Among the hot runner solutions that Inglass‘ HRSflow brand will showcase is new nozzles in its Multitech MTR range, designed for both thin- and thick-wall injection molding processes with multi-cavity molds. The focus is on high cavity numbers, short cycle times, homogeneous balancing and rapid color changes, the company says.
The nozzles are available in three specifications: MTR-T, MTR-M and MTR-S. Nozzle tips on all three offer high resistance to wear and tear.
The MTR-T is specifically designed for injection molding of large containers with wall thicknesses from 0.45 mm and a flow length-to-wall-thickness ratio to 350. It enables injection pressures to 2,200 bar and high melt throughputs to 180 g/s. Its high process stability also makes this nozzle suitable for decorative injection molding using in-mold labeling. The MTR-M nozzle is suited for injection molding of polyesters to produce high-gloss parts, while the MTR-S model is geared specifically for molding DuPont’s Surlyn ionomer. Both nozzles are capable of wall thicknesses of 20 mm and more.
