1) Temperature Stability Directly Affects Bonding QualityHot melt adhesives are temperature-sensitive. If the hose heating is uneven or heat retention is poor, it can cause:Inconsistent adhesive flowStringing or drippingUneven bead sizeFluctuating bond strengthThat’s why more manufacturers now look
1) Sealant / Adhesive Dispensing LinesCommon pain: material build-up, sticking, deposits that cause flow drift; viscosity changes with temperature.Upgrade direction: low-adhesion liners, smoother inner surfaces, optimized ID tolerance, and (when needed) temperature-control options (design-dependent)
The heating hose provides stable heating. The maximum working pressure is up to 1000 psi. RTD sensors of Ni120 or Pt100 are optional. Wear-resistant throat pipeWear-resistant hot melt adhesive throat pipe, covered and protected by corrugat
