Performa Plunger

HTS DIFFERENCE

CONFORMAL DESIGN

Manufatured with proprietary additive manufacturing technology based on conformal cooling principles.

SUPREME TOOL STEEL

Made with specially developed hot work tool steel for best combination of tougness and resistance to heat checking.

UP TO 3 TIMES LONGER SERVICE LIFE

Custom developed tool steel and optimized cooling significantly reduce thermal fatigue, wear, and heat checking.

ENGINEERED RING

Made with softer steel prevents sleeve damage and allows smooth sliding of the spring bush.

NO PREMATURE SOLIDIFICATION

Precisely managed plunger tip temperature reduces heat loss from the alloy, preventing cold shuts, short shots, and incomplete filling.

STABLE VACUUM CONDITIONS

Optimized plunger cooling delays solidification near the gate, supporting reliable venting and consistent vacuum pressure throughout cavity filling.

Performa Series: Customizability & Unprecedented Strength

1. HOT WORK TOOL STEEL BODY
Made with supreme hot work tool steel, using HTS proprietary additive manufacturing technology that allows the implementation of the conformal cooling. Excellent combination of high toughness and resistance to thermal fatigue cracking (also known as heat checking) results in high cooling power >> reduction of cycle time and highest lifetime on the market.

2. STEEL RING (optional)
Opens during injection thanks to its own elasticity and thanks to aluminium penetrating between ring and plunger.

3. STAINLESS STEEL BUSH
Ensures contact plunger/sleeve at the back of the plunger due to its own elasticity.

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

 

 

Advantages over conventional plunger

Enhanced design flexibility for cooling channels

Compared to a conventionally made plunger, Performa plunger gives you extra flexibility to bring cooling channels near the critical zones.

More uniform heat distribution on the working surface

The Performa Plunger ensures more uniform heat distribution across its surface, leading to faster and more even cooling compared to conventional plungers.

Longest lifetime on the market

The conformal cooling of the steel allows the heat removal rate to surpass that of BeCu tips while extending its lifetime due to low transient stresses in the membrane.

Our customers have reported:

Prevents premature aluminum solidification

During the pouring stage, the Performa Plunger maintains a higher temperature than other plungers, due to the low heat capacity of its steel membrane, preventing early aluminum solidification.

Rapid biscuit cooling

Due to high Performa Plunger cooling effectiveness, extreme temperature drop occurs in the injection/pressurization phase, resulting in rapid biscuit cooling

Cycle time reduction

Due to the supreme thermal management characteristics of Performa Plungers, their usage results in up to 15% shorter cycle time.
