plastic rattan garden furniture mold Molding cycle

Molding cycle: molding cycle directly affect labor productivity and equipment utilization. Therefore, in the production process, should be under the premise of guaranteeing quality, shorten MASTER injection mould design  the molding cycle of each relevant time. Throughout the molding cycle, injection time and cooling time of the most important quality of the product which has a decisive influence. Injection time of filling time directly inversely proportional to the filling rate, the production of filling time usually about 3-5 seconds. Injection plastic rattan garden furniture mold Molding cycle time of dwell time is on plastic cavity pressure time throughout the greater the proportion of injection time, usually about 20-120 seconds (special thick workpieces up to 5 to 10 minutes). Before the gate to melt frozen, Paul how much pressure of time, affect the accuracy of product size, if in the future , MASTER plastic chair mold  was not affected. Dwell time is also the most favorable value, it is known to depend on the melt temperature, mold temperature and the size of the main channel and the gate. If the main channel and the gate size and process conditions are normal, usually derived products shrinkage that is the smallest fluctuation range of pressure values ​​prevail. MASTER injection mould design  Cooling time depends mainly on the thickness of the article, the thermal properties and crystallization properties of the plastic and the mold temperature and the like. End of the cooling time should be to ensure that the products do not cause changes in release when the principle of the cooling timing between typically about 30 to 120 seconds, the cooling time is too long is not necessary, not only to reduce the production efficiency, complicated parts will cause stripping difficulties, even when forced to produce release stress release. Other molding cycle time of the production process is continuous and automated, and the degree of automation and related continuous.
