Wilmington Machinery MSBW60-DC blow-molding machine

Wilmington Machinery Debuts Dual, Rotary Blow-Molding Machine

The MSBW60-DC blow-molding machine can handle two bottles with different capacities at rates up to 600 bottles per minute.

New blow-molding equipment from Wilmington Machinery can handle two bottles with different capacities at rates up to 600 bottles per minute to match a filling line’s speed. The MSBW60-DC dual, rotary blow-molding machine has common extrusion, die-head, and trimming components and is capable of molding small one- to 10-ounce bottles for single-serve drinks, personal-care products, chemicals, and more.

Features of the new MSBW60-DC blow molding machine include the following:

  • The 60-station, all-electric, single- or dual-cavity wheels operate at the required rate without a mold change. This dramatically reduces setup time from one bottle size to the next by as much as 75%.
  • Quick disconnects for electrical, water, and pneumatic services reduce wheel setup time from hours to a matter of minutes.
  • Trimmer setup time is comparatively quick.
  • Preventive maintenance can be performed on a wheel while it is out of production, reducing time and labor costs while ensuring that setup performs correctly at startup.
  • A unique rail system guides one of the two wheels out of the molding system and guides the other wheel into the molding position.

The MSBW60-DC is currently available in several configurations, including clamping force/bottle size, single or dual parison, one to six layers, radial mold positioning (aka variable pitch), and custom features, as required. The cost of the machine with the dual wheels and two sets of molds is approximately 15 to 20% more than a single wheel with two sets of molds, according to Wilmington Machinery.

If volume needs increase, one or the other wheel can be retrofitted with its own extrusion and trimming equipment, minimizing investment in a second production line.
