1.    There are a variety of casting methods to produce aluminum die casting and magnesium alloy casting, because of the low melting point of aluminum and magnesium alloy. So in the design of their structures, you should consider which kind of casting method to cast this casting at first, in order to consider the relative structural manufacturability.
2.    The aluminum alloy and magnesium alloy casting should try to use thin wall structure, and strive to the balance of wall thickness. This is helpful to prevent shrinkage cavity shrinking and improve the strength of the metal castings. But you can also thicken some part for the unbalance of wall thickness to set feeding aluminum and magnesium alloy casting. This can help filling shrinkage to guarantee the quality.
3.    The aluminum and the magnesium alloy is easy for oxidation and suction. The density is small, so as to make the static pressure of the metal fluid is small and be difficult to exhaust. Therefore, aluminum and magnesium alloy casting is easy to generate hole and oxidation slag, reduce the mechanical properties and gas tightness. So designing the casting structure should avoid big plane, and the transition should be gentle, and avoid causing the turbulence of metal liquid.
4.    Because of the low melting point of the aluminum and the magnesium alloy, to those castings that have some certain gas tightness requirements, you should avoid using core support to fixed core when design.
5.    The compression strength of magnesium alloy is higher than its tensile strength. So you should adopt asymmetrical section and box to undertake the compressive stress.
6.    Pay attention to adopting the method of double metal die casting and potting casting to solve the problems in the structural design of the aluminum alloy and magnesium alloy.
7.    The corrosion resistant of magnesium alloy is poor. Often use surface treatment to improve the corrosion resistance of magnesium alloy castings.

Zinc Die Casting

We have been in the foundry business since 3 generations and are proud to keep this going. Our chairman Dr. Dinesh Patel founded the company Dr. Dinesh and Ramesh Eng. Pvt. Ltd. in Ahmedabad. The company covers a space of 10,000 sq. yards (comparable to cricket field) which is only 40% utilized giving us an undue advantage for growth. We have had several metal castings (Cast Iron, Stainless Steel, Aluminum) catering to International and Domestic Companies like Ingersoll Rand, ABB, TVS and many others. However, since a decade we have shifted our focus primarily on Aluminum Castings producing from 0.5 kg to 100 kg in permanent mold. We have been adding new processes such as

a) GDC (Gravity Die Casting)
Gravity Die Casting is the process of pouring liquid metal using Earth’s Gravity and hence it’s name. This method started on our end based on our customer’s demand leading us to develop a very difficult casting weighing almost 70 Kg in Permanent Mold for a German Company. Very few foundries can design this size of casting much less make it export quality. We are proud to say that soon we designed another such casting thereby establishing our niche in higher weight category giving an undue advantage for people with quality requirements in heavy castings.

b) Tilt Pour
In order to satisfy the demands of our customers from around the world as well as in the domestic market we developed the Tilt Pour technology providing, engineering as well as aesthetic parts. Due to our in house building of the machine we have significant control over machine. This helps to significantly improve the quality and speed of casting manufacturing as the functioning of the machine can be customized over several parameters. Final result – better lead times and consistent quality.

c) LPDC (Low Pressure Die Casting).
Our goal is to keep on adding newer technologies and keeping in line with this principle we added the LPDC technology to our belt. Often when X-ray quality castings, dynamic movement (high r.p.m) is a requirement or some other quality standards dictate the usage of LPDC.

In terms of our production capacity we have
Production Capacity: 2000 tons per year
Melting Furnances: 2
Holding Furnance: 5
