Frequently Asked Questions (FAQ)
-
What is the typical mold life for a 1*16 flip-top cap mold made of hardened S136?
Our hardened S136 molds are designed to last for over 1,000,000 injection cycles under standard production conditions (using PP or PE materials). With proper maintenance, the mold can often exceed this figure. -
Can you produce molds for special flip-top cap designs, such as those with integrated tamper-evident rings?
Yes, we offer full customization. Our engineering team can incorporate tamper-evident features, custom hinge designs, and different closure mechanisms based on your drawings or samples. -
What materials can be used with this mold?
The mold is compatible with most common thermoplastics used for flip-top caps, including PP, HDPE, LDPE, and certain engineering plastics. Please advise your material choice for optimal gate and cooling design. -
What is the lead time for a new flip-top cap injection mold?
Typical lead time for a 1*16 cavity hardened S136 mold is 25-45 working days, depending on design complexity and workload. Faster delivery may be arranged for urgent projects. -
Do you provide mold trial and sample parts before shipment?
Absolutely. We offer mold trial services at our facility. Samples of the flip-top caps will be provided for your approval before shipment. We can also send videos or photos for remote inspection. -
What is the minimum order quantity (MOQ) for this service?
As a custom mold manufacturer, our MOQ is 1 set of mold. However, we recommend ordering at least 1 mold to start. For injection molding production runs, MOQ is typically 10,000 pieces per order, but can be negotiated. -
Is your hardened S136 steel sourced from a certified supplier?
Yes, we use only premium-grade S136 steel from well-known mills, with material certificates available upon request. The steel undergoes ESR (Electro-Slag Remelting) for enhanced purity and uniformity. -
