In the modern era, Die Casting is facing new challenges to produce defect free castings with intricate & complex profiles. This demands cutting edge technologies to improvise die casting techniques”
Cooling plays a vital role in producing superior quality castings and resulting into higher life and efficiency of dies and equipments of die casting.
RAGA offers customized cooling solutions to the die caster.
- High Velocity Cooling Machine
- Water cooling.
High Velocity Cooling Machine
The PRO series high velocity cooling machine by RAGA is an equipment for die casting to improve casting quality, cast intricate parts and reduce casting rejections.
- HV-PRO cooling machine is synchronized with the die casting machine to work as per the die casting cycle.
- Machine injects water and air cyclically at high velocities into the core pins of die casting mold. This effects into elimination of soldering and shrinkage.
- The system is provided with a high pressure cooling pump and a over cooling prevention mechanism.
- HMI (Human machine interface) of the machine lets easy set ups of cooling cycle and operation is by touch panel method.
- HV-PRO coupled with jet cooler can cool small diameter core pins.
- Maximum number of cooling pins: 20
- Different cooling cycles for fixed and moving die. HV-PRO can memorize cooling patterns for about 25 types of die products. Suitable for die casting with frequent die changes.
High Velocity Cooling System
Micro Analysis of poor casting quality revealed defects like:
- Soldering on Core Pins, Profile Punches & Sliders.
- Shrinkage porosity at cross sections.
- RAGA’s comprehensive High Velocity Cooling System integrates with a Die Casting machine & keeps castings away from such defects.
Characteristics of High Velocity Cooling System:
- Cooling of a small diameter core pin was not possible in the past. HV Cooling System has make it possible.
- For up to min. Dia 4 of the pin outer diameter, a cooling channel can be formed. Special thin cooling tube “Jet Cooler” is available.
- Cooling water can reach the core pin tip without overheating.
- Air purge is made to prevent over cooling.
- Cooling pattern can be selected at the option and cooling time can be controlled in each system.
- The system becomes operative simply by connecting to the power source integrated with the die casting machine, water and air
Jet Cooler Core Pins
- Deep holes are created in core pin ID till casting diameters.
- Depth of holes & diameters are optimally selected.
RAGA’s comprehensive High Velocity Cooling Machine integrates with a Die Casting machine & keeps castings away from such defects.
High Velocity Cooling machine Primarilly consists of: Jet Cooler, Jet Cooled Core Pin.

“RAGA’s R&D & Design with State of the art cnc/spm manufacturing and inspection facility carry out continual research into application of Plunger tips. The ongoing quest for optimizing Shots has lead RAGA to indigenous and innovative designs for Plunger Tips”
Copper Alloy Plunger Tips:
RAGA's unique integerated designs of copper Alloy Plunger Tip the best of wear, thermal and mechanical Properties. This break through tip gives immense value to die casting as compared to casted copper Alloy Plunger Tips.

Standard Plunger Tip PT
The bi-metal plunger tip is made by plasma surfacing process. The
bi-metal plunger tip has excellent characteristics of anti-wear and
thermal fatigue under high temperature
The bi-metal plunger tip can work longer time, its life is about 10~20
times of plunger tip made by cast iron, 4 times of plunger tip made by
tool steel. This plunger tip has been used in die casting from last ten
years. The analysis of the results have indicated that the combined
effect of one machine was about Rs. 10 lacs/year from saving of tip’s
direct cost, reduced down time for plunger tip change and decreased
“The interaction between Plunger tip and Shot Sleeve is the most critical in the die casting process”

Plunger Rod Assembly
Impact of Plunger Rod assembly:
To maintain consistent thermal and thus dimensional control of the plunger tip, it is necessary to closely manage the flow of cooling water through the plunger during the casting cycle. Dimensional problems can often be resolved by simply increasing the flow of water. The rate of flow of cooling water is easily measured, and should be monitored frequently. Rate of flow is much more critical than the temperature of the cooling water. An adequate flow of coolant through the plunger rod can lead to:
- Efficient heat transfer in plunger tip.
- Avoid excessive plunger tip wear.
- Reduced biscuit solidification and cycle time.
- Longer shot sleeve life.
