Our History:

1. Founding Period (1995-1998):
Established in 1996 in Pingdu City, Qingdao, China, the company initially focused on delivering high-quality precision casting solutions for the agricultural machinery and automotive axle industries. During this phase, it primarily manufactured small-scale precision castings using traditional silica gel precision casting technology.  

2. Technological Accumulation and Expansion (1998-2014):
In 1998, the company introduced advanced investment casting and sand casting technologies, enabling the production of medium and large-scale precision castings. In 2006, it successfully obtained ISO9001 certification, ensuring consistent quality and reliability in its casting products. Between 2009 and 2014, the company significantly expanded its production facilities, added multiple new production lines, and adopted efficient casting processes, thereby enhancing its production capacity to meet the demands of diverse, multi-batch, and customized product manufacturing.  

3. Brand Marketing (2016-2020):
In 2016, the company began prioritizing brand building by actively participating in domestic and international industry exhibitions to enhance brand recognition. In 2017, it expanded its global market presence and established long-term cooperative relationships with overseas customers. By 2020, the company had successfully developed multiple patented technologies, further improving product precision and quality.  

4. Technological Innovation and Sustainable Development (2018-2024):
In 2018, the company invested in establishing a dedicated research and development center focused on the exploration of new materials and processes. In 2019, it developed an environmentally friendly precision casting process that effectively reduced pollution emissions during production while significantly improving the quality of surface and internal defects in castings. In 2020, the company was officially recognized as a national high-tech enterprise, underscoring its achievements in technological innovation.  

5. Intelligent Manufacturing and Future Vision: In response to the challenges posed by the global pandemic in 2019, the company swiftly adjusted its market strategy, strengthening online marketing and service capabilities to ensure stable business growth. In 2021, it launched an intelligent manufacturing initiative, integrating automation and information technology to enhance production efficiency and management capabilities.  

6. Looking Ahead: The company remains committed to its innovation-driven development philosophy, striving to secure a leading position in the global precision casting industry.


 


1, Casting process optimization category
Q: How to solve the problem of cracking in thin-walled die-casting products?
Suggest controlling the proportion of recycled materials to ≤ 30%, calculating the mold retention time based on a wall thickness of 1mm/3s, controlling the ejection delay within 0.5-2 seconds, and optimizing the mold cooling system.
2, Equipment and operation category
Q: How to handle emergency situations when the injection head is stuck in the goose neck area?
After the equipment cools down, try rotating the hammer head. If it cannot be rotated, replace the driver cylinder; Long term solution: It is recommended to upgrade the material of the material pot and regularly clean impurities.
Q: Is there intermittent discharge during material feeding?
Check if the nozzle is blocked (the gray section indicates blockage), which can increase the nozzle temperature by 5-10 ºC, shorten the nozzle departure time by 0.1-0.2 seconds, and moderately reduce the flow rate of the fixed mold cooling water.
3, Materials and Surface Treatment
Q: Does the casting have pattern defects after anodizing?
Adjust the uniformity of injection oil spraying and optimize the high-speed injection switching position; Regularly check the copper ion concentration in the oxidation tank (recommended ≤ 20ppm)
4, Mold maintenance category
Q: What should I do if the mold frequently sticks to the material?
Comprehensive solution: Reduce pouring temperature by 20-30 ºC Use polymer release agent Polish the surface of the mold cavity (use with caution for nitriding molds) Optimize sprue design to reduce metal liquid flushing
