Dr. Dinesh & Ramesh Engineers Pvt. Ltd

Vatva, Ahmedabad, Gujarat

DRE has been able to serve the Textile industry very closely since it is located in Ahmedabad, India – which is known as the Manchester of the east. We have been able to provide various parts for carding machine manufacturers – which are used for detangling of the fibres to produce a continuous sliver. We have also been able to provide for the spinning industry various parts – including specialized flyers for the Jute industry. We specialize in making parts for the Textile industry and are aware of the various quality requirements thereof. At DRE we have been able to manufacture parts upto 100 kg for the textile industry and in various shapes and sizes. Below are a few examples of the parts we have developed.

Dr. Dinesh & Ramesh has catered to parts from industries including recreational, lighting, healthcare, aesthetic & commercial amongst other industries. We can fulfil the requirement of Aluminium castings for any industry and deliver fully machined castings as per their requirements.

Dr. Dinesh & Ramesh Engineers has considerable experience for the development of castings for the Petroleum industry. We have developed various parts like filters, base boxes, covers, nozzles etc. for the industry.

Gravity Die Casting is a process in which molten metal is poured in a metal mould (usually of iron) under the working of gravity. Since the metal enters the mould under the influence of gravity the process is called as Gravity Die Casting (GDC). Permanent mold is another name for Gravity Die Casting primarily used in USA and Canada. Compared to sand castings, gravity die casting permits the production of more uniform castings, with closer dimensional tolerances, superior surface finish, and improved mechanical properties. Metals that can be cast in gravity die casting include Aluminium, Magnesium, Zinc and copper alloys, and hypereutectic Gray Iron. Dr. Dinesh & Ramesh Engineers (DRE) are experts at producing pressure tight, leak proof, intricate shaped large gravity die castings. We are able to achieve parts from 0.5 kg to 100 kg in gravity die casting.

In this process, a metal mould/die is mounted on above a sealed furnace containing molten Aluminium metal. A riser tube connects the bottom of the die to the molten metal bath. The sealed furnace containing the molten metal is pressurised (typically 3-35 psi), and the metal is forced up into the mould/die slowly at a steady predetermined rate. It is important to determine the rate of filling to avoid entrapment of air and turbulence giving homogeneous defect free parts. The pressure is usually given to feed the defects like shrinkage normally associated with casting process. Once the casting has solidified (time duration 1-4 minutes typically), the pressure is released and the molten metal falls back into the bath, and the casting is ejected. Then the preparation for the next cycle begins. There is very high yields 90-95% in case of Low Pressure Die Casting leading because in effect the casting in a way acts as the gating system. Dr. Dinesh & Ramesh has set up their proprietary Low Pressure Die Casting system. Our system caters to parts from 0.5 kg to 25 kg in LPDC. The parts developed in Low Pressure offer advantages to other systems in homogeneity, yield (lowers process cost), strength as compared to other casting processes.

The Auto Industry is growing at a fast rate in Gujarat and  neighbouring  areas with very high local deman

Dr. Dinesh & Ramesh Engineers Pvt. Ltd. caters to various parts for equipments of pressure moulding machines in the plastic industry alongwith various accessory parts including conveyor body and parts used in chilling equipment.

At Dr. Dinesh & Ramesh Engineers we are able to produce pressure tight parts, high strength and helium leak proof parts which is the order of the day for the Electrical Industry today. We have employed new techniques to achieve these criterias and keep on improving our methods to cater to this industry. We have basetanks, covers, flanges, insulating flanges, bellows flanges, circuit breakers, electric boxes of various sizes, motor housings etc for our esteemed multinational clients in the Electrical, Power and T&D sector.

At Dr. Dinesh & Ramesh Engineers we have developed various parts catering to the cooling fan industry including fan blades, motor body, hub for blade, individual fan blades amongst other parts. We are able to manufacture parts as per the requirement of the customer.
