CROWN Machine has introduced two game changing pieces of equipment! The CROWN Screw Extractor and the CROWN Element Stripper. Call or email for a price quote!
Pelletizer Die Design
Crown's no-freeze die keeps pellets perfect. The newly developed underwater pelletizing dies from this provider of equipment for compounding, plastics recycling, pipe extrusion, profile extrusion and sheet extrusion, eliminate die-hole freeze off.
Stainless Ceramic Sandwich
New "Anti-Freeze" die face for underwater pelletizers from Crown/CDL Technology Inc., Addison, Ill., has a 0.200-in. titanium carbide/stainless-steel surface layer braised onto 0.100 in. of pure zirconium ceramic, which is in turn braised onto the stainless-steel die body.
The new CROWN Underwater Pelletizing system provides advantages that surpass those of any competitive pelletizer on the market today.
CROWN Biaxial Orientation Systems (BOPS)
The production of biaxially-oriented PP, PET, PS, PA, etc. film is a continuous process. In most cases it is a coextrusion process, where several single and/or twin screw extruders are involved. Usually the base polymer and additives are fed continuously into a single screw extruder or twin screw extruder. The melt that passes directly inline via the usual process for cast film, then transfers to longitudinal and transverse stretching elements.
Film passes through the CROWN MDO and enters the CROWN TDO, where it is stretched. This forces the molecular structure of the film to line up so that it is strengthened in both tensile and impact forces. During the CROWN TDO tentering frame process, the polymer chains are aligned perpendicularly to the MDO axis. Medium or heavy-duty center pull clips, grip the sheet on either side and convey it through an IR oven as the sheet stretches.
With over 40 years of experience in the plastics industry, CROWN Machine is the right choice for pattented designs, innovative processing technology, and strong engineering support to transform project concepts into production.
