Aliuminium extrusion mold for door and window profiles

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.

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.

Wire Electrical Discharge Machining

It belongs to the category of electric processing.

When the couple of the former Soviet Union Lazalianke studied the phenomenon and cause of the damage of the switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark can make the local metal melt, oxidize and be corroded, thus creating And invented the electric discharge machining method.

The wire cutting machine was also invented in the former Soviet Union in 1960, and our country was the first country to use it in industrial production.

EDM wire cutting machine can be divided into reciprocating type:

High Speed Wire cut Electrical Discharge Machining

Low Speed one-way walk Wire cut Electrical Discharge Machining

Vertical Wire Electrical Discharge Machining machine tool With Rotation Wire.

It can also be divided into single column cross table type and double column type (commonly known as gantry type) according to the form of workbench.

Structure of Aluminium Extrusion -Hollow Mold and Solid Mold

Aluminum profile extrusion dies can be divided into solid dies and hollow dies according to the shape of the extrusion section, and hollow dies can be divided into single-hole dies and multi-hole dies.

Hollow mold: It consists of two parts, the upper mold and the lower mold.

The general function of the upper mold is to guide the flow and position the hollow part of the hollow profile.

The lower mold is the outer surface working belt and empty knife.

Solid mold: Only one piece of mold including flow guide and working belt.
