ARP plunger

ARP Plunger is produced using high strength Cu-Be alloy.

The plunger is fixed to its holder using a special bayonet locking design.

Inner channels are specifically designed to achieve optimum cooling during the injection process.

ARP Plunger is available in 2 versions depending on casting process and application:

ARP-F: Solid plunger with bayonet fitting
ARP-R: Ring plunger with bayonet fitting and a replaceable frontal ring

HTS DIFFERENCE

INNOVATIVE TECHNOLOGY

Based on MFT™ and DED technologies we produce components with conformal cooling / flow design and mechanical properties of a forged tool steel block.

SUPERIOR PERFORMANCE

iTherm® components have a big impact on cooling and material flow, resulting in shorter cycle times, higher cast/moulded part quality and subsequentially also productivity.

SOLUTION ORIENTED

Years of experience and R&D of HTS Group companies, combined with leading OEM customer partnerships gives us knowledge and capacity to help you improve your productivity.

Advantages over conventional plunger

Assembly allows minor misalignment

In comparison with a conventional lock system between plunger and holder, the coupling is done using a special bayonet system. This one provides a small functional play between both holder and plunger, compensating for small misalignments.

Cycle time reduction

Compared with a conventionally made plunger, the cooling arrangement is optimized, resulting in more efficient and homogenous cooling and solidification of the biscuit.
Assembly and removal of the ring are straightforward and can be done directly on the machine, avoiding any waste of time.

Longer lifetime

The assembly of the ARP plunger with its holder has been specially designed: the holder itself rests against the inner surface of the plunger absorbing the total injection pressure and avoiding cracks and fatigue.
