The cartridge heater is the main feature! The clearance between the hole and the heater is the key point.
In mold heating, holes are drilled in the mold using a gun drill, and a cartridge heater is inserted; however, the clearance between the hole and the heater is the key point. This is because the presence of air, which has poor thermal efficiency, in the clearance hinders heat conduction. Reaming is used for the hole, and centerless grinding is applied to the heater to improve precision, but cost becomes an issue. 【Product Handling Case Study (Packaging Machine Manufacturer)】 ■Issues - Due to the design where the mold moves during the sealing of the packaging, the lead wires often break at the junction with the cartridge heater. ■Solution - Adopted a swaged-in method for the connection between the heater and the lead wires inside the heater. - Used smooth fluororesin wires for the lead wires to prevent breakage. *For more details, please refer to the related link page or feel free to contact us.
