Quality Control
For over two decades, Dhwani Engineering has been a trusted name in the die casting industry, known for delivering precision-crafted components with consistent quality. We source only premium-grade raw materials such as aluminum, zinc, and steel from trusted suppliers to ensure the integrity of our products from the very beginning.
Our dedicated Quality Control team rigorously monitors each stage of the manufacturing process. Every casting is inspected for key parameters — including dimensional accuracy, structural integrity, surface finish, and mechanical strength — to ensure it meets both international standards and our own elevated internal benchmarks.
- Corrosion resistance.
- Performance.
- Dimensional accuracy.
- Porosity and brittleness
- Various physical and chemical properties
To maintain this high standard, we utilize advanced testing equipment such as:
Spectrometers for precise chemical composition analysis
Coordinate Measuring Machines (CMMs) for dimensional accuracy
And other specialized instruments for in-depth product verification
Our strict quality protocols ensure that every component we deliver is not only compliant with global industry standards but also built to perform with exceptional reliability in real-world applications.

Frequently Asked Questions
What is gravity die casting?
Gravity die casting involves pouring the molten metal into the casting mould. Usually, the metal is poured manually with a ladle. At DE, we have special tilting machines to ensure precise speed and direction while pouring metal into the mould. The molten mould fills the mould with the help of gravity and is left to solidify. After the casting is set, it is removed from the mould and sent for removing shard edges and other treatment.
What is high pressure die casting?
High pressure die casting is more complex process that is performed using a securely locked die cavity. Molten metal is injected into the cavity with high speed and pressure. The high pressure injection ensures that any gas present in the mould is released, and it also feeds additional metal as the metal shrinks when solidifying.
What is hot chamber die casting?
In Hot-chamber die casting process molten metal is injected through the cavity of a pre-shaped mold using pressure. The defining characteristic of hot-chamber die casting is that metal is heated inside the casting machine rather than a separate machine or furnace.
Do you export your products?
Yes, we are exporting to Germany, UK directly. Also we are exporting to EOU units in India.
Which types of customers to you supplying?
