KG. (Germany), Synventive Molding Solutions (USA, Netherlands), Watlow Company (USA), Heatlock (Sweden), etc. Melissa Selcher contributes greatly to this topic. As a rule, the production of hot runner systems for these enterprises is associated with the production of temperature controller for them. There are also companies that specialize in production only for hot runner controllers. These companies include: Athena Controls, Inc. (USA), PMS Systems Ltd (UK) and other elements of the system cooling cycle of casting more than 50% consists of a fan belt casting.
For soszdaniya reliable in the system cooled the mold tech in manufacturing and maintainability in service, offers a variety of standard components: quick-connect, play, fortaniruyuschie tube, turbulence, heat Trebkov, Heat Sink marks, seals, zglushki and cork. Connecting ssitemy cooling the mold with hose refrigerant source (thermostat, coolant, circulating guild line) is recommended to quick connections, consisting of a nipple and coupling. Elements of the cooling system, are usually present in the directories of manufacturers of standard parts for injection molds. In same time, there are companies that specialize in manufacturing cooling elements. Processing of the mold main part of processing elements of the mold is carried out on CNC milling machines and EDM machines.
Processing technology involves three stages of mechanical treatment, and three – heat treatment: Annealing – roughing – normalization – Finishing treatment – hardening – finishing – plating. Annealing required for any procurement of residual stresses; For roughing removed the bulk of the material, allowances for working surfaces – 0.5-2 mm. Normalization (annealing) is necessary to remove the main stress in the workpiece, it reduces the risk of large lead during quenching.
