How to ensure the sealing and leak-proof performance of 3ml aluminum click pen applicator?

The sealing and leak-proof performance of the 3ml aluminum click pen applicator are ensured through a combination of precise design, high-quality material selection, and rigorous quality control measures.

The assurance of sealing performance begins at the product design stage. During the design process, engineers consider the position, shape, and material of sealing components to ensure a tight fit between them and the pen body. This includes the design dimensions, shapes, and material selection of sealing rings, as well as the precision fit between sealing components and the pen body. Through precise design, sealing components are ensured to fully conform to the pen body, preventing liquid leakage from the joints.

Material selection is crucial for sealing performance. Typically, sealing rings and other sealing components are made of high-quality silicone sealing rings or rubber sealing pads. These materials possess excellent elasticity and chemical resistance, effectively resisting liquid penetration and offering a long service life.

Precise manufacturing processes are adopted during production to ensure sealing performance. Advanced equipment and processes are utilized to ensure that each part meets precise dimensional and shape requirements. This includes injection molding, lathe machining, and precision assembly processes to ensure precise fitting between sealing components and the pen body without any gaps or flaws.

Quality control measures are essential for ensuring sealing performance. Strict quality inspections and testing are conducted during production, including liquid injection pressure testing, temperature change testing, and inversion testing. These tests verify the sealing performance of sealing components under various conditions, ensuring that the product meets standard quality requirements.

The establishment and implementation of a quality assurance system are also crucial for ensuring sealing performance. Manufacturers establish comprehensive quality management systems, including material selection and procurement, production process control and supervision, and inspection and verification of finished products. Through strict quality management, every aspect of the product is ensured to comply with quality standards and specifications.

Through precise design, high-quality material selection, precise manufacturing processes, strict quality control, and the establishment of a quality assurance system, the 3ml aluminum click pen applicator can ensure good sealing and leak-proof performance, effectively preventing leakage and external contamination of cosmetics or other liquids when not in use.
