hollow dies for LED lighting aluminium extrusion

The Difference Between Solid Die and Hollow Die

Solid Die

The solid die is relatively simple, as long as the split hole is designed, the aluminum handle is squeezed out of the flat flag hole to form a cross section after mixing.

Like aluminum flat strips, aluminum rods, some special-shaped materials, etc.

Hollow Die

Hollow dies are generally combined by two combined molds, so that the cavity can be formed by splitting the flow through the working belt during extrusion, such as aluminum shells and round tubes.

For ordinary extrusion dies, to produce hollow profiles, a splitter die must be used, which consists of an upper die and a lower die. The upper die is generally used to guide flow and position the hollow part of the hollow profile. The lower mold is the outer surface working belt and empty knife.

Most of the non-hollow profiles use solid dies. Generally speaking, there is only one mold including diversion and working belts. Of course, there are special cases. Here we only explain the general production conditions.

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.

Why do LED explosion-proof lights use aluminum alloy?

What are LED explosion-proof lights? Why do LED explosion-proof lights choose to use aluminum alloy? What are the benefits of using aluminum alloy LED explosion-proof lights?

LED explosion-proof lamps are lamps used in dangerous places where flammable gases and dust exist. They can prevent arcs, sparks and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment, thereby meeting explosion-proof requirements.

Why choose aluminum alloy for LED explosion-proof lights? What are the benefits and advantages?

1. Aluminum alloy conducts heat quickly, and the lamp generates a lot of heat. If there is no metal with fast thermal conductivity, the lamp may burn out because the heat cannot be dissipated. Just like Apple phones use aluminum alloy casings, but not just because of thermal conductivity.

2. Aluminum alloy is easy to form and has strong impact resistance. This impact resistance does not mean that the hardness is hard, but because it is relatively soft, it can effectively relieve the impact when it is impacted.
