Introduction to H13 mold steel

H13 mold steel is a hot work mold steel with good thermal strength and hot hardness, good wear resistance and fatigue resistance, good thermal creep resistance, and high hardness after heat treatment, which can reach HRC46-50. H13 mold steel has stable chemical composition, excellent impact toughness and high toughness, which can ensure the service life of the mold.

H13 die steel is mainly used to manufacture high-strength hot tools, such as hot extrusion dies, hot forging dies, die-casting dies, hot shear blades, etc. In addition, it can also be used to manufacture large plastic molds, cold stamping molds, etc.

The advantage of H13 mold steel is that it has high heat resistance and wear resistance, as well as good oxidation resistance and thermal fatigue resistance, and can maintain good hardness and wear resistance at high temperatures. However, H13 mold steel has poor welding performance and requires special welding processes.

Application of aluminum profiles in photovoltaic industry

The photovoltaic industry mainly converts solar energy into electrical energy through solar power generation systems, and the application of aluminum profiles in the photovoltaic industry is mainly reflected in the following aspects:

1. Photovoltaic bracket: The photovoltaic bracket is an important part of the photovoltaic power generation system. Its main function is to fix and support the solar panel so that it faces the sun to obtain the maximum amount of solar radiation. Aluminum profiles have the advantages of light weight, high strength, corrosion resistance, and easy installation, so they are widely used in the manufacturing of photovoltaic brackets.

2.Photovoltaic frame: Photovoltaic frame is a structure used to fix and protect solar panels, usually made of aluminum profiles. Aluminum profiles not only provide good mechanical strength, but also provide good anti-oxidation and corrosion resistance, ensuring the service life of the battery panels.

3. Photovoltaic panel packaging: Aluminum profiles can also be used to package photovoltaic panels, which can provide good sealing performance and prevent the panels from being affected by environmental factors.

4. Photovoltaic power station construction: In the construction of photovoltaic power stations, aluminum profiles can be used to make various structures of the power station, such as cable troughs, equipment racks, etc., to improve the stability and safety of the power station.

Generally speaking, the application of aluminum profiles in the photovoltaic industry mainly uses its characteristics such as light weight, high strength, corrosion resistance and easy processing to provide stable and safe structural.

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.

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.
