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?

Reject mass failures! How to control the quality of silicone spatulas

Attention, bosses engaged in kitchenware wholesale and brand OEM! When purchasing silicone spatulas in bulk, you might worry about inconsistent quality. Once issues like yellowing, deformation, or peculiar smells arise, it will not only cost you money but also damage your brand reputation. In fact, mastering 5 key control links can steadily ensure the quality of bulk products!

First, strictly control raw material selection! You must use food-grade silicone raw materials that meet the GB4806.11 standard, ask for raw material testing reports, and eliminate recycled or inferior materials. Before mass production, conduct small-scale trials to test the raw materials’ resistance to high and low temperatures (-40℃~230℃) and anti-yellowing performance, so as to avoid quality hazards from the source.

Second, strictly control the production process! Vulcanization temperature and time should be standardized to prevent under-vulcanization or over-vulcanization, which can cause uneven hardness and easy breakage of silicone spatulas. At the same time, assign on-line quality inspectors to monitor the molding process in real-time and promptly remove unqualified semi-finished products with edge burrs, bubbles, etc.

Third, strengthen finished product testing! Conduct sampling inspections at 5%~10% of the batch quantity, focusing on checking appearance (no scratches, uniform coloring), performance (stretch rebound, high-temperature cooking resistance), and safety indicators (heavy metals, harmful substance precipitation). Only products that pass the inspection can be stored in the warehouse, and all unqualified batches must be reworked.

Fourth, standardize warehousing and logistics! Finished products need to be stored in a cool and dry warehouse to avoid accelerated aging caused by direct sunlight and high-temperature humid environments. In the logistics link, do a good job in protective packaging to prevent extrusion deformation during transportation, ensuring that the silicone spatulas delivered to customers are intact.
