Die Casting’s Blog

ruyi iron casting Foundry employees conduct quality control tests from the start of the production process to the completion of the casting process.

Sand Lab
Before we use green sand for mold development, we test it in our sand lab for strength characteristics and compactability from the start.

Metals Lab
We conduct a variety of tests in our Metals lab during production and the testing results are then reported to our Gray Iron Casting customers.

Metals lab testing services we provide include:

Evaluating the molecular structure of a casting section using a Unitron MEC 8484 stereomicroscope.
Evaluating the thickness of casting walls by measuring and verifying the thickness using a Kraut-Kramer DML-4 ultrasonic thickness gauge.
Verifying the tensile strength of the casting using a Detroit tensile strength test machine to perform mechanical performance tests.
Verify the chemical composition of the die casting using spectrometer.
Shop Floor
ruyi Foundry personnel conduct a number of tests on the shop floor during production and the testing results are then reported to our Gray Iron casting customers.

Shop floor testing services include:

Hardness testing using a Tinius Olsen Brinell variable load hardness test machine,
Pyrometric testing using an Ircon optical pyrometer located at the Disamatic molding machine to measure and verify the temperature of the molten Gray Iron being cast, and
Mold hardness testing using a Dietert Mold hardness tester to ensure the molds have hardened enough to accept the molten Gray Iron and not deform.
