Mold quality inspection is a comprehensive evaluation of mold performance and accuracy, and is a key link in ensuring product quality, improving production efficiency, and reducing production costs. The stability of mold quality directly affects the appearance, size, and performance of the product. Therefore, through mold quality inspection, potential problems with the mold can be detected in a timely manner, avoiding the occurrence of batch defective products in the production process, reducing waste, and lowering production costs. At the same time, mold quality inspection is also an important basis for mold maintenance and repair, which helps to improve the service life of molds and reduce the number of repairs.
1、 Common mold quality inspection methods
1. Non destructive testing technology
Non destructive testing technology refers to the use of physical, chemical, or non-destructive testing methods to inspect molds without affecting their performance. Common non-destructive testing techniques include:
(1) Appearance inspection: The surface of the mold is inspected by visual inspection, magnifying glass or scanner to observe whether there are cracks, deformations, wear, corrosion and other damages on the mold.
(2) Dimensional inspection: Use measuring tools such as vernier calipers, micrometers, dial gauges, etc. to measure the dimensions and geometric accuracy of the mold.
(3) Hardness testing: The hardness of the mold is tested using a hardness tester to evaluate the wear resistance and corrosion resistance of the mold material.
(4) X-ray inspection: using X-rays to perform non-destructive testing on the interior of the mold to detect defects such as cracks and pores.
(5) Ultrasonic testing: By emitting ultrasonic waves into the interior of the mold, using echo signals to detect defects such as cracks, pores, etc. inside the mold.
2. Destructive detection technology
Destructive testing technology refers to the use of sampling, cutting, grinding, and other methods to test molds without avoiding certain damage to the molds. Common destructive detection techniques include:
(1) Metallographic testing: Obtaining small samples of molds through cutting, grinding, polishing, and other methods, observing their metallographic structure through a microscope, and evaluating the microscopic properties of mold materials.
(2) Tensile test: By conducting tensile tests on mold materials, evaluate their mechanical performance indicators such as tensile strength and yield strength.
(3) Wear resistance testing: Conduct wear resistance testing on mold materials through a wear testing machine to evaluate their wear resistance and corrosion resistance.
(4) Fatigue testing: By conducting fatigue testing on the mold, evaluate its anti fatigue performance under cyclic loading.
2、 Practical strategies for continuous improvement of mold quality
1. Establish a comprehensive mold quality inspection system
Establishing a comprehensive mold quality inspection system is the key to improving mold quality. Enterprises should develop detailed mold quality standards and testing processes based on their own production characteristics and needs, clarify the testing methods and responsible persons for each link, and ensure that the quality of each link is effectively controlled. At the same time, the mold quality inspection system should be regularly reviewed and updated to meet the market's demand for continuously improving product quality.
2. Improve the skill level of testing personnel
The skill level and professional competence of the testing personnel are key factors in ensuring the accuracy of mold quality testing. Enterprises should strengthen the training and skill assessment of testing personnel to ensure that they master advanced testing techniques and instrument operation methods. At the same time, incentive mechanisms should be established to enhance the enthusiasm and sense of responsibility of testing personnel.
3. Introduce advanced testing equipment and instruments
With the continuous advancement of technology, the application of advanced testing equipment and instruments in mold quality inspection is becoming increasingly widespread. Enterprises should actively introduce advanced testing equipment and instruments to improve the accuracy and efficiency of testing. At the same time, attention should be paid to equipment maintenance and upkeep to ensure the long-term stable operation of the equipment.
4. Strengthen cooperation and communication with suppliers
The quality of mold materials and the service level of suppliers have a significant impact on the quality of molds. Enterprises should strengthen cooperation and communication with suppliers, establish long-term stable cooperative relationships, and jointly improve the quality of molds. At the same time, it is necessary to strengthen the evaluation and assessment of suppliers to ensure that the mold materials they provide meet the requirements.
