How Long Does a Plastic Mold Last?
The lifespan of a plastic mold is a complex issue without a fixed answer. Numerous factors influence its service life, including:
Mold Material: High-quality mold steel, such as those with excellent wear resistance and tensile strength, can significantly extend mold life.
Mold Design: A rational design can effectively reduce stress concentration in the mold and minimize wear.
Manufacturing Process: A precise manufacturing process ensures dimensional accuracy and surface quality, prolonging the mold's service life.
Operating Conditions: Injection molding pressure, temperature, and the properties of the plastic material all affect the mold's lifespan.
Maintenance: Regular cleaning, lubrication, and inspection of the mold can effectively extend its service life.
Generally, the lifespan of a plastic mold can range from a few thousand to hundreds of thousands of injection cycles.
How to Extend Mold Life?
Select the Appropriate Mold Steel: Choose the suitable mold steel based on the product's complexity and production volume.
Optimize Mold Design: Reduce stress concentration and improve the mold's rigidity.
Strictly Control the Machining Process: Ensure the mold's dimensional accuracy and surface quality.
Set Reasonable Injection Process Parameters: Avoid excessively high injection pressure and temperature.
Regularly Inspect and Maintain the Mold: Timely detect and address mold defects.
