Self -Moisturizing Slide Stationary Core Units are specially designed core units commonly used in applications such as mold making and injection molding. It has self-lubricating properties that reduce friction and wear, improve operating efficiency and extend service life. Self -Moisturizing Slide Stationary Core Units are usually manufactured with high-quality self-lubricating materials, such as self-lubricating alloys or engineering plastics with lubricating properties. This material has good lubricating properties and can form a self-lubricating film between the core part and other parts, reducing friction and wear.
