Milk PET bottle making machine semi automatic MS-5L2 is suitable for all PET products with capacity within 2L to 5litre, such as Edible oil bottle, water bottle, mineral water bucket, can, lantern and so on. The biggest characteristic of 5L stretch blow molding machine is that it can meet the requirements of large capacity.

Dimension & Weight
1.The air system consist by two parts: Pneumatic action part(low pressure) and bottle blowing part(high pressure), with separate air tank, which is safe design.
2.Can make PET bottles from 0.1L to 5L (2 cavity).
3.Defect rate of finished bottle is less than 0.2%.

Solenoid Valves: Airtac
Pneumatic cylinder: FESTO / Airtac/ SMC
Breakers and contactors: SCHNEIDER or CHINT
Sensor: OMRON or Airtac
Inverter: ABB or DELIXI
Company vision: Make blowing simpler.
Industry Tips (Trouble shooting during PET Blow Molding and Solution)
Light Base Weight
Description: Base under desired weight.
1.Pre-blow pressure too high.
2.Pre-blow too early.
3.Poor heating profile resulting in poor distribution of material, insufficient stretching of the body or shoulder.
4.If only one cavity then flow restrictor may be open too many turns.
5.Faulty non-return valve, allowing the high-pressure air to pass into next station at pre-blow stage.
1.Reduce pre-blow pressure.
2.Make pre-blow later.
3.Reduce heat near the base of the preform until pearlescence occurs, then increase heat to the shoulder and/or body. Repeat until base weight is correct.
4.If only one cavity is affected then close flow restrictor to decrease flow of pre-blow air.
5.Move oven banks closer to the preform to improve penetration. Replace non-return valve at preceding station.
