Provided dedicated high-temperature grease solution for injection molding workshop, eliminating lubrication failures.

Challenge

Injection molding machine tie bars and mold hot runners operate at 180-300°C, causing severe carbonization and coking of ordinary grease, leading to tie bar scoring, mold precision degradation; grease runoff causing product stains and reduced yield rate.

Solution

Adopted Denuhigh HT-300 high-temperature chain oil and Denuhigh FG-250 high-temperature grease for tie bar lubrication and hot runner systems respectively. Supplemented with standard operating procedures for lubrication point cleaning and reapplication.

Results

Tie bar scoring failures eliminated, mold precision retention improved to 99%, product stain rate reduced from 3.5% to 0.2%, injection molding machine OEE improved by 8%, annual scrap loss savings of 600,000 RMB.
