Worried about mass-produced silicone spatulas getting unglued and needing rework after bulk purchasing? If you’re in kitchenware wholesale or OEM, you must read this! —— Separation of the spatula head from the handle, cracking after high-temperature use, not only leads to concentrated returns from downstream customers but also directly damages the brand reputation. In fact, choosing the right integral molding process and implementing 3 key controls can fundamentally eliminate ungluing and steadily maintain the delivery rate!

First step: Lock in the integral molding process! Abandon the traditional silicone spatula bonding process and adopt high-temperature vulcanization integral molding technology to seamlessly integrate the silicone material with the handle frame, eliminating the hidden danger of ungluing structurally. Before mass production, it is necessary to trial-produce 50-100 samples. After being steamed at 200℃ for 2 hours and subjected to 1000 repeated bending tests, production can proceed only if there is no loosening or ungluing.

Second step: Adaptation of raw materials and processes! Use food-grade silicone that meets the GB4806.11 standard, combined with special bonding additives, to ensure compatibility between the silicone and handle materials (wood, plastic, metal). Control the vulcanization temperature between 160-180℃ and the holding time to the second to avoid weak bonding due to deviations in process parameters.

Third step: Strengthen durability through finished product sampling inspection! Conduct sampling inspections at 15% of the batch. In addition to checking for no burrs on the appearance and meeting size standards, focus on ungluing tensile tests (tensile force ≥50N is considered qualified) and high-temperature working condition simulation tests. Unqualified batches are directly reworked and never flow into downstream channels. Choosing suppliers that support integral molding technology fundamentally reduces the risk of after-sales issues caused by ungluing.

Whether you’re a kitchenware wholesaler, brand OEM factory, or catering supply chain purchaser, worried that mass ungluing of silicone spatulas will affect your business? Click on the online customer service or call directly. We provide high-quality silicone spatulas with integral molding technology in bulk, support verification of inspection reports and small-batch trial orders, helping you purchase with confidence and no after-sales worries!
