Resin temperature and mold temperature for injection mold forming conditions

The quality of injection molding products produced from the mold will be affected by the adjustment of molding conditions. If the adjustment range of condition adjustment parameters is larger, the range of quality specifications will also be larger, and the adjustment operation becomes easier. Generally speaking, when "mold quality is good", it is often said that the range of this condition adjustment is large.

Resin temperature for injection mold forming conditions

The resin temperature can be adjusted by setting the temperature of the injector barrel. The correct setting range of resin temperature is determined according to the grade of resin, with reference to the recommended temperature range provided by each resin manufacturer. When you want to measure the actual resin temperature, you can use a thermocouple thermometer by inserting a thermocouple into the injected resin.

Mold temperature for injection molding conditions

Mold temperature is an important parameter which affects the shrinkage and surface transfer of mold cavity. Generally speaking, in the temperature range of 15 ~ 90℃ is the use of water cooled temperature controller for mold temperature regulation. If the temperature exceeds 90°C, use a pressurized water type, oil temperature controller, or use a cylinder heater for temperature control.

Although it is the temperature of the injection mold that is controlled, what really matters is the surface temperature of the cavity. In order to control the mold accurately, the usual method is to use the contact surface thermometer, according to the measured temperature value to adjust the mold temperature.

In order to obtain the desired quality of injection molding products, it is necessary to adjust the various parameters on the injection molding machine called "molding conditions", while controlling the size and appearance quality of the condition adjustment operations to meet the specifications. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the life is long, the mass production is fast and the finished product quality is excellent!
