Product Description

Specification

Brief introduction about high pressure die casting

Die casting is the process where molten metal is injected into a mold under high pressure in the range of 10 - 210 Mpa. This will result in a highly uniform casting with very good surface finish and exceptional dimensional accuracy. Usually this can either eliminate or greatly reduce the machining required to finish the part.We can offer both the cold chamber process and the hot chamber process. In the cold chamber process the metal is ladled into the injection chamber for each shot. There is less exposure of the molten metal to the chamber walls and plunger. This is very useful for aluminum and copper alloys that would easily alloy with iron at elevated temperatures. The hot chamber process has the injection chamber which is connected to the die cavity permanently immersed in the molten metal. The hot chamber process is used for metals of low melting point and high fluidity such as tin and zinc.
The materials that Donrex offers are alloys of aluminum, copper, zinc and magnesium. Zinc castings can be made with thinner wall thickness than aluminum due to high melt fluidity.
We can produce parts from very small to about 50 kg (110lbs ) for aluminum, 10 kg ( 22 lbs ) for magnesium, 80 kg ( 176 lbs ) for zinc and 10 kg ( 22 lbs ) for copper.

Material	Min. Thickness	Min. draft angle
Aluminum	0.9 mm ( .035 in )	0.5 degrees
Zinc alloys	0.6 mm ( .025 in )	0.25 degrees
Copper	1.25 mm ( .050 in )	0.7 degrees

Company advantages

Excellent dimensional accuracy:
Dimensional accuracy is typically 0.1 mm for the first 2.5 cm and 0.02 mm for each additional centimeter. 
Smooth surfaces:
Surface finishes of 1 – 25 μm.Production rate:
The production rate is dependent on cavitation, the number of cavities in a mold. One mold can complete 200 to 300 shots per hour.With smaller parts, it can increase to the thousands.
Detailed parts:
Reproduces any design down to the finest details with thin walls and structures.
Inserts:
Threaded inserts, bearings, and addons can be easily included.

Tensile strength:
Parts have tensile strengths of 60,000 psi or a 415 MPa.
Automation:
Hydraulic and pneumatic equipment are commonly used for efficiency and lower cost.

Tolerances:
Produces complex parts with extremely close tolerances.
