Zinc Die Casting

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

Type of Castings

Different Types Of Casting To Suite Your Casting Necessity

There are different processes that can be used in creating complex shapes of metals parts and one procedure is through casting. Casting is a manufacturing method wherein a liquid material is transfer

red into a mold, usually following a hollow cavity of the desired shape, and then allowed to solidify afterwards. It has been used even in the past and one example or type of casting is die-casting.

The die casting method is a process of forcing molten metal under high pressure into mold cavities similar to permanent mold casting. It best suites the purpose of making small to medium sized parts fashioned with good and precise details. By-products of this method are furnished with fine exterior finish and dimensional accurateness. Most materials used in this method are metals such as zinc die casting, copper, and aluminium die casting and magnesium die casting.

Another form of casting which is considered to be the most popular and simplest type is sand casting. It is a technique that has been used for many centuries now. Sand casting is a process of forming a mold out of a sand mixture through pouring a casting liquid into a desired shape. This type of casting allows manufacturers to create large number of products in such a small range of production expenses. Most metals are caste depending in the type of sand used for the molds in this method.

An additional process that can be also used is Plastic molding. It is a manufacturing technique in making parts from both thermoplastic and thermosetting plastic materials for production. It includes plastic injection molding wherein molten plastic is injected at high pressure into a mold, which is the opposite from the product’s actual shape. Example by-products of this method are bottle caps and outdoor furniture.

Moreover, a further technique is cold forming. It is also known as cold forging. Cold forming is a manufacturing procedure in which a metal is shaped at an ambient temperature to produce metal components in a definite shape. The techniques usually involved in this procedure are bending, cold drawing, cold heading, coining extrusion, thread rolling and others.

Some benefits of cold forming are enhancements in the component properties of the product because the grain structure of the material is being elongated during the formation process wherein it is forced to follow the structure and as a result its’ strength is increased. Another benefit of cold forming is that the aesthetic finish of the components gives out a brighter facade and formed with a consistent high tolerance. These somehow reduce the necessity of complex finishing and polishing.

These are only some of the different kinds of casting. Other types of casting aside from die-casting, cold forming and sand casting of metals are plaster casting, shell molding, investment casting, permanent mold casting, centrifugal casting, continuous casting and casting of plaster, concrete, or plastic resin. Each type of technique has specific and unique routine that allows you to produce superior outcome and high-quality by-products to best suite all your casting needs for your manufacturing use.

Metal Casting

What Is Casting?

Metal casting is an ancient technique that has a variety of applications and purposes. Civilizations from the dawn of time to present day have used metal working as a way of creating artistic, religious, and practical items. The process of metal casting involves melting metals at high temperatures and using molds to then shape the metal into new items. The furnaces used in metal casting helped pave the way for the Industrial Revolution, without which the course of history would be dramatically different. Metal casting is just one form of metal working that has seen a recent surge in popularity as resources are becoming more affordable and communities are springing up to share information, ideas, and projects.

Casting Mold Technology

There are three main forms of Casting Mold failure

1 thermal fatigue crack damage failure

Thermal fatigue cracking failure of die casting production, mold repeatedly stimulated cooling and heating effect, the molding surface and internal deformation are involved, and the repeated cycles of thermal stress, leading to tissue structure of two injury and loss of toughness, causing cracks appeared, and continue to expand, once a crack expanding, and molten metal liquid impact, coupled with repeated mechanical stress crack accelerated expansion. Therefore, on one hand casting mold must be fully preheat starting. In addition, in the production of the die casting die in must be kept in a certain temperature range, so as to avoid the early cracking. At the same time, to ensure the mold production and manufacturing of internal no problem. Because of the practical production, the majority of the ineffectiveness of the die thermal fatigue cracking.

Aluminum Motorcycle Parts

One of the best reasons to get an aluminum motorcycle hitch carrier is because they are so reasonably priced. Compared to a standard trailer, they are much more affordable and do the same job. As long as you only need to carry one motorcycle, you simply don’t need a large trailer. A hitch carrier provides plenty of room at a fraction of the price.

You may be wondering-why Aluminum Casting? While there are other types of materials available in hitch carriers, there are many reasons to choose an aluminum motorcycle hitch carrier. Aluminum is just as strong as other types of metal. But it is also much lighter than almost any metal available today. That means you won’t be wasting gas towing the hitch carrier, you’ll only be towing your bike. Aluminum won’t add extra weight to your car, truck or SUV. Read more

Aluminum Castings

Best Designs of Cast Expo ’08

The Cast Expo ’08 recognized the most effective and innovative cast designs developed during the last year. Nine cast components were selected as the best designs of the year by the 2008 Engineered Casting Solutions and AFS Casting Competition. The AFS nominated an overall winner, 4 Best-in-Class winners, and 4 honorable mentions.

An oil tank for Harley Davidson, developed by the Carley Foundry Inc. in Blaine, MN, was named as the winning product. The product houses and circulates oil across the new Harley Rocker’s operating system, and it is a critical element of the cycle’s cosmetic look. The product was cast in A356-T6 aluminum using semi-permanent molding and weighs 9.25 lbs. In addition to its aesthetically pleasing design, it provides superior heat resistance than the available options – a plastic design and a multi-piece fabrication. Read more
