Hot-runner system targets small parts.A new mini hot-runner system for direct injection of small to micro-sized parts is new from Hasco America Inc., Arden, N.C Its new H7000 can handle a total shot weight of 20 g and can produce four, eight, or 16 parts per cycle with individual weights from 0.01 to 2 g. The system allows for tip cluster spacing as close as 8 mm. The wear-resistant, highly heat-conductive nozzle An orifice in an inkjet print head through which ink is sprayed onto the paper. Print heads with six thousand or more nozzles are common in today's printers. Nozzle tips screw directly into the manifold manifold In mathematics, a topological space (see topology) with a family of local coordinate systems related to each other by certain classes of coordinate transformations. Manifolds occur in algebraic geometry, differential equations, and classical dynamics. to ensure optimum heat conduction Heat conduction or thermal conduction is the spontaneous transfer of thermal energy through matter, from a region of higher temperature to a region of lower temperature, and hence acts to even out temperature differences. into the gate from a central cartridge heater. Gate diameters can be as small as 0.4 mm. Units have replaceable thermocouples and a sealing technique that eliminates stresses resulting from thermal expansion thermal expansion Increase in volume of a material as its temperature is increased, usually expressed as a fractional change in dimensions per unit temperature change. of the manifold. A version of the system, called H7001, can be used with a newly developed feed bushing on standard mold sizes of 156 x 156 mm and larger. Tel: (828) 650-2600 * PTDirect 452JH |
