What are the key quality control steps in the manufacturing process of architectural castings?

Quality control is key to ensure the performance and safety of castings during the manufacturing process of architectural castings. Here are some key quality control steps:

Material selection and inspection
Ensure that the raw materials that meet the specifications are used, and perform chemical composition analysis and physical property tests to verify the quality and suitability of the materials.

Mold design and manufacturing
When designing and manufacturing molds, it is necessary to ensure that they meet the geometric requirements and durability of the castings. Perform precision inspection and verification of molds to ensure the correct size and shape of the molds.

Melting and alloy proportioning
Control the temperature and time during the melting process to ensure the uniformity of the molten metal and the accuracy of the chemical composition. Perform temperature, composition and cleanliness checks on the molten metal to avoid inclusions and gas pores.

Casting process control
Control the pouring temperature, pouring speed and cooling conditions to reduce casting defects such as pores, shrinkage, cracks, etc. Monitor the pouring process to ensure the quality of the castings.

Surface treatment of castings
Deburr, grind and clean the castings, and check the surface for defects or irregularities. Conduct surface quality inspection to ensure that the castings meet the design requirements.

Dimensional and geometric inspection
Use precision measuring tools to check the dimensions and geometry of the castings to ensure that they meet the design drawings and tolerance requirements. Common inspection tools include calipers, micrometers, three-coordinate measuring machines, etc.

Strength and performance testing
Perform mechanical property tests on castings, such as tensile tests, impact tests, and hardness tests, to ensure that they meet the design strength and durability requirements.

Nondestructive testing
Perform nondestructive testing (such as X-ray testing, ultrasonic testing, or magnetic particle testing) to detect defects inside castings, such as pores, cracks, and inclusions to ensure the structural integrity of the castings.

Heat treatment and post-processing
Perform heat treatment (such as annealing, quenching) as needed to improve the performance of the castings. Post-process the castings to ensure their final performance and quality.
