There’s an industry saying……make a bad preform – make a bad bottle. It’s inefficient and costly to blow defective preforms into bottles that will be rejected anyway, so it pays to remove them from the process as early as possible. Pressco offers a family of scalable modules that provide comprehensive inspection of preforms across all of the critical regions of interest.These modules can be integrated inside stretch blowforming machines such as Sidel, Krones and KHS.
