Raw Material of Copper Mould Tubes :-

To provide mould tubes with optimal physical and mechanical properties to customers' specifications, mould tube products are supplied of the following materials:

1. Cu-DHP: normally used for mould tubes section size below 180x180mm and round tubes below Dia.150mm.
2. Cu-Ag: normally used for mould tube section size above 180x180mm and round tubes above Dia.150mm.
3. Cu-Cr-Zr: Normally used for beam blank mould tubes

These materials have different levels of hardness and thermal conductivities. We are highly experienced in choosing proper materials to meet the specific demands in heat resistance and thermal conductivities of customers' applications. The physical and mechanical properties of these materials are compared in details in the following tables:

High Phosphorus Deoxidized Copper
Cu-DHP (Cu-0.03P)

Normal deoxidized copper.

Silver-Bearing Copper
Cu-Ag (Cu-0.1Ag)

Through the addition of about 0.1% silver, strength is significantly enhanced with no loss in thermal conductivity. Compared to deoxidized copper, the softening temperature is also about 100 degrees Centigrade higher than deoxidized copper

Cu-Cr-Zr
Cu-Cr-Zr (Cu-0.6Cr-0.15Zr)

Cr and Zr precipitation hardening provides this alloy with high strength, high resistance to heat, and thermal conductivity as high as high-phosphorus deoxidized copper.

TAPER

The Taper of Copper Moulds is of vital importance to the performance and life.
We supply Copper Moulds of best suitable tapers and stronger anti-wearing plating for copper mould tubes and mould plates.
Ranging from Single Taper, Double Taper, Triple Taper to Multiple Taper we supply all variants.

Each mould taper is tested by the computer-operated taper monitor and the taper graph for each mould tube is delivered along with mould tubes.

CHROME COATING

MOULD & PLATE COATINGS

As for the coating of copper mould plates, based on our years of experience, we are able to provide Chrome coating, Ni-Cr coating, Ni-Fe coating and Ni-Co coating to meet the demand of various customers.
