ENDURA T-RS

range ø50 to ø260 mm

Endura

Versatile and robust plunger solution with patented cooling system

1. HOT WORK TOOL STEEL BODY

Made with hot work steel that is widely used in hot work tooling applications. Excellent combination of high toughness and resistance to thermal fatigue cracking (also known as heat checking).

2. STEEL RING

Opens during injection due to its own elasticity and due to aluminium penetrating.

3. STEEL SPRING BUSH

Ensures contact plunger/sleeve at the back of the plunger due to its own elasticity.

4. STAINLESS STEEL HOLDER

Fixed to its holder with a special bayonet locking design.

CONDUCTA B

CONDUCTA B-R

CONDUCTA B-RS

range ø40 to ø260 mm

Conducta

High conductivity and customization possibilities.

1. CuBe BODY

Made out of forged CuBe. Excellent combination of toughness and highest values of heat transfer.

2. STEEL RING (optional)

Opens during injection due to its own elasticity and due to aluminium penetrating between ring and plunger.

3. STAINLESS STEEL HOLDER

Fxed to its holder with a special bayonet locking design.

VACUUM AND GLIDING EFFECT

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

PERFORMA T-R

PERFORMA T-RS

PERFORMA T-R/BN

range ø40 to ø260 mm

Performa

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.

Rod Spray
