Case Details
Recently, TYhori's technical support team received an inquiry from a client.
The client described a specific production issue: the regular medium-temperature white hot melt adhesive they were using had turned from yellow to deep black after approximately two days of continuous operation in the glue pot, with severe charring on the surface, while the adhesive at the bottom of the pot remained normal.
The client specifically noted that this adhesive was not a TYhori product and that their end-user had reported similar occurrences even with a well-known German brand adhesive.
The client was deeply perplexed and sought to clarify the root cause from a technical perspective—was this an issue with the adhesive itself or the equipment operation?
Faced with this complex operational consultation involving a non-TYhori product, the team did not avoid the issue.
Instead, upholding a professional attitude of "solving common industry problems," they promptly provided a precise analysis.
After carefully listening to the client's description of the glue pot temperature being set at 150°C and the "low adhesive volume," the technical expert immediately identified the key culprit: insufficient adhesive load in the pot was the direct cause of localized overheating and oxidation.
The expert explained that when the adhesive level in the pot is too low, the heat generated by the heating elements cannot be adequately absorbed and conducted by a sufficient amount of adhesive, causing localized temperatures to far exceed the set point.
This leads to continuous high-temperature thermal oxidation and carbonization of the adhesive, resulting in the formation of a charred, "burned" layer.
Based on this diagnosis, the TYhori team offered a clear, direct, and actionable solution: it is essential to ensure the adhesive load in the pot is maintained at least two-thirds full during operation.
This recommendation was not general advice but was rooted in a profound understanding of the thermodynamic principles of hot melt adhesive equipment.
An adequate adhesive volume ensures even heat distribution and stable transfer, effectively preventing localized overheating and thereby guaranteeing the adhesive's thermal stability and color consistency within acceptable tolerances.
Although this consultation stemmed from a third-party product issue, it fully demonstrated the TYhori team's professional spirit of "transcending brand boundaries" and technical capability of "focusing on the essence of the problem."
The team did not limit itself to promoting its own products but started from fundamental principles, pinpointed a critical oversight in the client's production process, and provided immediately actionable corrective measures.
This approach, centered on the client's actual operational efficiency and actively sharing professional knowledge, is the very foundation upon which TYhori builds market trust and establishes its image as a reliable technical partner.
Through each specific and detailed technical interaction, TYhori continuously reinforces its core value as a trusted problem-solver in the edge banding and bonding field.
