The quality requirements standard basically covers the entire manufacturing process of hydraulic castings. They can help foundry enterprises to understand the quality requirements of hydraulic castings, so as to ensure the quality of hydraulic castings. Therefore, understanding the quality requirements and standards is the basis for casting enterprises to ensure the quality of castings.

Standard strategy for quality requirements of hydraulic castings

The quality requirements standard basically covers the entire manufacturing process of hydraulic castings. They can help foundry enterprises to understand the quality requirements of hydraulic castings, so as to ensure the quality of hydraulic castings. Therefore, understanding the quality requirements and standards is the basis for casting enterprises to ensure the quality of castings.

The quality requirements of castings can be divided into two parts: one is about the performance requirements of castings, and the other is about the manufacturing requirements of castings.

1. performance requirements

The performance requirements of castings include: structure size, material properties, surface quality, strength, corrosion resistance and wear resistance.

1. Structural size requirements

The structural size requirements are the basic requirements of hydraulic castings, including external dimensions, aperture dimensions, groove dimensions, cavity dimensions, etc.

2. Material performance requirements

Material performance requirements are important, including the type of hydraulic casting material, material grade, material tensile strength, material elongation after fracture, etc.

3. Surface quality requirements

Surface quality requirements include surface hardness, surface finish, surface roughness, surface relative humidity, surface color, etc.

4. Strength requirements

Strength requirements refer to the tensile strength, compressive strength, pull-out strength, bending strength, etc. of hydraulic castings.

5. Requirements for corrosion resistance

The corrosion resistance requirement refers to the corrosion resistance of hydraulic castings, which can be determined according to the use environment of hydraulic castings.

6. Wear resistance requirements

Wear resistance requirements refer to the wear resistance of hydraulic castings, which can also be determined according to the use environment of hydraulic castings.

2. manufacturing requirements

The manufacturing requirements of hydraulic castings include: melting temperature, slag liquidpH value, gate position, casting structure size tolerance, slag fluidity, slag state, etc.

1. Requirements for melting temperature

The melting temperature requirement is the basic requirement of casting, and its value determines the formability and structural performance of the casting.

2. Requirements for pH value of slag liquid

slag liquidPH value is a very important indicator in the manufacturing process of hydraulic castings, which can affect the surface quality and strength of castings.

3. Gate location requirements

The correctness of the gate position directly affects the structural size and structural performance of hydraulic castings, so the gate position requirements are particularly strict.

4. Dimensional tolerance requirements of casting structure

The dimensional tolerance of casting structure is a very important index in the manufacturing process of hydraulic castings, which can affect the external dimensions and functional properties of castings.

5. Fluidity requirements of slag

Slag fluidity is a very important index in the casting process, which can affect the structural size and structural properties of castings.

6. Requirements for slag state

The slag state is a very important indicator in the manufacturing process of hydraulic castings, which can affect the structural size and structural properties of castings.

The above is about the quality requirements of hydraulic castings standard strategy, we hope to help. In order to better ensure the quality of hydraulic castings, foundry enterprises should not only be familiar with the quality requirements of hydraulic castings, but also strictly check every link of the production process.
