In high-volume packaging industries, consistency is everything. One imperfect cap can disrupt sealing performance, brand image, and production efficiency. Our Multi-cavity Flip-top Molds are engineered to eliminate these risks by delivering stable, repeatable, and high-precision molding results across every cycle.
Designed for cosmetic, personal care, and edible oil applications, these molds combine advanced cavity balance technology with durable steel construction to ensure smooth production even under demanding conditions. The tactile feel of each molded cap—clean edges, smooth hinge movement, and satisfying closure—reflects the precision behind every cavity.
From the first shot to the millionth, this mold helps manufacturers maintain product integrity, reduce waste, and accelerate production without compromising quality.
Although cosmetic flip-top lids and edible oil flip-top lids both fall under flip-top mold categories, the specific solutions can be flexibly adjusted based on requirements. The key differences lie in cavity layout, insert materials, and hot runner configurations, with the final plan matching costs to the customer’s needs
The number of cavities in flip-top molds can be designed as "multi-cavity per insert": for example, 2 cavities per insert, 4 cavities per insert, or even 8 cavities integrated into a single insert; denser layouts (16-48 cavities in one insert) are also feasible. The more concentrated the cavities and the larger the insert size, the higher the mold space utilization—but processing difficulty and costs also increase accordingly. Inserts with fewer cavities have lower individual processing costs but lower overall mold efficiency, while multi-cavity integrated inserts are the opposite.
Insert materials can be matched to the customer’s budget and product requirements: options include H13 steel (hardness 48-52HRC, cost-effective) or stainless steel materials (e.g., S136, 632, M33, 622, hardness 47-50HRC, corrosion-resistant and good for polishing). Different materials vary significantly in processing costs and service life, so selections should align with the product’s application scenario (e.g., S136 for high-gloss cosmetic lids, H13 for wear-resistant edible oil lids).
Hot runners can be open-type (low cost, suitable for simple products) or valve-gated (precise sealing, less runner residue, higher cost); for brands, both imported options (e.g., Husky, Yudo) and domestic hot runner brands are available. Our mold factory is responsible for assembling the mold with the customer-specified hot runner brand, ensuring the system matches the mold structure.
