This batch includes 7 Cartridge heaters, with a strictly controlled tube diameter of Φ12mm and a customized length of 780mm to meet the precise heating needs of inserts in small injection molds. The product features a 307 stainless steel tube filled with high-density insulating magnesium powder, ensuring uniform heating without local overheating and preventing product flash or deformation caused by uneven mold temperature. The lead wire is a 200mm PVC insulated wire, adapting to the mold's wiring layout and enabling installation without additional extension. During production, each heater undergoes a 60-minute power-on test to verify heating stability and circuit continuity, with dimensional deviation controlled within ±0.02mm to ensure a perfect fit with the mold slots. Currently, the products have been vacuum-packaged with desiccants for moisture protection and will be delivered to the mold factory for use in the home appliance shell injection production line. As a regular single-ended heater, this product has become a common choice for small injection mold heating due to its high adaptability and stable performance, and we will continue to optimize tube diameter and length parameters according to customer needs.
