"Plastic mold steel model hardness: the key to creating a perfect mold"
In the mold manufacturing process, the hardness of the plastic mold steel model is the key factor that determines the quality of the mold. Choosing the right steel type and hardness ensures durability, accuracy and productivity of your molds. This article will explain the importance of the hardness of plastic mold steel models, and how to choose the right steel and hardness to achieve the best mold performance.
First, the importance of plastic mold steel model.
The selection of the steel type of the plastic mold is crucial to the performance of the mold. Different steel grades have different physical and chemical properties, such as strength, toughness, corrosion resistance, etc. Therefore, choosing the right steel type can improve the durability, accuracy and productivity of the mold.
Generally speaking, the commonly used steel types for plastic molds include: 45, CR12, CR12MOV, SKD, etc. These steel models all have good toughness and wear resistance, which can meet the needs of different types of molds.
Second, the selection of plastic mold steel hardness.
The hardness of plastic mold steel is another important indicator to measure the performance of the mold. Hardness can affect the wear resistance, impact resistance and service life of the mold. Generally speaking, the higher the hardness, the better the wear and impact resistance of the mold, but at the same time, it also requires higher process requirements and manufacturing costs.
When choosing the hardness of plastic mold steel, the following factors need to be considered:
Generally speaking, the steel hardness commonly used in plastic molds includes: HRC50-65, HRC60-75, etc. Depending on the specific needs, the selection of the appropriate steel hardness and hardness range can better meet the production requirements.
3. How to achieve the best hardness of plastic mold steel model.
In order to achieve the best steel type hardness of plastic molds, the following measures need to be taken:
In short, the selection of plastic mold steel type and hardness is the key link in the manufacture of high-quality molds. By fully understanding the requirements, considering the process requirements, referring to industry standards, and regular maintenance, the best hardness selection and use effect of plastic mold steel models can be achieved.
