Screw Tips for Moulding Machines

Telford Smith Engineering manufacture a complete range of world-class components and quality parts for the extrusion, injection and blow moulding industries.

A complete range of non driven, driven ring check valves and ball check valves are available. All Ring Check Valve assemblies are manufactured from a high grade alloy steel, which is hardened and nitrided for maximum service life. Rings are precision ground to finished diameter ensuring a close tolerance fit with the barrel bore, this reduces back flow over the ring thus ensuring consistent shot rate and volume.
In many cases they are in stock to minimise delays in production. The proven Johns MK 2 design are in stock in sizes ranging from 1.5? to 3.875? diameter.

Other designs for the most popular brand moulding machines are also carried in stock.
Alternatively, we can manufacture to order from a customer sample or drawing. If these options are not available we can draw on our extensive data base to establish an appropriate design.
Telford Smith Engineering manufacture standard nozzles & nozzle nuts to suit any injection moulding machine.

In addition, we offer spring actuated or hydraulic actuated shut off nozzles with mixing elements or melt filtration as a built in option from Xaloy USA.
