ATS plunger

ATS Plunger is produced using high strength hot work steel.

Its cooling channel shape has been specially designed for an optimal cooling during the injection process.

ATS Plunger is available in 3 versions to best suit the various types of casting process and applications.

ATS-F: Solid steel plunger with thread lock system
ATS-R: Steel ring plunger with thread lock system and a replaceable frontal ring
ATS-RS: Steel ring plunger with thread lock system, one replaceable frontal ring and one replaceable spring bush (back 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

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.

Vacuum and gliding effect

ATS-RS version includes a spring bush (back ring) which has been specially designed for vacuum systems.
Made with softer steel, the spring bush slides easily and doesn’t damage the inner surface of the sleeve.

PARAMETERS

Dimensional range

Diameter 50 - 90 mm (2.00" - 3.50")

MATERIAL

ATS plungers are made using high strength steel alloy. The alloy has a high tensile strength and 80% higher thermal conductivity than a 1.2344 / H13 hot work tool steel.

Plunger rings

We manufacture a selection of plunger rings and spring bushes for ATS model plungers. Read more…

iTherm® conformal cooled shot blocks are cooling quicker and more equally across the working surface, shortening biscuit solidification time.
