Best Aluminum Die Casting Manufacturer

Quality Management System Certification

ISO 9001:2015 (CNS 12681:2016) Certification

As a leading manufacturer of high-precision aluminum die-cast components, ALUNEX has been committed to maintaining the highest standards of quality since 1999, when we first achieved ISO 9002:94 certification. Over the years, we have continually enhanced our quality management systems, and today, we proudly hold the ISO 9001:2015 certification, a globally recognized standard for quality management.

Our die-casting quality meets international standards, with 85% of our products exported to markets around the world. We have long-term partnerships with major global companies and have become a trusted supplier of electric vehicle and bicycle components, engine parts, precision optical lenses, and medical device components in leading industrial technology countries such as the United States, Germany, the United Kingdom, Singapore, and Japan.

Casting quality control and inspection

Casting Quality Control

Raw Material Analysis

We use the German-made Spectro Max spectrometer and the Motic Images Plus metallographic microscope to analyze the composition of aluminum ingots and examine their microstructure. These advanced tools allow us to ensure that the materials meet the required specifications. With precise analysis of both the composition and structure of the raw materials, we can guarantee the quality and consistency of the aluminum ingots used in production.

Die-Casting Process Inspection

During the die-casting process, we employ vernier scale and outside micrometer to measure the dimensions and tolerances of the castings, including inner diameter, outer diameter, appearance, and depth. These traditional yet reliable tools are essential for ensuring that each casting meets the specified design requirements, maintaining the high level of precision our customers expect.

Ensuring Product Precision and Quality

Quality Assurance

To guarantee the precision and quality of our products, we use advanced, specialized inspection instruments. These tests ensure that the final products not only meet precise dimensional requirements but also have a flawless appearance, meeting our customers' high standards.

Hardness Testers

We conduct hardness tests based on the specific requirements of the castings. Using Rockwell hardness testers, we measure the hardness of the castings to ensure that the materials possess the necessary strength and durability. These machines provide accurate readings to verify that the product meets performance requirements.

Surface Profiler

To detect surface defects and ensure the smoothness of the product, we use surface roughness testers. This equipment ensures that the surface finish of the castings adheres to the required specifications, meeting both aesthetic and functional standards.

TOYO 3D X-Ray Computed Tomography (CT)

We utilize the Japanese TOYO 3D X-ray CT scanner to perform precise measurements of both the internal and external structures of the castings. This advanced technology helps us identify defects such as sand holes, casting voids, and other quality issues, ensuring the integrity of the product.

JMT250L Optical Detection 2D Image Measurement Instrument

The JMT250L Optical Detection 2D Image Measurement Instrument reliably detects internal and external defects such as porosity, inclusions, shrinkage, cracks, and blowholes. This tool provides automatic defect recognition, ensuring that all critical quality concerns are identified during the inspection process.

ZEISS Coordinate Measuring Machines (CMM)

The ZEISS CMM systems offer reliable and high-precision coordinate measuring technology. We use these machines to perform precise measurements of complex geometries, ensuring that all components meet strict dimensional specifications.

ZEISS Optical 3D Metrology

We also utilize ZEISS Optical 3D Metrology systems to measure key dimensions, angles, and parallelism of the castings. This equipment ensures that each component meets the highest standards of dimensional accuracy and precision.
