what is the minimum wall thickness for sand casting?
When it comes to sand casting, many people will be curious: What is the minimum wall thickness of sand casting? Generally speaking, the minimum wall thickness of sand casting is about 5 mm. If the wall is too thin, the liquid metal is prone to insufficient filling, pores, cracks and other problems during pouring and cooling, so 5 mm is a more reasonable and safe design reference. Of course, this value is not absolute. The specific situation depends on the type of material, casting size, design structure and casting process level. Sometimes, after special optimization, it can be thinner than 5 mm, but the process control requirements are very high.
Does it sound like sand casting is both simple and has a lot of knowledge? That's right! And fuding is experienced in this regard. Our factory focuses on the production of various sand castings, covering a variety of materials such as gray iron, ductile iron, carbon steel, stainless steel, etc. Whether it is conventional thickness or high-difficulty castings with demanding wall thickness requirements, we can easily handle it.
In terms of production equipment, fuding is equipped with multiple efficient and automated sand molding lines, with advanced melting furnaces, automatic sand processing systems, precision molding machines and complete post-processing equipment. The castings have precise size control, good surface finish and strong internal density. Whether it is used for large-scale mechanical equipment, engineering machinery accessories, or small high-precision parts in the fields of automobiles, energy, and mining, our sand casting can withstand rigorous testing and practical application tests.
Not only that, our technical team has rich project experience and can optimize the casting structure design and reasonably arrange the pouring system according to the customer's drawings and requirements to ensure stable casting quality and excellent performance. If the customer has special requirements, such as ultra-thin wall thickness, complex internal structure, or subsequent heat treatment and machining, we can also provide services.
For each batch of sand casting shipped from the factory, we will conduct strict quality inspections, including chemical composition analysis, mechanical properties testing, non-destructive testing, etc., to ensure that each product meets customer standards, truly polishing quality from details and winning trust from service.
