What Are The Characteristics of Household Product Mould
The main characteristics of the temperature control of the Household Product Mould(FURNITUREMOULD) include: the temperature set by the controller is consistent with the temperature of the household product mould; The thermal factors that affect the household product mould can be directly measured and compensated. In general, the stability of the mould temperature for household products is better than that by controlling the fluid temperature. In addition, the repeatability of mould temperature control for household products in production process control is good. The third is joint control. Joint control is a combination of the above methods, which can control the temperature of the fluid and household product mould simultaneously. In the joint control, the position of the temperature sensor in the household product mould is extremely important. When placing the temperature sensor, the shape, structure and the position of the cooling channel must be considered. In addition, the temperature sensor should be placed in a place that plays a decisive role in the quality of injection moulded parts. There are many ways to connect one or more mould temperature machines to the controller of the injection moulding machine. It is best to use a digital interface from the viewpoint of operability, reliability, and anti-interference. Information can be transmitted between the control unit and the injection moulding machine through software. The mould temperature machine can also be controlled automatically.
Heat balance control of household product mould The heat conduction between the injection moulding machine and mould is the key to produce injection moulded parts. Inside the mould, the heat brought by plastic (such as thermoplastic plastic) is transferred to the material and the steel of the mould through thermal radiation and transferred to the heat-conducting fluid through convection. In addition, heat is transferred to the atmosphere and the mould frame through thermal radiation. The heat absorbed by the heat-conducting fluid is taken away by the mould temperature machine.
The purpose of controlling the mould temperature of household products and the influence of the mould temperature of household products on injection moulded parts In the injection moulding process, the main purpose of controlling the mould temperature of household products is to heat the mould to the working temperature and to keep the mould temperature constant at the working temperature. If the above two points are successful, the cycle time can be optimized to ensure a stable high quality of injection moulded parts. The mould temperature of household products will affect the surface quality, fluidity, shrinkage, injection cycle, and deformation. Excessive or insufficient mould temperature for household products will have different effects on different materials. For thermoplastics, a higher mould temperature for household products usually improves surface quality and fluidity but prolongs cooling time and the injection cycle. A lower mould temperature for household products will reduce the shrinkage in the mould but will increase the shrinkage rate of the injection moulded parts after demoulding. For thermosetting plastics, a higher mould temperature for household products usually reduces the cycle time, which is determined by the time required for cooling the parts. In addition, in plastic processing, a higher mould temperature for household products will also reduce plasticizing time and cycle times.
