Bottle Blowing Machine Mold Components: Preform Sprockets

Chain skipping on high-speed packaging lines causes preforms to overlap and triggers forced shutdowns, directly threatening continuous production stability.

The core of eliminating this anomaly lies in tooth profile modification: compressing the cumulative pitch error on the pitch circle to ±0.02mm, and using involute tooth profile correction to eradicate meshing interference; coupled with a 0.8-1.2mm carburized and quenched layer (HRC 58-62), it counteracts contact fatigue failure, ensuring a smooth acceleration jerk during preform grabbing and eliminating vibrations.

Molds and accessories compatible with blow molding machines, filling machines, and labeling machines of brands such as Sidel, Krones, KHS, and Tetra Pak.

The bore and keyway are machined in a single setup with a keyway symmetry tolerance of 0.015mm, achieving absolute concentric positioning without dial indicator alignment, directly eliminating dynamic balance offset and minimizing replacement downtime.
