrading of intelligent and digital high-end manufacturing, reliable long-term process stability and precision engineering capabilities are the foundation for enterprises to achieve sustainable development.
From Yantai to Taizhou, from one to over twenty units. Three generations have persisted in doing one thing for half a century - stability, which is the greatest compound interest.
