What are the methods to reduce injection mold maintenance?
Strengthen scientific injection molding knowledge training and try not to damage the mold during production. Improper parameters such as low-pressure protection settings, mold closing speed, clamping force, injection speed, holding pressure, and mold temperature can greatly damage the mold.
Regularly organize training sessions for operators and technicians to ensure they have a comprehensive understanding of scientific injection molding principles. This includes the correct setting and adjustment of various parameters to prevent excessive stress on the mold. For example, setting the low-pressure protection properly can prevent damage caused by excessive impact during mold closing. Adjusting the injection speed and holding pressure can reduce internal stress in the molded part and minimize the risk of mold damage.
Implement a monitoring system to check and adjust these parameters regularly to ensure they remain within the optimal range for mold protection.
Production control. Incidents like hot runner iron block plugging and PIN needle jamming that damage the mold as shown in the table should be avoided as much as possible.
Establish strict quality control measures during production to detect and address potential issues that could damage the mold. For example, regularly inspect the hot runner system for blockages and ensure that the PIN needles are properly aligned and not prone to jamming.
Implement preventive maintenance schedules for production equipment to minimize the risk of malfunctions that could affect the mold.
Avoid inherent defects. The design and manufacturing process of plastic molds is like "pregnancy." Defects at this stage cannot be allowed, otherwise maintenance is inevitable. For example, the design of the seven major systems of the mold and materials need not be elaborated one by one.
During the mold design stage, conduct thorough engineering analysis and simulation to ensure the mold is designed for optimal per
