aluminium extrusion mold for LED lighting profiles

What are the specifications of aluminum profiles?

The materials for manufacturing aluminum are: 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000 and other series.

The classification of aluminum is: plate, strip, platinum, profile, bar, pipe, etc.

The aluminum rod materials of extruded aluminum profiles generally include: 1000 series, 2000 series, 3000 series, 5000 series, 6000 series, 7000 series, etc. The commonly used raw materials are 2 series and 6 series. The extruded material is also different according to the application.

The specifications and dimensions of aluminum door and window profiles are mainly marked by the height dimension of the profile section (the thickness dimension of the door and window frame used in aluminum alloy doors and windows), and constitute a dimension series. Aluminum door and window profiles mainly include 40, 45, 50, 55, 60, 65, 70, 80, 90, 100mm and other size series. Among them, the size series for aluminum alloy windows is small, and the size series for aluminum alloy doors is too large.

Divided according to alloy composition: aluminum doors and windows are marked with the same size series, not necessarily the cross-sectional shape and size of aluminum doors and windows profiles are the same. The cross-sectional shapes and sizes of aluminum alloy door and window profiles of the same size series are quite complicated. It must be analyzed and treated in detail according to the drawing.

Aluminum door and window profiles are divided into solid profiles and hollow profiles according to the cross-sectional shape, and the application of hollow profiles is relatively large. The wall thickness of aluminum door and window profiles is not less than 1.4mm for aluminum alloy windows, and not less than 2mm for aluminum alloy doors. The length dimensions of aluminum door and window profiles are divided into three types: fixed length, double length and indefinite length. The length of the fixed length is generally not more than 6m, and the length of the variable length is not less than 1m.

Aluminum points: 1 series, 2 series, 3 series, 4 series, 5 series, 6 series, 7 series. 2014 applied to occasions requiring high strength and hardness (including high temperature). Aircraft heavy, forgings, thick plates and extruded materials, wheels and structural elements, multi-stage rocket first-stage fuel tanks and spacecraft parts, truck frames and suspension system parts.

Factors That Affecting the Price of Aluminum Extrusion Dies

The types of aluminum profile extrusion dies are different, and the design of the die structure combination is different, so the price is also different.

1.Structure

Aluminum profile molds are divided into flat molds and split molds, and there is also an integral mold for the extrusion production of seamless pipes, which are relatively rare. Today we will focus on the flat die and the split die. The flat die is used for profiles without a cavity, and the split die is used for profiles with a cavity. The split mold is a combination of upper and lower molds, so the price is more expensive.

2.Size

The larger the profile mold is, the larger the profile mold is. The material of the aluminum profile mold is generally H13 steel, and the larger the mold, the higher the price. That is to say, the larger the cross-section, the higher the price of the aluminum profile mold

3.Cross section complexity

The cross-section of aluminum profiles ranges from simple square tubes or round tubes to complex radiators or multi-cavity profiles. Although split molds are used, the development costs of the molds are different. The more complex the cross-section, the higher the cost of the mold.

Aluminium Extrusion Working Principle:

During extrusion, under the strong extrusion force, the ingot is divided into several strands of metal by the knife (bridge part) of the mold and flows into the mold welding chamber. Under the conditions of high temperature, high pressure and high vacuum, the metal is re-welded and flows from the die hole to the needle. It flows out from the formed gap to form a hollow product of the required shape and size. The number of welds in the product is the same as the number of strands of metal flow.

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.
