Mold management should be standardized to ensure longevity.
Molds that have been used for a long time must have their blades sharpened. After sharpening, the blade surface must be demagnetized. The company using the molds should keep detailed records, including statistics on usage, maintenance (lubrication, cleaning, rust prevention), and damage conditions. They should also categorize based on the damaged areas and wear levels to provide information for troubleshooting and solutions. Additionally, having the molding process parameters for the materials used in molds and products can shorten the trial run time of molds and improve production efficiency.
1:MoldAfter prolonged use, the blades must be sharpened, and after sharpening, the blade surface must be demagnetized. The company using the mold should keep detailed records, including usage, maintenance (lubrication, cleaning, rust prevention), and damage status. Statistics should be compiled based on the damaged areas and wear levels to provide information for troubleshooting and solutions. Additionally, the molding process parameters of the materials used for molds and products can shorten the trial run time of molds and improve production efficiency. The performance of molds should be tested under normal operation conditions of injection molding machines and molds, measuring the dimensions of the final molded plastic parts. This information can be used to determine the current state of the mold and then assess the damage status of cavities, cores, cooling systems, and molds based on information provided by sealing materials.
2: Springs and other elastic components are most prone to damage during use, often breaking or deforming. The method used is replacement. During replacement, pay attention to the specifications and models of springs. The specifications and models of springs are determined by color, outer diameter, and length. They can only be replaced when all three items match. Imported springs have better quality.
3: During useMold, punchers are prone to breakage, bending, or biting off; they often damage the punch sleeve. Usually replace damaged punches and sleeves with parts of the same specifications. The parameters of a punch press mainly include dimensions of working parts and installation parts.
4: Fastening parts should be checked for looseness or damage. The method used is to find replacements with matching specifications.
5: Material pressing plates such as pressing components, discharge plates, pneumatic injectors etc., need maintenance; check for relationships between components and any damages; repair damaged components; check for air leaks through pneumatic lifting; take measures according to specific situations. If air pipes are damaged, they should be replaced. It is important to closely monitor several key components in testing molds: ejector guiding components ensure mold opening/closing movement as well as ejection of plastic parts. If any part of the mold gets stuck due to damage, production will halt; therefore regular maintenance is essential. Lubricate ejector pins and guide posts (the most suitable lubricant should be chosen) and regularly check for deformation or damage on their surfaces; once found they must be replaced promptly; after completing a production cycle, professional anti-rust oil must be applied to moving surfaces and guiding parts of molds with special attention given to protecting load-bearing elastic strength spring sections in gear rack molds to ensure they remain in optimal working condition; as production time extends cooling channels tend to accumulate scale deposits like rusts muds algae which reduces cross-sectional area leading to narrower cooling channels resulting in significantly reduced heat exchange rates between cooling fluids increasing enterprise production costs.Mold, maintenance of heating and control systems is very important as it helps prevent production failures.
