In the automotive industry, lightweight has become a key technology to improve fuel efficiency, reduce emissions, and enhance vehicle performance. In this pursuit, lightweight aluminum technology plays a vital role. This paper will deeply understand how powder metallurgy PM lightweight aluminum technology becomes the key technology to achieve lightweight automobile manufacturing and bring revolutionary changes to the automobile industry.

The necessity of lightweight cars

With the increasing awareness of environmental protection and the increasing requirements for energy efficiency in the automotive industry, lightweight has become a top priority in automotive manufacturing. Reducing vehicle weight improves fuel efficiency and reduces exhaust emissions while enhancing suspension, handling, and safety. However, how to reduce weight while maintaining structural strength and safety remains a challenge.


JH MIM is a one-stop solution for powder metallurgy PM lightweight technology. We support automotive aluminum lightweight manufacturers to produce reinvented technologies to optimize use.


What advantages of PM lightweight aluminum technology

PM lightweight aluminium technology with its unique advantages is the ideal choice to achieve the goal of lightweight. This process takes advantage of the excellent properties of aluminum alloy, molten aluminum alloy is injected into a mold by high pressure, and quickly cooled and solidified to create parts with complex shapes.


Automotive lightweight aluminum alloy material

Aluminum automotive panels can be classified into 5XXX series, 6XXX series, and 7XXX series from the alloy composition. 5754, 5182, 5023 for inner covering parts and structures; 6016, 6014, 6022, 6111 for external cover parts; 7075 Structural parts for thermoforming.

In order to meet the demand for new energy vehicles for high-performance aluminum alloy sheets, the Aluminium Materials Application Research Institute has carried out a correlation study on the composition – process – metal microstructure – basic properties and application properties of 5XXX, 6XXX, 7XXX series aluminum alloy automotive sheets. Through these studies, combined with industrial production, it has realized the large-scale application of 6014 and 6016 aluminum alloy plates for the outer plate of the overlay, 5182 and 5754 aluminum alloy plates for the inner plate of the overlay or structural parts, and 7075 aluminum alloy plates for hot forming.

Compared with the traditional casting process, PM lightweight aluminum technology has the following significant advantages:

  1. Lightweight design: Aluminum alloy has low density, but has excellent strength and stiffness, which can achieve weight reduction while maintaining structural strength.
  2. Complex shapes: The PM lightweight aluminum process enables the production of complex, detailed parts that meet the diverse needs of modern automotive design.
  3. Superior surface quality: The surface of the aluminum parts is smooth and flat, reducing the need for subsequent processing and improving production efficiency.
  4. Fast production cycle: PM lightweight aluminum process has a short production cycle and ADAPTS to the efficient production needs of the automotive industry.

The application of  aluminum in automotive industry

The applications in automobile manufacturing are extensive and diverse. aluminum products are found everywhere, from engine parts to body structures, from suspension to transmission components. For example, engine components such as the engine cylinder head, undershell, and transmission housing can be manufactured with lightweight aluminum, reducing the weight of the vehicle and improving fuel efficiency. Chassis components such as suspension arms and steering gearboxes can also be made using PM lightweight aluminum for better suspension performance and handling stability.

Can you sign our NDA before we provide sensitive project information?

Yes, this is a routine operation for most companies before making an inquiry.

Do you provide proofing services?

We have metal 3D printing equipment and can provide sample 3D printing.

Why do I need to provide 2D (PDF) and 3D (STEP) drawings during inquiry?

3D drawings allow engineers to better understand the structure of the product, and 2D documents can provide more information, including materials, tolerances, surface treatment, etc. More detailed information is conducive to more accurate quotation by engineers.

How long does it take to get a quote after sending an inquiry?

In the case of detailed inquiry drawings and information, it usually only takes 2-3 days for us to give you a detailed quotation, including product price and mold price.

What preparations need to be made before confirming production?

After confirming the order, we usually take 5-7 days to prepare the DFM report of the product. After confirmation, we spend 25 days to complete the mold, and provide T1 samples to customers for testing in the following 10-15 days.

If there is a problem with the test, we will re-sample it for free based on the feedback and provide a suitable sample.

What is the MOQ?

MIM products MOQ 2000 PCS

CNC products MOQ 2000 PCS

Alu die casting,  MOQ 2000 PCS

PM product MOQ 5000 PCS

JH MIM lead time?

Typically, the lead time for processing and submitting samples is 30 days. However, according to the order quantity and special requirements of customers, we can extend or shorten the delivery cycle accordingly.

How to ensure quality?

1-year product warranty

World-class testing equipment

30+QC Workers

Key sizes 100% checking before shipment


What is the payment method for JH MIM orders?

Usually T/T is used as the payment method

Mold: 50% deposit, 50% payment after confirming the sample.

Bulk production: 30% deposit, 30% see bill of lading Copy, pay 70% balance.
