Custom Blow Molding

Extrusion Blow Molding commonly referred to as EBM, is a blow molding method where plastic is melted and extruded into a hollow tube. This tube then gets enclosed into a cold metal mold and air is blown into the tube inflating it into the shape of the hollow bottle, container, part. After the plastic has cooled off, the mold is then opened and the plastic is ejected.

• Continuous Extrusion – At Flexcraft we use state of the art shuttle technology which provides the ultimate flexibility for blow molding both low volume custom jobs and high-volume programs on the same machines. Our machines are equipped with servo driven part takeout, deflashing, and leak detection systems, providing highly efficient, automatic production of custom bottles, containers, and more. Our capabilities include working with materials like PETG, HDPE, PCR, LDPE, PP, PC, Styrolux & more. Mold Cavitation is 1-12.
• Accumulator Head – Accumulator head blow molding machines are required for large part blow molding. With accumulator head machines, the screw conveys a specific volume of material into the head of the machine to the desired shot size. Once that shot size is met, a “plunger” inside the head pushes the material through the die so a parison large enough to form a part can be extruded from the head without gravity pulling it to the floor.
