Description:
Our premium silicone oil brush—precision-molded via advanced injection technology—is engineered for flawless, uniform oil application in grilling, roasting, and baking. Constructed from FDA-approved, food-grade silicone, it delivers a nonstick surface, exceptional durability, and heat resistance up to 450°F. Leveraging state-of-the-art tooling and in-house mold expertise, we guarantee tight tolerances and repeatable quality. As an ISO-certified OEM partner, we offer fully customizable designs, logos, and packaging, backed by rigorous QC protocols to ensure every brush meets strict performance, hygiene, and safety criteria.

Production Process:
-
Material Selection & Preparation
– Use FDA-compliant, food-grade liquid silicone rubber (LSR) with high-temperature resistance (e.g., 300°F+). Raw material batches undergo certification testing (e.g., LFGB, RoHS) to ensure chemical stability and non-toxicity.
-
Mold Design & Validation
– Precision-machined hardened steel molds with polished cavities to minimize flash and ensure smooth brush surfaces. Mold flow analysis (via software like Moldflow®) optimizes gate placement and cooling channels for uniform curing.
-
LSR Injection Molding
– Fully automated injection molding machines with closed-loop temperature control (180–220°F) inject LSR into molds under high pressure. Critical parameters (shot size, cure time) are validated using scientific molding principles for consistency.
-
Demolding & Post-Curing
– Parts are carefully ejected to avoid deformation. Post-curing in convection ovens (300–400°F for 1–4 hours) enhances thermal stability and eliminates residual volatiles.
-
Deflashing & Surface Finishing
– Automated cryogenic deflashing (using liquid nitrogen) removes micro-burrs. Brush bristles undergo laser trimming for uniform length and flexibility.
-
Cleaning & Sanitization
– Ultrasonic cleaning in deionized water removes contaminants, followed by UV sterilization to meet food-contact hygiene standards.
-
Quality Assurance Testing
– Dimensional checks (CMM for bristle spacing/tolerances), durometer testing (Shore A hardness), and thermal cycling tests (-40°F to 500°F) validate durability. Tensile testers (e.g., Instron) assess bristle tear resistance, while FTIR spectroscopy verifies material integrity.
-
Assembly & Packaging
– Brushes are assembled with heat-resistant handles (if applicable) using food-grade adhesives. Final inspection includes 100% leak testing (oil retention) and packaging in sterile, vacuum-sealed pouches.
