Miniature Aluminum Extrusion

Weihua technology (custom aluminum extrusion companies) has more than 10 years of cold stamping/drawing/hot forging experience in aluminum alloy industry, focusing on the production and processing of aluminum die making and punching/drawing/forging/CNC, aluminum extrusion die, 3C and consumer electronics, etc.Welcome to consult extruded aluminum enclosures electronics.

How to optimize the aluminum extrusion process of mobile phone case and reduce the technical waste.

There are many aspects that affect the extrusion process of technical wastes, which covers the whole extrusion production process.Mainly including: ingot quality, process temperature, extrusion speed, extrusion tools, molds, loading and unloading, aging heat treatment, etc.

In addition to the development of advanced, scientific production technology, but also the correct strict implementation of operating procedures, improve the degree of skilled workers and sense of responsibility.

Reduce the variety of production per shift as far as possible, the best arrangement is only 3 ~ 5 varieties per shift, improve the production of a single set of mold on the machine.The more kinds of mold aluminum the more, the lower yield.

The impact of the mold on the yield mainly has two aspects: the new mold test mold and the production mold use the more times of test mold, the more mold aluminum taken away, the lower yield.

So we must improve the mold design and production level.Production mold to careful maintenance, reasonable nitriding, timely maintenance.Ensure that each machine qualified rate is high.Good molding, high durability.If each shift due to mold maintenance unqualified, resulting in 3 ~ 4 varieties on the machine production failure, the yield will be reduced by at least one percentage point.

The extrusion tools include: extrusion barrel, extrusion rod, extrusion pad, die pad, etc.The main guarantee extrusion barrel, rod, mold three concentric.

Secondly, reasonable maintenance of the extrusion cylinder, correct heating, ensure the cylinder end flat.Eliminate all kinds of extrusion tube and mold bad match phenomenon.

Clean the residual aluminum on the inner wall of the extrusion tube regularly, check whether there is any damage to the inner hole wall, and use the die pad correctly to improve the support strength of the die.

Extrusion temperature, extrusion speed and cooling have a great impact on the product structure, mechanical properties, surface quality, and yield.

In addition, the three will affect the length of the product, the casting bar temperature is high, the extrusion speed is fast, the cooling speed is low, will make the product after the extrusion of the length of the increase, the growth rate can reach 0.5% ~ 1%, also affect the phone shell aluminum profile linear density, so a stable process can improve the yield.

Improve the subsequent process of extrusion to avoid technical waste.Extrusion of the subsequent process of transport, mainly pay attention to the phone shell aluminum profile scratch.
