Matching the Machine Family to the Part

Continuous extrusion machines extrude the parison without interruption and are the usual choice for bottles, cans and jerry cans; Chen Way builds them in small, medium and three-layer co-extrusion versions. Accumulator die head machines store molten resin and eject a heavy parison in a single stroke, which suits drums, water tanks, floats and air ducts. The semi-automatic stretch blow molding machine reheats preforms in a rotary infrared oven before stretching and blowing clear PMMA, PS and AS products.

Product dimensions, weight and material usually point to one family, and the auxiliary group then adds rotary cutting, post-cooling, leak testing or drilling where a drum or float line needs it. If the choice is still open, the guide to continuous versus accumulator systems explains how shot size decides it. Send the product drawing and weight with your inquiry to receive a selection review.
