High-Precision Extrusion Control

GYF achieves stable mass production of silicone extruded products with complex cross-sections, high consistency, and low tolerances through an independent process control system and intelligent extrusion production platform. We not only ensure product dimensional accuracy but also maintain material property homogeneity during continuous extrusion, delivering high stability and reliability.

Precision Molds and Cross-Section Control

We independently design and manufacture extrusion molds to achieve highly stable flow channels, uniform pressure, and precise cross-section control. Key parameters such as mold flow channels and die shrinkage rates are adjusted according to product structural requirements. These molds are suitable for complex geometric cross-sections, special functional sealing strips, and guide rail-type extruded components. The typical tolerance control range is ±0.05mm (depending on product structure).

Intelligent Extrusion Parameter Control System

Real-time monitoring of key process parameters is implemented through an automated control platform, including temperature, pressure, screw speed, material viscosity, and curing rate. Automatic compensation for fluctuations ensures stable extrusion speed and uniform material density, guaranteeing consistency and low defect rates in continuous production with a batch consistency of ≥98%.

Synchronous Control of Material Rheology and Curing

Extrusion temperature zones are adjusted in coordination with material viscosity, curing curves, and mold structures to match curing speed with extrusion speed. This avoids deformation, stretching, and cross-sectional shrinkage. Parameter customization is available for different formulas (flame-retardant, conductive, food-grade, medical-grade, etc.), ensuring high-precision shape retention without deformation or cracking.

Online Inspection and Visual Monitoring

Equipped with online dimensional inspection, laser thickness measurement, and visual defect identification systems, it can detect defects such as bubbles, material shortages, surface particles, and cross-sectional deviations. Data is transmitted in real-time, allowing immediate adjustment of extrusion parameters with a real-time correction accuracy of ≥98% for appearance inspection.

Continuous Extrusion + Post-Vulcanization

After extrusion, online heat setting, post-vulcanization, and surface treatment can be performed to remove volatile substances, improve mechanical properties, and ensure safety and odorlessness. This process is especially suitable for food-grade, medical-grade, and industrial high-temperature silicone products, guaranteeing high purity, aging resistance, and long-term stability.
