Wilmington Machinery, a manufacturer of high speed rotary co extrusion blow moulding systems and structural foam injection moulding machinery, is breaking the world speed record in rotary extrusion blow moulding bottle production. Innovative new dual parison technology is enabling remarkable production rates from 800 bottles per minute to 1200 bottles per minute, believed to be one of the fasted commercially available.
Wilmington recently shipped the first dual parison Small Bottle (SB) rotary extrusion blow moulding line producing 80 ml HDPE bottles at a rate of 800 per minute, operating at the very fast cycle time of 10 RPM (6 seconds). The MSB40 Dual Parison machine has 40 stations, 4" extruder and Wilmington's uniquely designed high-output dual parison die head. The turnkey system includes moulds, bottle conveying and high-speed rotary spin trimmer. It produces weight variation of less than +/- 0.05 grams, yielding excellent material distribution.
The system is the first of several new dual parison models that Wilmington plans to build. All models are designed to be energy efficient, economical and save floor space. Coming up next is their model MSB60 DP which can produce 80 ml lightweight type bottles at the blazing speed of 1200 bottles per minute.
