Recently, we have received feedback from customers using compression molding and injection molding processes, with the highest concentration of demand coming from manufacturers of baby silicone products (nipples, teething sticks, feeding utensils, etc.).
Unlike the precision manufacturing sector, these customers focus on three core issues: quality degradation from prolonged baking, discrepancies between domestic and international test results, and overall manufacturing cost accounting.
In response, Betely has conducted targeted validation and fine-tuning of formulations for its post-curing free system, which now offers mature application capabilities for baby product scenarios.
Core Value of Post-curing Free Technology: Eliminate Baking to Solve Multiple Pain Points
Traditional liquid silicone rubber requires 4–8 hours or longer of post-curing after molding, creating significant challenges for baby product manufacturing:
High energy consumption: High electricity costs from prolonged high-temperature baking.
Unstable quality: Impurities in ovens easily adhere to products, and transparent items are prone to uneven yellowing.
Low efficiency: Long baking cycles delay delivery and tie up inventory.
The core advantage of the post-curing free solution: Products meet usage requirements immediately after one-time molding, eliminating post-baking entirely and resolving all the above pain points.
Consistent Testing Standards: Avoid Result Discrepancies at the Source
Domestic and international testing standards for baby silicone products are essentially aligned. The common customer issue of "passing domestic tests but failing international ones" mainly stems from differences in testing equipment precision, sample weight errors, and preprocessing methods. Conventional liquid silicone rubber with incomplete post-curing tends to exceed low-molecular residue limits under stricter testing conditions.
Betely’s post-curing free system controls low-molecular content at the formulation source, with a measured volatile content ≤0.25%. No baking remediation is required, ensuring consistent results across different testing conditions and effectively reducing compliance risks.
Total Cost Advantage: More Competitive Than Conventional Liquid Silicone Rubber
Some manufacturers initially choose conventional liquid silicone rubber for its lower unit price. However, when accounting for oven electricity costs, equipment depreciation, labor and facility expenses, as well as scrap and rework losses from poor baking or failed tests, the total cost becomes significantly higher.
While Betely’s post-curing free solution may not have the lowest raw material cost, it delivers a lower overall manufacturing cost and more predictable production schedules.
Customization Capability: Flexible Adaptation to Solve Practical Process Challenges
Variations in customer molds, molding processes and product wall thickness often lead to issues like difficult demolding, air entrapment and mismatched curing cycles. Betely’s post-curing free system supports tailored solutions: adjustable curing time and temperature, optimized demolding performance, and formulation fine-tuning aligned with mold designs to resolve air entrapment.
Unlike some international brands with rigid formulations and long adjustment cycles, Betely offers more flexible responses and efficient modifications.
Applicable Product Types
Verified and stably supplied baby product applications include:
Nipples: High transparency, soft texture and odorless
Teething sticks: Tear and bite resistant with moderate hardness
Feeding utensils: Spoon heads, bowl rims, straws and other accessories
Material hardness ranges from 20 to 70 Shore A, with mechanical properties meeting the requirements for oral-contact products.
Post-curing free technology is not new, but its systematic application in baby silicone products—truly addressing core issues like baking-induced yellowing, testing discrepancies and cost accounting—requires coordinated validation of formulations and processes.
Betely boasts a mature product portfolio and robust customization capabilities. Interested customers are welcome to contact our technical sales team for sample testing or process evaluation.
