Custom Aluminum Cylinder Head Design

Our cylinder heads allow air and gasoline into the combustion chamber and cover the cylinders. High-quality aluminum cylinder heads help build enough compression in the chamber for an engine to work.

We manufacture one-cylinder heads for conventional in-line engines, as well as two-cylinder heads for V-engines. If you need, we can also engineer a one-cylinder head for your V-engine. As mentioned, we supply custom aluminum cylinder heads for high-performance, direct injection diesel, gasoline, four-stroke, two-stroke, and other engine types.

Our employees will consider your custom measurements for valve length, lift, and diameter, combustion chamber size, valve angle, camshafts, intake port configurations, the shape of the flame deck, and more.

Aluminium Cylinder Heads Production

Aluminium Cylinder Heads Production

HM constantly improves factory conditions and capabilities. We produce 5 million parts per year using 100 sets of CNC machinery and 10 sets of automatic die casting equipment.

You may also request CNC porting, which is a machining process that applies CNC techniques to a standard cast cylinder head. This improves efficiency and precision. Die casting alone may not be as precise, and CNC milling is not as fast. CNC porting enhances production output.

Our CNC machines can precisely shape the combustion chamber or runner, with a tolerance of 0.002um. Simply contact us, and our staff will advise the best manufacturing option for you.

Aluminium Cylinder Heads Application

Aluminium cylinder heads are used in all sorts of engine types and vehicles. This includes high-performance racing cars, trucks, city vehicles, motorcycles, and more. HM can manufacture cylinder heads for specific purposes and brands, such as V8 Chevy and V6 Mustang engines.

Bring your custom idea to life with HM aluminum cylinder heads.

High-Performance Cylinder Heads

High-performance aluminum cylinder heads are lightweight but strong enough to raise horsepower. Aluminum heads dissipate heat faster, improving the durability of your engine. Also, it will draw in a dense, cooler air-fuel mixture to the combustion chamber, which increases power output.

Wide Selection of Alloys

Many businesses in the automotive industry choose aluminum cylinder heads due to the material’s high strength-to-weight ratio. HM manufactures aluminum cylinder heads using different aluminum alloys to suit your application:

  • Acd12
  • A380
  • ZLD104
  • Al 6061
  • Al 6082
  • Al 6063
  • Al 075

You can also request aluminum anodizing, sandblasting, chrome plating, zinc plating, powder coating, painting any color, and laser engraving.

Quality Checking
What are the Upgrades and Modifications of an Aluminum Cylinder Head?

An aluminum cylinder head’s lower face, which mates with the block, can wear and warp over time.

Decking, resurfacing, or head skimming is a process that is used to reinstate a flat surface on its head.

Porting is the process of modifying the engine’s ports, typically by polishing the walls perfectly smoothly.

The gas flow through the head will be improve as a result of this.

Polishing takes time but can be done at home with simple tools.

The camshaft is located in the head of an over-head cam engine, the most common engine type.

Inline engines use a single aluminum cylinder head, whereas flat and W engines use various cylinder heads.

What Materials are Used to Make an Aluminum Cylinder Head?

Cast iron or cast aluminum are used to make cylinder heads.

Cast aluminum is more costly to make, but it saves weight and dissipates heat more effectively than cast iron.

Almost all gasoline engines in production use an aluminum head, whereas cast iron is still widely used.

An aluminum cylinder head’s interior is a sophisticated system of oil galleries and cooling system entry.

The lost-foam casting approach is generally used to form these inner cavities in heads.

An aluminum cylinder head is made of durable metallic materials and light metals.

What Components Does an Aluminum Cylinder Head Protect For?

The nozzle gear and engine components are also housed within the head.

Complex coolant and oil passageways are located inside the cylinder head.

The top end of the engine is comprised of the head and the components it houses.

The engine’s mechanical control center is the head, in many ways.

It is where the intake, exhaust, ignition, and fuel systems all come together.

What are the Advantages of an Aluminum Cylinder Head?

Here are the advantages offered:

  • Give ways through which air and exhaust gases enter and exit the combustion chamber.
  • Heat is dissipated more quickly in aluminium cylinder heads.
  • This enables higher compression ratios while reducing the risk of detonation.
  • Provides a fresher air or fuel combination to the exhaust gases.
  • Low pressure is compact and has the potential to generate more power.
  • Extremely resistant to corrosion and can be easily repaired.
  • Its softness makes welding and machining easier.
  • It is secured to the motor frame by four hydraulically fastened bolts.
  • Increases the efficiency of engine operation of vehicles.
  • Houses the gas paths and works as a mounting point for the nozzle vents.
  • Allows for the experimental modification of the fuel injection system.
  • Highly cost effective and functions well as per requirements.
