We (Jiangsu haohua industry group co.,ltd.)supplies the most common 45°elbow ,90°elbow and 180°elbow,the material is heat resistant alloy stainless steel,CAE Process Design Technology method or by Resin Sand Static Casting method Etc. under strict NDT tests like RT test.

CAE Process Design Technology

CAE is used to simulate temperature field distribution, mold filling and solidification processes. Through repeated design and verification, a precise top and bottom mold clamping design is adopted, and finally a reasonable pre-production casting plan is formulated.

Advantages

• Obtain the optimal casting process, ensure the stability of product casting, and improve the qualification rate of static castings;

• The cast products have a denser structure and more stable mechanical properties.

• Fundamentally eliminate the formation of cracks, shrinkage porosity and shrinkage cavities through process optimization, ensuring that product quality meets the requirements of design drawings.

Resin Sand Static Casting

It adopts the mixed molding of furan resin, curing agent and quartz sand, and is mostly used for casting complex large castings and static castings with a wall thickness greater than 15mm.

Advantages

• High mold strength, suitable for producing complex castings with large wall thickness;

• The mold cavity is brushed with zircon powder coating, which is heat resistant  and ensures excellent surface quality of castings.

• The molding sand has good collapsibility, easy cleaning and excellent formability, with low gas generation, good thermal stability and air permeability, which reduces casting defects such as sand adhesion, sand inclusion, sand holes, gas holes, shrinkage cavities and cracks.
