Metal Workings at Precious Goods
The scope of metal
works includes the following processes:
1. Metal Castings:
We have own foundry
facilities for making of casting steel, cast iron, ductile iron and stainless
steel. We also have the partner foundries for making brass, bronze
and aluminum castings. There are many casting processes, such as
green sand, sodium silicate, furan and alkaline-phenolic processes,
with both manual molding and automatic molding.
Some parts are exported
as raw castings, but some parts need to be machined. Machining processes
include turning, milling, CNC machining, etc. After machining, some
parts may require assembly to be finished products. Before shipping
the parts to customers, we will provide finishing or painting as
3. Heat Treating:
Most of casting products are heat treated. Heat treatment includes
stress relieving, quenching and tempering, normalizing, annealing, carburizing, nitriding, and
induction hardening. In house heat treating facilities include
annealing, normalizing, tempering, stress relieving and induction
hardening. For parts require special heat treating, such as
carburizing, induction hardening, atmosheric quenching, etc., we do
have professional heat treaters to support.
4. Fabrication Works:
Fabrication works mostly are made to order per customer's project.
Fabrication works include forming, welding and painting.
5. Other Services:
Not all works involve
only casting, machining and/or heat treating. Many works need some
special services, such as hard chrome plating, zinc plating,
galvanizing, power coating, aluminum anodizing etc. Those services
will be done by our associated partners at a reasonable cost
with a well accepted quality.
Our competitive edges:
1. Our works can be
started with a sample of product or a drawing.
2. We can also
provide some engineering modifications to suit customer needs for
special products or new models.
3. Our production
lead time is short.
4. We are flexible for the production volume. We can work for a
small volume, or for the first trial of products.
5. Our prices are
competitve for the required quality.
Any other services besides the above can also be requested.
