Sand casting is the most traditional and widely used casting technology: it uses quartz sand as the aggregate, mixed with binders such as clay, water glass, or resin to make sand molds (molds). The sand molds are for one-time use. Molten metal fills the cavity by gravity or low pressure, and after cooling, the sand mold collapses to obtain the casting. According to different binders, it can be divided into subdivided types such as clay sand, water glass sand, and resin sand.
The process is mature, with supporting supply chains worldwide, and the delivery cycle is short (mass production of small and medium-sized parts can be achieved within 7-15 days).
It is suitable for almost all metal materials (cast iron, cast steel, copper alloys, aluminum alloys, etc.), especially for difficult-to-form materials such as high-carbon cast steel;
The cost of sand mold materials is low (only 1/10 of that of metal molds), and it has significant cost advantages in single-piece and small-batch production (1-100 pieces);
There is no upper limit on the size of castings (it can produce large parts weighing over 100 tons) and it has strong adaptability to shapes (supporting complex curved surfaces and large wall thickness structures);

Founded in 1996, our company is an enterprise with nearly 30 years of successful operation in Qingdao City, Shandong Province, China. We integrate production and trade into one operation. Additionally, we have cooperative factories that can undertake outsourcing services such as electroplating and spraying.
You can send your drawings and data files to us via the email provided on our official website. If you do not have drawings or data files, we can discuss conducting on-site or cooperative mapping, and the results will be confirmed with you before proceeding.
We offer a full range of production services including:
• Casting
• Heat treatment
• CNC machining
• Assembly
• Surface treatment
Our company operates under the following international and national management systems to ensure quality and environmental compliance:
Quality management systems: ISO 9001-2015 and IATF 16949:2016
Environmental management systems: GB/T 24001-2016 / ISO 14001:2015
For product development, we strictly implement the five phases of APQP (Advanced Product Quality Planning):
Planning and defining the project
Product design and development
Process design and development
Product and process validation
Feedback, assessment, and corrective actions
Through the systematic planning and implementation of these five phases, the ISO 9001-2015 and IATF 16949 standards ensure full-process quality control from product design to mass production, thereby enhancing product reliability and customer satisfaction.
The sample lead time varies depending on the material and complexity of the product. In general: If the mold is provided by the customer or available for use, the sample lead time is 15-30 days. If a new mold needs to be developed, the sample lead time is 30-45 days.
