Quality Assurance

Quality-centered, continuous improvement, customer satisfaction.

In 2018, we established the IATF16949: 2016 quality management system and have developed standard documents such as APQP, PFMEA, CP, and PPAP. For each process, we have also established corresponding technical standard documents, including Standard Operating Procedures (SOPs) and Standard Inspection Procedures (SIPs).

Driven by the pursuit of “zero-defect quality,” we maintain stringent inspection standards—from incoming materials and manufacturing processes to finished products and shipment—and continuously strengthen and enhance our process quality levels.

The relevant products are subject to SPC and MSA management, and a 100% visual inspection process has been added—all to ensure that every product is meticulously crafted and every customer is thoroughly served.

Aluminum alloy die casting industry prospects

Aluminum ADC12 for aluminum alloy die-casting. Aluminum alloy die-casting products are mainly used in electronics, automobiles, motors, home appliances and some communication industries. Some high-quality aluminum alloy products with high performance, cover accuracy and high toughness are also used in large aircraft and ships. and other demanding industries. Die casting is a kind of precision scoring casting method. The dimensional tolerances of die castings cast by die casting are very small and the surface accuracy is very high. In most cases, die castings can be assembled and applied without turning. Threaded parts Can also be cast directly. Compared to other casting techniques for copper, die casting has a flatter surface and higher dimensional consistency.

Aluminum alloy die casting process

Aluminum alloy die-casting is a kind of pressure-casting parts. It is a pressure-casting mechanical die-casting machine equipped with a casting mold. The heated liquid aluminum or aluminum alloy is poured into the feed port of the die-casting machine. Aluminum parts or aluminum alloy parts with limited shape and size, such parts are usually called aluminum alloy die castings. There are four fires in the casting process of aluminum alloy die castings: annealing, normalizing, quenching and tempering. In the die casting process, the relationship between quenching and tempering is very close, and both are indispensable. The casting process of aluminum alloy die castings is to fill the molten metal into the cavity of the mold at low speed or high speed first, and the mold has a movable cavity surface. The hole shrinkage defect also makes the internal structure of the blank reach the broken grains in the forged state. The comprehensive mechanical properties of the blanks are significantly improved. In addition, the Zhulai blanks produced by this process have a high outer surface finish, and the surface produced by the cold extrusion process or machined has the same metallic luster.

How to solve the cracking on the surface of aluminum alloy die castings?

1. The iron content or silicon content in the aluminum alloy is too high. 2. The content of harmful impurities in the alloy is too high, which reduces the plasticity of the alloy. 3. Aluminum alloy die-casting mold, especially the overall temperature of the mold cavity is too low. 4. Where there are drastic changes in the wall thickness and thickness of the casting, the shrinkage is blocked, and the sharp corners form stress. 5. The mold retention time is too long and the stress is large. the solution: 1. Correctly control the alloy composition. 2. Change the casting structure, increase the angle, change the draft angle, and reduce the wall thickness difference. 3. Change or increase the ejection position, so that the ejection force is uniform.

Reasons and Solutions for Deformation of Aluminum Alloy Die Castings

First analyze why aluminum alloy die castings are deformed? One is the overall or local deformation, and the other is that the geometry of the die casting does not match the drawings. The reasons for this situation are as follows. The structure of the casting is not good and the mold is opened early, which leads to insufficient rigidity of the casting and improper setting of the ejector pin, resulting in uneven force during ejection, improper gate position or too thick gate. It is easy to deform when the gate is removed, the local rough surface of the mold causes a large resistance, the deformation of the product when the product is ejected, and the temperature of the mold is too high, resulting in no solid state of the casting, or excessive force during the ejection, resulting in deformation of the product. For this kind of deformation problem of aluminum alloy die castings, the solution can be considered from the following points, improving the casting structure, reasonably adjusting the mold opening date and pressure holding, reasonably setting the ejection position and the number of ejectors, changing the gate thickness, strengthening the mold Handling, reducing demolding resistance, controlling local mold temperature, and maintaining mold thermal balance.
