Key Considerations When Choosing a Supplier

When it comes to car parts and components, the term OEM frequently surfaces in conversations among automotive enthusiasts, repair technicians, and everyday car owners. But what does OEM actually mean, and why is it significant in the context of car maintenance and repair?

4. Ejection Mechanisms Once the metal has cooled and solidified, it needs to be accurately ejected from the die. The ejection system must be designed to apply the appropriate force without damaging the cast part. Various types of ejection mechanisms, such as pins, plates, and hydraulic actuators, can be used, depending on the complexity and geometry of the part.

5. High Tolerance Levels Precision casting allows for very tight tolerances, which is critical in applications where component fit and performance are vital. This precision can lead to improved assembly processes and overall product reliability.

La fusione di metalli è una pratica antica che ha accompagnato l’umanità per millenni, permettendo la creazione di strumenti, opere d’arte e componenti meccanici. Tra le diverse tecniche di fusione, la colata in sabbia si distingue per la sua semplicità e versatilità. Un materiale che ha trovato impiego in questo processo è il gesso di Parigi, noto per le sue caratteristiche uniche che lo rendono adatto a creare stampi di alta qualità.

(1) The influence of casting structure: a. Casting wall thickness, large shrinkage rate, thin casting wall, small shrinkage rate. b. The free shrinkage rate is large, and the hindered shrinkage rate is small.
