Frequently Asked Questions (FAQ)
- 1. What type of steel is S136, and why is it used for food cap molds?
- S136 is a premium stainless mold steel with high corrosion resistance, excellent polishability, and good hardness (HRC 48–52 after heat treatment). It is ideal for food contact applications because it resists rust and can be polished to a mirror finish, ensuring easy release and hygiene.
- 2. Can I use this mold for other materials besides PP?
- This mold is optimized for PP, but it can be adapted for other resins (e.g., PE, PET) with minor modifications to the cooling and gate design. Please consult our engineers for feasibility.
- 3. What is the typical delivery lead time for a 1×24 cavity mold?
- Standard lead time is 25–35 days after design approval and deposit. Customized molds may require 35–45 days. We offer expedited scheduling for urgent orders.
- 4. How do you ensure the mold achieves 300,000 shots?
- We combine high-quality S136 steel, precise heat treatment, and robust structural design. The mold is tested under production conditions before shipment, and we provide recommended maintenance guidelines to maximize its lifespan.
- 5. Do you offer mold try-outs before shipping?
- Yes, we conduct trial runs at our facility using your specified resin (or a similar grade). A trial report with sample photos and measurement data is provided for your approval.
- 6. Can I get a hot runner system for this mold?
- Absolutely. Hot runner systems (e.g., from YUDO, HASCO, or INCOE) are available as an option. This can further reduce cycle time and scrap rate. Please specify during quotation.
- 7. What is the minimum order quantity (MOQ) for OEM molds?
- We accept single mold orders. For custom molds, a design deposit is required. There is no strict MOQ on the number of molds, but volume discounts are available for multiple sets.
- 8. How do I maintain the mold to achieve 300,000 shots securely?
- We provide a detailed maintenance manual. Key steps include: regular cleaning of cooling channels, applying anti-rust spray during storage, inspecting moving parts, and replacing wear components (e.g., ejector pins) after 100,000–150,000 shots.
Note: All specifications and features mentioned above are based on standard configurations. Custom requirements are welcome and will be evaluated individually.
