Since molds are exposed to high temperatures and pressure, they may wear out or deform over time. Regular maintenance extends the mold’s life, reduces production errors, and lowers costs. Repair processes make damaged molds reusable, reducing costs and extending their lifespan.
Mold Cleaning:
Mold cleaning should be performed after production cycles are completed or a specific production volume is reached. Aluminum particles and dirt that accumulate during production can reduce the mold’s performance. Methods such as air pressure, brushing, or chemical cleaning ensure sensitive and effective cleaning without damaging the mold’s surface.
Cooling Channels Maintenance:
Cooling channels ensure that heat is properly distributed during production. Blockages or damages can result in improper cooling of the aluminum and a decline in quality. These channels should be regularly inspected, and blockages should be cleaned with suitable equipment and solvents.
Lubrication and Use of Lubricants:
Regular lubrication of the mold’s moving parts prevents wear and extends the mold’s life, reducing friction. Proper lubricants prevent the metal from sticking to the mold. This process should be repeated periodically depending on production frequency.
Regular Inspections and Examination:
Molds may develop wear or micro-cracks during production, so regular inspections are crucial. Visible damage should be checked, and detailed areas should be examined under a microscope. If wear or cracks are detected, repairs should be made.
Wear and Surface Repair:
Molds that are in constant contact with aluminum during production may experience wear, especially in areas exposed to high temperatures. Wear is addressed with grinding or polishing processes, restoring the mold to its original form. If necessary, surface coatings are renewed.
Crack and Damage Repair:
Molds may develop cracks due to continuous thermal expansion and impacts, which can reduce wheel production quality. Cracks are filled with specialized welding techniques, and the mold is restored to its original condition through surface processing methods.
Cooling Channel Repair:
If cooling channels are blocked or damaged, improper heat distribution can affect production quality. Blocked channels are cleaned with special tools, damaged channels are repaired, and new channels are added as needed to improve the system.
Surface Coating Renewal:
Surface coatings enhance the mold’s wear resistance and prevent aluminum from sticking to the mold. However, these coatings may wear out over time. The coatings are stripped, the surface is cleaned, and it is recoated with the appropriate material. This process is carried out according to the mold’s production process and casting conditions.
The main casting technologies used in aluminum wheel production are Low Pressure Die Casting (LPDC) and High Pressure Die Casting (HPDC) methods. LPDC is a method in which molten aluminum is injected into the mold under low pressure. This process provides controlled filling and leads to fewer air voids within the wheel structure. HPDC occurs by injecting molten aluminum into the mold rapidly under high pressure, making it suitable for mass production and enabling the production of a large number of wheels in a short time.
Low Pressure Die Casting (LPDC) is a casting method where molten aluminum is injected into the mold under low pressure. This process results in fewer air voids and defects in the wheel’s internal structure. LPDC’s advantages include high structural durability, a quality surface, and detailed aesthetics. However, the production process is slower, making it ideal for producing high-quality and durable wheels, though less suitable for mass production. It is commonly used for commercial vehicles, sports cars, and custom-designed wheels.
