What This Is
Think of our ejection sleeve as the reliable hand inside your Huayan machine. Its job is simple but critical: every single cycle, it must push the newly molded hot preform out of the mold without a scratch. At Baijinyi, we’ve been making these since 2011. We know that a good sleeve keeps your line running fast and your product quality high. This component works as part of a full set, pairing with the take-out tube and cooling core for a seamless finish.

Important: Don’t see your exact need here? No problem. We make sleeves to match your machine’s specs, not just ours. Send us your requirements.
What It’s Made Of & Why
We start with a tough aluminum alloy. Then, we treat it right—heat treating and precision grinding give it muscle. The result? A sleeve that stands up to the pounding of daily production without wearing down or changing shape. It’s built to last.
Why Our Sleeve Works Better on Your Line
Runs Longer, Saves Money: Forget about constant replacements. Our material and hardening process are chosen for endurance, cutting your downtime and parts costs.
Protects Your Preforms: The inside is polished to a smooth, mirror-like finish. This means no nasty scratches or scuffs on your preforms, leading to far fewer rejects.
Keeps Cycles Quick: A smooth ejection means no sticking or hesitation. Your machine can run at its intended speed, pushing your overall output higher.
It’s a Full Kit, Not Just a Part: We think in systems. You can get the matching take-out tube and cooling core from us too, ensuring everything works together perfectly.
Your Brand, Your Machine: Huayan is our specialty, but we adapt. Whether you run Haitian, Engel, or Arburg, we can engineer a sleeve that fits.
Help When You Need It: Got a question or a unique challenge? Our one-on-one after-sales support is there to find your solution.
How It Fits Into Your Process
After the mold closes and forms the hot preform, the machine’s ejection plate moves forward. Our sleeve, mounted on it, makes clean contact with the preform and pushes it out smoothly. In a coordinated system, the preform is then carried away for controlled cooling. The main goal is a flawless, consistent release every single time.
