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.
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.

Quenching Furnace
The quenching furnace is a furnace that heats the workpiece before quenching.
Quenching is to put the workpiece into the furnace and heat it to the quenching temperature above the critical point and keep it for a period of time, then quickly take the workpiece out of the furnace and put it into the quenching liquid (oil or water) for quenching.
The heat source of the furnace can be electricity and fuel, and the temperature can be measured by a thermocouple.
Furnaces using electricity, gas, and liquid fuels can be automatically controlled and regulated by instruments.
Our quenching standard:
After heat treatment for 14 hours, the hardness reaches 50-52 degrees.
Tempering Furnace
The tempering furnace is used for tempering general metal parts in air and quenching, annealing and aging heat treatment for aluminum alloy die-casting parts, pistons, aluminum plates and other light alloy parts.
The shell is welded by steel plate and section steel, and the trolley is welded by section steel and steel plate.
The trolley can reduce heat radiation and convection loss through soft contact with the furnace lining and sand sealing mechanism, and effectively ensure the sealing of the furnace body.
(Our tempering standard: 2 times*10 hours)
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.
