Four Principles for Selecting Chair Mould Materials
The selection of Chair Mould(FURNITUREMOULD) materials is also important because it not only affects the service life of the chair mould but also directly affects the manufacturing cost of the chair mould. Therefore, some principles should be followed in selecting chair mould materials. Let's take a look below.
(1) According to the type of chair mould processing and its working conditions, the selected materials shall meet the use requirements and shall have higher strength, hardness, wear resistance, impact resistance, fatigue resistance, etc.
(2) selecting materials according to stamping materials and batch production of stamping parts; Meet the processing requirements, should have good processing performance, easy cutting processing, good hardenability, heat treatment deformation is small;
(3) To meet the requirements of the economy, various chair mould parts can be roughly divided into working surface parts, plate parts, shaft parts, sleeve parts, etc. in the processing and manufacturing of chair mould according to the similarity of parts structure and processing process. The processing methods mainly include mechanical processing and special processing. The mechanical processing methods mainly include the cutting processing of various metal cutting machines. Using common and numerical control cutting machines to carry out turning, milling, planing, boring, drilling and grinding processing can complete the processing of most die parts, and then matching with fitter operation can realize the processing and manufacturing of the whole set of dies.
(4) With the continuous improvement of the quality requirements of the chair mould processing, the mould materials with special properties such as high strength, high hardness, and high toughness are appearing continuously and the number of complex profiles and holes is increasing. The traditional mechanical processing methods have been unable to meet the requirements of mould processing. Therefore, the process methods of directly using electric energy, heat energy, light energy, chemical energy, electrochemical energy, acoustic energy, and other special processing have been developed rapidly. At present, the special processing methods mainly based on electrical processing have been widely used in modern mould manufacturing, which is an important supplement to the mechanical processing methods.
