The range of metal castings poured at
Precious Goods can be categorized in general as
1. Cast Irons:
Range of cast irons from FC15 to FC30 (JIS
Standards.) Sand molding with green
sand, sodium silicate, furan (no-bake) and full-mold (Foam Pattern.) Melts are
controlled with CE Meter and Spectrometer Analysis. Weights can be
less than 1kg up to 3000kg. For high-volume cast iron parts,
the molding can be done with Automatic Molding Lines
(either verical molding with Disamatic, or horizontal molding.)
2. Ductile Cast Irons:
Ductile cast irons, or spheroidal graphite irons, range from FCD40 to
FCD60 (JIS Standards.) The sand molding operation uses the
same line as cast iron molding lines, with manual or automatic molding. The
compositions are controlled with CE Meter and Spectrometer Analysis.
Microstructure analysis and Tensile Test
are also performed regularly. Weights can be
less than 1kg up to 3000kg.
Steels include low and medium carbon steels, low alloy
steels and high alloy steels. Sand molding with Sodium Silicate and
No-Bake. Foam pattern is another option. High manganese steels
for mining services are one of our products. Practically, any
steel standards can be made here. Steel casting is one of our
4. Stainless Steels:
Stainless steels range from popular grade Austenitic Stainless
Steel SUS304 to Hardenable Martensitic Stainless Steels.
5. High Alloyed Cast Irons:
This is a special group of cast irons. Mainly used in specific
conditions require wear resistance, high temperature service,
corrosion resistance, etc.
