End-of-Barrel Products

Conventional molding:

Control nozzle temperatures without freeze-up or drool. Speed recovery rate and reduce cycle times. Inject into parting line to eliminate sprue and cut material usage. Permits structural foam molding.

Gate directly into part:

Cut material use and lower tooling costs by eliminating the sprue and runner. Cut start-up time. Faster color changes than hot manifold method.

Gating through core:

Eliminate gate blemishes on large parts where cosmetics are important.

Three plate mold design:

Eliminate sprue by injecting directly into runner system. Eliminate stringing and poor ejection of runner system. Mold runs automatically.

Vertical injection molding:

Cut material use by injecting through the parting line

A field-proven Performer at stopping drool, reducing scrap, and reducing cycle times in these applications:

Why the patented EMI design out-lasts and out-performs every other shut-off nozzle.

With spring-operated valves, you cannot positively control shut-off because spring-operated valves are dependant on injection pressure. With heat variations, springs fail prematurely. The springs themselves actually restrict resin flow and make color changes more difficult. Single air valve designs wear unevenly at the cross- arm and pin, which loosens the shut-off seal making them prone to leaking, drooling, and expensive maintenance. Hydraulic-operated valves have seals which may leak oil onto heater bands and other heated surfaces which may flash fire. EMI Performer nozzles give you a dependable, positive open-close design which cut cycle times, last longer, and operate safer than other nozzle types. What is your plastic melt injection pressure? (Not the hydraulic system pressure). If under 18,000 psi, any of the Performer series shown can be used. If over 18,000 psi, but less than 30,000 psi, use the 2900 Series. What type of material is being processed? General purpose materials with no fillers can be processed through any Performer. For materials which are corrosive, have additives or are shear sensitive call EMI. Measure to determine which series nozzle will fit your platen. Note the overall "A" dimension on the drawings. (The minimum OAL can be reduced further by building a combination one- piece machine adaptor and end cap).

Pick the right Performer shut-off nozzle for your process

Selection of the right Performer nozzle is based on your injection pressure, machine size, flow rate, sled travel and material. Answers to these questions will help determine nozzle selection: 1. 2. 3.
