Model NO.: HZF-230 Delivery Date: 15-30 Days Trademark: HZF Specification: SGS/ISO HS Code: 84089452 Size: as Customer′s Inquiry Surface Finish: Customized Transport Package: Crate or Plywood Case or as Customers′ Request Origin: Shandong, China
Key Specifications/Special Features:
 

Materials	Made of stainless steel or alloy steel, many grades available
surface treatment	Good surface finish
Package	Normally packed with plywood box, special packing requirements accepted C & F, CIF or DDP terms accepted
two types of investment cast processes	They are the shell process and the water glass process
	The shell process is used to cast complex high quality parts with requirements of a very good surface finish and close dimensional tolerances
	The water glass process is typical of the process in the early stages of investment Castings It generally is capable of much larger castings than the shell process, but does not have as good of surface finish or tolerances The water glass process provides parts that have better surface finish and dimensional tolerances than sand castings

Inspection:
Inspection: in-house and third party
