Casting Services


Casting operations and services are as following:

  • Sodium-Silicate Molding

  • Green Sand Molding (Manual and Automatic)

  • Furan (No-Bake) Process

  • Investment (Lost Wax) Castings

Pouring is done with induction furnaces for sizes up to 3 tons.

Special large-sized cast irons can be poured with use of cupola furnaces.

Chemical compositions are checked with spectrometer analysis.

Other mechanical properties are tested according to customer requirements, such as tensile properties and hardness.

The range of metal castings poured at Precious Goods can be categorized in general as following.

1. Cast Irons:
Range of cast irons from FC15 to FC30 (JIS Standards.) Sand molding with green sand, furan (no-bake) and full-mold (Foam Pattern.) Melts are controlled with CE Meter and Spectroanalysis. 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 also controlled with CE Meter and Spectroanalysis. Weights can be less than 1kg up to 3000kg

3. Steels:
Steels include low and medium carbon steels, low alloyed steels and high alloyed 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.

4. Stainless Steels:
Stainless steels range from popular grade Austenitic Stainless Steel SUS304 to Hardenable Martensitic Stainless Steels. For precision and small parts, we offer lost wax or investment casting.

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.
