aluminium extrusion dies for thermal break windows

Electrical Discharge Machining  

Abbreviated as EDM, full name Electrical Discharge Machining.

Properties: It is a mechanical processing equipment, mainly used for EDM.

Application: Widely used in the manufacture of various metal molds and mechanical equipment.

Principle: It is a special processing method that uses the electric erosion effect generated by the pulse discharge between the two electrodes immersed in the working fluid to erode conductive materials, also known as electric discharge machining or electric erosion machining.

Function: Spark processing is mainly used for processing molds and parts with complex-shaped holes and cavities; processing various conductive materials, such as hard alloys and hardened steel; processing deep fine holes, special-shaped holes, deep grooves, narrow Sewing and cutting sheets, etc.; processing various forming tools, templates and thread ring gauges and other tools.

Computer Numerical Control

A CNC milling machine is a milling machine controlled by a digital signal of an electronic meter.

CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar.

Saw Machine

The circular saw band is tensioned on two saw wheels, and the saw wheels drive the saw band to cut. There are two main types of band sawing machines: vertical and horizontal.

The saw frame of the vertical band sawing machine is set vertically, and the workpiece moves during cutting, which is used to cut the curved contour of the sheet and formed parts. The saw band can also be replaced with a file chain or abrasive belt for repairing or grinding.

The saw frame of the horizontal band sawing machine is arranged horizontally or obliquely, and is fed in the vertical direction or in the direction of swinging around a point. The saw band is generally twisted by 40° to keep the saw teeth perpendicular to the workpiece.

Horizontal type is divided into scissors type, double column, single column type band sawing machine; according to the use situation, it can be divided into manual type (economic type, manual feeding and manual cutting of materials), automatic type; according to the automation program using the controller, it can be divided into manual type ( Semi-automatic manual feeding) Fully automatic type (automatic feeding and automatic cutting)

Aluminum resource distribution

The world's bauxite resources are relatively abundant. According to 2015 data from the United States Geological Survey, the world's bauxite resources are 55-75 billion tons. The world's proven reserves of bauxite are approximately 28 billion, mainly distributed in Africa (32%), Oceania (23%), South America and the Caribbean (21%), Asia (18%) and other regions (6%) .

From the perspective of country distribution, bauxite is mainly distributed in Guinea, Australia, Brazil, China, Greece, Guyana, India, Indonesia, Jamaica, Kazakhstan, Russia, Suriname, Venezuela, Vietnam and other countries.

Among them, Guinea (proven bauxite reserves of 7.4 billion tons), Australia (proven bauxite reserves of 6.5 billion tons) and Brazil (proven bauxite reserves of 2.6 billion tons) account for approximately 60% of the world's total proven bauxite reserves.
