　　Preparation of racket embryo: Prepare the racket embryo with the racket body and handle in advance through a specific process (such as molding, etc.).

　　Mould installation and positioning: Accurately install the racket mold at the corresponding position of the injection molding machine to ensure that the key parts such as the mold cavity and the injection molding system are accurately matched.

　　Feeding and melting: Add plastic particles to the hopper of the injection molding machine, and gradually melt the plastic particles into a liquid state through the heating system of the injection molding machine (such as resistance heating, etc.), and convey them forward under the push of the screw, etc.

　　Injection stage: After reaching the appropriate fluidity and other states, the liquid plastic is injected into the mold cavity where the racket embryo has been placed under a certain pressure, and the liquid plastic will flow and fill along the outer peripheral side of the racket embryo.

　　Cooling and shaping: The plastic entering the mold cavity is cooled quickly through the mold’s own cooling channel (such as cooling water), and the plastic gradually solidifies and tightly wraps around the outer peripheral side of the racket embryo to form a rim.

　　Demolding: The mold is opened by the mold opening mechanism (such as hydraulic or mechanical drive, etc.), and the finished racket with rim is removed from the mold by the ejection mechanism (such as ejector rod, etc.).

　　Working principle of hot pressing rimming automatic equipment (hypothetical situation):

　　Edge material delivery: The pre-prepared rimming material (such as rubber strips, TPU strips, etc.) is released from the unwinding device at a certain speed and tension, and transported to the working area through conveyor tracks or rollers.

　　Racket positioning: The pickleball racket is placed on a specific working platform through a mechanical arm or conveyor belt, and the racket position is ensured to be accurate through positioning mechanisms (such as clamps, sensor induction, etc.).

　　Preheating: Before the hemming contacts the racket, the hemming material and/or the hemming area of the racket are preheated. The material can be softened by infrared heating, hot air heating, etc. to facilitate subsequent bonding.

　　Hot pressing bonding: The hemming material is pressed tightly against the edge of the racket by using a hot pressing head (with a certain shape and temperature control) to make the hemming material tightly bonded to the edge of the racket under the action of pressure and temperature.

　　Cooling and curing (if necessary): After hot pressing, the hemming material is quickly cured and shaped on the racket by air cooling or other cooling methods.

　　Trimming (if necessary): Use a knife or laser to cut off excess hemming material.
