Product Details:

Sand Casting is a widely used metal casting process that involves creating a mold from a mixture of sand and a binder material. 

The process begins by creating a pattern, which is typically made of wood or metal, that is used to create the mold. 

The pattern is then placed in the sand and a flask is used to create a mold cavity. 

Once the mold has been created, molten metal is poured into the cavity. 

The metal is allowed to cool and solidify, and then the sand is removed to reveal the finished product. 

Sand casting is known for its versatility and Cost-effectiveness, as it can be used to produce complex shapes and large quantities of parts.

It is commonly used in the automotive and aerospace industries, as well as in the production of machinery and equipment. 

With the use of advanced technology and techniques, sand casting has become a highly efficient and reliable means of producing high-quality metal parts.

Development Drocess:

We can produce auto PARTS according to customer requirements, after receiving customer samples or drawings, first evaluate the production process of the product, and carefully calculate the cost of the product, under the premise of ensuring quality, select the manufacturing process at the lowest cost. After the manufacturing process is determined, the parts that need to open the mold need to be developed in the premise, because the opening time will generally be between 30-60 days, so as not to delay the delivery time. Product engineers who need to manufacture different processes will plan to decompose 3D and 2D drawings according to requirements, and formulate SOPs, while carrying out quality control, design and planning of inspection fixtures, APQP PPAP FMEA and other control plans, and deliver them to customers on time under the premise of ensuring quality. After the customer confirms that the product meets the requirements, it will be mass-produced.

Product Description:

Computer Numerical Control (CNC) Machining makes the machining process automated. The computer controller deciphers G-Code and M-Code (written programs) to determine tool path for selective material removal. Machining used to be a manual process which introduced a significant potential for human error. By making the process computer controlled, the machining is more consistent and lends itself well to mass production. SAIVS specializes in small to medium parts manufacturing, CNC turning, and CNC milling for the marine, telecommunications, transportation and auto industries to name a few. We always ensure that our customers receive machined components with absolute accuracy and within critical tolerances. SAIVS is experienced in machining both ferrous and non-ferrous metals. We have a wide range of machinery from, horizontal and vertical 4 axis machining centers, and 3 axis turning centers. Below are more specific details about our equipment.
