New or Used Blow Molding Machine? How to Decide

Compare the complete investment

A lower purchase price can make used equipment attractive. Include refurbishment, compatible molds, transport, installation and training in the comparison. Check parts availability and technical support before committing to an older model.

Inspect the machine in production

Request its age, operating hours and maintenance history. Inspect the screw and barrel, die head, hydraulics, heaters and controls. A trial with a representative container helps reveal inconsistent weight, wall distribution or cycle performance. Confirm that the mold envelope, head and clamping arrangement fit your product.

Choose around your production plan

Used equipment may suit a short project or a team equipped to rebuild it. New equipment allows the configuration and tooling to be specified together. Compare measured energy use under agreed trial conditions and establish who will commission and support the line.
