A. Brief Introduction 

YCQ-2L-8 is the most stable two-step fully automatic high-speed rotary PET stretch-blowing machines(reheat). The capacity of the products is from 0.25L to 2L. It can blow pet bottles for different use: Carbonated, mineral water, milk, beer, oil, hot filling tea, and other drink packing containers, which is made of plastic of crystalline type, such as PET, PP etc. 
YCQ series has adopted original heating and blowing technics, by which the automatic blowing machine series have achieved in powerful productivity but very reasonable price. 

B. Machine Construction 
B. 1. Preform feeding and loading unit 
The design of the recycling unit prevents the preforms from getting bound up in the unscrambler. The star wheel design of the feeding unit provides the lowest possible changeover times for switching to different perform sizes. 

B. 2. Linear Oven 
A mandrel capable of turning 180 degrees guarantees uniform neck section during the heating. A unique oven ventilation system enables the YCQ series blower to handle various difficult applications easily. 
I. Power saving: Heater is fixed with link of short section(43.8mm), which assures to heat more performs with the same heating length. In this way, it saves electricity of 25%. 
Ii. Water cooling plate: Cooling bottle neck avoid neck deformation during heating. 
Iii. Infrared heat lamps: 
A. Each lamp is individually adjustable; 
B. Lamp gripper is adjustable as angle changes; 
C. Lamp rod is adjustable in length, which is good for bottom heating; 
B. 3. Preform and bottle transfer wheel 
The new YCQ series utilizes a classic double cam telescopic gripper system, this guarantees reliable movement, and easy maintenance. 
B. 4. Molds and Mold Carriers 
The mold carrier utilizes a shell blow mold design; This reduces the changeover time for different blow molds. The Mold carriers accommodate all shell type molds from conventional blow molding machines, this saves time and expense for bottle producer. Moreover, the reliable quick locking system maximizes the performance of the mold carriers. 

B. 5. Blowing Station 
A changeable cam for the stretching curve guider guarantees the form quality for different size bottles. Monobloc blowing valves achieve the fastest and most consistent blowing process possible. Bottle necks are protected during the blowing stage by a specially designed sealing unit.
