Production Workflow
How was the silicone shape sorter produced and inspected?
Open the complete silicone shape sorter process guide
Rubber Mixing & Pre-Preparation
Blend food-grade silicone with food-safe color pigment, cut into weighed portions to guarantee consistent hardness & color across batches.
Mould Preheating
Clean dedicated precision puzzle mould, preheat on vulcanizing machine at constant temperature for stable forming, strictly control dimension accuracy of holes and shape inserts.
Loading & Mould Closing
Load weighted silicone into cavity, close mould and conduct repeated de-gassing cycles to avoid defects like air bubbles, short-shots and dimension deviation.
High-Temperature Vulcanization
Vulcanize under constant heat & pressure to cross-link silicone material into a solid one-piece part, tough enough for pulling, dropping and baby biting.
Demoulding & Cooling
Take out puzzle base and shape inserts after mould opening, air-cool naturally to avoid deformation and maintain precise matching tolerance.
Post-Processing & Quality Inspection
Trim flashing, second high-temperature baking for odor removal, sanitize products. Inspect appearance, tensile strength, dimensional tolerance and safety performance, then pack in sterile condition before warehouse storage, fully compliant with children’s toy safety requirements.
