The Taizhou Huaxi Mould Co Ltd, located in the Huangyan District of Taizhou City – and a recent new member of IMD online – has been established for more than 10 years, mainly in the production of daily-use plastic moulds. The business is based on sound considered technology and exceptional production development skills. The company has invested in quality advanced equipment, which allows Huaxi Mould to always deliver to its customers high quality mould products every time.
Every year Huaxi produces around 200-300 mould sets, mainly chairs, tables, stools, storage crates, dustbins, baskets, flowerpots and more.
Huaxi moulds are mainly exported to Europe, North America, The Middle East, Asia and Africa. Here the company experts review a key aspect of the effective mould product process … the effect,control and management of mould temperature….
Appropriate mould temperature can ensure the melt flow and cool the product. Mould temperature represents the temperature of the mould cavity, not the temperature indicated on the mold temperature machine. Generally, the cavity temperature reaches a stable dynamic equilibrium during stable production and is higher than the indicated temperature of about 100 degrees C. For large plastic moulds , the mould must be fully heated (especially thin-walled and long-flow) before injection. Product moulds should be more similar.
Mould temperature affects fluidity, which affects melt fluidity and cooling rate. It affects the flow rate, thus the cooling rate, and thus the appearance (surface quality, burrs) and injection pressure of the product, which in turn affects the crystallinity of the product. Product shrinkage and mechanical strength characteristics.
Due to the high mould temperature, good melt fluidity, high crystallinity of the plastic, large shrinkage of the product, small size, easy deformation of the product, long cooling time, low mould fluidity, poor melt fluidity, leading to assembly lines. Due to trace amounts, low crystallinity, and small shrinkage, their sizes increase.
For plastic injection moulding, the mould temperature depends on the physical and chemical properties of the plastic, the fluidity and surface quality of the product. Generally, the mould temperature is set as high as possible to reduce the flow resistance of the melt and quickly fill the mold. The melt is cooled and solidified at a uniform rate.
However, the higher the mould temperature, the smoother the surface, the more pronounced the depressions, and the longer the moulding cycle. Therefore, the moulding cycle and product pre-requisites must be fully considered to determine the temperature.
