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 due to its own elasticity and due 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.

Key features and benefits

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.

Engineered Ring – made with softer steel prevents sleeve damage and allows smooth sliding of the spring bush.

Reduced Cycle Time – enhanced thermal control accelerates biscuit solidification, enabling shorter cycles without compromising part quality.

Up to 3 Times Longer Service Life – custom developed tool steel and optimized cooling significantly reduce thermal fatigue, wear, and heat checking.

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.

Cycle Time Reduction

Superior thermal management characteristics

Due to the superior thermal management characteristics Performa Plunger usage results in up to 15% shorter cycle time.

KEY FEATURES INCLUDE
Cooling channels customized according to plunger thermal management requirements.Enhanced design flexibility for cooling channels compared to a conventionally made plunger; Performa plunger enables extra flexibility to bring cooling channels near the critical zones.
More uniform heat distribution across its surface, leading to faster and more even cooling compared to conventional plungers.

Shorter Downtimes

Plunger Ring and Spring Bush

Enhanced Durability: Fewer Replacements, Less Downtime
Plunger rings help to streamline operations and reduce costs by decreasing the need for frequent changes and repairs.
Compatible hardness:
Using the same materials for the sleeve and ring minimizes friction and wear on both components, extending their lifespan, leading to less downtime. Opens during injection due to its own elasticity and due to aluminum penetrating between ring and plunger. The ring's assembly and removal is quick, and can be done directly on the machine, minimizing downtime.

Longest lifetime in 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.
