Hardening speed of molten plastic in molding
At current, the use of injection molded products has been quite extensive in our daily life, and more and more companies are engaged in this business. As an industry that is easily affected by external factors and molding machine settings, injection molding requires reasonable settings for different materials, environments, to ensure the production that meet expectation of customers.
Injection molding process is the process of shaping the molten plastic into the designate shape, so the control of the hardening speed of the plastic determines the efficiency and quality of the products, what are the main factors that affect the hardening speed?
First of all, the hardening speed of molded parts has a greater relationship with the raw material, the structures, wall thickness, molding temperature, etc. The mold engineer can set reasonable gate and runner design by combining the structure shape and the flow speed of the raw material. For narrow products, the injection molding process can be simulated by mold flow analysis software to prevent short-shot defect.
By controlling the mold temperature, the hardening speed of the plastic can also be improved, and it also means the molten plastic can fill the cavity more easily during the processing cycle.
Reasonable control of the hardening speed of the plastic material can shorten the molding cycle and improve the efficiency. At the same time, for material that harden too fast, they cannot meet the production requirements of complex molding parts if certain external conditions are not meet. Shanghai Future Mould can assist you to complete the mold manufacturing and mass production of plastic parts, offering you cost-effective molding services.
