Event Details

  • Warping and deformation of the Table Mould https://www.furnituremould.com/products/chair-table-stool-mould/ are very difficult problems. It should be dealt with mainly from the aspect of mould planning, while the adjustment effect of moulding conditions is very limited. So, how do we deal with the warpage and deformation of the table mould injection products? 1. When stress deformation is caused by poor demoulding, it can be treated by increasing the number or area of push rods and setting demoulding slope. 2. When residual stress is deformed due to moulding conditions, the stress can be eliminated by lowering injection pressure, increasing the mould and making the mould temperature uniform and increasing the resin temperature or by annealing. 3, because the cooling method is not appropriate, make the cooling uneven or insufficient cooling time, can adjust the cooling method and prolong the cooling time, etc. For example, a cooling circuit may be provided as close to the deformation as possible. 4. With regard to the deformation caused by shortening of moulding, the mould planning must be revised. Among them, the most important thing is to pay attention to the common wall thickness of products. Sometimes, in case of necessity, one has to measure the deformation of the product, trim the mould in the opposite direction and correct it. Resins with higher shortening rate are generally crystalline resins (such AS polyoxymethylene, nylon, polypropylene, polyethylene, PET resin, etc.) with larger deformation than amorphous resins (such as PMMA resin, polyvinyl chloride, polystyrene, ABS resin, AS resin, etc.). In addition, because the glass fiber reinforced resin has fiber alignment, the deformation is also large.

  • xiu umin (owner) Chair Mould Maker'S Choice There are many types of chairs on the market. There are many changes in appearance and material. Most of them are mass-produced according to people's living habits or hobbies. Although there are many chairs and there are many ways to classify them, the chairs are mainly divided into wood, fabric, plastic, glass, and metal according to their materials. If you want to have a good chair, such a good chair mould is definitely indispensable. Moreover, the choice of the company that makes the chair mold is also very important. Good self-mold manufacturers are first-class in terms of service design or after-sales. If the chair mold wants to be good, then the first thing that needs to be treated well is its design. Because the design is not accurate, then various problems will definitely occur when making chair molds or chairs. The second is the material. There are many materials suitable for making chair molds, but everyone's needs are different. Some like aluminum, some like plastic, and some like wood. Everyone has different choices. Therefore, the angles and materials that need to be considered when making chair molds will also be different. Finally, there are some after-sales problems in the processing of chair molds, which are some places that need attention. The above are some criteria selected by the chair mold company. Of course, whether it is a chair mold or any other mold, you must be careful when choosing a manufacturer.furnituremould.com
