High-Quality Aluminum Die Casting Manufacturer with IATF16949 Certification

Provid Professional Die Cast Aluminum Service Since 1995

CEX Aluminum Die Casting

As an aluminum die casting manufacturer with 28 years of experience, we have more than 60 professional die casting engineers and production workers, a 15,000 square meter die casting workshop, and several sets of patented die casting machines.

90% of products are exported to various countries including USA, Canada, Brazil, Argentina, Germany, Italy, France, Switzerland, Japan, and Korea, and are used in different fields such as machinery, outdoor, household, and automotive.

CEX provides one stop service, from in-house tooling, aluminum die casting, post machining, to surface treatment and assembly, the entire process is completed in dedicated production workshops by experienced workers.

All CEX production is managed under the ISO 9001 and IATF 16949 systems, ensuring the consistent and stable delivery of the best quality die cast products.


China Professional Aluminum Die Casting Supplier

CEX has multiple aluminum die casting machines, which can achieve significant production capacity, ensuring our delivery time and stable and continuous supply volume. This is particularly important for parts that are in high annual demand and is what makes us a trusted aluminum die casting supplier.

CEX has developed patented die casting machines, which can effectively solve the defects of the conventional die casting process, eliminate the problems of internal porosity and shrinkage, and provide aluminum die castings with higher density, strength, pressure resistance, and sealing performance.

We can establish dedicated production lines for long-term cooperative customers with large procurement volumes. We could produce multiple sets of moulds, and use multiple die casting machines, effectively ensuring the best service for important customers.

You only need to bear the cost of one set of moulds when developing the product. Our company will bear the cost of post mould maintenance and repair, as well as the cost of reopening the mould after reaching its lifespan, and adding one set of mould to ensure the production capacity.

Our MOQ for the first batch of aluminum die castings is generally 1000 pieces. For products with complex structures and large weights, the MOQ can be reduced to 300-500 pieces, depending on the situation. Depend on different die casting processes, our daily output of a single die casting machine ranges from 900 to 1600 pieces.

Superior Quality Castings Capability Set Us Apart

T6 Heat Treatment

To further improve mechanical properties

Higher Strength

50% higher than conventional die casting


Could be welded to any aluminum profile

High Pressure Resistance

With high sealing performance

In-House Mould

We can design the right number of cavities, taking into account the volume of purchases and the structure of the part. A higher number of cavities is beneficial for high-volume deliveries but brings with it an increase in first input costs. We will weigh up the options and help our customers to determine the most suitable solution.

We can guarantee the quality of the mould and the delivery time. The quality of the mould is a key factor in ensuring the quality of the product.

Our mould prices are all ex-factory and competitive, helping our customers to reduce the initial investment in their projects.

Customers don’t have to worry about the lifespan of the mould. We can carry out regular mould repairs and maintenance, and develop multiple sets of moulds free of charge for long-term customers, who only need to bear the cost of the initial set of mould. For projects with a large annual production volume, multiple sets of mould will ensure that we continue to produce high-quality products from a stable angle.

Secondary Machining

For precision and complex shaped parts, secondary processing is required based on die casting blanks to achieve specific structures, surface finishes, strict tolerances, and meet drawing requirements.

CEX is equipped with a professional CNC machining workshop. The secondary processing we offer includes: cutting, drilling, tapping, polishing, CNC machining, etc. Capable of delivering various types of aluminum alloy parts that are required with high precision and complex shapes.

The specific content of secondary processing can be found in the internal chain.

Surface Finish

Decorative surfaces can be treated with painting, chrome plating, phosphating, electroplating, powder spraying, and surface passivation.

To prevent environmental corrosion, anodizing and spraying can be used. It should be noted that aluminum alloy die casting parts can only be anodized in black while spraying can be done in multiple colors.

Spray coating: used for decoration, protection, signage, etc., and can hide small surface defects when applied.

Electroplating: make die castings beautiful, and improve density and corrosion resistance. Castings tobe  electroplated must not have casting defects.

Electrostatic spraying: to achieve a beautiful and smooth surface for die castings and improve corrosion resistance.

High Strength T6 Treated Aluminum Die Castings


Mechanical Properties:

  • Yield Strength: 220-240Mpa
  • Tensile Strength: 260-300Mpa
  • Hardness: 80-90Hb
  • Density: 2.72g/cm³
  • Elongation: 4.5-6%

In addition to conventional die castings, CEX can provide high strength, high density, high-pressure resistance, and weldable quality die castings based on our own R&D capabilities and patented equipment.

Conventional aluminum die casting defects have led to difficulties in obtaining the high-quality die castings. This makes us a superior supplier of aluminium die casting parts.

Our high-quality die castings eliminate the internal porosity and achieve a highly dense internal structure.
