Injuries caused by temperature rising too quickly during injection molding
In the case of injection molding processing, it will undoubtedly be applied to injection molding machine equipment, it is a process that cannot be missing in the entire production process, and its necessity cannot be ignored. However, in the case of the application of injection molding machine for production and processing, we must pay attention to the difficulty of the temperature rise of the equipment too quickly, which is likely to lead to great shortcomings.
If the temperature of the injection molding machine rises too fast, it is likely to cause injection processing deformation, which will cause certain harm to the precision of the transmission system software and the quality of its injection molding components. And after the temperature is too high, the viscosity of the oil will be reduced, resulting in oil leakage, and the equipment will be caused by great friction in operation. The embrittlement difficulty of injection molded products may be more serious and cannot be applied for a longer period of time.
The molding cycle time of injection molding products, which includes injection molding processing time and product cooling time, this reasonable control of time has an unforgettable harm to the quality of the product.
In the past injection molding production, the product molding cycle time should be established according to the style of the sample and other methods.
The temperature of the plastic mold, different plastic particles, the temperature and speed of the crystal are all different, and the appearance, deformation, specifications, rubber molds, etc. of its products have different regulations;
This has prompted the temperature of the plastic mold to be controlled differently under the application of different plastics, product regulations, etc.
Melting plastic injection working pressure, plastic in the whole process of filling the abrasive die is to cope with a lot of frictional resistance, which promotes the size of the injection pressure to determine the product specifications, net weight, relative density, appearance, etc.!
Harm all one of these elements, then the product becomes scrap. It is necessary for injection technology engineers to effectively define injection work pressure control according to the general elements of the product.
Injection speed, injection speed has a key hazard to the appearance quality of the product.
The injection speed generally must be completed according to the amount of oil supplied to the injection hydraulic cylinder per unit time.
Barrel temperature and melt temperature, melt temperature can be measured at the nozzle or apply the gas injection method to measure, the melt temperature is a key achievement on the flow performance of the melt;
Plastics have no actual melting point, which is a temperature segment under a molten state.
