Warping and deformation of injection moulded products of Household Product Mould are very difficult problems. It should be mainly solved from the aspect of mould design, while the adjustment effect of moulding conditions is very limited. So, how do we solve the warpage and deformation of household product mould products? 1. When stress deformation is caused by poor demoulding, it can be solved by increasing the number or area of pushrods and setting demoulding slope. 2. When deformation is caused by residual stress caused by moulding conditions, stress can be eliminated by reducing injection pressure, increasing the mould and making the mould temperature uniform and increasing the resin temperature or by annealing. 3. If the cooling method is not suitable and the cooling is uneven or the cooling time is insufficient, the cooling method can be adjusted and the cooling time can be prolonged. For example, a cooling circuit may be provided as close to the deformation as possible. 4. For the deformation caused by moulding shrinkage, the design of the mould must be revised. Among them, the most important thing is to pay attention to make the product wall thickness consistent. 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 larger shrinkage rate are generally crystalline resins (such AS polyoxymethylene, nylon, polypropylene, polyethene, PET resin, etc.) with larger deformation than amorphous resins (such as PMMA resin, polyvinyl chloride, polystyrene, ABS resin, AS resin, etc.). In addition, since the glass fiber reinforced resin has fiber alignment, the deformation is also large. Taizhou Huangyan Rongwei Plastic Mould Co.,Ltd.is located in Huangyan,which is the mould town in China. Our company have more than 20 years professional experience in mould field.
