【Features】 ▶ Can mark on water and oil surfaces ▶ The line is easy to see as it reflects in the arc during welding ▶ Resistant to breaking ▶ Economical with replaceable leads for repeated use ▶ Equipped with a pencil sharpener for easy fine writing at any time
In plastic molding engineering, gases generated from the resin and air trapped in the resin are the causes! Here are the countermeasures.
Silver streaks, referred to as "silver," are defects that occur on the surface of resin products, resulting in silver lines. The causes include "gases generated from within the resin" during the plasticization process, "air trapped in the resin," and "air trapped in the mold during the injection process." In response, measures such as setting a lower resin temperature or using a cylinder with gas vents are employed to suppress gas generation. [Causes] ■ Gases generated from within the resin during the plasticization process ■ Air trapped in the resin during the plasticization process ■ Air trapped in the mold during the injection process *For more details, please refer to the PDF document or feel free to contact us.
