Gravity Die Casting Manufacturer for Automotive & Hydraulic Parts
When your parts need better dimensional accuracy and stronger mechanical properties than sand casting can offer, gravity die casting is usually the right answer. At Mahati Mecatronics, we produce medium to high-volume components for automotive and hydraulic applications, using reusable metal moulds instead of sand.The result is a casting that is more consistent from part to part, with a cleaner surface finish and fewer surprises once it reaches your machining line.
What Is Gravity Die Casting?
It is a process where molten metal is poured, under gravity, not pressure, into a reusable metal mould known as a die. Because the die is reused again and again, parts come out far more consistent than they would from a one-time sand mould, which is exactly why this process is preferred for medium to high-volume runs.
Gravity Die Casting
- Metal is poured by gravity
- Best for medium volumes
- Handles thicker sections well
- Lower tooling cost
Pressure Die Casting?
- Metal is injected at high pressure
- Best for very high volumes
- Better for thin-walled, complex parts
- Higher tooling cost
Where This Process Fits Best
Automotive Components
Brackets, housings, structural parts
Hydraulic Components
Valve housings and fluid power components
Housings & Covers
Parts requiring high dimensional accuracy
General Engineering
Components under load or with repeat demand
What You Gain with Gravity Die Casting
A reusable metal mould brings more control than sand casting, without the tooling cost of pressure die casting.
| Benefit | What It Means for You | Why It Matters |
|---|---|---|
| Better accuracy than sand | A reusable metal mould gives the same shape every pour | Less machining allowance and fewer surprises on your line |
| Cleaner surface finish | Smoother castings straight from the mould | Saves time on cleaning and finishing |
| Stronger, denser parts | Metal cools faster in a metal mould, so the grain is finer | Better strength for parts that work under load |
| Handles thicker sections | Solid, chunky geometries cast well | Ideal for housings, bodies and structural parts |
| Lower tooling cost | Metal moulds cost less than pressure die casting tools | A sensible choice for medium volumes |
| Part-to-part consistency | Pour after pour, dimensions stay steady | Smooth, predictable supply for your assembly |
| Reusable moulds | One mould serves thousands of castings | Lower cost per part than one-time sand moulds |
Our Process
Die Design
Built around your exact part geometry and expected production volume.
Preheating
The die is brought to the right temperature before every pour.
Pouring & Cooling
Metal is poured and allowed to solidify under controlled conditions.
Ejection & Finishing
Parts are removed, trimmed, and inspected before dispatch.
Quality Inspection
Every batch is inspected for dimensions and defects.
Dispatch
Approved parts are packed securely and shipped on time.
Checked at Every Step, Signed Off Before Dispatch
We would rather find a problem in our own shop than have you find it on your machining line.

Frequently Asked Questions
What is gravity die casting process?
Molten metal is poured by gravity into a reusable metal mould, producing parts with better mechanical properties than sand casting.
How is this different from pressure die casting?
This process pours metal for medium volumes and thicker sections. Pressure die casting injects metal at high pressure for high volumes and thin walls.
What materials are used in this process?
Aluminium alloys are the most common, chosen for their strength-to-weight ratio and dimensional stability.
What are the main advantages of this method?
Better dimensional accuracy, stronger mechanical properties, a smoother surface finish, and reusable tooling compared to sand casting.
How much does the tooling cost?
It depends on part size, complexity, and expected production volume. Share your drawing with us for a firm quote.
What is the minimum order quantity?
It varies by part, but this process is generally best suited to medium-to-high volume programs rather than one-off prototypes.
Which industries use this casting process?
Automotive and hydraulic component manufacturers are the biggest users, alongside general engineering applications.
What kind of surface finish can I expect?
It is typically smoother and more consistent than sand casting, which often reduces the amount of secondary finishing needed.
