Needle Shut-Off Nozzle - Type TSN The spring actuated machine needle shut-off nozzles type TSN are used in the processing of thermoplastics, principally with low viscosity materials such as: PA, PPS, PE, POM, PP. A shut-off needle is positioned axially inside the nozzle. This is held in the closed position (default position) by spring force.

High-Speed, Thin-Wall Molding Doesn't Need an

Aug 01, 2001 · After the melt was precompressed to 34,825 psi, the mold filled in 60 millisec, compared with 80 millisec using a conventional accumulator-equipped machine and an injection speed of 1000 mm/sec. In addition, variations in part weight with X-Melt were ±0.03%, less than half the ±0.07% achieved with accumulator injection.

Injection Machine Nozzle Tips - IMS Company

IMS precision made nozzle tips are designed from high quality, heat-treated tool steel and are perfect for every-day use in the injection molding shop. The technicians at IMS have worked hard to bring you quality at an affordable price.

K 2001: Nozzles for every occasion and more

Called Rapid Shot (also known as Z 3500), the nozzle carries a gate configuration and melt chamber that can reportedly be adapted to any application. The nozzle can also be used for multicavity hot runner molds. Nozzle tips, heaters, and thermocouples reportedly can all be exchanged in the injection molding machine.

Needle and bolt shut-off nozzles for the injection molding

For the injection molding process a machine nozzle was developed, which is characterized by high mixing capacity with low pressure loss. The durable mixing elements are corrosion resistant and can be used also for abrasive media (until approx. 30% glass fiber portion).

Needle shut-off nozzle for an injection molding machine

The needle shut-off nozzle is provided in a housing for delivering polymer melt to an injection molding machine or an injection molding tool. The nozzle is mounted in a channel of the housing for a flow of the polymer melt, a nozzle at an outlet of the channel, a shut-off needle guided in the channel for shutting off the nozzle, and a needle drive for moving the shut-off needle.

The pneumatically or hydraulically controlled nozzle type HP (High Performance) has a needle shut-off which stops the melt stream directly at the mold interface. The HP nozzle is adaptable with several different technologies such as; MuCell® and other physical foaming procedures or melt pre-compression. Productivity factors

Shut-off nozzle in plastic injection molding

The needle keeps the nozzle orifice closed by spring pressure. When the injection pressure increases, the melt will push back on the needle head and try to open the nozzle. Once the melt inside the nozzle reaches a certain amount of pressure, it will succeed in pushing the needle back against the spring.There must, therefore, be a minimum pressure for the opening process to overcome the force
