Plastic Mold Maintenance

An intensive production process can wear molds out, break, or become less efficient. What to do? The solution is plastic mold maintenance. Discover in the following article all the details about it.



Extending the life of the molds is the most efficient way to reduce production costs and guarantee the perfect final product. Worn or damaged molds can compromise the accuracy of the performance. For this reason, it is important to execute proper scheduled and precautionary maintenance operations in order to avoid their replacement.



Plastic Injection Mold Maintenance

Maintenance consists of a series of operations that are functional to the durability of the plastic injection mold. 


Let’s delve into these phases. 




Cleaning procedures ensure the longevity and efficiency of your plastic injection mold. In fact, these protocols optimize the output performance by eliminating residue and contaminants, guaranteeing the maintenance of the product. 



Wear Level Control

In order to extend the lifespan of plastic injection molds, a core maintenance procedure you can perform is to accurately control wear level on a regular basis. These assessments will help you address wear-related issues, minimizing downtime. 



Worn Out Parts Reconstruction 

The reconstruction of worn out components, such as edges, input and output zones and shears is an instrumental operation to restore the full functionality of the part, saving time and resources. 




In this case, the maintenance of plastic injection molds consists of promptly repair processing errors, breaks and cracks that could compromise the structural integrity of the mold. This is an effective way to cut replacement costs and restore the peak performance of the mold. 



Reset of Ruined or Damaged Parts

Whether a mold part results ruined or damaged due to wear, misuse or other factors, the component can be reset. In this way, functionality is restored to ensure consistent quality. 



Innovative Technologies 

With groundbreaking, state-of-the-art technologies, such as an optical scan, it is possible to rebuild the 3D model of the component, if not entirely build the whole plastic injection mold. This advanced maintenance tool is capable of enhancing the reliability and durability of the part.

Laser Welding: The Most Effective Method for Mold Maintenance

Whether a normal or special repairs - such as micro-welding at high precision - are required, laser welding has become the main technique used for plastic mold maintenance procedures. This kind of welding can be applied to molds of every dimension and material, such as steel, bronze, copper, aluminum and titanium, with hardness to 60 HRC.


This advanced method allows to fully restore the mold, making changes that do not distort it or let it lose its main features like geometry and dimensional tolerances.



The Advantages Of Plastic Mold Maintenance 

Laser welding allows operating also in small areas. In this way, it is feasible to avoid the risk of overheating.


Moreover, this technique:

  • is a quick maintenance method, ideal also for those who can not afford an extended stop;
  • is extremely precise;
  • guarantees a great work flexibility.


Optimize Your Molds With Precautionary Maintenance

Production rates that are particularly intense can lead the molds to an early wearing. Since prevention is better than cure, a precautionary plastic mold maintenance will help you to optimize your molds lifetime.


Scheduled maintenance, in fact, includes a regular monitoring of the molds to find the most worn out spots and avoid the risk of breaks which would cause a more extended stop.
