What is The Drying Temperature For PC+ABS Plastic Injecting Molding?

PC+ABS plastic mold injection molding

The drying temperature of PC+ABS plastic molds is an important process parameter that directly affects the flowability of materials and the quality of products during injection molding. Generally speaking, the drying temperature range for PC+ABS plastics is between 100-120 ℃, but the specific temperature needs to be determined based on the material ratio (the ratio of PC to ABS), the specific data provided by the material supplier, and the type of injection molding machine (such as plunger or screw).

The Importance of Drying Temperature

·Moisture removal: The main purpose of drying materials is to remove moisture from the material, avoiding the formation of bubbles or affecting the flowability of the material during injection molding.

·Raising the material temperature: An appropriate drying temperature can help the material reach a certain temperature before injection molding, which is beneficial for the uniform flow and plasticization of the material in the injection molding machine.

Specific setting of drying temperature

·Basic range: Typically, the drying temperature for PC+ABS plastics is set between 100-120 ℃. This range is a rough reference, and the specific values need to be adjusted according to the actual situation.

·Material ratio: If the proportion of PC in the material is high, the drying temperature may be appropriately increased; On the contrary, if the proportion of ABS is high, the drying temperature can be slightly lower.

·Supplier data: Material suppliers usually provide detailed recommendations for drying temperature and time, which are important basis for setting drying parameters.

·Injection molding machine type: Different types of injection molding machines may have different requirements for drying temperature. For example, a plunger injection molding machine may require a slightly higher drying temperature to ensure sufficient plasticization of the material.

Drying time

In addition to the drying temperature, the drying time is also an important parameter. Generally speaking, the drying time needs to be long enough to ensure that the moisture in the material is fully removed, but it should not be too long to avoid material aging or degradation. The specific drying time also needs to be determined based on the characteristics of the material and the supplier's recommendations.

matters needing attention

·When setting the drying temperature and time, it is necessary to comprehensively consider the characteristics of the material, the type of injection molding machine, and the quality requirements of the product.

·During the drying process, the temperature and humidity control of the drying machine should be regularly checked to ensure the stability and accuracy of the drying parameters.

·The materials after drying should be used as soon as possible to avoid long-term storage that may cause a decrease in material properties.
