🔥 TPV Coating Die: Traditional Pain Points vs. DEKUMA’s Upgrade
Low vacuum near the coating point can lead to weak adhesion, low peel strength, delamination, cracking and material waste in TPV-coated pipes.
DEKUMA adds a guide sleeve to improve sealing near the coating point. This raises the vacuum level there, helping the TPV layer bond more firmly to the inner pipe and improving peel strength.
❌ Traditional Die
• Low vacuum near the coating point
• Poor coating adhesion
• Risk of delamination and cracking
✅ DEKUMA Upgrade
• Added guide sleeve
• Higher vacuum near the coating point
• Improved peel strength
Better die design helps improve coating quality in TPV pipe production.
