4-Cavity Automatic PET Blow Molding Machine
High Speed · Energy Saving · Smart Control
Introduction
In today's competitive PET packaging market, speed, reliability and energy efficiency directly determine profitability. Yushun Machinery, a professional blow molding machine manufacturer based in China, introduces its advanced 4-cavity fully automatic PET blow molding machine. This machine is designed to help bottle producers achieve significantly higher output while lowering operating costs per bottle.
Whether you produce water bottles, edible oil containers, pharmaceutical vials or cosmetic jars, our four-cavity stretch blow molder delivers consistent quality, fast cycle times and intelligent automation – all in a compact footprint.
Why a 4-Cavity Design?
Compared to traditional 2-cavity machines, Yushun's 4-cavity system nearly doubles your output without doubling floor space or energy consumption. With a typical production capacity of 6,500–9,000 bottles per hour (depending on bottle size and preform design), it's the perfect upgrade for growing businesses and established factories seeking higher efficiency.
Advanced Technical Features
- Servo-Driven Stretch System – Ensures precise synchronized stretching across all four cavities, delivering excellent material distribution and low reject rates.
- Energy-Saving Infrared Oven – Independent lamp adjustment per cavity with gold-coated reflectors improves heating efficiency by up to 20%, reducing electricity costs.
- Smart PLC with HMI Touch Screen – Stores up to 200 bottle recipes, real-time production monitoring, fault diagnosis, and remote assistance support.
- Automatic Reject Mechanism – Detects and ejects defective preforms or bottles without stopping production, ensuring only high-quality output reaches downstream.
- Quick Mold Change System – Complete mold change within 30 minutes, minimizing downtime and increasing production flexibility.
- Low Noise Operation – Acoustic enclosure keeps noise levels ≤82 dB, meeting strict workplace safety standards.
