Quality Control in Injection Molding​
In injection molding, visual inspection is often the first line of quality control. Operators carefully examine the molded parts for visible defects such as cracks, warping, and flash. Cracks can occur due to excessive stress during the molding process or improper material selection. Warping may be caused by uneven cooling or incorrect mold design. Flash, which is excess plastic that seeps out of the mold, can be a sign of issues with the mold closing or excessive injection pressure.​
Dimensional inspection is also crucial. Using precision measuring tools like calipers, micrometers, and coordinate measuring machines (CMMs), manufacturers ensure that the molded parts meet the specified dimensions. Even a slight deviation from the tolerances can affect the functionality and fit of the parts. For example, in the production of plastic gears, precise dimensional control is essential to ensure smooth meshing and proper operation.​
Injection molding companies also conduct functional testing on their products. For instance, if the molded part is a plastic hinge, it will be tested for its ability to open and close smoothly and withstand a certain number of cycles. Material testing is another important aspect. Samples of the plastic material used in the molding process are tested for properties such as tensile strength, impact resistance, and heat resistance to ensure that they meet the required specifications.​
Quality Control in Metal Manufacturing​
In metal manufacturing, non - destructive testing methods are widely employed. Ultrasonic testing is a popular method for detecting internal defects in metal parts. High - frequency sound waves are introduced into the metal, and any reflections from internal defects, such as cracks or voids, are detected. X - ray inspection is also commonly used. X - rays can penetrate the metal and reveal hidden flaws, allowing manufacturers to identify and address issues before the parts are further processed or assembled.​
Mechanical testing is another crucial part of quality control in metal manufacturing. Tensile testing is used to determine the strength of the metal by pulling a sample until it breaks. Hardness testing measures the resistance of the metal to indentation, which is an indicator of its wear resistance. Impact testing assesses the metal's ability to withstand sudden loads. These tests help ensure that the metal parts have the required mechanical properties for their intended applications.​
Both injection molding and metal manufacturing industries rely on quality management systems.
