Quality control of furniture products in China, Vietnam, Malaysia and Cambodia, procurement specialist, quality inspector,
Guide: To control the quality of furniture products, product design must be strictly controlled. The design shall ensure that the design meets the requirements of relevant standards. The National Bureau of Quality Supervision has a series of mandatory standards for furniture products, such as standards, materials, processing accuracy and environmental protection.
To control the quality of furniture products, product design must be strictly controlled. The design shall ensure that the design meets the requirements of relevant standards. The National Bureau of Quality Supervision has a series of mandatory standards for furniture products, such as standards, materials, processing accuracy and environmental protection. Design investigation, market forecast and product decision shall be made; After preliminary design, model making and construction design.
Improve product structure design. The designer shall guide the sample production. After the sample production, it is necessary to further verify whether the product meets the design requirements from the aspects of product function, structure, materials, processing, decoration, etc., and whether the product specification, structure, and materials used are incorrect; In case of technical and quality problems, the construction drawings shall be modified in a timely manner. During mass production, the design representative shall track the process by process and correct the problems found in a timely manner.
1、 The basic scale of human body and the scale of human activity are the most basic basis for furniture function design, for which ergonomics has been deeply researched. The design of furniture products should consider the different requirements and application occasions of users, and study the general range suitable for the general population. The concept of “percentile” should be used in furniture design, and 95% of the general purpose furniture should be suitable, so that 95% of people feel that the product is suitable.
For special requirements such as star rated hotels and presidential suite furniture, the design scale exceeds the normal scale in consideration of social status, wealth, self-esteem and other factors; Develop special furniture with good stability and high safety for specific groups, such as children, the elderly and the disabled; For schools, hospitals, office furniture, etc., full consideration should be given to relevant standards and standards, and design should be combined with user requirements.
2、 The use of materials is scientific and reasonable, and many materials are used to produce wooden furniture in line with environmental requirements, among which wood and wood-based panels are the most used. For the wood used to make furniture, the influence of its moisture content change on the size, shape variation and strength of components shall be fully considered in the design. The base material must be manually dried, and the final moisture content shall not be higher than the equilibrium moisture content of the product location plus 1%. Use the natural patterns, color changes and different textures of wood to design different styles of furniture, such as: ancient pine, noble and elegant cherry, and stable birch.
For example, in the 10 mandatory standards such as GB18584-2001 Limit of Harmful Substances in Interior Decoration Materials and Wood Furniture issued and implemented by China in 2002, the wood-based panels, adhesives and paints used in the production of wood furniture should meet the requirements of the limit values for the release of free formaldehyde, benzene, total organic volatile substances, heavy metals and other harmful substances.
3、 The structural design of wooden furniture should be firm and reliable. Designers should fully master the production process of furniture and the structure of parts and components. In view of the quality problems that are easy to occur in panel furniture and solid wood furniture, such as the cracking of wood furniture itself, the cracking at the splicing (finger joint), structure and veneer composite, the bending deformation of door opening, horizontal panel and vertical panel, the looseness and fall off of tenon and mortise structure, the looseness of disassembly and assembly structure in panel furniture and other quality defects, find out the unreasonable parts in the structural design and take measures to solve them.
Glue joint, mortise tenon joint, straight nail joint, wood screw joint, threaded rod joint shall be adopted for the fixed structure of wooden furniture, and auxiliary measures shall be taken if necessary, such as triangular wood, connecting wood, etc. In order to prevent cracks at the material splicing part, straight V-shaped or U-shaped process grooves are added at the splicing part, and the horizontal parts at the connection part are indented 1mm~3mm into the longitudinal parts. The surface of the parts in contact with the human body must be smooth, and the edges and corners of the product must be slightly chamfered or rounded.
