Round Dripper Mould
A full hot runner mould for cylindrical and pressure compensating drippers used in long life drip pipe.
RAL 5021 · semi-matt finishProduct introduction
How the Round Dripper Mould is engineered, and which sub-assemblies protect the performance your customers actually buy.
Round or cylindrical drippers are larger than flat drippers and need a mould with deeper cavities and a carefully balanced hot runner. The part must be dimensionally accurate because it is welded into the pipe wall and has to seal against the pipe bore.
BENK MACHINE builds round dripper moulds in full hot runner configuration with imported temperature control, so the shot is clean and the cycle is short. Both standard and pressure compensating dripper designs can be tooled, including the more complex geometries needed for diaphragm compensation.

Technical advantages
Every sub-assembly below is selected to protect the performance your customers buy.
Full hot runner
Imported temperature control keeps the melt uniform and removes cold slugs from the shot.
Deep cavity capability
Five axis machining and EDM produce the deeper, more complex cavity forms that round drippers need.
Pressure compensating designs
Tools for diaphragm type PC drippers are designed around the compensation geometry, not adapted from a standard part.
Accurate sealing surfaces
Cavity finish and dimensional accuracy ensure the dripper seals correctly when welded into the pipe.
Warranted life
Moulds carry a warranty of five million shots or more.
Complete support
Hot runner spares, cavity replacement and service are available for the life of the tool.

Why buy from BENK MACHINE
Extrusion specialists, not traders
BENK MACHINE designs and builds extrusion and drip irrigation equipment in Zhangjiagang with an in-house R and D and process team, so machine selection is matched to your resin and product instead of a catalogue number.
Evidence before shipment
Every machine is assembled and run in our works. You receive trial video, gauge and output records, and are welcome to attend the factory acceptance test.
Total cost, not lowest price
Energy efficient drives, permanent magnet motors and optimised heating reduce kWh per tonne, which usually matters more over five years than the initial purchase price.
Real commissioning support
Our engineers install, commission, train your operators and stay involved until the machine hits the specified output and quality on your material.
Spares and response
Critical spares are stocked for fast dispatch, and the Siemens Ethernet control platform allows remote diagnosis before a service visit is needed.
Upgrades as you grow
Co-extrusion, gauge control, automation and downstream equipment can be added later, protecting your original investment.
