What Factors Can Affect The Service Life of Plastic Molds
Plastic molds play a crucial role in the production of plastic products. However, its lifespan is constrained by various factors. Let's explore in detail which factors can significantly affect the service life of plastic molds.
1.Mould material
The quality of materials used in plastic molds is one of the key factors determining their service life. High quality mold steel, such as P20, H13, etc., has excellent wear resistance, hardness, and toughness, and can withstand long-term production use.
For example, if poor quality mold materials are used, they are prone to wear, deformation, and even cracking during frequent injection molding processes, greatly shortening the service life of plastic molds.
Reasonable mold design is crucial for extending its service life. Good flow channel design can ensure uniform filling of the mold cavity with plastic and reduce excessive local pressure; A reasonable cooling system can effectively control the temperature of the mold, avoiding deformation and cracks caused by thermal expansion and contraction.
For example, plastic molds with uneven distribution of cooling water channels may experience thermal fatigue during production due to local high temperatures, which can affect their service life.
Accurate processing technology can ensure the dimensional accuracy and surface quality of the mold. High precision machining can reduce the fitting error of molds and decrease the degree of wear.
For example, in the processing of mold cavities, if the roughness is large, it will increase the friction between the plastic and the mold, accelerating the wear of the mold.
4.Mold usage and maintenance
The correct usage method and regular maintenance are important guarantees for extending the life of plastic molds. Operators should follow the operating procedures to avoid overloading and improper operation.
For example, if the mold is in an overpressure state for a long time during the production process, it will damage the mold structure and shorten its service life. At the same time, regular maintenance such as cleaning, lubrication, rust prevention treatment, etc. can effectively prevent mold rusting and corrosion.
5.Production environment
The temperature, humidity, and cleanliness of the production environment can also affect the service life of plastic molds. High temperature and high humidity environments can easily cause rusting and corrosion of molds, while dust and other impurities may enter the interior of the mold, causing wear and damage.
