Permanent mold gravity casting

Permanent mold gravity casting may seem like a straightforward process, but a
high level of skill is required to maintain the quality of products. We follow a
series of strict procedures to ensure our products can always meet your
expectations.

Pre-casting preparations
To ensure smooth metal flow and minimal casting defects, we must first pre-heat the
casting mold to between 150°C (300°F) and 260°C (500°F). We then apply a ceramic
coating to the mold cavities to extend the mold’s working life and make it easier to
remove the casting parts.

Impeccable craftsmanship
It is worth noting that unskilled pouring may leave visible flow marks on the finished
parts. That is why we have our own casting specialists supervising the entire process,
ensuring the molten metal is poured into the mold at the right speed. After the casting
is done, all sprues and runners are accurately trimmed, then cleaned and painted (if
required) by an experienced crew of workers.

Guaranteed quality for our casting processes
Our gravity casting process can produce porosity-free parts ranging from 50 grams to
70 kilograms with good dimensional repeatability and a smooth finish. All material
specifications, dimensions and tolerances closely monitored and maintained by our QC
specialists.
