This ensures that the materials not only meet usage requirements but also are safe, compliant, and stable for long-term use.
04. Synergistic Optimization of Materials + Processes
Different silicone materials have different fluidity, curing reactions, and molding characteristics. GYF not only customizes materials but also synchronously optimizes molding process parameters (pressure, temperature, curing curve, exhaust design, etc.) according to material properties to ensure:
More stable molding quality
Fewer process defects
Longer mold service life
Higher production efficiency
Precision Molds + Complex Structure Molding
In high-demand silicone manufacturing, mold quality determines molding quality, and mold engineering capabilities define product limits. As a high-end silicone manufacturing enterprise with independent mold R&D and production capabilities, GYF achieves reliable molding of products ranging from microstructures to multi-material composites through precision mold technology and rich experience in complex structure molding.
01. In-House Mold Center with High-Precision Processing Capabilities
GYF has a professional mold department, boasting comprehensive capabilities from structural design to precision processing: CNC machining, EDM (Electrical Discharge Machining), 5-axis machining, and mirror polishing processes. It possesses mold processing capacity with a tolerance level of ±0.01 mm and a monthly mold development output of 30–100 sets. The department provides mold testing optimization, structural improvement, rapid maintenance, and mold life management, enabling quick response to project development cycles and stable support for mass production needs.
