【Question 1】How do I know if this model of PET stretch blow molder is suitable for me?
Answer: LS8 has a cavity pitch of 114.3mm in molding section. It allows bigger bottles but will also consume slightly longer time over preform infeeding (from oven to molding) and bottles outfeeding due to longer motion distance. When you need more production for bigger bottles like 1Liter, 1.5Liter and 2Liter, this model will be better than other models with only 76.2mm cavity pitch! If your production for such bigger bottles is secondary, other models with 76.2mm cavity pitch will be better!
【Question 2】Why can such blow molder make better quality PET bottles?
Answer: The preform heating is continuous so all preforms can be precisely heated equally, avoiding any bottle quality problems resulted from uneven preform heating (overheating or inadequate heating etc.); additionally, it allows higher blowing pressure and faster stretching, resulting in better crystalization and bottle formation. The PET molecular chains will be better aligned with higher blowing pressure and faster stretching!
【Question 3】How much compressed air do I need to work the LS8 stretch blow molder?
Answer: First of all, confirm the biggest bottle you want to produce by the LS8 and also the maximum production capacity according to your bottle shape and preform weight & design. And then follow this equation: required compressed air (m3/min.) = {[Biggest bottle volume (Liter) + 0.1(Liter)]* BPH * 30 (Bar) * 1.3}/60 (Minutes) (when the altitude is above 1000meters, the required compressed air will increase 10% every 1000meters). E.g. the biggest bottle you want to produce is 2liter and you expect to have 12000BPH speed according to your bottle shape and preform grams, then the compressors you need will be （2Liter + 0.1Liter) * 12000BPH *30Bar *1.3/60 = 16.38m3/min. To save investment, a 16m3/min. 40bar oil free air compressor will be fine; to be safe for maximized production, 18m3/min. one will be better. If the machine operation place altitude is 2000meters, then 16.38m3/min. *1.2 = 19.65m3/min : a 20m3/min. 40bar oil free air compressor will be better.
【Question 4】How many containers do I need for the transportation?
Answer: one LS8 stretch blow molder require a 40HQ to be loaded and only little space for moulds and chillers. Air compressors, air purification system and water cooling tower etc. will need additional containers.
