New application
New system quickly, safely cleans and wipes pelletizing dies

Our partner Bay Plastics Machinery, specialized in strand pelletizer systems has created a fast, versatile and customizable die wipe for on-demand startup of automatic strand pelletizing lines. Full cycle time is approximately four seconds depending on die width. A 400 mm die face can be wiped in as little as a quarter of a second.

A space-saving design

The unit mounts directly to the die body in a space-saving design that avoids thermally dependent dimension stackups. Available for 45-degree downward-facing, vertical or horizontal strand die plates, the Bay Plastics Machinery die wipe features an angled blade that reduces ‘interrupt’ from the blade crossing die holes — increasing throughput by adding relief clearance once the blade passes. The 38 mm wide brass blade can be used with single- or dual-row strand dies and die face widths between 150 mm and 1,000 mm.

Automated and efficient

Behaving similarly to a manual die wiping action with a handheld scraper, Bay Plastics Machinery’s automated die wipe enables startups at higher throughput rates and eliminates the false starts that often occur from manual wiping. Further efficiency is achieved thanks to the wipe’s low air consumption requirements — meaning no accumulator tanks are required for operation.

Pneumatic control

With an adjustable blade and mounting arm to adjust for optimal preload to the die face, Bay Plastics Machinery’s automated die wipe is pneumatically activated, with speed controllers to fine-tune motions. Two-axis actuation removes the blade from the die face when parked, keeping the blade cool to reduce adhesion with molten polymer, while also enabling access to the die plate. Importantly, the single-direction wipe — moving away from the operator — is guarded for operator safety, the guards enabling heat to pass through.

Flexible solution

Bay Plastics Machinery offers custom mounting options for its automated die wipe, which is available either for standalone operation or integrated into strand line PLCs with customizable electronics.
