Cosmetics packaging material, tend to be more components, such as lipstick tube, pump head, air box, when cosmetic packaging components through methods such as injection molding, and then by electroplating, spray, such as surface treatment and color, after surface treatment, related components required by processing, which printed on the company brand and product information, cosmetics packaging material at the end of the procedure, often is the assembly of product components, viscose, welding or mechanical connection, to form the finished product, and then shipped, delivered under the brands of working procedures.
I. definition of assembly process
Assembly process, it is in accordance with the specified technical requirements, the parts will be combined into components, and further combined into parts or even the whole packaging material finished products process, respectively called assembly, there are companies called assembly, the basic task is to study under certain production conditions, with high productivity and low cost to assemble a high-quality product. The assembly process is divided into sample assembly and batch order assembly. One sample test assembly directly determines the production capacity and quality of batch order products.
Second, assembly process cognition
1. Understand the product structure: based on the product structure diagram, we can quickly know the number of structural components and associated names of the product. You can also learn the names of the structural components and the roles they play in the structure.
2. Establish the assembly order: when we understand the structure of a product, we need to know whether the component should be surface treated, printed with pictures or assembled before printing according to its characteristics. This order should be clear before assembly. Emulsion pump emulsion is a liquid cream skin care products, because it looks pure white such as milk, so called emulsion. Lotion has a good moisturizing effect, also has a moisturizing effect, especially suitable for dry spring, autumn use, if the skin is neutral, can also be used in winter. Otherwise, the wrong order, will easily cause product surface quality or structural problems. Then it is necessary to understand the assembly order between the components, according to the general principle of the assembly method is the first down and then up, first inside and then outside, first difficult and then easy, first heavy and then light, first delicate and then general.
3, determine assembly methods: cosmetics packaging products, are often composed of different material quality, metal parts, such as pieces of plastic (associated things: plastic), as a result, a packaging product is sometimes have a variety of assembly process, is the artificial viscose connection, or card buckle connections, or the mechanical assembly, depending on the product design, consider when and connection mode also directly determines the production and delivery of finished products.
4. Manage the necessary facilities of the assembly system: improve equipment debugging, personnel preparation, fixture preparation and so on. To determine the assembly process and equipment, the appropriate assembly method and the required equipment, tools, fixtures and measuring tools must be selected. When the workshop does not have ready - made equipment, tools, fixtures, measuring tools, must also put forward the design task. The process parameters can be determined by reference to empirical data or calculation. In terms of personnel, determine the quota of working hours and the technical level of workers. At present, the working hour quota of assembly is mostly estimated based on practical experience, and the technical level of workers is not strictly regulated. But experienced, skilled workers must be assigned to key assembly positions to ensure good quality.
5, start assembly, record the assembly website content: due to the various packaging material because of tolerance relation between components, so in the process of assembly, some may have not form a complete set, therefore, commonly used assembly method has swap method, replacement method, matching method, the adjustment method, so as to ensure the effective connection between each component, which link to become a qualified finished products.
