Changing Metal Properties With Heat Treatment

Throughout history people have been creating things from different metals. Presumably the discovery of metal was an accident and probably caused inadvertently when a campfire burnt away some low melting point metal bearing ore and left the bewildered ancient with a crude metal lump.

Most likely the first such metal would have been tin as this has the lowest melting point by far of all other common metals. At two hundred and thirty two degrees centigrade the core of the fire would not have to be particularly hot to extract tin unlike iron which needs one thousand five hundred and thirty degrees to melt.

The melting point of metals vary a great amount and as the discovery of tin extraction became more and more understood and easier to achieve, the ancients of Mesopotamia and at the same time China, began looking for other metals. Tin was a useful metal but far too soft to create anything much more than plates, pots and ornaments. The next big step was the discovery of copper with tin deposits and this alloy we know of as bronze.

With a melting point of just under one thousand degrees centigrade, bronze could be fashioned into a much stronger finished product. For the first time metal swords and other weapons could be made as well as intricate jewellery mounted with precious stones.

Today bronze is still a valued alloy. With the addition of less than one per cent phosphor, the alloy can be easy to cast with an exceptionally smooth finish. This tough alloy known as phosphor bronze has a very low coefficient of friction making it ideal and nearly always the preferred metal of ships propellers. It has the additional property of not sparking which makes it ideal for electrical contacts. Screws made of phosphor bronze are used whenever there is the threat of electrical shorting and water.

Any metal can be heated to change its properties and every metal has some unique uses. Heat treatment of steel along with quick but not harsh cooling can toughen the original product. During heating magnetic alignments can be changed and this will also change the properties of the original.

Heat treatment is used to add subsidiary metals creating alloys for very specific uses. There are many types of aluminium die casting alloys for specific purposes and NASA and European as well as Russian space agencies all use the same particular Aluminium alloy for their space craft.

Over thousands of years men have been making things out of pure metals and alloys. The values of all metals can change with the discovery of new uses. For example, when catalytic converters were first discovered in the late 1980s the catalyst used in the exhaust system to convert carbon monoxide into harmless air and water was a mix of palladium and rhodium. Prices of these two metals shot up in value and later when more cars were being produced globally with diesel engines, palladium dropped heavily as Platinum took over.

Die Casting Process

Aluminum Die casting is a fast, cost-effective manufacturing process for production of high volume, net-shaped, tight tolerance metal components. It has the benefit of increased quality and repeatability, often at lower costs compared to other processes.

The die casting process is the injection under high pressure into a steel mould (or tool) of a molten metal alloy, which solidifies rapidly (from milliseconds to a few seconds) to form a net shaped component and is then automatically extracted. The die casting tool will typically produce any number of components from hundreds of thousands to millions, before requiring replacement .

Die Casting Technology

Plastic Molds & Die Casting Technology

Plastic Molds is the widely used tool products in manufacture. Without die injection mould, die casting mold, extrusion tool/mold, deep drawing die and stamping die, factories would be unable to produce plastic parts, alloy die castings, steel plate parts and forgings which are widely used and have a competitive price. In the mass production nowadays, losing high-level molds just means losing high quality products. And molds play an important role to improve production efficiency and reduce production costs. Nowadays, mold manufacturing has become an important part of advanced manufacturing technology.

Material for plastic mold, die casting mold or stamping tools

The material of mould usually is a kind of difficult-to-process material. At present, the domestic mold cavity generally adopt electric spark machining (EDM). However, the production efficiency of electric processing is very low. No matter on the side of development speed or on the aspect of manufacturing quality, it can never meet the requirements of modern mass production.

The occurrence of the high-speed machining technology has opened a new door for mould manufacturing technology. It is the inevitable trend that high-speed machining technology will instead of electric processing to improve the development and quality of mould manufacturing.

The advantages of high-speed machining mould

All of  stamping mold or plastic mold (including injection mould, extrusion die, blowing die, etc.), die casting mold need high strength wear resistant materials to produce some parts in order to improve their service lives (such as all kinds of brand of alloy structural steel, alloy tool steel and stainless steel, etc.). The hardness of these materials is very high after heat treatment. However, this is difficult to do by the method of conventional mechanical processing. For decades, special processing is the best way to deal with this kind of material.

In China, it is still the world of the electric spark machining, and it has been playing an important role in mould manufacturing. Along with the development of the production and upgrade of products, the requirement of production efficiency and manufacturing quality is higher and higher. Then the problems of electric spark machining exposed gradually. Its production efficiency is low and the quality is not stable. The problem of mold has been a key factor to the development speed of new products.
Compared with the electric spark machining, the high-speed machining technology has these main advantages:
1.    Good quality of products
2.    High production efficiency
3.    it can deal with the thin wall parts and the hard parts which have complicated shapes

In recent years, high speed machining technology has widely used in die and mould industry in overseas. According to statistics, there are 85% of mould electric spark forming process has been replaced by a high speed machining in the countries which have highly developed industries. High speed machining has been established the mainstream status in the international mold manufacturing process. Some famous companies which were engaged in electric processing equipment manufacturing originally (such as Company Agie in Switzerland) have already found the development trend of technology. In order to keep up with the market of mold equipment, these companies have taken measures to unite with high speed machine tool manufacturers (such as Mikron in Switzerland).

All of parts that need mold, aluminum die casting need high pressure die casting mold, plastic molding parts needs plastic mold, and mdifferent type of part need their molds for them.

Development prospect of the high-speed machining technology

The high speed machining has a high machining accuracy, and its surface quality is excellent, so the industry application is wide and effective. And it completely conforms to the development direction of mod manufacturing technology. It will be also the main trend in developing countries in future.
