Material -- The Dige
products are that 100% with the pure copper casting, feel sink. The zinc
products casting is weight light in the market, plating turn white generally.
Zinc alloy is a characteristic of low density, many air vent, electroplate
layer easy to bubble, turn white and pollute the environment, does not accord
with the national standard either, at the same time of low grade. The copper is
the only callback nature metal, belong to the green products of environmental
protection. Electroplate Cohesion of copper higher than zinc alloy and
stainless steel, durable in use.
Copper tube -- Dige copper tube is in charge of in 1.0mm at least More than 5
mm.
Electroplate -- The Dige products must through pickle, copper plating, nickel
plating, polishing, and then chromium nickel plating. Plate chromium liquid
chemical material all adopt the import raw materials. It is less in above 25
micron for thickness to reach, and every trough products undergo acid
destruction testing more than 96 hours. The salt fog testing for more than 200
hours, is far higher than the international standard.
Polish -- The Dige products are from rough to process to polish, there are a
lot of processes, the polishing is seven, more than eight degrees. We check in
strictly, reaches 36 processes. Each process wants 100% to examine by staff,
quality examine person who examine 100% by herself, examine executive to
inspect by random samples. So our products all details are perfect.
