1. Metric High-Precision Cartridge Heater for Injection Molds

Hongtai Metric Cartridge Heaters are engineered specifically for the global plastic injection molding industry. Manufactured to strict DIN and ISO tolerances, these heaters are designed as direct replacements for European standard components (compatible with Hasco, DME, and Parker designs).

Unlike generic heating elements, our injection molding heater features a high-compaction swaged construction that withstands the shock and vibration of rapid mold cycling. We utilize a proprietary high-temperature potting seal at the lead exit, making the heater resistant to moisture and accidental plastic drool, significantly extending the lifespan in harsh molding environments.

2. Key Technical Features

• Standard Metric Sizing: Stock production of 6mm, 8mm, 10mm, 12mm, 16mm, and 20mm diameters.

• Precision Tolerance: Diameter ground to -0.02mm to -0.04mm to ensure a perfect H7 fit in mold platens.

• Contamination Resistant: Special epoxy or silicone potting prevents melted plastic or oil fumes from entering the heater core.

• High Watt Density: Optimized for fast mold heat-up times (up to 20 W/cm²).

• Robust Leads: High-temp fiberglass leads crimped internally for durability.

4. Industrial Applications

This mold heating cartridge is the industry standard for:

• Injection Molds: Heating manifold plates and hot runner nozzles.

• Blow Molding: Heating heads and cut-off knives.

• Extrusion: Die head heating.

• Rubber Molding: Compression mold platens.

5. Why Precision Matters

In injection molding, a loose heater is a failed heater. If a 10mm heater is actually 9.90mm, the 0.1mm air gap acts as an insulator. The heater will run red hot internally to bridge the gap, causing premature burnout.

Hongtai Metric Cartridge Heaters are centerless ground to precise tolerances (-0.02mm), ensuring intimate metal-to-metal contact with the mold tool for maximum heat transfer efficiency and longevity.

6. FAQ

Q: Are these compatible with Hasco standards?

A: Yes. Our metric series follows standard ISO dimensions used by major mold component suppliers. We can match the specific diameter and length codes.

Q: Can you add a thermocouple?

A: Yes. We can build a Type J or Type K thermocouple inside the heater (Grounded or Ungrounded) for precise mold temperature control.

Q: What is the lead time for 500 pcs?

A: For standard metric diameters (6mm-16mm), we have semi-finished tubes in stock. Typical lead time for bulk orders is 7-10 working days.
