Injection Molding Heater Factory

Frequently Asked Questions

• Q: Why do my injection molding barrel heaters keep failing?

• A: Common causes include plastic melt leakage causing a short circuit, poor fit leading to hot spots, or voltage spikes. We can help diagnose the issue and suggest more robust heater designs.

• Q: What is the best heater for a hot runner manifold?

• A: High-density, high-wattage cartridge heaters with a swaged construction are the best choice. They provide excellent heat transfer and are built to withstand high pressures.

• Q: Can you supply heaters that are compatible with my specific machine brand (e.g., Engel, Arburg)?

• A: Yes, we can manufacture heaters to the exact specifications of any machine brand. Please provide the part number or dimensions of the original heater.

• Q: What is the advantage of using a cast-in heater for a mold?

• A: Cast-in heaters can be designed to conform to the complex shape of a mold, providing highly uniform and efficient heating directly where it's needed, improving part quality and cycle time.

• Q: How do I choose between a mica and a ceramic band heater for the barrel?

• A: The choice depends on your processing temperature. Use mica for temperatures up to 450℃. For higher temperatures required for many engineering plastics, ceramic bands are necessary.

• Q: Do you offer nozzle heaters with integrated thermocouples?

• A: Yes, we offer a variety of nozzle heater styles, including those with an integrated thermocouple for the most accurate temperature control at the nozzle tip.

• Q: What is the typical lead time for custom hot runner heaters?

• A: For custom hot runner heaters, the lead time is typically 3-4 weeks. We also offer an expedited service for urgent needs.

• Q: Can you provide technical support for heater selection?

• A: Absolutely. Our technical team has extensive experience with injection molding and can work with you to select the optimal heating solution for your application.
