Silicone profiles are used for sealing strips, gaskets, and protective edges. They provide excellent weather resistance, elasticity, and non-toxicity. Controlled dimensions and smooth surface before curing are essential. PIPPL precise-plasticization conical twin screws and dual-alloy barrels ensure stable extrusion of complex silicone profiles with high surface quality and dimensional accuracy.
Key Features
• Precise plasticization and temperature control ensure stable extrusion of complex silicone profiles.
• Mirror-finished dual-alloy barrel delivers defect-free surfaces suitable for visible applications.
• High-temperature capability matches silicone curing process requirements.
• Fast die changeover supports multi-section and multi-size production schedules.
• Reliable long-term performance for continuous silicone profile manufacturing.
Product Types
Sealing strips, gaskets, edge protectors, and custom-section silicone profiles in various hardness grades and cross-sections.
