aluminium extrusion dies for casement windows and doors

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 alloy casement windows are a common type of windows made of aluminum alloy materials. The characteristic of this window is that it can be opened horizontally, that is, the sash can be opened inward or outward.

Aluminum alloy casement windows have the following advantages:

1. Lightweight and durable: Aluminum alloy materials are lightweight and high-strength, making the windows strong, durable and not easily deformed.

2. Corrosion resistance: Aluminum alloy has good corrosion resistance and can resist oxidation and corrosion in daily use, extending the service life of windows.

3. Good waterproof performance: Aluminum alloy casement windows adopt a sealed design, which can effectively prevent rainwater from penetrating into the room.

4. Good sound insulation performance: Aluminum alloy casement windows use double-layer or multi-layer glass, which has good sound insulation effect and reduces noise interference.

5. Easy to clean and maintain: The surface of aluminum alloy casement windows is smooth and flat, not easy to accumulate dust, and easy to clean. At the same time, aluminum alloy materials do not need to be painted, reducing maintenance costs.

Aluminum casement windows are widely used in residences, offices, commercial buildings and other places and are a common window choice.
