Ordering a custom injection mold is a big decision for any U.S. food packaging company. The mold you choose will determine your production speed, product quality, and overall costs for years to come. That’s why you can’t just look at price—you need to check the details before placing an order.

Here’s a practical checklist that will help you avoid costly mistakes.

1. What Material Will the Mold Be Used For?

Different resins behave differently. PP, PS, and biodegradable rice husk composites all have unique flow and cooling characteristics.

✅ Before ordering, confirm that your mold supplier has experience with the exact material you plan to use. For example:

• Thin-wall PP molds for lightweight containers

• PS molds for clear packaging

• Rice husk molds for eco-friendly products

At Baolin Mould, we always run mold flow analysis to ensure material compatibility.

2. What Steel Grade Will Be Used?

Mold durability largely depends on the steel quality. Low-grade steel may save money upfront but often leads to wear and costly repairs later.

💡 Tip: For high-volume packaging production, ask for H13 or S136 hardened steel.

3. Is Mold Flow Analysis Included?

This is one of the most overlooked steps. Mold flow simulation helps identify issues like air traps, weld lines, or uneven filling before cutting steel.

If your supplier skips this step, you’re basically gambling with your investment.

4. How Many Cavities Do You Need?

The number of cavities directly affects output and cycle time. Multi-cavity molds (e.g., 4, 8, 16 cavities) are ideal for U.S. food packaging companies that require high-volume production.

However, more cavities = higher upfront cost. The key is to balance your production needs with your budget.

5. What About Cooling and Ejection Systems?

Cooling accounts for up to 70% of cycle time. Poor cooling design = slower production and higher costs.

Also, check if your mold has a reliable ejection system. Thin-wall parts are delicate and require smooth ejection to avoid cracking.

6. What Is the Lead Time?

Delays in mold delivery can stall your production schedule. Always clarify:

• Design phase timeline

• Manufacturing phase timeline

• Trial and shipping schedule

At Baolin Mould, we provide a clear project timeline and keep clients updated at every step.

7. What After-Sales Support Is Offered?

Even the best mold may need adjustments after shipping. Reliable suppliers provide:

• Spare parts

• Online troubleshooting

• Maintenance guidelines

This support can save you thousands of dollars over the mold’s lifetime.
