When a manifold is hanging from a hoist, the nozzles could fall, so technicians should cover the tips to protect them from damage. The clean solution for your injection molding tool. Standardized system components allow time and cost savings in the design, manufacture, assembly and maintenance of the injection mold High-precision and repeatable position of the thread cores (<0,01mm) New drive concept simpli es the tool design and avoids drive in uences on the thread cores High process reliability Process monitoring by servo control unit Phone: +49 6062 80933-0 Fax: +49 6062 80933-33 info@i-mold.com www.i-mold.com i-mold GmbH & Co.

With some manifold systems, this common practice requires heating up the manifold and bridge to about °F so that the plastic "spike" that forms between them breaks more easily. Other systems have free-floating nozzles instead of nozzles that are bolted into their respective plate loca- tions. The cold "spike" pulls the nozzles out when the technician removes the manifold. The spike also can fall and damage the tips. As technicians remove the manifold, it is imperative that they use short sections of rubber hose to protect the tips. These manifold designs add extra labor hours and increase the risk of damage to manifold components. Repair shops with more skill are mak- ing simple modiƒications to manifold system designs to promote more FOR MORE INFORMATION MoldTrax moldtrax.com 419-281-0790 steve@moldtrax.com frequent cleanings and to lessen the chance of expensive component replacement. However, most shops will not entertain these types of modiƒication and struggle to perform PM on a manifold when it is long overdue. Others are stuck with poorly designed systems that wreak havoc on production schedules. As hot runners continue to grow in popularity, technicians in our classes who run and maintain these systems on a daily basis hope that designers strongly con- sider more maintenance-friendly manifold designs to ease maintenance, prolong manifold life and meet production requirements.
