Die casting machine for aluminum road stud mould is cold casting machine.
The material of aluminum die-casting molds is relatively important.
For example, AISI O1 steel and gray cast iron are used.
These materials have good high-temperature resistance.
Meanwhile, the gating system and exhaust design are also very important to ensure the flow of molten aluminum and reduce porosity.
The shrinkage factor of the mold also needs to be considered to avoid dimensional issues.
Furthermore, Aluminum Road Stud is a device used for permanent road division and marking, and is usually made of durable aluminium alloy.
It is a traffic facility used to enhance road safety, mainly made of high-strength aluminum alloy.
With reflective strips (such as frosted glass or prism reflectors) on the surface, which improves visibility at night and in bad weather by reflecting vehicle lights.
Aluminum Road Stud mould
There are several factors to consider when choosing a die casting machine for aluminum road stud mould, including injection energy, chamber capacity, clamping force, and mold installation size.
In the production of aluminium road markings, a cold chamber die casting machine is often used because the aluminium has a high melting point and needs to be injected under high pressure.
Make aluminum road stud mould
The fabrication of an aluminum road stud mold involves multiple steps and material selection.
Here are the details about aluminum road nail molds:
Mold material selection
Aluminum alloy
Although aluminum alloy has the characteristics of light weight, good thermal conductivity and strong corrosion resistance.
Its strength is low and it cannot withstand the effects of high temperature and pressure.
Therefore, aluminum alloy molds are suitable for low-pressure, low-temperature, low-speed hot forging and hot extrusion processing.
Tungsten carbide
Steel is especially suitable for use in high temperature and high pressure environments due to its high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent properties.
Tungsten steel retains a high hardness at a temperature of 500°C and a high hardness at 1000°C.
Cold work steel
For aluminum stamping dies, it is recommended to use cold work steels, such as powder steels such as V10, V40, V4, etc., as well as materials such as Cr12MoV, SKD11, D2, DC53, GOA, etc.
These materials have excellent machinability, good thermal stability, good polishing properties and sufficient surface hardness and wear resistance.
H13 Steel
The material suitable for aluminum extrusion die should have basic properties.
Such as high yield strength and hardness at high temperatures, excellent fracture toughness, and high tempering resistance.
H13 steel performs well in high-temperature and high-pressure environments.
And is able to withstand the thermal fatigue caused by high temperature action and repeated heating and cooling.
Mold manufacturing process
Cast aluminum road studs usually use a permanent mold casting process.
First, the upper and lower dies are combined, and then the liquid aluminum is poured into the mold.
And after cooling, the aluminum road studs are obtained.
The surface treatment of the mold is also important, and it is often anodized to enhance corrosion resistance and hardness.
Application of molds
Aluminum road stud molds can be used to produce products with complex shapes
Such as rotary molds, which are capable of producing complex polyhedral shapes.
In practical applications, aluminum road nail molds are not only used for casting aluminum products.
But also for casting other metals such as copper.
Mold maintenance and maintenance
Aluminum molds require regular maintenance to maintain their accuracy and longevity.
They are lighter than steel molds, but they require regular inspection and maintenance.
Aluminum Road Stud mould material——H13 steel
H13 tool steel has excellent application performance in aluminum molds, and its performance characteristics and application fields are as follows:
High hardenability and resistance to hot cracking
H13 die steel has extremely high hardenability and is able to withstand long-term operation at high temperatures without breaking and deformation.
This characteristic makes it excellent in high-temperature and high-pressure environments such as aluminum extrusion and aluminum die-casting.
Abrasion resistance and heat fatigue resistance
H13 die steel has good wear resistance and can maintain a long service life even under high load and high friction conditions.
In addition, it has excellent thermal fatigue resistance and is able to remain stable in alternating heating and cooling cycles.
High strength and hardness
The hardness of H13 die steel can reach 55HRC after heat treatment, which has high strength and hardness, so that it can still maintain good working performance at high temperatures.
Oxidation and corrosion resistance
The role of aluminum in steel significantly improves the oxidation resistance and corrosion resistance of H13 die steel.
For example, the addition of 6% aluminum can make steel oxidation resistant below 980°C, and even better when used with chromium.
Excellent comprehensive mechanical properties
H13 die steel not only has high hardness and strength, but also has good toughness.
So that it can maintain excellent performance in high temperature, high pressure, high strength and high wear environment.
Wide range of applications
H13 die steel is widely used in the manufacture of die-casting molds for aluminum, zinc, and copper alloys, as well as plastic molds and other high-wear-resistant, high-strength tools.
Especially in the fields of aluminum extrusion molds, aluminum die-casting molds.
H13 mold steel prolongs the service life of the mold and reduces the risk of damage due to its excellent hardness and wear resistance, thermal fatigue resistance and good toughness.
Die casting machine for Road Stud mould
Choosing the right die casting machine for aluminum road studs requires a combination of factors to ensure that the equipment can meet production needs and ensure product quality.
Here are the detailed analysis and recommendations:
Product design requirements
The size, shape, material and quantity of aluminum road studs are an important basis for choosing a die-casting machine.
Aluminum road nails usually require high precision, high stability, and high clamping force to ensure the dimensional accuracy and surface finish of the product.
Production capacity and efficiency
Depending on the production quantity and cycle demand of aluminum road studs, multiple or high-speed die casting machines can be selected to improve production efficiency.
For high-volume production, the use of high-speed die casting machines can significantly increase throughput.
Ease of operation and maintenance costs
Choosing a die casting machine that is easy to operate and low maintenance can reduce production costs and improve market competitiveness.
Die Casting Machine Type
Aluminum road nails are usually used in cold chamber die casting machines because cold chamber die casting machines are suitable for high melting point alloys.
Such as aluminum and can provide higher compressive strength and product integrity.
Clamping force and mold size
The clamping force of the aluminum road nail should be greater than the theoretically calculated expansion force to prevent the splashing of the molten aluminum.
And ensure the locking of the parting surface of the mold, so as to ensure the dimensional accuracy of the casting.
Degree of automation
Choosing a die casting machine with a high degree of automation can reduce manual intervention, increase output and reduce labor costs.
